Do you want to make your own bike with bamboo? You can do it at the Bamboo Bike Studio(工作室) in New York. People there can teach you how to make your own bamboo bike.
The studio is also helping build factories in Ghana(加纳), which is a country in western Africa. The factories will make cheap bamboo bikes.
Bamboo is as good as steel for building a good bike. Marty Odlin works at the studio. He says a bamboo bike is the wonderful everyday bike.
In Ghana, bikes are very popular. Few people have money to buy a car. And people like to use bikes to carry most of the country’s food and other goods.
