I only have one complaint , it would be that the video for installation could be a little better. But over all the experience with this purchase was great and the item is packaged well.

Fast shipping Fast shipping, well packed, arrived in very good condition, all assembly tools included. Rear derailleur adjustment should be checked.

M026TGB bike review Really like the bike. Assembly was straightforward. I would increase the length of the seat post as it was too short and had to buy new ones on both bikes. Also a key or some mechanism to ‘turn off the bike’ would be good so the battery can be left on the bike if on a rack while in class and not in use. Overall, really like the bike.

Battery mount on the fat tire bike is…junk! Battery mount on the fat tire bike is the worst thing ever! It broke apart and the 3 mounting screws are a joke for such a heavy battery. Bike is dead because it looks like the motor controller smoked and now have an error 30 code. Also you have to get parts from china with a 20-30 day delivery!!
