Saw this bike on Ebay, and was thinking WTH! You might as well just get a trike! I can see it for disabled riders, but for someone who just can't handle a bike, and needs these, I would say, you probably shouldn't be on a bike in the first place! Click the link in the ad to the youtube video.
People really buy this stuff??
