together during shipping.

main frame of the bike has straightened completely, release the quick release and bring
the lever all the way to the front of the bike. Then, securing the quick release.

4. Unfold the Handle stem (where the handlebar fits into) section of the bike. Then, bring the
quick release over to the top portion of the bike and secure the lever.

suspension under the seat and that the post must be firmly secured before riding the

can be installed by tightening and locking in their respective quick releases.

holder are totally inserted into the battery on the underside. Then, lock in the battery in
place with the key.

the bicycle normally as you would any bicycle.

2a. Power Assist Mode “S” (Standard Mode) –

 Place the key in the lock/switch and turn the key clockwise to the right most position.
 Place the operation switch to the left of the handle bar in “S” position, and then ride

the bicycle normally as you would any bicycle.

 In this mode, the motor will assist you with full power as you pedal the bicycle.
 The motor will stop when you stop peddling in this mode.

 This mode gives you a moderate “miles per charge” and is considered a balanced

mode in terms of energy usage vs. distance.
