My motor failed but it was still under warranty. Stromer sent me to a dealer to diagnose-verify that it was an warranty issue. The dealer filed the warranty papers and told me Stromer was sending me a brand new motor. I picked up the bike and brought it home after the work was done. I just noticed my bike is an 8 speed now and not a 9 speed-the cassette is only 8 gears. This leads me to believe the dealer used a motor off an original Stromer. Is this the way Stromer has dealers fix warranted parts? Can anyone give me the name and number of a rep I can talk to. I can never reach anyone at head quarters. Any help would be appreciated.
