■Check before riding
4. Brake inspection: Brake system includes brake handle, clamp set, brake cable and
so on.
[ ]Clearance between brake block and wheel rim inspection: The distance between
brake block and wheel rim should be between -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.
5. Shift Grip: Style of speed changing handle bar: Rotary (Grip Shift) 7 speeds
6. Throttle
7. Other attachment: Reflectors
Rotate the (left) grip of throttle downward to
make bike go forward and loose the grip to slow
down the bike. If your loose the grip completely,
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.
