It's true these $#*!s don't call anybody back. Unless you don't know any better and are interested in purchasing one of these bikes.My sons bike was delivered damaged. We had to pay to get it fix.My husband ordered a 2nd battery for his bike.The warranty hasn't expired and. BPM Imports isn't honoring it. Now what sucks is that im pretty sure the positive reviews come from new bike owners. I'm retired.so I have nothing but time to insist. That these crooks honor their BS warranty.
