Oh, it's cool. I fell down a flight of stairs on it, thought it was a ramp, lol. Not the bike's fault though. The main sprocket came loose, unrelated to the crash, and was nearly stripped out. Not sure if it's a common problem or not. I had only rode it for a few hours at that point. Everything else is solid.
The box said 2023. It's been good so far. I haven't got the chain wet, so no rust. It should always be kept oiled anyway so it can't rust IMO. I've heard it's not a top quality chain, but no worries to far. It's a single speed bike so I don't have to worry about shifting performance. Chains are cheap to replace. Taking out this weekend, at an indoor bike park, so we'll see how it goes.
Ha. I did about a 750 one time (Over-rotated), and I took a handlebar to the ribs. I couldn't talk for about two days. I'll see if my old body can do a 360 sometime, and try to get it on film for you.
Ah, it would depend on how tall they are. Generally, no. This is for about 5'9" to over 6' tall. They have other models that would probably fit better.
