Great kit but I would like there to be more torque
Long story short this has been hella amazing, I thought this would be situation of “ts pmo this gon take 3 months 💔 🌾🌾🌾” but actually the shipping and such was pretty reasonable, over all it took around a 2 weeks for the motor to arrive and another week for the battery if I’m not wrong.
The installation time on the website is pretty much a ‘professional estimation’ 😭 for me atleast I had to put some steel to make the battery fit but even without that, it took around a full days worth of getting everything on, could be that I am still an amateur at this but you’re mileage may vary.
When I was don’t, god damn from a 250w motor going 40kmh with little to no torque, to this absolute beauty of a kit is crazy like I had to go to the advanced settings and change the PAS from 5 to 9 and throttle strength from 5 to 2 becuase it just has so much god damn power right off the line. I have managed to reach 91kmh with the wind on this kit, I weigh 65kg and the bike without kit is 35kg, but is wear this was worth every single euro.
Last note is that the response time of customer service was like 9/10, it may take at most 2-3 days for them to answer but on average it was a couple of hours, this may be the only time that i have ever left a review but customer service was top notch, whenever i ask for the status of the battery or motor, they provide tracking information for you and for technical information, Jason really helped me a lot 🙏
Great kit. Pretty simple to fit with a couple of adaptations here and there. Im a big fella and this gets to 40mph on the flat. (40mph on a hardtail mtb is scary fast)
Customer support is great, i was worried because the battery wasn’t delivered with the kit but it arrived next day with a different courier which was quickly explained to me via email.
Definitely purchase a pack of 10mm wide cable ties though, i feel like the ones provided are a bit on the light side if you plan on hitting gravel paths etc.
I'll start by saying that I didn't actually buy my kit from kirbebike as I had it gifted to me, but this little motor is amazing. The install process is a piece of cake (unless your bottom bracket has seized, which mine had). This kit makes riding pretty much effortless, I've hit 31.8 mph on flat ground using only a 7 speed casette. The motor is quite and makes hills seem like your running over a mole hill. I'm writing this review on kirbebike as I'm a fan and supporter of Andys YouTube as well as his products, good quality stuff and Jason always provides great customer services.
Fitted the extreme motor fat tire 20x4 kit to my Super73zx and it's bloody marvellous' so fast and so much fun to be had' Super73 use there own unique torque arms so some modification is needed but the dropouts length of 190mm is the correct size and 175mm is to small so don't make that mistake if considering other kits.
Great kit and delivery was within a week with full tracking provided.
I'm 52 carrying a bit of midlife weight and the doctor has told me to start looking after myself. So I bought a bike. I live two miles away from my workplace. Now as I work at a large vehicle manufacturing plant getting out of the car park is a nightmare. Not anymore. I decided to fit a kirbebike kit to my hybrid trek bike.Im home before most people have even got out of the car park. The kirbebike kit has honestly changed my life. I pedal as much as I can but when I need that little or big assistance it's there. FANTASTIC thankyou you have changed my life.
Excellent kit . Fitted perfectly on my bike and hits over 40 mph. One of the quitest kits i have ever bought. Very happy with the purchase.
The bike i built with the 4000w motor is great, easy to install and amazing performance. I emailed customer support for any questions and all theyve gave is help, i couldnt have bought a motor from a better place, theyve been quick to respond and very very helpful. Thank you kirbebike for this amazing kit!!!
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
Very good service. Jason is a superstar Delivered within 3-4 working days. Communication is excellent. This is our 8th kit. Very satisfied with Jason’s kits.
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 /

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!
