here is my trike experience
1. buddy had a greenspeed. more money, slow, low and I don't get the point. why make something heavier, harder to haul, more complicated etc.....unless you need the trike for disability.
2. rode GRR in colorado mountain ride. no trikes, OH yea, one guy was trike nuts and hauled the bike up all the passes on top of car. I take that back. Another guy had a trike, no use of legs. He hand powered his trike to the top only to haul it down the mountain do to lack of control. My hero.
3. I see no trikes in any compititions of any kind, reg bike or HPV.
I would suggest getting bent, two wheel style.
