IMPORTANT NOTES
● Read this instruction manual carefully and keep them for future reference.
● This product requires assembly. Mind each caution below.
● This product is made to be assembled one way only. Any modication or change from the
supplied instructions will void the warranty.
● A 1-year warranty is provided for this product. Please refer to the enclosed warranty card
for more details.
For standard 2-wheel bicycle with a wheelbase between 950 and 1,090mm only. No other bikes (including
small wheel bikes and BMX) can be used on this product.
We don't recommend using this product with a recumbent bike because its riding position is so special that it's
hard to keep correct balance. If you use a recumbent, you do so at your own risk.
It's dangerous to remove your hands from handlebar while riding on rollers. Place your both hands on the
handlebar gently (do not grab hard) at all times. Do not look down, and try to look 2 – 3 meters ahead for safe
riding.
Adjust the front roller position properly in the best position for your bike's wheelbase.
If the front roller is located too far forward, the handling performance on the front end will be unstable and you may
fall easily. If the bike is too far back, stability will decrease.
Make sure you are positioned several inches off the oor. Being on rollers mean you won't be able to reach the
oor in the same way as if you aren't on rollers. While supporting yourself, nd the best place to put your foot down
when needed. If you have cleats on your shoes, be extra careful not to slip on the frame or the oor. An optional
foot step is available for added safety.
It's dangerous to touch the spinning roller or belt. Keep small children and pets away from the rollers while workout.
Keep any sharp and fragile items away from the rollers to prevent any unexpected accident.
Before each use, make sure all bolts and nuts are properly tightened.
Do not adjust the bolts on the end of the rollers. This could cause serious damage to the rollers.
Do not over tighten the Dome Nut. This will cause the inside metal collar to deform, and ruin the at washer which
could result in serious injury.
Set the Roller Belt properly on the grooves found on the roller drum end caps. You cannot ride on rollers without
this belt. Check the belt before every use. If the belt becomes worn or frayed, replace it immediately.
Be careful not to pinch your nger when folding down the frame. Do not stand on the roller drums.
Rollers do not offer any support. You must learn to keep your balance while on the rollers. Place the rollers on a
at surface and near a hand rail or something you can hold onto until you can gain your balance on the rollers.
If you don't install the optional Mag resistance unit on the frame, remove the mag unit V-belt to avoid any risk of an
accident.
Set the air pressure 10% higher than usual. If it's too low, squealing will occur.
If the tire is wet, it will slip and that is dangerous. Always wipe any moisture away before use.

!
!Do NOT use brakes when on the rollers. This could cause serious injury.
To stop, simply stop pedaling and wait for the bike to stop rolling.
The belt will stretch over time. To help keeping its shape, we recommend folding the rollers down when not in use.
The belt is made of urethane material. It should be exible enough but it could get longer and may not t your roller
position setting. Replace the belt if it becomes too long.
About Foot Adjuster
The foot adjuster works to change the height and angle of the rollers. If each drum is not parallel when you
place the rollers on the oor, extend the adjusters to to make each roller level. Make sure to tighten the lock
nut when done adjusting.
!
About Bridge Frame
If the Roller Belt has scratched the Bridge Frame while running, it will be worn out so quickly. Make sure you
put the Bridge Frame into the belt loop when assembling.
!
When Installing Front Guard
The Front Guard is installed between the front roller and the frame. Remove the inside washer that sits
between roller drum and frame. You will use the Front Guard itself as a spacer.
!
About Anti-Slip Rubber
Put the supplied rubber sheet on top of the Mid Frame on the side you usually place your leg to support yourself.
When using the optional Foot Step at all times, you should put it on opposite side.
About The Hole for 24" Wheel
There are two holes on the Rear Frame for the Rear Roller. The rear hole is for the standard 700c / 27" wheels,
and the front hole is for smaller 24" / 650c wheels. You set the rear roller in the front hole when you use MoZ-
Roller with smaller wheel bike.
This hole also can be used for micro-adjusting the wheelbase size setting. The hole pitch is 40mm. It means the
rear wheel can be set 20mm ahead (a half of hole pitch) when you use the front hole.
For example, if your bike's wheelbase is 980mm and you set the Front Roller at the "970" position, it's too short
and may become unstable, but the "1000" position is too far.
In this case, you should set the Front Roller at "1000" position hole and use the front hole for the Rear Roller.
It enables to get the best size for 980mm (1000 - 20 = 980).

These instructions are based on NOT using the the Front Guard. If you plan on installing the Front
Guard, refer to this section on page 8 of these instructions.
There is a metal bracket in the Front Frame which holds the Bridge Frame in position that
connects both frame sides. This bracket won't move while xed with bolts, but it will move freely
in the frame tubing once the bolts are released.
When you install the front roller, make sure to place this bracket towards the center frame before
assembling. Failure to do so might cause an issue where the bracket comes off over the front
roller axle making it impossible to install the Bridge Frame.
How To Assemble MoZ-Roller
Take out the Frames from the package, then distinguish the direction.
The right side frame has the Lock Release Lever to prevent unexpected folding, but any other points are same on both
sides. (Fig.A)
[Left Side Frame] [Right Side Frame]
There is no specific direction on the roller drum. It's symmetric. All three rollers are exactly the same.
Put a Flat Washer to the left side axle to protecting the bearing, then insert to the smaller hole on the left side frame.
(Fig. B)
Insert the Metal Collar, Flat Washer and Spring Washer from outside of the frame, then loosely screw on the Dome Nut.
Repeat this step for the remaining rollers. (Fig. B)
Required Tools: 17mm Spanner (x 2), #2 Phillips Screwdriver or 10mm Socket Wrench
(Fig. A)
Lock Lever is located on
the right side frame only
(Fig. B)
The left side hole is always larger diameter than the right side one.

