I am owner for just over a year. A little shaky start but ok now. I ride 1 mile per day to mailbox and back. First thing I did to bike was install a bicycle type kick stand. 2nd major mod was to configure rear turn and tail lights to work as a brake light.
Pedal sprocket broke loose during a hard pull, but spot welded that back and it's ok.
I'm happy w/range and speed and love the hub motor. (Had a geared unit previous to cozybike).
It could use a little more hill climbing power, but assistance from pedals usually overcomes this.
