Additional Metal Parts
Can I make the size that’s right for me?
Our design allows you to build any size of any type of bike. For each size, we select the right set of bamboo for you and provide the right drawings and tools. You’ll choose the instructional drawings from the bike types mentioned below but you can customize to your heart’s content. Once you get the idea on how to do this, you can make any kind of bike. It’s a good idea to start with a “normal” bike for your first try. Then you can see the possibilities and build any kind of bike!
MTB is available in 26″, 27.5″ and 29″ wheel sizes.
ADV/CX models are available for 700c and 650b options combined in the same geometry. We do not offer a 46cm frame size for this model type. Please follow the sizing chart above.
BMX will soon be offered in a 20″ frame but we’ll soon offer 16″ as well.
Rear Spacing: Our tooling is designed for 130 mm and 135 mm rear spacing.
Dropouts: The dropouts are able to accommodate disc brakes and derailleurs but are also slotted so you can make a single speed or internal gear hub bike. Thru Axle dropouts are not available at this time.
Head tubes: Available for use with 1 1/8″ steerers and 44mm (tapered) forks.
