Summary: The Smart Chock is a motorcycle front wheel stand with a wheel
cradle designed to automatically adjust within a specific
width range to hold the front
The Smart Chock motorcycle front wheel stand has an interesting feature: a
holder cradle, which consists of two metal halves with interlocking
As the motorcycle is pushed into the stand,
rotates forward, and a cam on the cross bar
squeezes the two sections of the cradle together, which
theoretically helps to secure the tire.
The company’s marketing material states that the
device is "engineered to ‘intelligently’ grip and
release your tire". They also say that "the big advantage of this design is
that you can use one Smart Chock for many different
bikes with different tires.”
This sounds good in theory, and the Smart Chock is an
acceptable front wheel stand, but we're not sure if
there's an overwhelming advantage to this design, at
least for the motorcycles we used for our evaluation.
We compared the Smart Chock to the Acebikes Steady Stand
reviewed, which doesn't have an adjustable cradle
but, still manages to hold different tire widths and
diameters just as securely, if not more so, than the
Smart Chock, in our opinion.
motorcycle rolls up and on to the cradle of the Acebikes Steady
Stand with less
effort than it takes to push the bike into the Smart
Chock. We think part of the reason for the greater
effort required for the Smart Chock is that the cross
bar is approximately 1-1/2" in diameter, compared to about
3/4" diameter on the Acebikes Steady Stand.
We presume that the larger
diameter cross bar on the Smart Chock is
necessary to provide a larger bearing surface for the
But the larger diameter means that the wheel cradle
on the Smart Chock is about twice as high as the cradle
on the Steady Stand, which sits only about 3/4" from the
So it takes more effort
and energy to get the motorcycle wheel up and over the
added height of the Smart Chock.
Also, the smaller diameter cross bar on the Acebikes Steady Stand is
located through the center of the stamped metal wheel cradle,
inside the apex. The tire rolls right over this
cross bar with little effort; the tire barely touches
the cross bar because the diameter of
the tire is much greater than the angle of the cradle;
thus, the cross bar offers almost no resistance to the tire as the bike is pushed forward into the
In comparison, the cross bar on the Smart Chock is
located underneath the apex of the cradle, and this
design locates the bottom of the cradle at nearly twice the height of the Steady
The taller height of the Smart Chock cradle means
that an increased effort is required to push the bike up on to the cradle.
This in and of itself wouldn't be that much of an issue, but the extra effort seems to
sometimes overwhelm the grip on our garage floor that is provided
by the rubber end caps on the Smart Chock.
The end caps are
designed to keep the stand in place to prevent it
from slipping forward as the motorcycle is pushed in. The four rubber end caps are round, and
it's possible that they don’t provide the surface area
required to grip well enough to hold the Smart Chock steady
on our garage floor.
combination of the extra effort needed to get the bike
up and over the height of the wheel cradle can
sometimes overcome the friction of the end caps, and as
the bike is pushed in, the
Smart Chock sometimes slides forward instead of staying
The manufacturer does warn that the Smart Chock
shouldn't be used on a slippery surface, and we don't
think our concrete garage floor is slippery. Obviously, each surface will
offer a different amount of grip, but we haven't
experienced a slippage problem with the Steady Stand or
any other type of stand on this floor.
It's possible that the friction of the end caps on
the Smart Chock could be increased if the
surface area where the rubber meets the floor was
increased. This might be done
by either using longer length bumpers, or by using
rubber bumpers with a square profile so the flats would
lie on the floor, or perhaps by using rubber with a grippier texture.
Although the rubber ends on the Acebikes Steady Stand have a
smaller diameter, they are longer than the grips on the
Smart Chock, and the rubber seems to feel "stickier",
which we think improves the grip and helps to prevent
the Acebikes Steady Stand from moving as far when the bike is pushed in.

