Motor Cabinet Jig (Dolphin)

Often referred to as a “dolphin,” this USA-made motor cabinet jig is crafted from 4130 chromoly steel, making e-bike assembly a breeze.

This jig simplifies the process of locating the motor cabinet on your frame with precision—no fabrication needed. If you’re building a bike that uses a Bosch Gen 5 drive unit, this tool is a must-have for a smooth and accurate setup!
