I am converting a 1966 Triumph T10 (like a vespa) to electric. It is old and heavy.
I need advice on which motor and rear wheel assembly to buy from you.
I was thinking of 36 volts, 500 Amps motor. is that good? Can you recommend one?
Also, I am trying to use the OEM swing arm and rear wheel, which has a large v-Belt pully on it. I can remove the pully and put on a sprocket (56 tooth?) but need it to free wheel when no engine...yes? is there a freewheel small sprocket for the engine side instead? I think that would be easier.
Advice and parts welcome, thanks.
What is the top speed that you want the scooter to go?
What is the diameter of the OEM rear wheel?
Here are the photos to go with last post
My target top speed is 30-35MPH, but a cruise speed of 25MPH for normal driving and good economy is fine.
The rear large pulley turns 5 times for each time the rear wheel turns 1 time. There is a reduction gear built into the hub.
The small front pulley on the engine is a CVT with variable diameter. That will get replaced by the electric motor and gear.
A 500 Watt motor only provides enough power for a top speed of around 15 MPH on flat ground. For a top speed of 25 MPH a 1000 Watt motor is needed. 26.8 MPH is around the top speed that I would recommend gearing a 1000 Watt motor for so the 1:1 gear ratio would work good with it.
If you want a 30-35 MPH top speed then a 1500-2000 Watt motor would be needed along with a gear ratio that would provide that top speed for the motors RPM.
The largest motors that we currently sell are 1000 Watts. If a 25 MPH top speed will work for you then please let me know and I will start working on a kit for the project with a 1000 Watt electric motor.
HI, thanks for reply. I think it will work fine with the no-bracket option, if those are 4 tapped mounting holes on the face.
See attached PDF.
I am most concerned with the length of the shaft, From my mounting face I need to go out 2.5 inches to the rear sprocket. I am looking into alternatives to remove the mounting hub on the rear wheel assembly to lessen that distance. How long is the shaft on these engines?
