I'm new to e-bikes. I purchased an ancheer mountain bike in september for a couple of hunts I had upcoming. it worked great using it around the house and the first hunt went good except that toward the end of the hunt i would be going along and it would stop assisting for just a second or two. After I got home I rode it a few times and the cutting out was rare. This last week I took it to the second hunt and 15 minutes into the hunt it quit completely and it will not work at all now. I've contacted the company I purchased it from off of e-bay but they just ignore me so I'm left figuring out what might be wrong, how to test and where to by the parts. I'm just looking for information so that I can learn it and fix the issue. All information is appreciated.
