I bought this one last year and love it. I put over 1500 miles on it. I'd suggest replacing the seat though.

Battery lasts me about 24 miles. I ride it practically every day. I just got my first flat tire on the back tire, and it took me about 1.5 hours to change it. I was worried at first, but want too bad.

Has 4 different pedal assist speeds (11,13,15,19) mph roughly. Or just push the button and go with no pedaling.

No problems riding up hills.

Charges full over night.

Gears change smoothly.
