  • Top notch motor and customer service!
Color: C961 display Size: 46T & 17.5Ah Down tube Battery
Omg, this motor is amazing!! Easy conversion, found all the info I needed to install this on YouTube. The customer support was top notch (thank you Millie for prompt replies). Lessons from my build: I paid a bike shop to remove my old bottom bracket and pedals ($25 well spent, they had all of the tools, took them 10 mins). Do not try and install the shift sensor at the gear shifter, the supplied cable won’t reach it, and it doesn’t work well there, install it inline next to the back tire. I have a mountain bike, the max front chainring that I could install was 44t. Don’t try and put a 52t, it won’t fit. Buy the Bafang installation tool, unless you have a full bike tool set. My mountain bike was an Xs frame, the down tube battery mount did not fit, I had to install it on my back rack, I actually like it better back there, now I still have my water bottle cages. Do not worry about having to download any special software to use throttle only. I have the C961 controller, I can use throttle only with PS 1-9 without pedaling, or when I start pedaling I stop using the throttle and get the same speed with minimal effort. This thing goes fast! I haven’t tested the longevity of the battery charge with just using throttle compared to pedal assist, I’ll update that info later. ... show more

  • Received the older version of upgraded controller
Color: 850C color display Size: 52T Chain Ring don't include battery
UPDATE - their customer service people really went above and beyond trying to make this right for me and they did! I would definitely order from them again, Just for their excellent customer service especially with your build. **** The actual mid drive is great but this review is for the seller - junstar, I received the OLDER version of the upgraded controller from them. The current version controller on this kit should have 4 cables coming out of it (for display, battery, speed sensor and last, gear sensor plug), the unit I received only has 3. I even posted that question before ordering this kit from junstar and was told that it has the gear sensor plug built in the controller. One of the problems with this build was keeping the cables/wires neat so they don’t get in the way, instead I have to attach an additional cable from the brake cutoff plug then run it back to the rear of the bicycle for the gear sensor cable. This should’ve been a ONE star review but to be fair they shipped this expedited, they responded and admitted that this was their mistake and they will be supplying the extra cable for my gear sensor. It also could’ve been easily a FIVE star review if I received the actual product that I ordered, just very disappointed for now. ... show more

  • Amazing kit
I did a lot of research and decided on this kit. All parts were in the kit and really high quality. The install went without a hitch. I did watch dozens of YouTube videos for help. The hardest part was taking of my old bottom bracket. It would be great if the kit added the wrench to do that. I had to buy the wrench and another socket to remove my old stuff. I have only put about 50 miles on this motor so far, but so far so good. The brakes handles work great disengaging the motor when pressed. The kit doesn’t come with the gear sensor, so I bought that separately. I recommend buying one as it disengages the motor when you change gears. This motor makes going uphills very easy. I love going up a hill at19 mph. It makes riding my old 2004 Gary Fisher Tasahara fun again. I have been up to 31 mph down hills. That is fast enough. I good cruising speed is about 20 on flat ground. I got the 46 tooth front sprocket so that it is better for trail riding and not max speed for commuting. My 27 speed bike is now a 9 speed but that is fine. I’ve only ridden on the road so far, as winter weather set in, but it is plenty fast enough. Also, don’t think you have to have disk brakes. I don’t have them and can stop fine. I look forward to riding some trails in the spring. Hopefully, this motor will hold up for a long time. As far as this seller goes, I was surprised at how fast this was shipped to me. I think I received it only 4 or 5 days after I placed the order and it was well packed in a really small box. At first, I thought there was no way the whole kit could be in there, but everything was and in good shape. Highly recommend this seller. Great kit! ... show more

  • My new commuter
Color: 750C color display Size: 48T Chain Ring don't include battery
I needed a new commuter bike. so I started with 26" MTB and the 750W Bafang. great little motor, with all the power I need. My knees are not what they use to be and the PAS is just great. Installation was straight forward and simple, about a hour and half.
