Working on an e-bike conversion? This mid motor wrench is an absolute essential tool that makes installation and maintenance so much easier! Specifically designed for BBS01, BBS02, and BBSHD mid drive motor kits, this steel wrench has that perfect arc opening that bites tightly to reduce friction and wear while you're working. At 204mm (about 8 inches) long and weighing only 119g, it's substantial enough to provide good leverage but still lightweight and easy to handle. The steel construction is seriously sturdy and thick - this isn't some flimsy tool that's going to bend or break when you need it most. It works perfectly for installing and removing both the inner and outer rings of the motor, making what could be a frustrating job much more straightforward. The package includes everything you need: the wrench tool itself, a winding tube for cable management, and 5 cable ties to keep everything neat and organized. Whether you're a bike mechanic or a DIY enthusiast installing your own conversion kit, having the right specialized tools makes all the difference between a smooth installation and a frustrating struggle. This wrench is one of those tools you might not think you need until you're in the middle of an installation and realize how much easier it makes the process. Definitely worth having in your toolkit if you work on electric bikes!
