1) Using your hand squeeze the top of the caliper arms until the brake pads lightly touch the rim.
2) While continuing to squeeze the caliper arms use your other hand and the 5mm allen wrench. Tighten
the anchor bolt securely. Once the anchor bolt is tight, you can release the caliper arms.
3) Pull the brake lever in and hold it while trying to push the bike. If you are unable to move the bike easily
then the brakes are set correctly. If you are able to push the bike then you will need to do further
adjustments.
Refer to the below steps if you require further adjustments
1) Loosen the lock nut on the brake lever by turning it to the left (counter clockwise), Loosen the bezel by
turning it to the left (counter clockwise) by two complete turns, and tighten the locking nut by turning it
to the right (clockwise).
2) Test the brakes to see if they hold, if they do then you are finished, if the brakes do not hold and the bike
still moves freely repeat step 1.
3) After you are satisfied with the brakes pull the brake lever in all the way ten times to make sure the
cable is not going slip.
Squeeze from each side in this
direction.

thumb nut (located on the opposite side of the lever) and
turn the cam lever clockwise two turns to tighten. Folding
the cam lock lever down will compress (clamp) the
opening for the seat post.

axle. CAUTION: BE CAREFUL WHEN THREADING PEDALS ONTO CRANK ARMS. DO NOT
FORCE!!! PEDALS THREAD EASILY WHEN INSTALLED PROPERLY.
b) Finger thread right pedal marked “R” on pedal axle clockwise (towards the front of the tryke) into right
crank arm. Right crank arm is on the side of tryke with the chain guard.
c) Finger thread left pedal marked “L” on pedal axle counterclockwise (towards the front of the tryke) into
