  • Rated 5 out of 5 stars

    Great E bike for beginners and overall use

    Overall bike experience is great. Worth it for a first time e-bike. The mileage you get is good too and ease of use. 15.5 mph is a good in between too fast and too slow. Granted I did get this when it was on sale, i'm sure for the price its at right now you may get something that's a bit better.
