2021 Zero FX: Trail-Shredding EV Power in a Lightweight Package

Out of the five dual-sport motorcycles Zero has in their new 2021 lineup, the 2021 Zero FX can be found at the bottom of the performance and pricing scale, but don’t let that fool you into thinking this machine is a dud; it’s quite literally insane.

The Zero FX is much like it’s street-oriented FXS brother and contains most of the features/specifications but is born from a dirtier pedigree and is your best bet when seeking an extremely lightweight bike for trail-blazing.

When I say lightweight, I really mean it. Although this model comes in 2 separate configurations (the ZF 3.6 kWh model, and the ZF 7.2 kWh model), if you decide on taking the 3.6 kWh battery configuration just know you will be truly riding the lightning with 78 lb-ft of torque being produced by a staggeringly light 247 lb (112kg) bike. For the sake of perspective, a petrol-powered Yamaha MT-09 street bike (crowned the king of torque wheelies) produces 65 lb-ft of torque from a 414.4 lb (188 kg) motorcycle. The torque/weight ratio on the Zero FX is unparalleled and can only be experienced on an EV platform, most notably any of the American-made Zero motorcycles.

Having to switch through gears to find adequate power when out on the trails (and perhaps stuck in the mud) is burdensome, but with a direct drive motor like the Zero FX has, that problem is quickly remedied with unlimited power at any rpm. How? This bike only has one gear. Fast.

The 2021 Zero DSR/BF starts at $9295 USD / $12,363 CAD

2021 Zero FX Features

Tuned in to your ride

Crossing from smooth asphalt to loose gravel fire roads? All good. Change performance profiles at the press of a button to master any terrain. The Zero FX is pre-programmed with Eco or Sport modes and performance can be fully customized using the Zero Motorcycles app where you can also see detailed ride stats.

Charge. Simply.

Wake up, ready to ride, with a “full tank” every day. No expensive charge station required. A simple 110 V household outlet satisfies all the needs of the Zero FX’s 650-watt onboard charger. Every outlet is now a “fueling” station.

Crave faster refills? Pick up an accessory Quick Charger to cut charge times by over 60%.

Your Low Maintenance Ride

Built for riding adventures and carefree living. Forget about messy oil changes, dust-clogged filters, fouled spark plugs, time-wasting tune-ups and greasy chain maintenance. The Zero FX’s motor is sealed. It has a single moving part that efficiently relays your throttle hand’s desires to your rear wheel via super-efficient carbon fiber belt-drive system. Ride more, easier. The Zero FX’s advanced battery features life-of-motorcycle cell technology that’s covered by a five-year, unlimited mileage warranty.

Instant “full tank”

There’s no faster way to “charge” than throwing in a fresh battery. The Zero FX’s optional hot-swappable batteries allow you to go from empty to full in seconds. Easily recharge drained modules using off-board charging accessories for a never-ending ride.

Stretch your endurance

Cruise through city streets. Or, hit the dirt. Push yourself and ride until your muscles throb or your legs give out. Most Zero FX riders find they’ve hit their endurance limits long before their battery. Continual improvements to the Z-Force® powertrain have imbued the Zero FX with the highest power and energy density battery in the industry. The Zero FX produces an impressive 91 miles of “city” riding on a single charge.
