Framebuilders Thinking about a custom frame? Lugged vs Fillet Brazed. Different Frame materials? Newvex or Pacenti Lugs? why get a custom Road, Mountain, or Track Frame? Got a question about framebuilding? Lets discuss framebuilding at it's finest.

I started a thread about this thread over in CarFree Living. These bikes are beautiful and I also wonder if they would have an impact on societies where petroleum-derived materials are in short supply.

My bike does not trip the ones we have around here. Curious if you ran into a similar thing.
hmm, we have a traffic light downtown that works sometimes. there are a few more around the edges of town, i dont think any of them have metal detectors in 'em...
mostly speed bumps are used here to control traffic, sometimes installed by official government workers, but more often built by folks who organize in the neighbourhood after a child gets killed by a car or somesuch. I really like speedbumps, because they MAKE cars stop. A light has nothing but moral authority.

you know the seattube and the seatstays and the fork and the handlebars are metal tubing, right? as is the rack, they are just wrapped in rattan.
i really like the fenders, though!

Yea, I think the only things that are bamboo in the frame are the down and top tubes. Still a good looking bike and it sold for only $150.00.
I couldn't do the rack for that.

I believe it is made by the Hangzhou Xinnan Rattan & Bamboo Works.

spring cleanup.

It is spring in chicagoland and all the trees have been or are being trimmed.IT makes me think after seeing some bamboo bikes here.There are Lots of frame tube sized branches available for a skilled woodworker to craft into bicycle frames.

Hey wakamole, did you order your bamboo locally, or from overseas?

Well, I think I'm going to see if I can't make it happen here in CR. You guys will probably be getting a lot of PMs over the next couple months.

Wish me luck.

will you be getting fresh bamboo? I was there back in March and it looks like you have a lot of areas that you can get from. good luck. Make sure you dry it first

Fresh bamboo then fire-cured. Apparently the oils come through the fibres and make it super strong and create a natural varnish on the outside.

Wrecked today. It was not that horrible of a crash, however my frame is completely shot.
I think it's durability is the largest reason bamboo is not commonly seen as a frame material.


I will most likely not rebuild this frame.

BTW, I went down in some sand on the road. The front rack snapped off splitting the downtube to flinders.

hey Allan
I hope you weren't hurt!
(just your feelings? he he he)

can you post a pic of your ex-frame?
could you have made it stronger in hindsight?
more hemp on lugs?
different curing method for culms?
thicker bamboo?

wow allen, sorry to hear that. i just completed my third frame, with mountain geometry, and i think it is the best ive made so far. i will post pics soon.
i hv heard from calfee that bamboo is actually very crash resistant, i wonder what happened with yours....
id be interested in seeing the pics of how it failed

It took me a day to get over it. It's a learning process, apply what you know to the next.

The frame failed because of the frame mounted rack.
1.) When the rack, which protrudes from either side of the frame by about five inches, hit the ground it put a lot of lateral stress on the downtube, splitting it.
2.) It could have been exacerbated by the way I cured the bamboo. When researching curing, one of the techniques I read about was smoking. I'm going to explore the differences in curing and strengthening methods.

I don't know if smoking is a poor curing method, I will however not use a frame mounted front rack on bamboo in the future. It does give me a frame that I won't feel squeamish about conducting some extensive destruction tests.

The lugs have held remarkably well. They show no signs of cracking or failing. When I formed them I did take into account fiber orientation. The frame did have some flex in the main triangle due to the geometry. Next time I build a similar frame I think creating a bracing structure at the headtube, tying the top and bottom tubes together, would be beneficial.


Where the rack mount came loose.

Sorry about the low res image, the only camera I have at hand is the laptop's. My real camera is at my studio, I'll grab it and post some better images later.
