AMX Controller Replacement

This is a guide on how to replace your AMX Controller. Do not attempt this unless you've been advised to from Analog Motion.

This is a rather long operation, we recommend to find a well lit space and maybe make yourself a cup of tea or coffee. Before attempting, please email to diagnose your issue.
Tools needed

- 2.5mm Hex Key

- 4mm Hex Key

- A bike wheel spoke (or a tiny hook, of you don't have any you can modified a coat hanger to make one, see picture below)

Before you start

If you don't have a bike stand you might want to place your bike upside down so it's much easier to work on. If you do so, make sure you rotate the display inward so you won't damage it.

Use a 2.5mm Hex Key to loosen the display clamp.

Then simply rotate it so it won't touch the ground when you place your bike upside down.

1. Getting all the cables out

The first step is to get all the cables out.

Start by disconnecting the motor cable

Using the spoke, start gently pulling out the cables one by one.

Here is the list of cables:

  • Rear brake cable
  • Motor cable
  • Pedal sensor cable (flat cable)
  • Rear light cable (the one with a spiral cable) and front light cable, which are both connected to the Light Controller
  • Controller loom

Once you got everything out you can disconnect the controller loom connector, the pedal sensor cable and the light controller connector.

2. Remove the AMX Controller

Remove the battery.

Unscrew the two controller bolts with the 4mm hex key.

Gently pull out the controller upward, the rubber grommet will likely come out with the cable (it's ok you can place it back later).

You can then replace the controller, make sure you slide the grommet over the cables before you start threading them down the hole. Slide down the cables gently one by one, see picture below for cable identification.

Reconnect everything (you can just tuck in the accessory cable as it is not used on the AMX yet), test if it is working by inserting the battery and connecting the display. Then move onto the next step.

3. Tidy up

Gently tuck all the cables back inside the frame, start with the big ones (Controller, Light Controller, then Pedal Sensor cable, Motor and Rear Brake cable should go last.

See the picture below to see how it should looks like

Once you've put everything back in place you can re-connect your motor cable, make sure the arrows aligns and that the cable goes all the way to the line.

You're all done!
