Light Bee Ownership Review Summary
Review Summary
To me, the Sur Ron is as close to the perfect motorized two-wheeler that fits right between a full-suspension mountain bike and a small displacement ICE (Internal Combustion Engine) bike. Much like the original iPad, the Sur Ron has carved out its own niche in the EV two-wheeled space. Incredibly well-engineered and executed, this piece of kit from China approaches Honda quality. Fun factor surpassed all expectations. Plug it in to charge it, turn the key, and roost away on your favorite trail or road. I took a half a star away simply because parts are not yet readily available if I break something… like a brake lever grip or footpeg mount. Luna does stock them when Sur Ron can get them the part.

Unlike some owners, I don’t use my bike for commuting to and from work. Many owners do. Nope mine is just for recreation, so after a year the 1,956 miles amassed to date are just fun miles.

1,956 miles so far on the Sur Ron

There are plenty of articles, forums, and videos about the Sur Ron Light Bee. I wanted to write a ‘long term’ (as long as 12 months is…!) about my own experience with the electric bike. You can find the bike’s stats, measurements, etc. anywhere on the web.

Sur Ron Light Bee June 13, 2018 to June 13, 2019

I wanted to write about my actual time and experience with this incredible piece of engineering rather than just facts and figures. I find that so many articles are only written when a product first appears in the marketplace. That’s fine, but what I want to know is what the experience is long after a product’s initial release. You know, after the bloom is off the rose….

First I’ll give a little background about my own riding experience and history. I’ve raced motocross at Saddleback Park, Carlsbad, and desert racing too – the Barstow to Vegas race twice, and club road racing. I eventually went on to teach road racing.

I purchased my Sur Ron Light Bee from Lunacycle on April 12, 2018. I had to wait because they were back ordered on the color I wanted, steel grey.

The Arrival

Mine arrived two painful months later via FedEx Freight on June 13, 2018, and boy was I stoked! I felt just like a 12-year-old boy seeing his first Playboy Magazine. Well, maybe not quite that excited…

I had originally planned to fly down to El Segundo where Luna is located to actually view the bike since I live in the San Francisco Bay Area. It would have been a relatively inexpensive flight into LAX. LA is where I grew up and I knew Luna was just a short jaunt from the airport.

Unveiling the Sur Ron Light Bee from its shipping package

But after watching Jackson do a teardown of the bike I opted to not fly down to see the bike before I purchased it. He seemed sincere and honest in the video and besides, what I witnessed in the video was impressive.

Mind you I have never purchased something this expensive sight unseen! I’d been burned by prior crowdfunding campaigns, but this was different. It is NOT crowdfunding; it’s a real bike from an actual brick and mortar company.


Assembling the bike was very straightforward and there was an excellent YouTube video about how to go about doing so. I was very impressed by the build quality. It was just as Jackson had described in his YouTube video.

My personal assessment of the build quality after having worked on Yamaha, Bultaco, Penton (now KTM), Maico, Kawasaki, Suzuki, and Honda motorcycles, is the Sur Ron’s build quality approaches that of Honda. Captured fasteners instead of loose nuts, precise alignment of fastening holes, excellent welding; basically high-quality engineering and manufacturing.

I was very intrigued by the rear shock linkage. Rather than just a direct link between the swingarm and shock, Sur Ron had designed a progressive linkage system which is much more in line with current motorcycle technology. It made me very anxious to test it out once assembled.

After inspecting all of the bolts I surmise that in China the Sur Ron Corporation must have hired several two thousand pound gorillas to torque down the fasteners! Seriously all of the fasteners are way overtightened. It’s great they’ve used blue Loctite on the fasteners, but with the amount of torque put on them…. why?

Riding the Bike

My First Worrisome Encounter

I ran into a worrisome issue during my first week of owning the bike. It would intermittently stop running while I was riding. There was no rhyme or reason for the sudden failure.

Sometimes it happened immediately as I was leaving my garage with a 100% charge. Other times it would happen when I was 10 miles out on a trail with 60% on the battery. The headlight and speedometer were still illuminated, but the bike would not move forward at all.

In each case, if I turned the ignition off and then back on it would run. The culprit ended up being the brake cut off sensors. They are threaded into the brake master cylinders and held in position by a very tiny set screw.

The front brake’s set screw was loose which caused the magnetic sensor to move in and out of alignment causing the cut-off. I removed both sensors and after that everything was fine.

There are three more sensors on the bike, a tip-over sensor located just above the controller, a throttle return sensor and a kickstand sensor. I’ve retained all of those on my bike without issue.

