Putting a rear tire on an ebike is a beating any day. I read all the reviews about sidewall blow outs and I've had that happen to me before and I found it to be how I was installing the tire so I changed how I did the job. You have to make sure its even all the way around on both sides. I do that by blowing the tire up with it off the bike. Just a little at first and then push the tire into the rim all the way around both sides while looking for unevenness .Where there is unevenness I hammer hand it to help it along and bounce it and roll it around on my work surface. When it looks even all the way around on both sides I add more air. Once I had to let air out and repeat the process but eventually the tire seated into the rim. I reassembled my ebike, which is a sondors x fold and have ridden 50 miles so far with no problems. The tire fits perfect and I hope it last as long as my last one about 2500 miles.
