This came so quick and reliable and i love it its so fun any freebies would be appreciated ive recommend you too alot of my freinds

Return policy

The kit was not compatible with my bike and the customer service has been great with helping me trying to get it to work however, I am wanting to make a return now and I have been waiting a while to be connected to the shipping department

2000watt kit

Honestly where do I start the kit itself is the best quality and has the clearest instruction manual on how to install and any help I did need was answered by Jason in a timely professional manner absolutely pleased with my kit and the 40mph I get all day long

Good quality so far

Ordered the kit and my bike is not compatible :/. However the kit seems to be good quality and the customer support has been great with helping me with the kit!

Very good kit easy to fit I’m pretty satisfied thank you

EZ Rider kit for commuter bike

This kit is absolutely brilliant! I did 3,500km on mine in 2 years.

I use my bike to get to the train station, which is 6km away from my home. There is a massive climb on the way back, which is not what I want to deal with after a day at work. I was looking for a compact electric kit to put on my bike, and EZ Rider was ideal. It was shipped quickly, no pre-order wait time like with the alternative one. I really like that the battery is easy to remove and compact enough to throw in a backpack. I just lock the bike, take of the battery and get on the train.

That's commuting, what about longer rides? Weekends - I cycle with my 2yo in a child seat. For its size the battery holds quite a lot of power. I get 20-30km from a full charge depending on the terrain with assist at 2 and 3. I also got a second battery, that I carry in a bag on long rides, which gives me 50-60km range. So, it might be not very obvious, but having a swappable compact battery gives you flexibility. If it was one big battery - it wouldn't be ideal for commuting/shopping - carrying a massive battery in a backpack. I you want to use the bike for long rides - just get a second battery!

Really smooth

The kit is quite and easy to install, goes faster than what the site saids and is a beast. With no ebike experience i installed this in 3 hours.

Great battery

Had this battery on my mid drive and did good mileage, did have problems with my motor, but kirbebike have since fixed for me.

Pleasantly surprised

I had low expectations not for the e-bike kit but for anything that’s road legal in the uk! This kit massively exceeded my expectations. Easy to fit, easy to set up and has changed my 3.5 mile Devon hills commute from an arduous hilly 25mins to an 11 minute leisure ride. I don’t expect it’ll be long before I swap out for a higher wattage kit either 1000w rear wheel or mid drive.

ebike kit

kits solid, battery and screen dont say the same % and i emailed yous a few days ago with a problem and got no reply, fixed the issue my self

Easy to use

Used as it was cheap and the reviews were good

Highly recommend

I bought my 2000w 52v kit last year, its been great used it daily any problems or queries have been met i highly recommend

Excellent kit

Very good kit, you might need to find a few spacers to make a perfect fit. Very good all bolts come with thread lock (a nice touch I thought). I do 23km ride on level one assist (live in a hilly area) and battery on 80% when I finish which is good I think

No installation instructions

1st time installing kit, no instructions of any use, disappointed no lead lamp plug in have to buy their lights kit, email queries replied but without any real help to be honest pas sender only viable tied on very poor dash is the cheapest of cheap all in all won't buy from here again

Spot on !

Very pleased with everything, ordered this late Thursday night and it came on the Monday, then the battery a few days later, very easy to install thanks to YouTube dude stuff, this is a game changer, highly recommended this product and kirbebike, thank you 😁

1000w

very good kit , a little slower than expected

Kirbebike's 500W and 750W MTX Rim Ebike Conversion Kits

Really good stuff easy to put together and fun

48v 750w mid motor torque censored with lithium battery pack

Wow! What an awesome bit of kit. Well worth the little extra paid for the 750w. Arrived promptly and as described. Very easy to fit for me being mechanically minded. I didn't fit the throttle as I don't think it's needed with a peddle assist, it gives the ride a more natural feel. I had no issues at all fitting the kit, didn't even need a new chain. I also like the fact I can choose the level of assist I need and with the rear gears at my disposal it's so good at beating those hills. If you're thinking of converting your cycle to an ebike, thus is definitely the kit for you.

Kirbebike's 72V 4000W Extreme Performance Ebike Motor Kit for MTB and Fat Tire Bike 55MPH+

This kit is fast! Long lasting battery with plenty of power. This kit is an easy clean install! Great technical support group will answer all of your questions.

