My son and I are currently building PVC BikeCars... if you use 1-1/4" Schedule 40 PVC you can reinforce with 1" black cast or galvanized pipe for the basic frame. There is a americanspeedster.com offers plans for several models, but we are building ours to our own specs.

PVC Bike frame
I was reading the comments on Bike Forums and I would like to make a suggestion to the PVC bike frame builders. construct the frame using PVC and cover it in carbon fiber then finisn the outtermost of the frame using a fine fiberglass cloth. if someone tries this before I am finished please post the results to this site.

Sounds like it would be very heavy. You may not be able to get fittings that are needed to fit the different angles needed for a bike. I've done a little PVC plumbing. I don't think they exist. Hope I'm wrong.

Oct. 31 would have been a more appropriate date for a zombie thread resurrection.
Trick or treat a day early! PVC-flavored jellybeans? CF coated.

Well, today is October 31 and this Zombie thread has been resurrected twice since it was born as an obvious troll over 14 years ago. I can't believe it went on for three pages.

Pvc bi
I was thinking about using schedule 1" 40 CPVC. all I would need is straight pieces no angles. put the pcs. together in the shape of a bike then wrap with carbon fiber. Carbon fiber is a very very strong material, they current way a carbon fiber bike is made; they use Styrofoam or blow up plastic in the saps needed for a bike then wrap those blow up bags or Styrofoam in Carbon fiber. Surprisingly, I watched structural tests being done on carbon fiber bike frames and the carbon fiber is 10x srronger than an aluminum frame bike. that is where I got the idea to use PVC for a frame, I have never seen it done before but someone has be the first to do it.

Well, I did it. Just completed a PVC bike build. Used 1 1/2" for the top tube and down tube, 1" for the seat tube, and 3/4" filled with marine epoxy for the chain and seat stays. The hardware for the head tube, bottom bracket, seat post sleeve , and drop outs are aluminum I purchased from Calfee Designs. They use this hardware for their bamboo bike builds. The joints are wrapped in 3m fiberglass casting tape. I tried to post pics but was not allowed because I am a new member and do not have 10 post. Maybe after i answer a few questions I can qualify as legit.

Total bike weight: 26.2 lbs. Honestly, a little heavier than I expected. I guess all that stuff adds up.

To answer your question re riding , yes I have. As you might expect, it is incredibly compliant. The tire size is 28 but it has the feel of a fat tire bike. I am still getting used to it and confident of it as it very flexible, which is probably not a good quality of a bike. Cruiser pedaling is no problem but I am reluctant to crank down on it. All in all it's a soft it ride, different, and fun. Pics to follow.
