  • Not the best fit in the tube
The majority of the install was pretty simple. Plenty YouTube videos to follow. My complaint is the kit I purchased says it fits the 73mm tube. While it does technically fit, I would not say very well. Installing into a 73mm tube leaves few teeth for the final cap to grab on to when installing. But my biggest complaint is that the right side pedal crank is spaced properly from the lower bike frame arm. However the left crank misses the lower frame arm by about 1/8th of an inch. This gets on my OCD's nerves..... Apart from that, it pushes my fat @ss around (750 motor) no problem. I purchased a 20 amp hour 48v. Without pedal assist, I can hit 30 mph on straight land and no wind. With pedal assist I have seen 36 mph. After converting my Trek hard tail mountain bike, I have the cost of this kit (750c display, 750 watt motor) and a pricey 20Ah battery pack, I am in for a little over 1,100 dollars just for this kit and battery. I could have purchased a new bike, and let someone else do all the work for near the same price. Unless you are just bored and love tinkering (also make sure you have all the correct tools), I personally would just buy a bike and be done with it. The kit came with a crank arm puller, however you still may need the socket for removing the cranks shaft from the tube. Thanks to a local bike shop, I paid them 10 dollars to remove the cranks shaft. Also, apparently the old speed sensor used a flat head screw driver, the speed sensor that arrived with my kit came with a SECURITY star bit. Good thing I happened to have a security star bit set, or that is another tool I would have had to purchase. Security star bits have a metal dimple in the middle. Real pain if you have to purchase a security star wrench set just for this install. Oh, not near enough zip ties either. I had to use plenty of my own. ... show more

  • Powerful Motor Easy assembly Bad display.
Color: Display 850C Size: 48V 750W+44T Chainring(No Battery)
Very Powerful and fast, I was able to make it run for 35 minutes non stop on full throttle with one Dewalt flex volt battery. The speed sensor that was supposed to come with it was missing. Sometimes The motor and the screen shut off while you are using it, I have no idea why that happens. Other that I have no complaint. Over all a very nice motor. The 750w motor can go around 38 to 45 mph according to bafang. since they did not give me a speed sensor I have no idea how fast it can really go. They also gave me a head lamp to mount on the front of the bike. I connected all of the wires just to find that they had given me a light and a way to hook it up but no way to turn it on! That was too bad. So over all nice motor bad speed monitor screen and they did not send me a way to turn the headlight on. So that was how it got 4 stars. if they would have given me a speed sensor and a way to turn the head lamp on, it would have gotten five stars. ... show more

  • Works well and seems quite powerful!
Color: Display 850C Size: 48V 750W+46T Chainring(No Battery)
The install went well, but wasnt without issue. I would have given it 5 stars if there was better instructions. Also, some of the cables needed to be alot longer, especially the battery cable. The gauge of wire seems a little small in my opinion but I havent had issues yet. Assuming you are able to get your old crank and bottom brackets off, the install was pretty straight forward. The bolts provided seems pretty low quality and seemed like they would strip very easy, so dont hulk them when you install it like the bolts you took off were. I hope they dont snap under heavy use. The motor itself is pretty heavy and seems well built. The brake handles feel fine. I only used the front one since im keeping my gears in the rear. I am only able to use 7 of the 8 gears I have, I believe its due to the placement of the drive gear. But thats not a big deal. I built a 13s5p battery using Panasonic NCR18650PF batteries (14.5AH) and I drove this around one assist level 1 for 10km on small hills and mostly flat areas and it drained the battery about 95wh. I tested the level 5 assist and it goes pretty fast. You dont have to pedal at all really. I am 6'2" 285, and I was pulling a 50lb bike trailer during this test and I didnt feel like I needed to use anything more than assist 1. I averaged between 10-15kph before the motor would kick on and off. I tested the max speed of the motor with no load on a lift, and in my final drive gear, it almost hit 60kph. (according to the speedometer.) The fasted I went was about 25kph. I would say that overall this is a good kit. Time will tell if the quality will last. But I do think the mid drive is worth the money of the in wheel motors. ... show more