52v 2000w Kit Review

Good reliable kit, came quickly, all working, setup was rather easy. Would 100% reccomend to other users

Good Product

I might as well get another battery and run my bike in dual battery, 40ah of hotness also by using GrabOn coupon code I got best discount

👍's up (:-)

I fitted the kit to my Raleigh Stowaway though the cable to the display, brake levers, thumb throttle isn't quite long enough and the motor cable is around a foot too long. I had a display cable from another build and found a motor cable on ebay that was the perfect length. I like that they give you a choice of two types of cadence sensors. The controller is a 36/48v 17ah and it comes locked to 15.5mph, unlocked 21.4mph

A Business as personal as your bike

Jason at Kirbebike has been great from start to finish with my experience of the products and service I have received.

Products and Services go wrong all the time and it's the response of the people behind the company that help determing the experience a consumer remembers. If you have an issue, just get in touch first.

Products arrived well packed and in good time. I've returned to Kirkebike for further products.

Your bike is personal to you and if you want an electric conversion to help to go that extra mile, then speak to Kirbebike.

Voices of Our Happy Customers

first ride shock total beast!

Took the latest build out tonight and it’s an absolute beast. The 72V 4000W KirbEbike kit installed cleanly, and despite the extra work to adapt suspension on a BMX, everything aligned well. Throttle is responsive, wheelies come easily, and tracking stays stable at speed. I’ll be swapping to more BMX-style pedals and a new seat shortly. No odd noises, no heat fade, and wiring stayed tidy. I’ll shoot a video and proper photos soon. Overall, very impressed so far.

80% done looks insane!

Kit arrived quickly and well packaged from KirbEbike. Straight-forward install on the C100 v2 with a 60A sine controller and 72V 20Ah battery. The 19” 3000W wheelset with Kenda 26×3.0/2.75 tires went on cleanly, and the KKE dual-crown forks feel planted. Deity riser bars, Renthal stem, and Hope headset lined up perfectly. Short shakedown ride pulled hard with smooth throttle response. Still need a few cable tidies, the front brake, and purple decals. Overall, very promising.

bmx rocket wheelies on demand!

Build came together fast and arrived well packed. The 72V 4000W KirbEbike kit dropped into the BMX frame without drama, and upgrades since test rides made a real difference. Acceleration is ridiculous yet controllable, and front 4-piston 203mm hydraulic brake bites hard. Rear v-brake with fresh triple-compound pads is dialed and surprisingly effective. Frame feels tight, wiring is tidy, and the display is clear. Took it on a mixed urban loop—no heat issues, no rattles. Overall, thrilled with it.

another 2kw tidy finish!

Wrapped a second 2000W KirbEbike conversion for my brother and the result is tidy. Delivery was fast, packaging secure, and all parts accounted for. Install needed patience around cable guides, but the motor dropped in smoothly and aligned well. First shake-down over paths and light trails was quiet with strong pickup. Brakes bedded quickly, and the harness tucked away neatly under panels. A couple of cosmetic tweaks left, yet the core setup feels dialed. Very satisfied with how it turned out.

city flyer silky and quick!

Another 2000W 52V setup completed and I’m really pleased. The kit came well packaged with clear instructions. Axle seating and cable routing were easy, and the wheel was true out of the box. On a 15-mile city loop, acceleration was crisp and cruising effortless, with stable braking and no controller heat-soak. Display remained readable in bright sun, and battery estimation matched my log. Cheers to Andy and everyone for the solid support and quick replies. Overall, excellent value.

commute crusher winter ready!

Just wrapped a 2500–3000W, 60V 20Ah build for my daily 18-mile round-trip. Kit arrived quickly and was very well packaged. Installation was straightforward with clear labeling, and the motor seated perfectly in the dropouts. First rides over cold mornings and damp roads were smooth, with strong mid-range torque for hills. Regen felt natural, and the display is easy to read with gloves. Battery management looks solid so far. Support from the KirbEbike team has been absolutely class. Really happy.

triple threat three 1500w rigs!

