20 inch old school

My latest effort.

Features:-

Banana seat and high bars

35 tooth sprocket running without tensioner.

Black & Silver colour scheme.

Needs more accessories I think, old school lights, mirrors ect.

 

Cool to see another motored sting-ray! What kind of rear hub/sprocket do you have on that?

 

The rear sprocket is a custom made from 5mm alloy plate and a chainring of an old mountain bike. The hub is a standard coaster brake.

 

How does the bike ride gearing-wise? I have the stock 44tooth on back of mine, awesome low end but tops out at about 27mph. Here's my bike:

 

Using gearratio.exe and allowing for a 21" tyre diameter 6000rpm should give 26mph

You must be pulling around 8000 to do 27! allthough your tyre is taller.

I would love some more chrome on mine, still don't know if its a seller or a keeper yet.
