Our troubleshooting advice will take you through a logical way to diagnose any
issues that may arise during installation and use.
Before commencing troubleshooting, disconnect all components. Do not short
cut this process. There are countless times a loose plug has caused grief. By
disconnecting all the plugs and then reconnecting just the crucial components, this
will solve any loose plug issue.
Go through one by one by plugging in the other components (such as the pedal
assist sensor or the e-brake handles) to see if any of these are the cause of the
problem. In this basic state you may discover the culprit quickly.
Fault
Solution
Display turns on, but
motor does not
Activate
Check the motor plug from the controller. This is a very stiff
connection and will not work unless the plug is all the way in to
the indicator line. The twisting of the handlebars can sometimes
cause the plug to pull out slightly if there is not enough slack in
the motor cable.
Motor runs backwards
Remove the motor from the frame and switch the direction.
Display won’t turn
on, unless the battery
charger is plugged in
A high pitched rattling
noise can be heard
when accelerating
Rim has a buckle or
spokes coming loose
all the time
Check the display connections, make sure the battery is charged.
If the display turns on only when the battery charger is plugged
in, you will have to contact our support team.
Check where does the noise come from, the motor or the loose
parts. For example a loose spoke or even a bolt on your rear
rack. If something is just a little bit loose, sometimes this can
reverberate and make a harsh high pitch rattling sound. Nothing
is broken or wrong, you just have to identify the loose part!
We would recommend a competent wheel builder to fix any
major spoke tension issues, however there are some really good
youtube tutorials on how to adjust spoke tension.
Spokes have snapped
or missing
We stocks spare spokes for very reasonable prices, just check
out our spares section online and you can find the right type
and length for your kit.