4Put the Roller Belt on the Front and Mid Rollers. You don't put the belt on the Rear Roller. (Fig. C)
Put a Flat Washer and Metal Collar in the axle, and insert the right side frame to all axles. After installation, put a Flat
Washer, Spring Washer and Dome Nut, then tighten temporarily.

Metal Collar Insertion Direction
The right and left frames are exactly the same, except the
Lock Release Lever. It means the hole size combination is
same between the right and left frames; The left side hole
is larger, and the right side hole is smaller.
The Metal Collar must be inserted from the larger left side

If you will install the optional Mag Unit to increase the resistance power, put the V-belt on the Rear
Roller. The belt comes with the Mag unit. (Fig. E)
If you will not use the Mag Unit, even temporarily, it is strongly recommended you remove this belt
to prevent jamming of the rollers.
During this step, shape the frame into a "Z". This will make the belt installation easier. (Fig. D)

If you don't use the collar, the frame will deform due to the torque of the Dome Nut. If this happens,
the frame cannot be repaired.

5Install the Bridge Frame under the Front Frames. (Fig. F)
If you cannot screw the bolt to the thread hole on the inside braket, check that if the bracket is
located in the correct position. It may be caught by the Front Roller axle in the frame.
To solve the problem, remove the Front Roller, change the bracket position, and install the roller
again.
!First, make sure the Bridge Frame comes through the roller belt loop. If you don't make sure, the
belt will be in contact with the frame at all times causing premature wear and failure of the belt.

When you install the bracket for the optional Mag unit on the Rear Roller, you may need to remove
the Flat Washer and keep the Spring Washer only to tighten the Dome Nut due to the limited axle
length. (Fig. S)
Keep the recommended tightening torque: 8 N.m.
If the Dome nut is overtightened, the alloy metal collar will deform and will be impossible to pull
out. Or could cause the at washer to form sharp edges that could cause injury.
!
A Phillips head screwdriver can work, but we recommend using a 10mm socket wrench.
(Fig. F)
(Fig. G)
The nut on the roller end cap is precisely adjusted to hold the bearing at proper position.
Except in the case you nd the nut has been clearly loosened, do not try to loosen or over-tighten
this nut.

1While bending the frame in Z-style, apply the Roller Belt to
both Front and Mid Rollers.
The belt must be hooked in the groove on the roller end cap.
(Fig. H)
3Lay down on the floor gently. (Fig. J)
Now the Roller Belt is properly tensioned and ready to ride.
To fold down the frame, pull the Lock Release Lever then push the Front Frame downward.
!Pushing down on the frame without releasing the Lock Lever Release will damage the frame.

Opening/Closing The Frame
How To Open
On MoZ-Roller, the roller drum has the belt groove on
both sides.. Use the opposite side of the Foot Step to
avoid jamming issues.
2Extend the Front Frame until you hear the Locking Lever click
into the locked position. (Fig. I)
Extend the left side frame as well as the right side frame.

If the Roller Belt has come out from the grooves on the
roller end cap, push the belt toward the groove while
rotating the drums slowly.
How To Fold Down
While storing, tie the Roller Belt or hook to the Foot Adjusters, do not leave it hanging loosely.

About Front Roller Position
The Front Roller is adjustable in 5 positions in order to fit your bike's wheelbase
size as closely as possible.
The ruler on the right side frame shows the exact number of wheelbase size,
not the calculated number to expect stability. If you already know your bike's
wheelbase size, set the Front Roller at the next hole of your number. Do not
use the smaller number hole for your safety.
To make your ride safe, we recommend you to set the Front Roller at 10 – 15
mm forward to the front wheel axle. (Fig. K)
As your skill increases, this number will get smaller, and the final setting is just
the same number of your wheelbase (just beneath the axle).
!
HINT The hole pitch on the Front Frame is 30mm. This sometimes makes the front roller position setting difficult to
adjust within 10 – 15mm as suggested, depending on the actual wheelbase size.
For example, if your wheelbase is 980mm, the 970mm position is too short and 1,000mm position is 5 – 10mm
further than the suggestion. It's not recommended.
In this case, you should set the Rear Roller to the front hole on the Rear Frame to move the bike itself 20mm (a
half pitch of the holes) forward. At this moment, you can use the 1,000mm position as 980mm size.
This number corresponds
to the wheelbase when
the Rear Roller is set at
the 27"/700c hole.
How To Install Front Guard
The position just beneath the front wheel axle is only for
expert level riders because the handling becomes so quick
(but natural).
On the rollers, the front wheel will move sideways very
quickly once the roller starts spinning.
The Front Guard is a safety device to push
the front wheel back to center if you lose
balance and nearly drop off from the rollers.
Also the speed can be reduced by the friction
created when the front tire and guard come
in contact with each other.
We recommend the Front Guards for the
beginners.
(Remove)

The roller axle length is limited and it may be
too short when installing the Front Guard.
If so you should remove the Flat Washer and
use the guard itself instead of the flat washer.
Face the plastic side toward the tire.
If the front wheel axle is further front than the roller, the
bike will come off the rollers in front very easily.
If positioned too far behind, the bike will feel heavy and
unpredictable.