The culprit, the brake cut off sensor.

Filling cut off hole with Instamorph

I filled the cut off sensor hole with Instamorph.

When people ask me about the bike there are always two questions:

  •  How much does it cost?
  •  How far can you go on a charge?


The range of my bike will vary depending on the terrain where I’m riding, my speed and the use of the throttle. The more I’m at full throttle, the less mileage I get. The steeper the terrain, the less mileage I get. Makes perfect sense, doesn’t it?

There are only two modes on the bike, EP, and Sport. (No idea what EP stands for btw) EP mode cuts the amount of electricity in half which results in less acceleration and power. I occasionally use EP mode when Sport mode is not needed to extend my range.

So without any regard for mileage or conserving throttle and running in Sport mode in varied terrain/surfaces (hills and loose sand or dirt), I can COMFORTABLY get 20 miles. And for those who have never ridden HARD off-road – 20 miles is a LOT of miles.

In EP mode on the street, I have gotten 43 miles no issue. And as I’ll explain later on, before I replaced the OEM seat 20+ miles is torture on your tush!

The bike’s BMS (Battery Management System) has a safety feature. If you are riding in Sport mode and your battery level falls below a certain percentage, the BMS automatically switches you to EP mode.

I say a ‘certain percentage’ because I’ve had my bike go into that mode anywhere between 13% to 21% as indicated on my battery’s charge indicator. It just meant that I had to ride back to my starting point in EP mode instead of Sport mode. No big deal for me.

Battery indicator on battery

This is the battery indicator on the battery itself, not on the speedometer panel. My understanding is the newer models automatically illuminate this panel whenever the ignition is turned on.

Mine does not, you must press the little button to the right to view the battery indicator. I’m not certain how accurate this gauge actually is in measuring the state of charge remaining. Just FYI.

Although this has never happened to me if the battery gets so low that when you place it on your charger and it does not take a charge, there is a procedure to ‘jump start’ charging your dead battery pack. That has been covered in this YouTube video shown below.

And from almost dead to a full charge has taken me just a tad under 3 hours to get my battery pack up to 100%

First Few Months

I rode my bike box stock for the first four months. I was impressed when adjusting the suspension’s compression and rebound adjustments. It was fun to do and resulted in varying degrees of traction.

I was having a ball and marveled at the power and lack of weight to the bike. It felt like a true cross between a full-suspension mountain bike and a small displacement ICE (internal combustion engine) bike.

Oh and the lack of noise! I live in a suburb of the Bay Area and because the bike is darn near silent I can ride at night, right next to homes in an area called “Bump City” which is this cool area kids ride their BMX bikes, people fly their model airplanes and others drive their remote-controlled cars.

The Sur Ron at Bump City in the Bay Area

Since it’s next to the Bay yet surrounded by homes riding an ICE bike would be reported to the local PD immediately, especially at night. Because the area is very popular, I try to go there during the workweek, later in the day or in the evening when I have it all to myself.

As I’ve mentioned before I was an admin on the private Sur Ron Facebook page. One of the primary questions potential buyers had was is the bike large enough for anyone 6 feet or taller. The short answer is yes. Many of the owners were 6-3 and simply installed taller handlebars.

Performance Modifications

One of the pleasures in owning the Sur Ron is its ability to be modified. Unlike a bicycle which for me is too simple mechanically or a regular motorcycle which at this point in my life is too much of a hassle, the Sur Ron is just right. And this would be a good time to say that the Sur Ron Light Bee occupies a space that in my mind did not previously exist. Let me explain.

When Apple introduced the iPad many folks tried to pigeon hole it as a phone and then as a laptop. Because it fell right in between those two devices, people just didn’t know what to do.

In my mind, the Sur Ron is currently in the exact same situation. Not a bicycle and not a motorcycle. People are trying to see how it compares to a KTM-xxx or a Honda-xxx. The reality is it’s neither. It has created a space that’s new, just like the iPad created the ‘tablet’ space.

I’ve modified my bike because of what and where I ride most often. I’m spoiled having ridden and raced on excellent motorcycle suspension and although my racing days are long over, that’s what I wanted for this bike too.

My modifications in my own order of importance:

Performance mods

  1. X controller with Regen
  2. Forks/Headset – Manitou Dorado Pros
  3. Cane Creek headset purchased from Luna
  4. Ohlins TTX22 Rear shock
  5. 21” Front wheel custom laced
  6. 225mm floating front rotor (OEM is 203mm)

From 19 to 21

In terms of hill-climbing ability, this little bike reminds me of the Little Engine that could! It just keeps climbing and climbing and climbing! The only limitation to its climbing ability is traction at the rear wheel.

