Just got the call from Bigdog. They said since I put a belt drive on my bike, the powertrain warrentee is over. Otherwise, they would have. I have to pay for the new EHC all on my own. They said your now on your own. Well I am now not a big fan or will ever reccomend them again. It's a sad shame. I am in with anyone that wants to sue, start a class action lawsuit. I will look into it on my end. This defect is to widespread for them to say screw you. Bigdog is now just another low level over priced bike company.:angry:
