TerraTrike Bike Parts & Accessories
TerraTrike is a U.S.-based manufacturer of recumbent trikes. The range is available direct from the company or from bike shops across the U.S. and Canada, and a few shops in Europe, Asia and Oceania.
The company's recumbents are moderately priced, intended to get people interested in the novel ride of a trike; complete builds start below $1000 US. They're built sturdy, too: the entry-level Rover can carry up to 400 pounds. Accommodating to casual and serious riders alike, seat angle can be adjusted from a newbie-friendly near-upright down to an aerodynamic 20 degrees above the horizontal.
Build kits for all price and performance points are available, pairing with frames in hi-ten, 4130 chromoly, and aluminum alloy. There's even a tandem!
TerraTrike makes a good and inexpensive recumbent trike. Stop by your local shop and try one out - you might love it.
