Interesting idea... but the price gives me pause unless you have a uber nice bike to convert.

The recently announced Bimotal Elevate, which is intended mostly for mountain bike conversions, takes a new approach to DIY electric bicycle conversion projects. Unlike most kits that use a hub motor wheel in place of the existing bike wheel, the Bimotal Elevate kit leaves your existing bike wheels in place. Instead of a hub motor, it adds a cleverly designed motor unit to the disc brake mount. I know that sounds strange, especially considering that brakes are normally known more for their stopping power than their propulsion.
The kit includes a large gear that is mounted directly to the disc brake rotor on either the front or rear wheel of the bike. That rotor and gear combo replaces your existing brake rotor on your wheel. The motor unit is then mounted to the frame or fork using the disc brake’s caliper mounts. That allows a drive gear on the motor to spin the wheel-mounted gear, propelling the bike. The unit isn’t compatible with all bikes, but should fit those with external disc brake mounts and ISO/post mounts. The San Francisco-based startup Bimotal has a page on their site with compatibility info, if you want to verify whether or not it will fit your bike.
And with 50Nm of nominal torque and 100Nm of peak torque, the drive should be plenty punchy. It will even power riders up to 28 mph (45 km/h). Not too shabby. Don’t expect this to be one of the more affordably priced e-bike conversion kits, though. Innovation isn’t cheap, and neither is the Bimotal Elevate kit. It’s priced at $1,950, though you can put down just $100 to reserve a kit ahead of deliveries next year.
Interesting new electric bicycle conversion kit adds 750W via your disc brake mount
I’ve always been a fan of electric bicycle conversion kits that combine my passion for electric bicycles with my love...
