1. Operate the shift lever to shift the chain from top gear to 2nd gear.
• If the chain will not move to the 2nd gear, turn the cable adjusting barrel on
the rear derailleur to increase the tension (counterclockwise)
• If the chain moves past the 2nd gear, decrease the tension (clockwise)
2. Next, with the chain on the 2nd gear, increase the inner cable tension while
turning the crank forward. Stop turning the cable adjusting barrel just before
the chain makes noise against the 3rd gear. This completes the adjustment.
Make sure the drivetrain is clean. We suggest "dry" lubricants for most
applications.
Step 8: Check Before Riding
Make sure the wheels are tight and secure. Tighten the front and rear hubs nuts
securely. (Tighten torque: about 30N.m for front wheel, about 25 to 30 Nm. for
rear wheel).
For Quick-Release (QR) hubs/axles, make sure the QR levers are in the locked/
closed position. Before riding, lift the front of the bicycle so that the front wheel
is off the ground, lightly bounce it to the ground and give the top of the tire a few
downward strikes. The wheel should not wobble or come off and there should be
no rattling. Do the same for the rear wheel.

How start aid works: When pressing the Start Aid button, the bike can be started
at a speed of ~3.5MPH (6km/h). When the bike starts moving forward, start to
