I have used a couple of hub motors(9 Continent units), both in front and rear wheels. The Bafang is my first center drive unit. I have a Bafang BB02, 36 volt, 500 Watt unit. The instalation is simple as pie, remove the crank unit and slide in the Bafang geared motor-crank unit, clamp it in place, add the crank arms, your pedals, do the simple wiring(the motor controller is in the motor housing), add the supplied brake levers, the computer unit, and the throttle and off you go. The throttle is touchy, it almost feels on-off at first, but with some practice, you soon learn to use it gently to control speed. After the frame on my green e-bike cracked, I transferred the unit to the red bike. The front shifter can't be used, as there is only one sprocket in the unit and there really isn't room for another one, or two, you also need the room on the bars for the throttle, etc. The seven speeds on the rear were plenty adequate with the power available. There are three levels of assist. Level 1 is good for riding on busy trails with bikes, walkers, skaters, and so on sharing the path. I rarely use level 2. Level 3 is the highest, and fastest, great for traveling alone on the side of the road.
The first time I took off using the throttle and the acceleration was much faster than the hub motors, direct or geared. It felt much quicker accelerating than any other motored bike I've tried, gas or electric. Shifting up through the 7 speeds of the rear gears was great, up to the governed 19 MPH top speed, then it just seemed slow. I went back to the on-line site with instructions for the computer and discovered how to over-ride the governor. Top speed on the throttle is now 27 MPH. Acceleration is hot and top speed is fine, what more could you ask?
I then discovered that if you turn on the power, but don't touch the throttle, you get an assist as you pedal. I use the assist when I am riding in a group, like Critical Mass. Using the assist and pedaling, I can pedal 10 or 15 times further than pedaling without assist. My bad knees normally crap out after 5 or 6 miles of pedaling. With assist, I can stay with the group as far as they wish to travel and my knees will still allow me to walk the next day. One problem with the assist mode is the power stays on for a second or so after you stop pedaling. It can be a little scary if you need to slow quickly, but the brake levers cut power whenever you squeeze them, even lightly, and you soon adapt.
Range using WOT is about 2/3 of what I was getting using a direct drive hub motor. The price I pay for the greatly increased performance. Using the assist mode while pedaling, I haven't reached the end of the battery. The range is very long on assisted pedaling and I may never reach the end.
I think this is the best e-bike I have had to date. Using the throttle only gives outstanding performance and the range pedaling in the assist mode is great. You can also simply use the bike as a pedal bike. The motor does add some drag, but less than a hub motor. The Bafang center drive unit weighs a tad more than a geared hub motor, but less than a direct drive hub motor. I am very satisfied. Four stars.