Because the OEM tires are 70/100 19” they are thinner than off-road motorcycle tires, but then again this is NOT a normal motorcycle. The rear tire wore out rather quickly, but the front remained fine.

Because I ride in such a wide variety of terrain I opted to switch to a dual-sport tire. One that is good on all the surfaces I normally encounter. If I was ONLY riding in deep sand or mud, I’d have opted for knobby only tires. Instead, I switched to Shinko 244’s and have been very happy with their performance.

I also opted to have a custom 21” front wheel built for me. Why? Well because the Sur Ron’s parts are primarily mountain bike units the 19” front rim had limited tire choices. A 21” front rim is the defacto size for off-road motorcycles, so the tire selection is endless.

Plus I felt the handling would improve for what/how I ride over a 19” rim. When I presented my thoughts to others on the FB group, they all said: “Oh, that will be too heavy.” Yet when I asked all of them “What handling issues did you find when you rode a 21er on the bike?” SILENCE.

Not any of them had actually ridden a Sur Ron with a 21” front rim/tire. It reminded me of forums where so many people like to pretend they know, yet don’t actually know. So for me, I will simply say that the change is wonderful for what/how I ride.

The front end is more planted in turns, especially those that are off-camber; rutted fast downhills are much more manageable with the 21er. I love it.

For 3500.00 I’m damn impressed with the suspension. The suspension offers eight inches of travel in both the front and rear. Compression and rebound are adjustable on both the forks and the shock. That comes standard? Really?!

Heck even on all of my motorcycles if I only had rebound on the stock suspension I was impressed. Mine came with the RST forks which use springs rather than air springs. My rear shock was the FastAce brand. Both were completely fine for street riding, smooth dirt, fire roads as well as small bumps or medium jumps.

The reality is most people NEVER USE 100% of a suspension’s capability. And if they think that the primary function of suspension is to dampen bumps and landings off of jumps, well…..there’s so much more to it than that. Is it necessary to change the suspension if you’re going to ride it on the street or other areas I specified above? Oh hell no.

Having raced on Ohlins forks and shocks in my road racing days, the plushness and ability to keep constant contact with the surface was heaven for many aspects of going faster more safely. Good suspension does that. So switching to Dorado’s first then highlighted the weakness of the rear shock. So I opted to replace it with an Ohlins TTX22 with a 502 lbs. spring for my weight.

How do those changes in suspension manifest themselves? Well in turns that are off-camber, or very loose in surface I am able to hold a line much better than before. And I can both brake later and increase acceleration earlier exiting a turn.

And over bumps… man the bike is just plush, reminiscent of my full Ohlins suspended race bike. For me, handling and braking are much more important than adding power. Everyone is different though.


The single element of the Sur Ron I felt was subpar compared to the rest of its construction was the headset. So when I opted to replace my RST forks with Dorado Manitou Pros I thought it was a good time to change the headset to a seal bearing type from Cane Creek.

The OEM bearings are retainer type ball bearings and although mine did not feel loose or bind, I just felt more comfortable replacing them with a sealed bearing configuration.

Cane Creek seal bearing type


Some people on a private Facebook Group complained about the brakes on the bike. The complaints were about the brakes feeling ‘spongy’ or the lever almost reaching the handlebar grip during stops.

Having come from a racing background I know the value of properly bled brakes, bedding pads in properly and so forth. I did both of those things to my bike before I started riding. I did a bleed of the brakes, which use mineral oil just like most mountain bikes because they are mountain bike brakes.

I also bedded my pads in properly. If brakes are experiencing a spongy feeling or the lever is almost going to the grip before stopping, it’s an air in the brake line issue.

To date, I have the OEM brakes and am very happy with their performance. They’re four-piston binders which work very well, have great modulation and stop the bike securely. I have changed the brake pads to an organic compound which does not last as long, but I prefer the feel and modulation of organic over semi-metallic or full metallic.

It’s just a personal preference. I believe many folks feel that if brakes bite hard at the beginning, they feel the brakes are “powerful.” I too like power, but without subtle modulation, it’s not my personal preference.

I prefer a larger floating rotor for more power and modulation.

USA Gen1 X Controller

About six months into ownership Luna was offering a limited number of X controllers. They were of the sine wave rather than the controller that came on my bike – the square wave type. And the X controller offered regenerative power and braking too!

