Bafang 48V 750W Electric Bike Conversion Kit Mid Drive with Chainring 44T, BBS01B Mid Motor Kit for Women Men Adults, DIY eBike Pedelec Kit C18 Display, Thumb Throttle with 13Ah Battery

Let me just say that this motor is great. It goes relatively fast (faster than a bicycle but definitely not going to go over 25 mph). But, I do have a few issues. First, it was pretty difficult to install, and even after install, my chain kept on skipping on the default chainring (thinking of upgrading the chainring currently). The documentation is far from great, and it doesn't truly go into detail. But all of this I could get over, with a little help from my local bike shop. My only issue was mid ride, it stopped turning on. After diagnosing the problem, it became clear that my controller was fried. I wasn't riding very hard, or putting any stress on the motor, probably going about 10-15 mph. This happened about 4 days after purchase. I still love the motor, but in my opinion, you'd be better off going to your local bike shop and getting a pre-built ebike from there, or ordering from the plethora of ebikes on Amazon.
