whizzer style bike

I think the wheel pulley will be on the large side - meaning with a HT you will be revving real hard and going real slow. If you put a jackshaft between the HT and the wheel you could get the ratio back up. wouldn't it be easier to just use the chain drive from the kit.

Paint the chain brown?

use a big timing gear pulley for a rear sprocket, and a little one on the engine.

y'know, i was posting this jokingly, but that'd probably work. wouldn't look old-timey, but it would look motorcycle-y...

You might consider replacing the sprocket with a pulley. Might take some minor machine work. Another option is to over-lay the pulley over the sprocket [if there is room].

The original Whizzer rear ratio was 3.5" to 15", or corrected rea drive ratio of 4.43 X 1. It would be similar to a 10 tooth drive sprocket and a 44 at the rear wheel.

I am a collector of Whizzer motorbikes, and have at least 20 in my collection, therefore I am very familar with belt drive.


Have fun,
