Ok, so maybe I hadn't rode a bike for a year or so before I got my RadMini. And maybe I don't know the correct seat sizing / setting for this type of bike. In any event, until just now it was very difficult for me to get on and off the bike, and to stop and start the bike. Going back to when it arrived, after assembly I got on and almost messed up my knees trying to pedal the bike. The seat was all the way down, and my knees were bent like crazy. Ah yes, "When the pedal is almost down and the leg is at its furthest extension, the knees should just be slightly bent". I fiddled with the height of the seat, and set it. Nice - lots of power when pedaling, and very comfortable. But, with that seat rising up in the air so high, I was either going to need a ladder, or was going to have to lean the bike almost flat to get on and off. And when I went to stop, my feet did not reach the ground, so I was forced to jump forward and straddle the bike (I have fallen a couple times though). I learned to live with it, but was not happy. So today, I decided to revisit the seat height. I lowered it so I could touch the ground with my toes, or lean slightly and put my foot down. Pedaling was not quite as powerful as before, but I think it is close (I wouldn't win any races before anyway). My knees feel the extra bending a bit, but I think will be fine. All in all, a completely different and I think better and safer experience.