To explain, imagine a sine wave like a nice curved chart. The power ramps up to a smooth curve. A square wave has a sharp edge in terms of acceleration.

Sine Wave Chart Square Wave Chart

Sine Wave & Square Wave

I happened to be one of the lucky 50 who got the X controller with full regenerative power and braking. The smoothness of the throttle is very different than the non-X controller. It is as smooth as a well-tuned ICE throttle and the ‘engine braking’ (regen) is like third gear deceleration on a four-stroke bike.

In a non-X controller bike, there is a definite hit when you engage the throttle. It is not smooth and letting off the throttle makes the bike coast like a bicycle, no deceleration unless you’re braking.

I’m sorry to say that all X controllers in the US, EU, AU, and others with X controllers did not offer regen in the controller. The smoothness is there, just no regen. I feel damn lucky and happy to have one of the Unicorn X controllers! I hope Sur Ron brings them back for all future Xers too.

My friend Matt who is one of the admins on the private Facebook Group created an excellent video comparing and testing the X and Standard controllers (shown below). Not only does it illustrate the performance differences, but the regenerative power put back into the pack.

Update as of June 2019, my understanding is Sur Ron did enable regen on new X controllers, but to what degree I’m not certain.

New X Controllers

Comfort Modifications

  • Renazco custom seat – the OEM seat is a torture rack!
  • ProTaper 3” rise handlebars – I wanted a more upright riding position
  • Fischer Fab House Headlight – I ride a lot at night. Trail riding is very different than street riding for the amount of illumination necessary.

The vast majority of my riding is off-road. I am very fortunate to have a wide variety of choices which are a very short distance from my driveway. As a matter of fact, I only have to ride on 0.8 miles of public road to get to off-road areas or a bike path.


After about a month I noticed that my ass was killing me after only 25 minutes of riding! The OEM seat is only 5.5 inches across at its widest point. And my butt resides in the back portion of the seat where the padding is much thinner than in the middle. It’s not a big bike and I’m not a big guy at 5-8 170 pounds with a 31” inseam.

So I found a craftsman who makes custom dual sport seats, James Renazco Racing in Santa Rosa, CA. I wrote to James, sent him my measurements, weight and my seat pan. He called to discuss fabric options and when I got my new seat I was in heaven.

Renazco Racing TempurPedic foam seatHe used suede on the top to keep me from sliding during braking or acceleration, leveled out the seat’s forward slope and used TempurPedic foam instead of the foam in the OEM seat. He told me that the OEM seat pan is better made than many of the motorcycle seat pans he’s worked with.

That’s good news. And man the difference is night and day in terms of comfort. My battery runs out before my butt does now.


The OEM handlebars are very flat mountain bike type bars. I wanted a more upright seating position as well as to not lean as far forward on descents. So I replaced them with the Answer ProTAPER 810 Handlebar 3″ Rise 31.8 Black.

The Fisher Fab House headlight has several different levels (80 lumens and 750 lumens flashing not shown). Illumination on the street is VERY DIFFERENT than lighting needed out on a trail in total darkness.

So the OEM headlight, although fine for the street and most venues was inefficient for where I ride at night. The OEM headlight does NOT have an on/off switch, it remains illuminated whenever the bike ignition is on. Same with the rear tail light.

Moped Plate – California

I had applied for and received a California moped plate which I use when necessary. Whenever I go to OHV parks it is required to have either a Red or Green sticker or a valid CA license plate.

Most jurisdictions don’t yet know how to classify these or any other electric vehicle so having a plate is the easiest method. Plus in CA there is no annual renewal fee for moped plates. $21.00 for the life of the vehicle is a sweet deal in my view!

I ‘originally’ installed the plate when riding on public roads and then removing it when off-road or on bike paths. But what I discovered is leaving the plate off works best for my use. I have the pedal kit (I would not have purchased it had it not offered the pedal kit) so it ‘looks’ like a bike.

Sure there are ‘some’ who poopoo the pedal kit and I understand that. It does NOTHING to propel the bike anyway. But when I’m on MTB trails or on bike paths people look at the bike, but when they see me ‘pedaling’ it’s no big deal. But as soon as anyone sees a ‘plate’ then how the bike is viewed is very different.

I like having the option of having the plate, but in reality, I use it to enter OHV parks or when I’m just going to ride on public roads. But even then I like being viewed as a bicycle.

Moped plate on rear of bike

And I use to switch back and forth between the pedal kit and pegs, but now I don’t. I’ve become accustomed to where they are and it’s no big deal anymore.

