e-bike throttle modification kit
These files should help you modify your twist throttle to thumb style. My motivation was to convert it so I can use classic bicycle grips on my folding e-bike without need to spend money on different throttle and time on rewiring.
Tested on Engwe T14 folding ebike.
Prep-work
- strip your twist throttle and verify it has 12 rivets and diameter of 30mm (my throttle had slight conical shape, so use caliper)
- cut twist throttle roughly to be 8-10mm long
At this moment, throttle is free and spring can push it off, so be careful!
Printing
Model is created with no printer tolerance in mind. So if your printer is not tuned up properly, you will probably have to experiment with print settings to compensate for wall thickness.
Printed with PET-G to ensure UV light resistance and some flex to the parts.
Assembly
- Just push thumb lever in place. You have 12 rotation options so use it to tune your preferred location of lever.
- Mount throttle on handlebar and slide stop ring.
- Slide in your shiny new grip and fix throttle against the grip. Stop ring will ensure throttle can spin and will not be held by rubber grip.
- In case you forgot your stop ring (as well as I did), use stop ring v2
- Ensure thumb lever spins freely and reverses to original position with no problem and modify accordingly.
- Enjoy!
Disclaimer:
Even though I am willing to help you troubleshoot, I am unable to verify every single twist throttle will fit. So remember to measure twice, cut once!
The model on my photo is modified by hand because I did have first measurements slightly wrong and it was too late when I noticed. Uploaded models are updated to fit better.
Feel free to ask questions and share your experience so I can update files accordingly :)
