How to Install a New Shifter on an eBike

A new shifter install is not something you will do frequently, but may be something that comes up further down the line. Typically, when a new shifter is needed it is due to the ratcheting mechanism inside of it being worn down and not holding properly. But whatever your reason is, this guide will walk through how to install a new one!

Here are the tools needed for this:

  • 5mm Allen Key
  • 4mm Allen Key
  • 3mm Allen Key
  • Phillips Head Screwdriver
  • Cable Cutters

Here is the process:

  1. Before we install the new shifter, we must first get rid of the old cable (a new one will be installed with the new shifter). Go to the derailleur, and loosen the cable clamp with your 5mm allen key. This will free the cable end.
  2. Once the cable is free from the derailleur, cut the old end off so there is just a nice clean cable end (we want to make sure it is a clean cut because if we just pull a old frayed cable through our housing, it will damage the inside and the bike will not shift well).
  3. Once that old cable end was cut off, we can now take the old shifter off. On the right side of the handlebar, use your 5mm allen key to loosen the grip. Once it has been loosened, remove the grip from the handlebar.
  4. With the grip removed, we can now remove the throttle. Use your 3mm allen key to loosen the clamp on the handlebars, and then slide it off. There will be a plastic shim that comes out too. Save that and set it to the side.
  5. After the throttle, use your 4mm allen key to loosen the pinch bolts on the brake lever, and then slide it off of the handlebars.
  6. Finally, you can now remove the old shifter. Use your Phillips screwdriver to loosen the screw underneath the shifter. Once that is loosened, you can slide the old shifter off the handlebar. The cable will still be installed on the old shifter, so pull the cable through the housing to fully remove the shifter.
  7. Next, we will slide the new shifter onto the handlebars and tighten it down.
  8. We then reinstall the brake lever, throttle, and right grip back onto the handlebars and tighten them down.
  9. After everything has been remounted to the handlebars, we will then feed the fresh cable through the existing housing on the bike (the new shifter will have a cable preinstalled in it).
  10. Once the new cable has been fed through the housing, the cable end will be sticking out in excess near the derailleur. While pulling on the cable and making sure it is taut, feed the cable through the derailleur and clamp in the cable clamp.
  11. From here, follow our Shifting Adjustment guide to get the shifting dialed in.

Once the shifting has been adjusted, your new shifter is all ready for the road!
