I rode a few miles to work. It is downhill there in the morning. It made some noises ( I hear the turn of wheel and crank/pedel. I ride on the street/sidewalk. I got in a wreck trying to jump up the curb, since the bike has coaster brakes, but I landed on the grass after going over the handlebars. i like not having to adjust brakes, i feel more safe. The bike wasn't phased by the crash, i rode the same. I'm sure I was not going to fast on the bike. It works for me its seems to be reliable. I do not feel the back tire is going to pop. I traded the bikes handlebars for a set like ones on a mountain bike, so it feels like I can maneuver. Like the bmx I rode as a kid. But it seems solid for my 275lb 6-3" frame. I was worried since my new electric bike back hub broke and the tire went flat on a ride. My back wheel came apart after a year, maybe 3 months of regular riding. Do not buy a bike from best buy unless you know what your getting they can be no help. Customer service went quick with sole they got back to me through email answering my complaint about the noises I heard riding it the first couple of mornings to work, it quite here early. Thank for a good product.
