Ebike Throttle Tube Extender

thingiverse

This extends the stock throttle tube found on many ebike kits to fit a normal-sized dirt bike or motorcycle grip. It will fit on the example throttle pictured above as well as likely any throttle that came with a similar-looking grip design. Just cut off the existing grip and slip this over the end of the throttle tube with super glue between them. These tubes are a little thick for most standard grips but I have found using Goo-Gone Gel as a lubricant allows the grip to easily slip over the tube. Print with the more rounded side down and you shouldn't need supports.
