I ride a recumbent trike simply because I have crashed my bikes too many times to risk getting hurt any more. The most recent crash changed my right knee forever, not for better!
I admit, I'm too uncoordinated to safely ride a bike....never was able to learn how to get my front wheel out of trouble and keep it on the ground when encountering a road hazard. Chewing gum and walking at the same time also is not a good idea for me...I end up tripping on my own feet. Also cannot throw or catch a ball.
Don't get me wrong, I'm not entirely a lost cause...I can play guitar like nobody's business. It's the small muscle groups where my skills lie, but I don't play the guitar while riding my trike....!!
