 WARNING: 
The brake is capable of 
causing the electric motorbike 
to skid the tire throwing an 
unsuspecting rider. Practice 
in an open area free from 
obstacles until you are familiar 
with the brake function. Avoid 
skidding to a stop as this can 
cause you to lose control or 
damage the rear tire.

 REPAIR AND MAINTENANCE 
Check the Razor website for any updates on the latest repair and maintenance procedures.
2 If the brake has too much 
slack, loosen the rear anchor 
bolt with a 5mm Allen wrench 
and pull the brake wire tighter. 
The distance of the brake wire 
between the end of the cable 
and the anchor bolt should be 
between 37mm and 44mm.
3  If the brake rotor is 
dragging on the brake pads, 
use your fingers to twist the 
caliper adjuster in either 
direction until rotor is cen-
tered between pads.
1 To adjust the tension, thread 
the brake lever adjuster in or 
out 1/4 to 1/2 turn until the 
desired brake adjustment is 
attained. Most adjustments are 
complete at this step. If brake 
still needs further adjustment, 
proceed to step 2 for rear brake.
BEFORE RIDING
Turn power switch “OFF” before conducting any maintenance procedures.

Charging the Battery 
Your electric motorbike may not have a fully charged battery; therefore it is a good idea to charge the 
battery prior to use. 
2 Turn OFF power switch 
before charging. Plug charger 
into the charger port on the 
electric motor bike.
1 Plug the charger plug into a 
wall outlet. If the lights on the 
charger do not light up, check 
the power to the outlet. If nec-
essary, try a different outlet.
 WARNING: 
Always disconnect your electric 
motorbike from the charger before 
cleaning with liquid.
Note: If your charger does not 
look like the one illustrated, 
your unit has been supplied 
with an alternative charger. 
The specifications and charging 
procedure would not change.
The charger has a small window 
with one LED to indicate the 
charge status. Refer to the 
illustration on the charger unit 
for the actual “charging” and 
“charged” status indications for 
your model charger. 
Chargers have built-in over-charge 
protection to prevent battery from 
being over-charged. 
Charger will get warm during use. 
This is normal for some chargers 
and is no cause for concern. If 
your charger does not get warm 
during use, it does not mean that 
it is not working properly. 
Be sure to properly align the 
groove on the charger input 
plug with the corresponding 
socket on the case; otherwise, 
no charging action will occur.

q Testing the Brakes 
To use the brakes, squeeze the levers to increase the pressure on the brake. The brake levers are fitted 
with a cable adjuster to compensate for cable stretch and/or to fine-tune the lever movement to brake 
engagement. If brakes are not engaging properly, follow instructions for adjusting the brakes outlined below.
