First class unit and the service from the team is absolutely brilliant
Range fantastic, providing you put a little of your own effort in.
Easy to fit.
Didn't fit the brake sensors as the motor cuts out as soon as you stop peddling.
Didn't fit the throttle either because of the UK regulations.
Removed my crank to fit the permanent pedal assist.
The battery/control unit is quite light.
The wheel is a good strong wheel but it is quite heavy.
Overall the kit is outstanding, and for me it's a much better choice than the big heavy batteries that you fit to your frame.
Would recommend.
Amazing customer service. Helped me understand and install my kit. Bought two I have nothing bad to say about the kit.
Really great quality, customer service is really good too.
Really impressed with it all apart from the throttle but I don't think it's designed to be used as a throttle on its own as the motor can't handle the load on its own. But the peddle assist is fantastic and battery life is great. It's a tidy kit that comes packaged well and pretty simple to fit despite no instructions.
I had to contact for support as the display also came with no instructions but got sent a pdf of these later. The only thing that you'll most likely need is a new chain as you'll likely need a longer one.
Fair is fair very happy with the kit all is good quality highly recommend
My first order came fine but I'm still waiting on my second order from the 30th of may
It’s a good bit of kit but the battery isn’t very secure in its holder infact my sons one came flying out while he was riding his bike so now the battery is all scuffed
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.
