  • Best bike for the price!
I'm very happy with this bike, you can tell that it's not a premium build, however for the price of $999 its a perfect starter bike. The battery holds well and the dual drive makes climing hills a breeze, we did a bike trail with 1200ft elevation and the bike took it like a champ. We also attached a trailer for the kids and have been riding on trails with them and its super fun. The assembly was very easy, changing times are within the specs, just make sure to check every bolt and nut since some of mine got loose during shipping. ... show more

  • As advertised
Performs as advertised. GT20 Pro came with a charger per battery (x2) and assembly was straightforward. Performance is great and as advertised. Coming in just under 40mph at level 5 with a 200lb rider. Bike feels sturdy, and looks great. Day one review, but I'm very happy with the bike so far at 15 miles in. ... show more
