I bought my Velovie Vitesse 300R less than 6 month ago and only took it out on nice days for less than 300miles. A few weeks ago I was slowly pedaling on a flat, when suddenly the rear derailleur hanger broke.
The derailleur ended up in my rear wheel, bending a spoke and breaking off a piece of the frame. (See pictures)
It was immediately clear to me that this must have been a manufacturing and/or material issue, as it was a basically brand new bike. However, after contacting customer service, this was their response (after more than 2 weeks):
'After reviewing this issue and talking with the factory we find that this is not a warranty issue, as this was not caused by a defect in materials but rather a maintenance issue.'
I have asked multiple bike mechanics / dealers, and everyone told me that this is not a maintenance issue at all.
Customer service at velovie is absoltuely not responsive. I really should have stuck with a name brand....
