If you think your controller isn’t working, please follow these steps before getting in touch with us:
1) Check whether the display turns on
Hopefully you are using one of our compatible displays with the controller. If not that is probably why it’s not working and you should purchase one.
If the display turns on, then this is a good start and means that the controller probably is in working condition but that something else is wrong.
If the display isn’t turning on, then check that the battery is correctly connected (test the voltage at the controller input) and that the display wires are connected properly.
2) Check motor connections
A common problem is that the motor connections haven’t been pushed in fully. Please check that they are fully connected.
3) Test in the 6 km/h mode.
To see if the controller is activating correctly, activate the 6 km/h mode by holding the button for 5 seconds on the LED display or going to the relevant setting on the LCD display.
You should see the motor activate and turn. If not, check for voltages coming out of the motor phase wires.

4) Check acceleration signals
So far so good. If all that is working then the problem is with the activation signal to the controller coming from the throttle or the pedal assist sensor
If you are using one of our throttles or PAS then this should work OK, please check the wires are connected OK, turn the throttle or activate the PAS (the red light should blink) and hopefully you’ll get some joy. Please try both the throttle and PAS.
If that doesn’t work then you can request a replacement throttle/PAS from us.
If you are using a throttle/PAS from another supplier, then this is probably the issue. Check the wiring diagrams on our product pages and ensure that the wires are connected OK.
On the throttle, you should have red = +ve power, black = -ve power, and then the third wire is the signal (usually blue or white coloured)
so ensure you have connected red-red, black-black and blue/white-blue/white.
Similarly on the PAS, usually you have the same colour coding as for the throttle above, or:
brown = +ve, black = -ve and yellow = signal
