The wheel arrived in perfect condition. The battery didn't arrive at the same time as the wheel, so I was worried about having part of my order missing. It's only hidden away in some text that says batteries sent separately. Not worry-free but the condition of the package is fantastic.
Super fast delivery, rim and battery arrived same day at different times.
Brilliant product, loving it.
Thanks very much.
Received wheel and kit promptly 6 days after ordered, great. 15 days later and no tracking from the batteries original destination, so have no idea where it is or even if it’s coming. Image being a 14 year old kid, waiting.waiting, with no clue
Loving the Kirbebike 72V 4000W kit so far! It was easy to install and the power is insane—hits 55mph no problem. Battery range is solid too, perfect for long rides or daily commutes.
Install was easier than I expected. The power is solid — great for daily commuting and weekend rides. I'm really satisfied so far.
I recently installed the Kirbe 72V-4000W High-Power E-Bike Kit, and I’m absolutely impressed with the performance! The upgrade was straightforward and everything was well packaged, with clear instructions that made the installation process smooth and easy.
The power output is fantastic – it really gives my bike a serious boost. The 72V battery provides a long-lasting charge, and the 4000W motor delivers incredible torque and speed, making uphill climbs and rough terrain feel like a breeze. I’ve been cruising at high speeds with minimal effort, and the acceleration is quick and responsive.
The build quality of the kit is top-notch, with solid components that feel durable and well-made. I've also noticed a huge improvement in the overall ride, and the kit seems to balance power and efficiency perfectly.
I’m really enjoying the ride and highly recommend this kit to anyone looking to upgrade their e-bike for more power and performance. Kirbe has definitely delivered on their promise of high-quality performance!
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!
AMAZING! This e bike kit is awesome and puts out so much power. Very fast shipping and highly reliable, highly recommend!
First off the pas system did not fit my bike, also the break sensors do not work on hydraulic brakes, apart from that it all went together quite easily. Also had to fit the throttle on the left hand side as would not fit on the right hand side, and the on off on the right hand side.
I found kirbebikes great to do business with easy to communicate with and with a person not a machine . Great service .
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!
Quick delivery no nonsense thanks heaps
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.
The parts came early which was good for me and the sales team were very helpful when I called them , lovely to have a human being to speak to.

Hello, Friend. Thanks for your feedback. We wrote the tracking numbers in the order details. But we don't send you email about it, sorry not let you know for it. We will improve our service and will send tracking numbers to customer's email adress.
Enjoy your riding!
Very happy with purchase.great quality. Don’t buy cheap imitations stick to KIrbEbike as they are the best kits by far
All went together really well and the quality of everything seems really good. Should you need any support the guys are really quick to respond. I only had to contact them about getting the dimensions of the controller prior to my kit arriving which Jason provided in a detailed drawing.
Its damn Fast but also very smooth and quiet.
