This is more of a build log now that I've started getting parts for the build. Below is the original first post and dumb questions etc.
I'm interested in doing LiPo, RC outrunner, CC controller, etc. build as my first ebike build and it would be great if you guys could give me any input on the stuff listed here.
Batteries
44v 10 or 15ah of turnigy lipo
Controller
CC HV110
Motor
HXT 63-74 200kv (the one I'm running in my scooter)

"Schwinn Full Suspension Bike with Front Disc Brake"
Or something like this bike. You get the idea
For the proposed mechanical setup (this is drawing off of a number of builds I've seen here)
The reduction would be:
RC motor (with 11t #25 sprocket already attached) chained to a 50t or so sprocket which would be on a shaft that would be connected to a flange bearing on the same mounting plane as the motor...
And on the other side of the plate/shaft, a 9t bicycle sprocket (#40 chain, right?)
The reduction/motor shebang would be connected by chain to the largest sprocket/chainring on the front cranks.
Would these old freewheeling cranks work?

Or would the freewheel be not nearly strong enough?
And then of course the other sprocket/chainring would be chained to the back wheel chainrings. I know I would lose front crank shifting, but would I be able to shift in the back still? Or would the torque cause problems with the derailleur?
The goal of the build would be to have a fun, fairly reliable bike that can go 15-20mi on a charge and 30-40mph max. Oh and hopefully I could keep it under $800
This is all completely theoretical, all I have is the motor and it's still on my scooter So feel free to tell me it won't work at all or something like that. Thanks in advance for any advice!
