My man is notorious for bike accidents. Three big ones in the past five years. First time he busted his arm; second time his wrist; this last one he was lucky but still two months later the swelling hasn't gone down in his knee! So we (I) decided training wheels were in order. He has dreamed of owning a TerraTrike for a long time. And he has been eating so healthy and has lost nearly 30 pounds this past year, so frankly, he deserves this reward.
