built it up,got it running,tore it down,sandblasted the parts,....next paint!

Nice motorized bike build. I want to build one of these creations in the future.

Is that a Stanton gear box? What's the ratio like?
It's gonna be sweet,man. Very nice.

Yes it's a staton kit.The gear box reduces 18 to 1 and I'm using 26" sun MB wheels.I'm not sure of the final gear ratio,but I'm 180lb and the 33cc robin(4 stroke engine)would pull from a standing stop on level ground.But doing that would burn the clucth in short order.My guess is it runs at about 20+MPH.This build also uses the Staton inside drive which is a bit harder to install but centers the motor and makes the overall balance better.Can't wait to get her back together and purring.
Now dreaming of a motored velo car!---sam

I bet a larger rear sprocket by the wheel will help your clutch along in the low end.

Yes but it would also lower top speed,and at about 20mph i don't want to lower the ratio and drop the top end speed.Manny seem to build motored bicycles and want then to do (motorcycle)speeds...30/35+.These kits/motors only have 1 speed and operate like a weed whacker.There is ways to get different ratios or 2/3 gears.Staton sells the NuVinci hub which acts like an old sturmey archer hub only with no fixed gear changes but about the same low and high gear---staton says with this low gear you can pull the bike off from a stop.But with the base kit you pedal to get under motion then power up,this is not a problem,and I kinda like still having to pedal even if it is to only start.
If I ever do build a recumbent/velocar I'd use the staton with a NuVinci hub.The field to build a motorized sports velo car (with gears) is wide open--just think of a 60s bug eyed sprint type roadster velo car,or micro-corvette!! Not only cool--but useful too---sam

do you have to pedal before engaging the engine...so its rolling start

The answer is no,the engin is a pull start,after it's running all that is required is to turn the throtle.These small engins of the weedwhacker type have a small clutch,so any hard pull would shortin their life.It's best to pedal start/just get the bike rolling,then hit the gas.Easy to do,one spin of the crank is about all that is needed .Some engins you have to pedal start and come with a cluch with a lever.I prefer the staton with the auto type cluch.

Nice to see a pair of pressed steel Webb forks being used :thumb:

Annie,I had one of your countrymen lookin for a set for me going on two years now---he mostly just gave up---but then this frame and fork poped up on ebay and I got them out of Au.They were used on melvern star autocycles and bsa flyingwheels,maybe others too.
If you ever see a set(cheep)let me know---sam

They are really really hard to find Sam, - I don't know why that is. :(

BUT if I do locate a set I will let you know :thumb:
