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
Great company to deal with, no issues. Everything arrived as communcated. Set up was easy and instructions perfect. Thumbs up.
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.
72v4000w kit relatively easy installation. All components seem to be solid and durable.
750watt Kit arrived in about 4 days battery came first and the kit arrived about 1.5 hours later,was well packed.kit quality is good and pretty straightforward to fit,the motor is quick and responsive and I managed a top speed of 34 mph so very impressed so far,the kit looks great on my bike:)
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.
Unbelievable bit of kit. I use mine for off road and I'm very impressed with the power and the speed. Great buy and great fun.
Thankyou Andy / Jason / Steve
There was only one company I was going to purchase my 2000w conversation kit from having followed Andy ( Kirbike ) and Steve ( Dudestuff ) watching all their factual informative YouTube conversions with the exact kit I had delivered incredibly quickly ( 3 days by DHL ) with updates at every stage amazing
Jason must be the Tech expert as every question I asked he responded In hours before and after safe delivery I actually think he doesn’t sleep !!
He is a Top Top Guy who knows his stuff
I brought an unbranded kit 2 years ago from Amazon and yep it worked however this Kirbike kit is completely different level in every way with its MTX rim / Motor / Sinewave Controller / dashboard screen / Wiring quality / plus Pas and brake levers and all sensors /
The 52 v 20 amph LG celled Battery is incredible / complete tool kit and easy detailed instructions
Absolutely delighted and so glad to 100 per cent recommended to other people looking for top quality products and incredible company customer service
Thankyou Guys Respect

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.
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!
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.
Ordered the Tongsheng TSDZ8 mid drive kit with 16AH battery.Arrived quickly to look Ireland,no issues.Great kit,priced competitively and well packaged.Thanks KirbEbike.Superb service throughout.
Delivery was quick and communication via emails was very good
