Hello, I am sorry to go against Bob's recommendation but in this case I feel I need to. I purchased an Lectric bike 13 months ago, I have right at 100 miles on it. The battery controller is failing so I called Lectric to see if they could help. They said is was very rare that the controller would fail so soon, but I have to pay for a new controller because I am 30 days out of warranty. So, they say this situation is very rare but they would not stand behind their product and help a customer out. If they don't have confidence in their product, how can we, when we use these bikes for transportation, sometimes a long way from towns. Just something to be aware of, they will not help you even in a "rare" situation.
