Crazy idea: Wheelchair motor mid drive.

I had some wheelchair motors. These are insanely heavy duty brushed motors made for pushing fat people around town. The motor is 24v, and can be over-volted.
It has a gear down reduction, and the shaft goes perpendicular (off the side) of the gearbox. It also has an indention that easily makes the whole thing mount to a bike frame, pre-threaded to bolt to a frame.

I removed the electronic brake, and then I tested it on my Kelly KDS72200E (120A continuous 200A max 72v controller). Worked great when ran at lower voltage. The next step was adapting the driveshaft to accept a sprocket. I managed to find a shaft adapter and a one way sprocket.

The big question... is my idea stupid? I haven't actually gone through with finishing things yet. I don't do E-bikes, mostly electric drive stuff. Comments/criticisms welcome
