Bamboo is a very strong material with the tensile strength of 300-500MPa, similar to steel with 400–550MPa. Bamboo is not stiffer as carbon composites but much more crash-resistant very suitable for sometimes harsh conditions of cycling. We use madake bamboo (Phyllostachys bambusoides) the most common species in Japan. We also use laminated wood(hardwood and softwood) on chain stays and seat tube, as bamboo wood has a great weight to strength ratio.

As any other material used to make bicycles, our bicycles need a usual check and maintenance. The frames are painted with several layers of epoxy, lacquer and the last layers it is used two parts clear urethane with UV protective actives, protecting from the weather, moisture and insect attack. Even with the UV clear coat, we recommend avoiding storing our painted products in full sunlight, over time the UV rays may degrade the color of the paint.
