TROUBLESHOOTING - A Quick Checklist
Here's a quick checklist for fault-finding if you should find yourself at the side of a
road with a problem.
In many cases, reported faults or problems are a simple case of understanding the
product better but unexpected problems can happen.
The following are some simple roadside assist tips for electrical problems:
 No meter power. Check the battery is charging and charged, check the battery
connections, display connections, check the key switch. If none of the above it
may be your control unit or display depending on the model.
 No throttle/pedal assistant power (meter on). This means your battery is
probably fine and it is likely to be a connector .Check the return on your e-brakes,
check connections to your motor, then connections to your interface (throttle)
and sensors. If none of the above it may be the controller failure.
 Power cut-out. Check e-brake return, check battery contacts and if black check
lock in tolerance, check connections. Before seeking help try to notice exactly
when the cut-out occurs, i.e. on a long hill, on a short steep hill, how many miles
from last charge, after a bump, immediately after stopping or slowing. This could
be an issue with the motor.
 Battery not charging. Check the charger fuse, check the power supply. Turn off
other appliances on the same power board, don't use long extension cables.
 Battery cuts out, particularly under load. Check any connectors, check wiring
between battery and motor. This could be an issue with the battery.
 Motor noise. Roll backwards to see if the same noise occurs, cycle without power
to see if the same noise is still there; check connections especially if you have
removed a component recently. Check for sources of friction behind the brake
pads and around the wheel.
 Motor resistance. Ensure motor wheel is mounted correctly, check brakes are
disengaging and set up correctly, check for sources of friction, disengage power
and see if resistance persists, roll the bike backwards with the power on – you
may have a sticky/rusty brake or hub especially if you've driven through flood
water (not advised).
 Short riding distance. This could be an issue with Low tire pressure, Driving on
many hills, headwind, braking, departures, and/or excessive load, Battery
discharged for long period of time ,without regular charges ,aged or damaged.
Fault rates on ebikes are generally very low - about 1% over 12 months -
that's IF they are maintained well, are well built in the first place and are used as they
were intended.