the Steady Stand (right) is located through the apex of

The split wheel cradle on the Smart Chock has fingers
that must be positioned so the two halves can move
as the cam pushes the two halves together. The orientation of the fingers is
important to the functioning of the cradle, but we don't
think this point is described very well in the
instructions; indeed -- overall, our feeling is that the
instructions are less clear than they could be.
We think the instructions could be improved by
providing information like a
detailed parts list, a description and photos of what
bolts should be used in which
holes, and a narrative description of how to assemble the
pieces. We also think real photos of the product
in the different stages of
assembly would help to make the instructions more clear,
rather than the computer generated graphics that are
printed on our instruction page.
Our kit did not include
washers for the Nylock nuts that secure the ½” stainless
steel bolts that hold the cradle assembly, although this
may have been an oversight in our kit only, so we
We think another important piece of information
should be added to the instructions regarding the
positioning of the cross bar. This would help with
both the assembly of the stand and the understanding of
how it works.
The cross bar has width adjustment holes
for the cams, and these
holes are used to change the location of the cams to adjust
for different sized tires. We think the
provide some guidance to indicate which holes to use
for different tire widths. It would seem useful to
offer some guidance on the settings, rather than
requiring the customer to use trial and error.
For example, motorcycle front tires only come in
about four different width ranges. I'd guess that
the ranges encompass something like 90 to 100
mm; 100 to 120 mm; 120 to 130 mm and maybe 130 to 150 mm
wide. So it would be nice to have markings or some
indication as to which width settings on the cross bar
might be a good starting point for each of those ranges.
The manufacturer suggested we start with the
narrowest width setting for the adjustable cradle. This
was just big enough to fit the 120/60-17 front tire on
the Multistrada, but we discovered that it seemed too narrow to fit the 120/70-17
front tire on the GT1000 for some reason.
Possibly the taller profile of the 70-series tire, or
the different profile of the Michelin vs. the Pirelli,
causes some interference between the tire and the
cradle, but it's curious that the cradle wouldn't
accommodate this small difference; this tells us that the
adjustment width of the cradle is critical.
We then re-adjusted the cradle width to the next widest
setting, but this seemed to be slightly too wide for the
120-series tires on both bikes. It works, but the
cam doesn't seem to hold the cradle tight enough and the bikes
seem less stable in the Smart Chock than when they are
being held by the Steady Stand with its single piece
cradle. There's movement in the
two halves of the cradle if the bike is rocked back and
forth (see the video above).
The Smart Chock also has two adjustment locations for
the fore/aft position of the cross bar on the frame of
the stand, which allows adjustment for different wheel diameters.
There was no guidance in the instructions to tell us which holes correspond to which tire diameters,
guessed that the hole towards the front of the stand would work with 17”
diameter Sportbike tires, and we were right.
After we finally got everything assembled and
determined an optimal setting for the 120-series wide
tires on both Ducatis, the Smart Chock is capable of
holding the motorcycles. However, our
experience has been that the adjustable front wheel
cradle doesn't provide us an advantage over the simpler
design of the Acebikes Steady Stand.
The Smart Chock is an interesting concept, but we're not
sure if the design provides an overwhelming advantage.
Our experience indicates that the width adjustments of the Smart Chock's cradle seem
to be critical to the function of the stand; its cross bar
raises the wheel cradle higher, requiring more effort to
get the bike into the stand; and the round rubber caps
don’t always provide enough friction to hold the stand
when the bike is pushed in.
The Smart Chock does offer an acceptable level of
performance as a front wheel stand,
but in our situation, with the motorcycles we used, our
opinion is that it doesn't offer the advantage that we

From "J.H.": "I am a trailer dealer in Vancouver British
Trailers Ltd). I wanted a free standing wheel chock to place in my
trailers for the motorcycle customer that needs haul their bikes. I
have been using the Smart Chock for about 8 months now in both my rental and
sold trailers. The customers have been really happy with them.
I did not originally expect to sell them with-out the
trailers but this is what has happened. Word of mouth and the internet
has got people calling wanting to buy just the chocks.
With the adjustable wheel sizes it is perfect for rental
trailers. Many that rent the trailer have bought the chocks.
It seems that you had some trouble with setting up the wheel
width and skidding the chock on the floor.
You are right that the chock tire size adjustment is
critical to the proper performance of the chock. I show the rental
customers how to use it and they have not had any problem getting the right
size. For the other customers they only have to set it up once for
their bike and they are done.
I don't know about the skidding because my chocks are
secured to the trailers, but I have not heard that it is a problem.
I just thought you might be interested to get some feedback
from customers that actually use the chock. My opinion is that it is a
really good quality product and built to last.
I have never seen the chock you compare the Smart Chock to
so I can't comment on it's pros and cons. Just thought I would let you
know that this chock has done the job I purchased it for. I appreciate
your sharing of information about bike products and enjoy visiting your
