My wife and I want to buy the RadCity and RadCity step thru, so we test drove them recently at a rental location in CO. Loved everything about them except the ride was very harsh on both. Yes, I know about suspension seatposts, but we own 8 bicycles, or all types, and never experienced such a jolting ride over typical sidewalks and pavement, with or without suspension. Briefly rode the RadMini, same harsh ride. Maybe the tires were at 80 psi, and 55 would help. I would appreciate any feedback from owners.
