  • Very satisfied overall and pleasantly surprised by how well this product works !
Overall very satisfied with this product. Was able to install this mid drive e bike motor kit in a pretty straight forward manner on my mountain bike. The kit only added about 18 pounds (8.5 kilos) of weight, so this is a definite advantage (vs. a normally much heavier standard e bike) and the performance has exceeded my expectations. Some advice - 1) check your state for e bike motor power limits. For my state, a 750W motor was the limit for a standard e bike. Get a more powerful motor (I.E: 1000 W) and you may have to register your e bike like a motorcycle 2). Watch numerous installation videos on line before you begin your installed (the written installation instructions are limited) 2) Make sure you measure the length of your frame tube holding your pedal crankset to order the correct kit ( 68 - 73 mm is standard for most bikes, but do not assume - measure it ! ). 4) Kit requires you to pick accessories. You will see this step during the check out. Recommend getting each accessory. 5) The kit contained two specialty tools needed to remove your crankset (cranks and cassette), which is nice, but one tool worked and one did not. If one of these tools does not work (I.E: the cassette removal tool) go to a bike shop and purchase a non knock off tool that works. 6) If you decide to mount your battery on a rack behind the seat (like in my pic) the wiring may not be long enough. There is a bridge wiring piece provided, but I had to purchase an additional connector from an electrician to it to make it work (the only minor hassle with the install). If you mount the battery inside the triangle of the frame (possible on most bikes, just not mine), the wiring should be plenty long enough to connect the battery to the motor. ... show more

  • If you're on the fence, just get it.
I've been on the fence on getting one of these kits to convert my bike for a while to make commuting easier. I finally bit the bullet and did it, and holy cow does it exceed my expectations. I got the BBS02, 48v, 750W kit to have it be in compliance with laws in my area for what constitutes an E-Bike. Let me tell you this thing ROCKS. The biggest issue I had with commuting was always this one particular hill that's just massively steep. Like 18% gradient steep. I could never make it up it, and always ended up pushing myself too hard, getting off to walk up it and being exhausted. I was worried whether an ebike motor would be enough for this hill, especially since I am a bigger person (~270lbs). I'll still be giving it some effort just to make it up a little quicker, but this motor will pull me up that hill in 4th gear on my bike at ~12-14 mph. It's so great to not only not be exhausted at the top, but also get up it fast enough that I'm not even struggling to maintain balance. The only downside here is there are a lot of cables. You'll want to go ahead and buy some cable wrap and zip ties to make everything clean. I used the mesh looking cable sleeve type. If you take your time and plan a little bit ahead, you can have an installation that looks really good, and the only giveaway at first glance that it's electric is the battery. I also got the shift sensor that cuts power during a shift, but opted against installing it. I just use the brake levers as a pseudo clutch to cut the power when I shift, and I honestly don't shift that much anymore as my 4th gear ratio is just about perfect for not being too hard for the motor to start from a standstill and having good traveling speeds on most of my commute. Installation was simple enough. I can't remember if I followed their directions directly or followed along with a youtube video, but it's pretty straightforward. There are tons of youtube videos out there covering this exact installation. I still ended up having to go to a bike shop for help, the original bottom bracket on my bike was on tight and I could not get it to budge with the tools I had. Once they got that off I was able to finish everything up without any further setbacks. ... show more

  • Worked as advertised, straightforward installation
I installed it on my 2010 Trek 700 so that I can have assistance on a bike with ergonomics I already know I like. Now I have tons of power to get assistance whether it's going up a gentle grade, against wind or up a steep long hill, or accelerating from a stop. Play around with the gear you use relative to the assist level to get smooth rather than intermittent assistance. I still have not figured out how the bike speed and cadence alter motor output but am getting smoother output after couple of weeks of almost daily use. It's a different feel than the previous Bosch pedal-assist bottom bracket motor that was on my cargo bike I sold--in part related to the throttle feature which leads to a brief assist on the chainwheel even after a I stop pedaling. I recommend watching a couple of different online videos to get helpful tips on installation, which went smoothly. I got the 48V750W68MM motor kit, 42T sprocket (mostly just to match what I already had on the bike), 500C display, brake levers/sensors for my old-style V-brakes, and the downtube shark battery 48V13AH. I installed the headlight that came with it too. I was hoping by getting the cheaper battery it would be smaller because I do not need a lot of storage for long distances but it's still big. To make the battery fit, I had to put it on the water bottle bolts on the downtube in the opposite orientation. The speed sensor and magnet for the rear wheel also required some time to figure out an orientation where the magnet on the spoke would not hit the sensor on the frame--must have been something about my frame. I highly recommend this kit. Everything appears to be high quality and hopefully will last a long time. ... show more

  • No customer service response
Fantastically fun motor, easy enough to install at home with provided tools. Had an issue with a cable and customer service quickly helped to solve issue.
