20 plus MPH!!! Wow, that's flying - wheels a-singing and the scenery rushing by. If you ever fall at that speed IT WILL NOT BUFF OUT!!! 8-) I just crank along at 10 to 12 MPH and enjoy the feeling of motion and watching the scenery as I go. If I could ride a "Go-Faster" bike I would cuz I love speed too but I can't because leaning over forward and tipping my head back to see puts my arms to sleep so I ride sitting upright and that way nothing gets numb. You do what you can with what you have where you are. Hey, that works for me. 8-)
