Innovative Bottom Bracket design for a mountain bike from “tomorrowbikes”

“About two years ago I saw a vedio about Calfee Design bamboo bicycle, that attracted me and I began to make the bamboo bicycle by myself.
I made several bamboo bicycles and now I treat it as a habit.  I spent most of my off hours to research and build. Pls see the attched files for one of my bamboo bicycle.
As you blog wrote every details of making the bamboo frame—but I can’t open most of the pictures, I compared your process with mine, most of that is similar.
I treat the seatpost very simple—I have a hand tool can dig the hole into the poles for the dimater (25.4 or 27.2) as I want, so I just dig the hole and put the seatpost into the bamboo poles, and then  lock  on the bamboo poles. I didn’t use a metal poles into the poles as you done.  The bicycle I rided over 3000km and still OK. ”

One very interesting thing about this approach is the use of foam blocks.  Clearly this reduces the amount of epoxy and fiber you have to use while cutting down on weight.  It’s not clear to me whether the ends of these tubes have been mitered or not.   This approach is much more like that used on carbon fiber bikes, where a foam frame is built, carbon applied and then the foam gets melted out using acetone.  I would assume they leave the foam in here.

  1. Hi,
    This blog is great, you collected a lot of information here.
    I already made a bamboo bike last summer and it works perfexctly. Now I’m working on the 2nd, improved one. Unfortunately I don’t have a “how to do ” description, but It is planned…
    There is a photo of my bike in the website I linked.

  3. Hey, great work!
    Maybe we will build a bamboo cargo trailer.

    (Also, do you have pics of your Kayak project somewhere?)
    keep on biking!

    Hey, hoping to build a bamboo bike of my own but I’m having trouble finding a suitable supplier that will ship to Ireland. Anyone out there know of any European based bamboo suppliers or reliable suppliers who ship internationally?

  5. Nice to see more amateur builders enthusiastically building these bikes. Its like wood strip canoes, regular folks just like the build process more than just buying a pre-made one – interesting!

    I made a bamboo fixed gear using some of the good information on this site. Thanks!

  7. I finished the world’s first bamboo snow bike:


    So far it’s seen a good amount of summer use, and has survived lots of rock gardens, a few crashes, and a handful of 1 foot and 2 foot drops.

    Here are a few that me and my buddy made:

    These are bamboo bikes 7 and 8 for us, we have three more that will be done this month. We started just doing it for fun in our spare time a few years ago, but so many of our family and friends want them, we’ve just kept on going.

    • Evan, I like your split-top-tube-into-seat-stays approach. Been thinking of doing a similar one, glad to see it put into reality first. Your joints look very nice as well, thumbs up.

    Thanks for looking, and for the comment Drew, very nice of you to say. Thats a bike I built for my wife, I’ll post pictures of my road bike soon, it’s a black bamboo bike of similar construction to my wife’s, but it needed a third tup tube brace that bends down to meet the down tube for added stiffness. My wife is small and light enough that she can ride that bike fine, but for me (6’1, 210lbs) just having the two beams was a bit springy. three makes it nice and stiff. If you’ve been thinking of doing it you should, its fun. I like the pictures of your stuff, I haven’t done a mountain bike yet, its on my to-do list. I love talking shop with other builders.
    Cheers

    Michael,

    Your blog was a tremendous help to me in my project too. I also make split bamboo fly rods and wrote an article for an online rodmaking magazine about building the bike. It can be found in the July, 2011 issue of Power Fibers
    (www.powerfibers.com/PowerFibers_Issue_44.pdf) on page 38.

    Thanks,

    –Robert

  14. Hi Mike,

    I tremendously appreciate your site, it really is among the first places to go, if your out to built ur own BambooBike!
    I just started my own project and I certain your blog is gonna be one of my topsites within the next months;)
    I’m documenting my project on bambusvelo.com, where I want to show , that it’s possible to built such a bike without being a bike nerd prior to the project ;P
    So if u got a spare sec, have a look around. I could use some help in the design process. (It’s in German, but I’ve built in Google Translate, so I hope u can get most of it)
    Anyway, thanks a lot again for the help ur already providing through this page!

    Cheers
    Jan

    Hey man!

    Well, it’s been a long four months, but I’ve finally done it! I’m a beginner bicyclist and I suppose frame-designer now, and I followed your detailed instructions to the letter. I’ve ended up with an attractive single-gear bike like I wanted! Thank you so much for this blog!!

    If I post a picture of my bike, will you put it up in the gallery? Thanks for the inspiration!

  19. Going to make a cross country 5,000+ mile trip on a bamboo recumbent bike to bring awareness to human trafficking, and raise funds for the victims of trafficking…

    Anyone know where I could find plans to make a bamboo recumbent?? 🙂

    This site was an incredible help for my project. I followed pretty closely the process that you used, and my bicycle turned out great.

    I did mine for an elective course in my mechanical engineering program, called ‘Single Track Vehicle Design’. I completed the bike in only nine weeks, start to finish. One of the biggest challenges was heat treating the bamboo; the only decently priced bamboo I could find was still green, so I had to figure out how to dry it–and quickly!

    As a result of this being for a class, I did a full engineering report. It includes the full fabrication process with several photos, technical drawings, a complete set of engineering targets, cost analysis, weight analysis, and heat treatment data.

    Thank you so much for keeping this site here, couldn’t have done without it. 🙂

    ” It’s not clear to me whether the ends of these tubes have been mitered or not”

    Looks like it’s not. Their faq section explains how they used to miter and tack with epoxy filler then decided to switch to making the foam lugs into which they butt the square cut tubes.

    My bike: http://flic.kr/p/dwrJ5K
    Almost finished. It’s rideable now, but still missing the front derailleur (seat tube doesn’t fit standard clamps, will try a fiber-resin attachment for a braze on derailleur) and shifters (waiting for the bar end adapters to arrive).

    Thanks for all of the valuable info!

  24. Hello! Take a look at our upcoming bamboo bike build/tour! We will probably be fairly busy on forums soon, as we are sourcing materials and gathering the group of people now!
