My boyfriend built the electric bike for me, and he said that the assembly was easy and the manual was easy to follow. However, one of the issues with the bike is that it becomes quite heavy, which could be improved. Additionally, it would be helpful if a bag was included to carry the battery pack. As a woman, I don't have pockets that are long enough to fit the battery. Therefore, a lockable pack or something that can be installed on the bike to reduce the risk of theft would be great. Lastly, it would be helpful to have a feature on the screen that displays the time or battery warning.
