I’ve only put about 69 miles on my bike since I got it a month ago. I love it. I am 47 yrs old 6’ and 215# and this thing still zips. Lots of power. Occasionally I ride with other riders of various speeds. I have no issues at all coming from the rear to the lead bike quickly to control the group. The battery lasts forever without needing a charge, frame and rims are sturdy and nothing seems like it was cheaply made. Its assembly took less than 10 min your of the box. If I had to switch anything it would probably be the grips. I just prefer a different feel but the ones that come standard are fine. Can’t say that I’d change anything else. Great looking and fun to ride! Definitely took me back to HS on my BMX. Except this is much faster!
