8fun Bafang BBS03/BBSHD Lastest Model 48V 1000W Ebike Electric Bicycle Motor Mid Drive Electric Bike Conversion Kit

very quiet, fantastic after the needed program cable. Throw the supplied crank arms in the recycle can if you plan to ride it hard. A shift sensor is a needed addition as well.

So far 250 KM trip... and still working well,... from home to my work is about 5.8Kms, and it takes me 13 Minutes, the maximum speed I reached is 47KM/H and the average is about 25 KM/H,,, I noticed that it has lost some power if I compare from the very beginning when I started to use it, but honestly for 800Bucks is not that bad, fair enough for me, If you are very beginner in ebikes, I suggest it to you, the installation is quite easy, foolish proof, I only suggest just patience and double check the dimensions what you need before proceeding with the purchase, in the internet (youtube) you can find many instructions... I would buy one more for my wife! I I promise I will add a video when I reach 500 trip to update the review (if amazon allows me) ...

Seller 5 stars, kit 4 starsTook me a little while to get the kit installed on my first bike, and from the get go I started having speedo issues. Apparently this is a common problem where you have to mount the sensor just right. After my first failed ride, the speedo sensor died completely and would not register at all. Junstar jumped on the case, had me ship the kit to their repair center and I got the issue resolved. I reinstalled it into my road bike since and its been working great.Now for the kit itself. First off, this thing is HEAVY. The combination of the motor and battery is way heavier than I expected. It is what it is, but I was taken by surprise. With the assist levels on, you don't really feel it, but if you turn off assist, pedaling the bike becomes WAY harder. The motor sitting on the pedals also feels very strange. You can definitely feel how it pulls and it just takes some time to get used to that feeling. Moving the bike backwards is also jarring as the motor will fight you. Now the power of his drive is AWESOME. Im a big guy (280lbs) and I've had no problems going up huge hills with minor input. If anything it makes my ride too easy.The one down side of the kit is the way it mounts to the frame. The drive just slides into the bottom bracket and is supposed to just be held in place by tightening the bracket nuts on, but this is crap. Within 10 seconds it will come loose and will just dangle off the frame. I took a large hose clamp, cut it in the middle and attached the ends to the sides of the motor and tied the whole assembly to my frame. This keeps it fairly stationary, but its shitty that they haven't come up with an out of the box solution. This is why the kit loses one star.Overall its great for what I need and Im happy with my purchase.

Powerful motor even on very steep knarly mountain bike trails. Riding over rock gardens was a breeze, just make sure you shift on the right gear before you go through the technical area. I usually have the power level assist set at 3 o 4 so not to overpower it when going through slow technical climbs or rock gardens. The Power level can go up to 9...but 5 is the highest I've used it on steep climbs. Having a good suspension helps go through tough obstacles...I only use 6 - 9 power level assist on a very long flat off road trails, but I very rarely use power level over 5.I have bad knees, 2 surgeries on both. I only use my ebike to have fun and help me strengthen my leg muscles. I highly recommend this BBSHD motor.

Awesome product. Makes a cheap bicycle into a great road machine. I am an older rider (74) and lack the stamina of the younger flatbellies who one sees riding their bikes. So, the reserve power helps me up the harder hills and ensures I actually get where I’m heading. Quiet and smooth shifts, both mechanical and electrical. The only reason for four stars vs five is the kludgy wiring one ends up with.

All I can say is wow installed this kit on my new bicycle very easy to install no problems with it this thing runs excellent and it is very powerful had one problem with the monitor contacted these guys they have excellent customer service they responded right back to me probably within a half an hour to an hour took care of the problem highly recommend this motor this thing we'll climb any Hill that I've attempted to climb with no problem plenty of power I am using a 52 volt battery thank you for the excellent customer service

Installed this on a Giant 26" commuter type bike with the 17ah battery. Works phenomenally well for this purpose and I cant be more happy so far with the performance and ease of installation. The shift sensor is very helpful, so that is more than recommended. I am riding 20 miles round trip to work and it handles that easily without needing a charge (350ft elevation change to and from work, so the trip home is up hill a lot). Going up hill it can maintain ~20mph in a decent gear (6th gear of 7 speed rear cassette) and hits 30mph+ on flat, both with a decent pedal just to not drain the battery too much. Google says bike commute for me is 45-50min one way for that 10 miles, and I've done it consistently in 30-35min depending on how much I want to pedal or headwind etc.

Nice e bike upgrade.I tried other e bikes. They are wimpy and expensive.This will get you up any hill.You will be impressed.....Ask for a wire diagram. Makes install easyer....
