Four seat trike 3D rendering

The Bicycle Forest was founded in 1998 by Brent Curry as a bicycle rental business specializing in unusual bikes such as tandems, unicycles, recumbents, rowingbikes, as well as some strange one-off creations like the Couchbike, Family truckster, Hulabike, Treadmill bike and Customized Rhoades Car.

Along the way, Brent developed a bicycle design tool called BikeCAD. This has become a popular tool for custom framebuilders, bike shops and fit specialists. The program has grown to the point where it is now Brent's full-time focus. For more on BikeCAD checkout
