USERS’ PLATFORM Composites in the world Bamboo bike This bike is made from Bamboo that has been smoked and heat treated to prevent splitting. The vibration damping of this material is a performance advantage on longer rides. Each frame is built to order and every frame is a unique. Tubes are selected for the weight of the rider. Lugs are available in carbon fibre or hemp fibre, for the allnatural look. The chainstays are available in carbon fibre for extra stiffness in the drivetrain.

It goes from 0 to 500 km/h in less than 30 seconds thanks to its low weight of 360 kg. Its body and structural parts are made of carbon, aramid and titanium alloy.
