New electric bicycle conversion kit adds 750W via your disc brake mount

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.

I saw that over the weekend on, and it looks like a nice, but pricey, bit of kit, especially if you wanted to swap between electric and acoustic frequently.

This looks really cool. I agree that it's pretty pricey. But it looks quite nice.

Looking forward to seeing some reviews of it. But I can't see I'd buy it at that price. You could just buy another bike for that much money. If the system works well, I could see myself willing to pay around $1,200 for it, but the current asking price is really high.

I would assume you could use other generic batteries with it. If so, that would be a huge bonus.

Looks like their nitch is ease of installation and removal. The videos they post show ppl riding manually with the kit in a back pack, they come to a long assent and install the kit in a few minuets. Two bikes in one is a tag line.
But for 2k you could buy two plus high powered hub kits!

After thinking about it, why would you carry the motor in a back pack when you could leave it on the bike??? the combined weight is the same !
It must be then that the motor drags when not in use. My guess is it's a direct drive motor.

Remember the "Elio"!( hope I am wrong" if it sounds too good to be true.,'Caveat Emptor".)
I have put a deposit on a "Cybertruck" and now I am beginning to wonder what the final product will be.
It just seems like a lot of kit to be put in a small mount, what I am hoping for is integrated e motor and transmission in rear hub. I am going to hear them out, though( because, if nothing else , I am a "neophile")

I like the idea of being able to easily mount a motor/battery kit to my light carbon road bike, to flatten out those hills, but as mentioned by previous posters the price is too high.

AND you have to carry the motor with you anyway. No weight savings.
