36V 48V 500W 750W Mid Motor Kit met Torque­sensor en Lithiumaccu

Delivery was great, only took a couple of days. The mid drive was so easy to fit, which was great because I'd never done a conversion before, but the easiest thing in the world. The torque on the drive is fantastic, pulls me up steep hills i couldn't even climb on a bike as a kid, although I haven't tried it with the throttle yet as i prefer to peddle. TIP - the manual for the display unit is on kirbebike webside, mine came with the T5S.
There was some queries around max speed and what can be expected, it depends what size cassette and wheel you have, but technical help was spot on. I did have some worries about making such a large purchase online and if it was going to be what i expected, needn't have worried, the whole process was perfect

First off the ordering and delivery were easy and quick.
It’s not the first e-bike I’ve build but it was probably the easiest. The power is good with smooth delivery. Sometimes you don’t even notice. It is a really neat piece of kit.
I do wish the battery charger was a bit better as it takes ages to charge.

I recently installed the Mid-Motor Electric Conversion Kit on my bike, and I couldn't be happier with the results. The kit was easy to install, and the instructions were clear and straightforward. The mid-motor provides an excellent balance between power and control, making my rides smoother and more enjoyable.

I noticed a significant boost in performance, especially on hilly terrains. The motor is quiet, responsive, and the battery lasts a good amount of time even with regular use. It's perfect for both daily commutes and longer cycling trips.

The build quality is top-notch, and it feels incredibly sturdy. I’m really impressed with the overall performance and would highly recommend this kit to anyone looking to upgrade their bike to an electric one. This conversion kit truly exceeded my expectations!

My first endeavour into the e-bike world in a more recent focus on improving ones health as well as desire for a new project. The performance of this mid-drive is amazing and is a breeze to install! All connections and pieces are quality! Got this kit for its torque focused motor and it really does feel more natural. The throttle is also a nice addition too for those step hills/end of a ride where your feeling knackered.

Range - Did a good test recently which came to a total of 34 miles (54km's) and most of this was done in assist 4-5 in the highest gears with a sustained speed of 20-23mph (Nice long and straight light gravel cycle route) and still had between 10-30% charge. Amazing as I am a heavy rider (currently 123kg)

Speed - Even though I am a chonky user (123kg), ones top speed achieved on a flat piece of land is 28mph, which just shows the power of this motor. So heavier people should not be put off for sure! Keeping in mind I often only go up to 20-23mph due to where I am going.

Noise - It is amazing how quiet this unit is, mostly can only hear it when going slow but this is at a soft whine. I really like how the tone changes depending on speed and use of the pedals!

So yes! Highly recommended and great value piece of kit!

Bought this to breathe new life into my 2021 Vitus Dee 3 speed nexus.Kit fitted on no issues.Performance is fantastic and especially on hills. The speed sensor needs careful fitting.Otherwise fit and enjoy.Best performance per £ on the market.

Brilliant! it's like having bionic legs!, fitted the kit a couple of days ago and I've covered sixty miles so far with no problems at all.
Installation was very easy with a few simple tools required and now cycling is fun once again! If you're looking for a pedal assist, get this one!
