Hi Guys,
Iv'e been trying to run a motor (electric) on my spoiler for sometime now and I keep blowing them due to not knowing anything about gearing ratios etc. I ran my motor(s) direct to a sprocket on the rear wheel.
11 tooth sprocket on motor
54 tooth sprocket on back wheel (mini moto sprocket, 8mm pitch).
The 54t sprocket is the bigest I can go without interfering with my discbrake. I had to make a mount to move the caliper out back a bit.
First setup.
This ran ok with 3 heavy old SLA batteries, that I put in a filing box on the back rack.
I then moved the motor to this postition and investedin some lighter lipo batteries...
I have just invested in my 3rd motor - A Cyclone 1200w and a new speed controller - (that I need to figure out how to wire up).
Having blown my other two motors, a 36V 500W and a 36V 1000W, I was thinking that Im going to have to jackshaft the cyclone motor. But sadly I know next to nothing about the gear rations thats invloved. I then saw this spoiler while browsing the web.

Theres not to much detail about the build on the link I provided and the builders website lookslike it no longer exists?
It was this picture that caught my eye...
Does anyone know how this was done? ie what type of adaptor/sprocket configuration would I need to be able to have two chains to the rear wheel. One for the motor and one for peddling.
This would save me having to make a jackshaft.
Regards
Tom
