Thanks Tom for the kudos! All of the bikes have 80cc (70cc) King's motors. The best upgrades so far have been the new style clutch lever (all but the top bike), chain roller (inline skate wheel), and 510 BMX chain.

I bought both wheels on ebay for $100.00 a few months ago. You might check with Mike Simpson to see if he still sells them.

Augie TRECK has some large beach crusers with coasters that is what we got for Sutan and he is 6'4" I think we paid around 250.00 for it and it is a good sturdy bike.

Where do you get those top chain tensioners that look like roller blade wheels? or do you have to make them? i need some thing like that for the top of my chain.

The bike I think Cookie is refering to is a Trek "Classic" and they are 229.99 msrp, come in a 21"; in vivid blue, candy red, metallic bronze, and metallic black/dark silver. I just took a look at one on the floor and I'm not so sure an engine would mount in easily...maybe. The womens bike could take one though I think. This info is in regards to the '07s only.

Not that anyone needs a new bike, but just to fill in the information gaps for future reference.[/b]

Yes you make them on a lathe or drill press using an old flat blade sharpened screwdriver to make the grove.

Maybe this will help.

That was my guide roller in the link Cookie referred to. After re-reading that it does sound complicated. Using a seat clamp like you did is nice and clean...easy too. :grin: Having that roller sure keeps the chain rolling smooth.

I like your bikes. They look comfortable and safe with plenty of brakes. :cool: I've got a drum brake setup to put on one of these days.

Drum Brakes on a Bicycle

why would you want drum brakes they are way less efficient... (in cars at least)
Drum brakes are great! Check out an 18 wheeler and see what kid of brakes they have!

I have used a drum brakes on my bike and it stopped me better than rim brakes.
