There was a problem filtering reviews right now. Please try again later.
In summary, the kit (and battery) arrived quickly, was complete and relatively easy to install, the customer service was excellent, and the bike (Trek 3500 MTB) is great -- I'm exploring everywhere now that hills and distance are no concern.
I bought the BAFANG BBS02B 48V 750W 44T Mid Drive kit with the 17.5Ah battery and 500C color display and thumb throttle from Junstar. I chose Junstar because of the positive reviews for customer service. There are many factors to consider when choosing a kit configuration (type of motor and battery and display, programmibility, your bike's frame size, tires, brakes...it is well worth researching thoroughly. I will note just one factor: I chose the big battery because I wanted the range. However, for any size battery, if you ride on any rough road (let alone trails), I would recommend the rack mount. Batteries are very heavy.
The hardest part of the installation was deciding how to tie up the extra wiring. The pictures show my approach. My rear brake is a Shimano V-Brake which incorporates the rear shifters so I could not use the kit's brake lever. I removed the switch from the kit's brake and glued it along with a spacer (photo 8) that activates the switch. (The vendor sells a magnetic switch alternative.)
I did not like the default programming. You'll need the separate programming cable to make changes. There is a lot of discussion about configurations on the Web. The process was easy and went well. However, the throttle was very jerky. Per suggestions from the Web for a different setting, I tried but couldn't get the cable to work a second time. I tried a different PC as well as a different OS but no luck. Millie at Junstar sent me a new cable and that one did work fine. I've made a couple of throttle tweaks, which helped a little, but I rarely use the throttle.
The throttle is basically either on or off. There's a slight ramp up but it's nothing like a motorcycle control. The PAS (pedal assist) works for me: I'm always in a low enough gear that my cadence is normal or higher (protects the motor) and I set the assist level to the amount of effort I want to expend. PAS doesn't work the way you first expect it to -- you'll see plenty of comments on the Web about that -- but then you learn that it does work the way you want it to.
Lessons I learned:
- The left and right crank arms come in differently colored packaging. However, I didn't pay attention when installing and -- natch -- got them reversed.
- Going over some rough railroad tracks, the rear rack wrenched free from the horizontal mounting rods and the battery and rack fell dragging behind me. Luckily, the only damage was the scraped rack. I added hose clamps (photo 9) so that the mounts can't slide.
- I was halfway up a steep trail when my motor stopped working. I feared that I had burned it out, and I headed back, hoping that it would work again after some cooling. At the bottom and still no motor, I noticed that the connector to the display was slightly ajar. Reinserting the connector was all that was needed. (The dead display was the obvious but overlooked clue.) I added an extra zip tie (photo 10) for that connection.
My only wishes would be a more nuanced throttle control; and a blinking option for the headlight and taillight for daytime riding. Otherwise, I'm super pleased.

Still learning how the whole setup works, but it sure delivers smiles! I have taken it for only a few short rides, and it has plenty of power to really get you going. In the Trek's low gear, it allows me to climb hills that I otherwise wouldn't be able to. Battery seems to have LOTS of capacity, it's going to take me a good number of hours of riding to wear it down it appears. Need to upgrade the brakes now as I get to places where I need them!
Update 9/1/20 - I have taken the bike on a few urban trail rides here in Colorado Springs, and wow - 750W is awesome to have on tap (will peak over 1000W if needed), and the 17.5AH battery might be too much - I can barely make a dent in the capacity! Rode probably 20 miles today over a couple of hours, and the battery is still nearly full. And I wasn't shy about using the throttle. I got off it a few times to check the motor temp, and it never got more than just warm.
I'm a life-long cyclist, but I've broken both of my hips (in cycling accidents). My hips have deteriorated to the point that cycling under my own power results in a lot of pain. Using this in pedal assist mode allows me to get the benefit of the smooth, low-impact rotation without putting nearly as much strain on my joints. I live in a rural area with plenty of quiet, scenic roads, but also a lot of hills. With this setup, I can use a combination of downshifting and increasing the level of pedal assist to cruise up 10% grades almost as if it was level ground. I was a little uneasy about the purchase because the mid-drive motor required replacing my triple chainring with a single, eliminating all my granny gears. I settled on a 48 tooth in order to have a reasonably fast top speed, which also meant quite a high lowest gear. I wouldn't want to have to pedal this on my local terrain without pedal assist. With pedal assist, after changing the useless default controller profile settings, I'm finding the 48t was a good choice. I'm still learning what the range of the 13ah 48v battery is, but I think it will end up being 80-90 miles, riding as I am.
If you're considering buying one of these, my advice is to do as much research as you can in advance, including watching one or more of the numerous installation videos that are available, and make as educated a choice as you can. There are a lot of options. The installation, though fairly easy for me, still requires skill and knowledge. I've been building and overhauling bikes for years, and I have tools that most backyard mechanics aren't likely to. That said, the end product is definitely cool - like having an on-demand tailwind!

Den Einbau hat für uns jemand übernommen der schon Erfahrung damit hat. Die Leistung ist bisher super. Ich habe den Motor im Gepäckträger gewählt weil mein Rahmen zu klein gewesen wäre und ich die Optik meines Rades schön finde - da hätte mir der Akku im Rahmen nicht gefallen.
Mein Mann hat den Akku im Rahmen und wir sind beide sehr zufrieden.