I knew a racer who lost both of his legs due to an on-street accident. He figured out how to configure his 900RR to adapt to his new disability and still raced! If he can do that, then I could get used to pedals versus pegs. Enough said on that, I’m no princess.

How I Transport My Sur Ron

When I want to transport my bike the OHV parks or to take it with me I use my e-bike rack. Yep, no need for a truck or trailer!

Yep the bike fits nicely on my Thule bicycle carrier.

In Conclusion…

Sur Ron Light Bee

I want to mention that my own experience is with the Sur Ron which is imported into the United States by Luna Cycle. The EU and other countries have Sur Rons that have been homologated for street use having different head and brake lights, turn signals and reflectors as well as a different instrument panel. I have no knowledge or experience with those versions.

The Sur Ron is a remarkable bike, remarkable. Its fun factor is unmatched by any machine I’ve owned or ridden. I will simply say that after a year of ownership I would not hesitate one moment to recommend this bike to anyone who wants one.

If I only had enough money to make one change to a box stock bike it would be to upgrade the seat. I cannot stress enough how uncomfortable I found that thing to be! And anything that takes away from me having seat time on this bike irritates me to no end …and in this case, it irritates my butt to no end too!

I left Facebook and developed a website to assist other Sur Ron owners or potential owners with the experience I’ve amassed in a year of ownership.


  • FUN & FAST
  • Reliable
  • Just come home and plug it in
  • No fluids/transmission/noise/smell
  • Easy to move around
  • Did I say fun?
  • Lightweight
  • Unintimidating
  • I get tired before the battery runs out


So what are the downsides I’ve experienced in a year…. hum….

  • Spent too much time tinkering when there was no need to do so
  • Attracts attention
  • Trying to avoid talking to people about the bike when I stop
  • Easy to pick up and steal by throwing it into a van
  • No real luggage storage options
  • Going over the handlebars while jumping without my full-face helmet on – concussion
  • Seriously I have really tried to come up with some downsides. OH, I swallowed a bee because I was smiling! Man, that was weird!

      1. Mark, thank you for the detailed list of the costs of the modifications, much appreciated! -Ed

        1. Ed you bet, sorry if it affects your pocket book! Keep in mind the only two items I feel are necessary is the headset and the seat. Other than that, not much is needed.

          1. Right on Mark. This is great info for any potential Sur-Ron owner. I already own an Alta MXR and love it. I’m following all the exciting developments in the e-moto world and I think the Light Bee has a nice little niche carved out. I’ve also been reading recently that Sur-Ron is developing a larger e-moto dirt bike that is closer to a full sized dirt bike. Will be interesting to see the final specs and reviews on that once its released.

  3. No mention of the quality issues? Join the face book sur ron group and you’ll notice that like 40% of the posts are about how the bike suddenly stopped working.

    1. Jim, I was a former ‘admin’ on the private FB group. When I left FB about four months ago ‘some’ members were having issues with their BMS, but I don’t recall it being even close to 40%. That was when the group consisted of approximately 1600 members. At 40% that would equate to 640 people albeit ‘some’ of the group members were not yet owners. I doubt that number, but perhaps you have researched that percentage….

      Not sure if what you are sighting is a new issue, but I have not had any power cut off issues other than what I specified in my write up on the brake sensors. 2300 recreational miles only to date. Other than the brake sensors, NO quality issues from my bike.

  4. I notice you have a water bottle holder on there as well. What type is that? Or do you have any recommendations for how I can add a storage bag to my bike?

  5. I would like to learn more about your front 21″ wheel. Who built the wheel and is the front hub a standard MTB part?

  6. Hey Mark,
    What model of a thule e-bike rack do you have? Could it carry even two surons? What weight limit is to it?

  7. Have you taken a look inside your suspension linkage?

    We have a few Sur Rons on the We(s)t Coast of Canada and have been riding them for about a year.

    I took apart the suspension linkage to see what would be involved in making another one (to raise the seat height). The needle bearings inside were completely corroded and did not turn. With a lot of carb cleaner I was able to get them spinning again but they’ve seen better days.

    I imagine all Sur Rons will have this problem and they should probably be checked and greased often.

  8. James it is my understanding that both Luna and Stag in the UK are making or have made replacement bearings for the shock/swingarm linkage. I service mine quarterly as just routine maintenance. Compared to my ICE bikes, hardly anything needs to be serviced regularly! LOL

  9. Just as an update as of May 28 2020 I have 3980 miles on my bike. No issues whatsoever. Lube the chain, check the spokes and adjust tire pressure for where/how I’m riding. Incredibly easy compared to my former ICE life. And if it weren’t for my Sur Ron, I’d be going nuts during COVID19.

