Their is a electric hub installed already and I would like to attach a sprocket to the wheel spokes or the hub itself. May not to do what I want to but need advice. It is a Schwinn StingRay Electric. I have looked at it and thought about going to the front wheel but don't want to do that. I am thinking of mounting the engine above the rear wheel and running the chain down to the sprocket. Open to any ideas.
I don't understand how you intend to use a jackshaft when you don't have a sproket to drive the wheel. The bike already has an electric hub motor on the rear wheel, I want to add a sproket so I can power the rear wheel when I don't run the electric motor. This way I will have a hybrid bike, 3 way peddle/ electric/ gas.
Any ideas will help.
You've got a hub motor....I assume it also has pedals with a chain going to their own sprocket on the rear?
The jackshaft uses your existing chain and sprocket setup (for the pedals) to get the power from the motor to the wheel. So if you've got pedals and you use the jackshaft kit, there is no need for a new sprocket on the rear wheel. make sense?
Are there threads that I see here?? On quads for the rear axle they have really thin axle nut's....is it possible to mount sprocket here and use some axle nut's to mount it Don't know too much about E-hub's
I don't know if that would work and I thought of that also. I guess that I need to see a breakdown and operation of that drive hub, will have to do some reasearch on it.
The hub is only 250 watt 24volt and runs about 14mph, would like to have a little more speed and range.
In all honestly I still think Pablo's kit would be the cleanest solution. Not cheap, but clean and would work well. Then you don't need to install a new sprocket on the rear wheel, it just uses your existing pedal/chain/gears setup.
Looks like a big hub....What material is it made of?....I wonder if some "studs" for a 9 hole mount sprocket could be welded to it then simply use washers to space out a sprocket and bolt it directly to the large hub....
