Trader on Alibaba won't honour their warranty.
We purchased 7 Ebikes from Shenzhen Shenhai Mechanical and Electrical with good warranties. As soon as the 1st warranty claim was submitted, they fell off the radar. I submitted a complaint to Alibaba but all they said they would do was put a comment on the sellers mini site, a slap on the wrist with a wet bus ticket. As a minimum, they should have barred them from trading on Alibaba. However, after discussions with my colleagues in New Zealand and overseas, we have decided to severely restrict our trading through Alibaba until they sort out an amicable solution to this situation. Alibaba should not be seen to be supporting dodgy traders that do not honour their warranty periods on their own merchandise.