  10. Mark,
    Again Bro, great comments and insights!
    Question, when people talk about their Sur Ron’s I hear the model Light Bee thrown around, I’ve ordered the X Black Edition. Is there a difference between the two?

    1. Hey Shawn sorry I don’t check here often. The Light Bee is the model and the X Black edition is just a different color and fork. Other than that it’s the same.

  11. I’m interested in the Sur Ron offroad as a “farm bike” and also for wild camping – for this I need some sort of load bearing capacity to carry stuff for my livestock, and camping gear – so I will need a pannier rack – does sur ron make one to fit their bike, or will another make do ? , does it need any adaptions ?
    many thanks

    1. Hi Anthony, I have seen quite a few people use the SR as hauling vehicle. As a matter of fact the USN SEALS have purchased a few to test out in the field along with the British SAS. To my knowledge SR does NOT produce panniers. I have seen some farm folks extend the rear by using the sub frame spars and u channel aluminum to make a rack.

  12. hi. I just had a quick question. Can the Thule bike rack mentioned hold 2 Surrons at the same time?

  13. I wanted to stop by and say that after 28 months of ownership and 5220 miles I’ve experienced ZERO problems of any kind with the bike. Sure I’ve had to change tires, replace the chain and brake pads, but those items are to be expected. Lightweight EVs are remarkable, so much so that I also opted to purchase a Cake Kalk& which is completely homologated for US streets. A completely different bike than my beloved SR, but wonderful in many different ways.

  14. Hi, just came across your build. Wanted to say thank you for such an in depth and thorough review of the sur ron. The bikes been out for a while now but theres still not a whole lot information on it still for modifications. This site has been so helpful! I was wondering if you can help me with something. I just bought used ohlins ttx22m 9.5”x3.0”. I plan on changing out the spring rate thats on the shock for something heavier but I was wondering if this shock would fit on our sur ron and what else do I need in order to install them. I tried searching online but there aren’t too many people thats installed ohlins on a sur ron. Any help would be greatly appreciated. Thank you!

    1. Hey Marvin, so sorry I’m just responding. I don’t come here often. I had a metal fabricator make me a 1″ extension for my 9.5 TTX Ohlins. Mine has the 502lbs spring which is just right for my weight and riding style. I’d recommend finding a metal fabricator in your area and having them make you one. I ‘heard’ that TTX 10.5″ Ohlins don’t have springs that are stronger than 400 pounds.

  15. Very helpful, thank you

    “You can find the bike’s stats, measurements, etc. anywhere on the web.”

    Yes, but stats are also a “Bill of Materials” on a particular reviewed bike that provide a baseline as the model changes.

    For example, I am trying to judge how your mileage numbers relate to the current edition.

    Linkage bearings: ICE trail riders service and replace their bearings, even sealed ones, at very short intervals. It’s just part of the ride.

  16. Dear Mark,

    Thank you for the detailed information. Much appreciated.

    Two things. One, as previoulsy mentioned, the link to the website seems not to be working.

    Two, in your opinion, for my 10 year and 8 year old, should I go for the Youth versions, or simpy go for the ‘grown up’ one right away?

    Your assistance is highly appreciated and I am looking forward to hearing from you.

    Kind regards


    1. Phil because kids grow (I have two adult kids and for some reason they grew taller than me!) I’d get the non youth versions. Just like shoes if you get them their current size in 6 months poor dad will be buying new ones. Just my view.

  17. Hey Mark,

    Superb review in every way, just what I needed for my decision to finally get one.

    However, I’m currently around 230 lbs (damn these strong bones). That’s a bit over the maximum load. I would only ride it on streets and relaxed gravel roads, would that be okay? I saw that 550 lbs spring update, which could fix the issue, but it seems very hard to come by.

    Thanks man!

    1. Mirko you’re not too heavy. I’m not sure if you are referring to and Fast Ace or DNM shock. Mine was the Fast Ace, but I switch to an Ohlins TTX. I’d search Pink Bike to see if you can get a stronger spring for what you have. Also check sites that make things for mopeds they are a good resource.

  18. Great article. I’m fascinated by this ‘class’ of eBike/Motorcycle and this long-term review is excellent. It’s really too bad that finding articles by knowledgeable owners that can articulate the whys and wherefores is so rare. Thank you.
