I am new to ebikes as of this week. I purchased 2 2017 bikes from a couple here in The Villages Fl. We got 2 Bintelli bikes one being a B1 for her and a M1 for myself with less than ten miles on both. We also got a bike rack for the car and a new pet trailer for $1100. I am having battery problems with The B1 bike 36v10ah. Thanks for letting me join and learn.
