Bests & Worsts Reviews from Amazon

I have RETURNED this bike. I'll tell you why. I got it on time, probably the only thing that went right. I put the bike together, a little hard but figured it out. Tried it out. Found that the tire tread was to cheep to drive it safely. You try to turn at any speed and the tiers would slip and you would almost crash. I replaced the tires and that seems to help. It worked well for a week. The battery seemed to not last that long but it went about nine to twelve miles. About Thursday it shut off while I was riding it, I thought the battery might of died, got it to turn back on and got home. Worked fine on Friday. Charged the batter Friday night. Got up Sunday morning to go to work and the bike would not turn on. Took me ten minutes to get it on then I peddled for 10 feet and it turned off and never turned on again. Contacted Ancheer would only contact me once during the night. Showing that their customer support is in Asia. And on top of that they used google translate to read the email. They wanted a movie and pics of what was happening which i was happy to provide to get the bike fixed. They looked at the movie and said it looked like the controller and the meter. The battery was still working, the horn and light works fine. They sent the part they took a week or two to get to me. I replaced the parts and it still didn't work. Contacted them again and they stated the whole thing over again, wanted movies and pics and said it was the battery, that I needed to see if the light and horn worked, I sent them video of everything that was happening again. They said that they would send a new meter and controller again. I responded that I already replaced those and if I got bad parts twice then this bike is crap, and that they don't review what is happening with each case. So I asked to return the bike for a full refund and to have them pay for shipping. They ignored that email and asked if the batter was working. So after a month of trying to get it fixed I finally contacted Amazon and they said they would look in to it. About 24 hours later I was contacted by Amazon saying that I could return it to Ancheer but I had to pay for the return. That same time Ancheer sent me an email saying they could send me a new battery. The next day they finally sent an email say that I could return it but they said that it was too much to ship so they would suggest that I take it to a repair shop and have it fixed. I don't live by any repair shops that deal with electric bikes so I paid to have it returned. I had to send the tracking info to Amazon and Ancheer. Ancheer responded with just this"We'll check it later." It was delivered about 3 business days later. A week after delivery, with no response from Ancheer. I final sent an email to Amazon and Ancheer to ask how my refund was going. Amazon said they would look into it and get the refund sent. Again a day later Ancheer sent an email saying "your refund is being sent". So when asking for a refund Ancheer would not respond except when Amazon got involved. In conclusion the bike is cheaply made and they have some of the worst customer services.
