I researched this for years before buying the ICE Sprint. In the end, it was an easy choice. --DW

Hugh: Thank you very much for helping me get onto the right trike for me. I am quite pleased with the upgraded version of my Terratrike and I have been able to already make 3 different runs in excess of 10 miles each round trip.

Congratulations, T, C, and J on successful completion of the Shifting Workshop and passing the Practical Exam with flying stars!

There's no fooling you with random adjustment of limit screws and barrel adjusters.

Greenspeed is a pioneer in reumbent trike technology. The Greenspeed GTO model was arguably the first commercially successful recumbent trike and the vanguard of the Recumbent Revolution.
