I've probably put on 500 miles now on my Sofrider 2, but had an unfortunate experience yesterday. Going downhill, perhaps 15-20 mph, it was as if the bike just took on a mind of it's own and began straying right and I didn't feel as if there was anything I could do to counteract this stray without crashing. Well, none-the-less I crashed anyways into a cement underpass and now my bike is in the repair shop and I'm sore and bruised. The challenge here is I don't even know what I did wrong. I've ridden this same hill in the past multiple times. Should I just go slower downhill or put feet down? Does anyone have any suggestions because now I'm a bit fearful? Thanks, Dan
