I have a couple of questions.
1. I'm attracted to the adjustable backrest and think it might help my lower back. However, I wonder how much cushion the rider gets when you hit a large bump at speed? Does the bike absorb the shock, is it transmitted up your spine, legs?
2. I'd like to be able to commute with this bike going a true 55mph. Is 55mph for 20 minutes a shot too much for this bike? Does it get buzzy?
appreciate the help
