It's certainly an interesting way to add electric propulsion but........

Not acting through the drive-train = no good for MTB.

 

[Stefan Mikes]

what do you mean by not acting through the drive train?

I might have misunderstood the video but I saw the guy was attaching the motor to the rear wheel (right?) The mid-motor acts through the drive train. Meaning, downshift to the granny gear 36-51 on an e-MTB and your Yamaha 80 Nm motor will produce 120 Nm at the rear wheel.

I thought it was attached to the rear disc.

It doesn't matter where it is attached. It is not at the crank.

I thought it was attached to the rear disc.

That picture explains it fairly well, as I didn't see a clear description on their site.

Adding a gear and motor to the disc brake is certainly different, basically it's an "external" rear hub drive.

If it's easy enough to disengage without removing (with zero drag when off) , it could be an interesting "I REALLY hate this one climb" solution for those who don't necessarily want a full eMTB. Also, with the "disc gear" being the only integrated piece, it becomes a "one motor for multiple bikes" solution (if they sell the cog separately).

I could see the appeal, but I see they mention "programmable throttle" but how? I don't see any cockpit controls.

Their promotional video is the lamest thing I have ever seen....

Brake-mounted Elevate makes mountain bikes electric

There are now a number of kits that allow users to temporarily convert their regular bike into an ebike. While most of those involve swapping in a powered wheel or wheel-roller, Elevate is different – it's installed over the rear disc brake.

Looking at the pictures of how the motor drives that gear I would think it would be a pretty loud machine.

Reminds me of the old Currie Drive I had 20yrs ago. Granted it wasn't easily removable....but it actually worked pretty well but the 24v SLA battery wasn't good for long rides....
