BAFANG 48V 500W/750W Rear Hub Motor Kit 20"/26"/27.5"/700C Rear Wheel Electric Bike Conversion kit Ebike Conversion Kit with Optional Battery&Display

The kit was not difficult to assemble and it worked well. I made a couple of issues for myself but nothing that couldn't be fixed. I live in a hilly area and I use my bike for basic transportation so My main goal was to be able to climb these hills like they weren't there. The bottom line is that it does that and there are no issues. Reading the listing material I understood it to say that the individual gears were "adjustable" but they are not. You may select between them but there are no "adjustments" you can make. Also I picked the EKD01 display because it was blue tooth and so I figured I could use the Bafang go app. Unfortunately the only thing it would connect to is Varstom's app and it only offered maps and directions but collected and stored no info about the trip the bike or the rider and when you turn it off it forgets what was on the display. So for me the Bluetooth connectivity was useless and disappointing. Also I anticipated being able to get battery information beyond the voltage but again I am told that simply isn't posable with what I have, I got the 13AH battery. so no battery info from the bike. Also I had issues with the display from day one, beyond my disappointment It was unstable and it ultimately wouldn't turn on so it went back and they did replace it. There was customer support and they did communicate with me and like I said they did replace the display for me. All in all it works solidly and the kit seemed to be put together well. There have been some disappointments but some of that may have been my own misunderstandings, maybe.
