Electric Bike Thumb Throttle to Twist Throttle converter

thingiverse

I've been experiencing issues with thumb throttles due to repetitive strain injuries, so I decided to create a converter for a twist throttle. This project is inspired by the generic Chinese thumb throttles that come with electric bike conversion kits. The dimensions of this design are tailored to fit snugly over the length of the grips typically provided with these kits, as shown in the accompanying picture. The small end cap for the arms that flank either side of the thumb throttle adds extra stability to this part and can be securely attached using glue; however, it's not strictly necessary, so you can choose to add or remove it according to your needs. Feel free to experiment with and improve upon this design as you see fit – it was created in a relatively short period of time – I hope you find it helpful.
