Complete Stealth Bomber ebike build from scratch to test ride! A lot of this video is wiring, which, if you're building an ebike is what you're going to spend most of your time doing. I show how to set up a wiring panel that includes a bunch of components like the contactor, fuse box, ignition relay, and others that are often skipped on an ebike, mostly due to lack of space. I also show how to wire your switches and accessories in a way that's easy to service and assemble. Once the bike is assembled, I take it on the road and test all the different riding modes, acceleration, top speed, and regen braking.

This is a pretty long video so be sure to use the chapter to jump through the different sections!
