■Check before riding

4. Brake inspection: Brake system includes brake handle, clamp set, brake cable and

so on.

[1]Clearance between brake block and wheel rim inspection: The distance between

brake block and wheel rim should be between 1-3mm. When brake block is worn

down, replace it to ensure proper braking. When riding in wet weather stopping

time is increased. Adjust your speed accordingly and allow for additional stopping

distance.

[2]Brake handle grip adjustment: When you stopping brake handle should depress

about half way towards the grip, if brake handle extends closer to the grip, the

space between brake block and wheel rim is too great and should be adjusted

accordingly.

[3]Position of brake handle: Front brake is on the left and rear brake is on the right.

Always brake using the right hand (rear brake) first. Braking with the left (front)

brake can cause the bike to flip and injure the rider.

[4]Brake inner wire: Outlet end of brake inner wire should avoid fork. Cover brake

wire end with an aluminum cap. You should apply lubricant to brake wire

periodically to maintain smooth action and prevent rust.

Do not apply lubricant to brake.

the bike will stop power output. While riding,

accelerate the bike slowly to maintain riding

safety. It's advised that all power supply is shut

down if you stop the bike, to prevent from

operating the throttle improperly and micro

power consumption of battery.