Wanted to share three SCS builds: all 1500W 48V, with 36Ah, 18Ah, and 20Ah packs. Kits arrived quickly, labeling was clear, and everything was well protected. Each frame had minor differences, yet motors seated easily and controllers tucked away neatly. Test loops showed consistent performance across capacities: the big pack cruises longest, the smaller packs keep things light and lively. Displays matched expected voltages, and braking remained stable. Zero wiring gremlins so far. Overall, three tidy installs I’m proud of.

fits like a glove love it!

Love it, guys. Kit fits like a glove and the install was genuinely simple. Packaging was solid, all fasteners were present, and harness lengths felt just right. First rides showed a smooth, quiet motor with plenty of go for city hills. The display is bright, throttle is progressive, and cable runs look factory once tidied. No error codes, no rubbing, and no unexpected noises. Customer service was spot-on and friendly. Overall, very happy with the performance and the experience.

52v 2000w punchy and smooth!

Well happy with this 2000W 52V kit. Shipping was quick, and everything arrived in perfect condition. Install was straightforward; torque arms and spacing lined up first try. Took it over a mixed route with short climbs and rough tarmac—pulled hard without overheating, and stayed quiet. Display metrics are clear, and the throttle response feels precise at low speed. Post-ride check showed all fixings tight and wiring tidy. Big thanks to Andy and the team for the help. Great result.

roll 2.0 almost done!

Project almost completed on a Specialized Low Entry Roll 2.0. Running a 52V 25Ah pack, KirbEbike 2000W motor, Shimano HD brakes (203mm/180mm), and Maxxis Hookworms. Controller is a Flipsky 75200 Pro V2 with EVPW VESC display; added Statorade to keep temps down. At 185 lbs I’m seeing a true 35–38 mph on flat. Install was neat, wiring is secure, and thermal behavior is stable. Just waiting on a 72V 20Ah battery to finish the build. Very pleased so far.

brother’s build clean and mean!

Another KirbEbike 2000W conversion completed, this time for my brother. Parts arrived fast and safely packed. Install took a bit longer due to older cable routing, but the kit itself went in without fuss. First road and trail checks were smooth, with strong pull out of corners and predictable braking. Display and throttle calibration were simple, and the wheel build feels solid. A few finishing touches left on cable tidies and guards, but the result is clean. Happy with the end product.

72v 3kw rock solid might sell!

Just finished a 72V 3kW build using KirbEbike components and it came out great. Shipping was quick, packing was careful, and install was direct with no surprises. First rides showed strong torque, quiet operation, and a steady display readout. Braking and handling feel balanced, and the wiring is tidy after a final loom wrap. No heat issues on hills, and range meets expectations. I may let this one go to a new home, but performance-wise I’m genuinely impressed.

fast delivery, great product

I recently assembled this kit with a bit of trial and error, but I got there in the end. It works great and is a lot of fun to ride. Just a heads-up—you might not get all the necessary tools in the kit. I had to purchase a chain whip tool and a star bolt tool separately. I’d also recommend installing custom torque arms that screw into the frame, and a bit of Loctite wouldn’t hurt either. Overall, it's a great kit that provides pretty much everything you need to get started.

excellent, product and easy to install

The product looks and performs great. Very easy to install. I found YouTube videos easier than the paper instructions though.

love my kirbebike

Fast and trouble free delivery, installation took a couple of hours and was pretty straightforward and hassle free.
I get a huge grin on when approaching the inclines as my bike now powers up them with ease, quite something as I’m usually crawling up them, this kit has made my commute to work an absolute joy, and now find myself just getting the bike out for a spin, brilliant kit guys!!

a great shopping experience

I think for starters, I’m very very impressed with your kit and your attention to detail.
I like how everything is included. The tool kit was a excellent touch and the parts that you have included seems well thought out.

brilliant service

Once item was shipped it was here within days. Flew non stop from start to finish. Email a few times and got replies with satisfactory responses within hours of emailing too which was great. Kit looks decent as well and good quality can’t wait to get it on the bike.

great kit i recommend

Very fast and easy to fit. Had a few small problems but Jason sorted me out straight away Thanks to Jason. I recommend.

kirbe bike conversion kit

Fantastic service and what a great kit!! It was really easy to install and fabulous performance just need to ensure that your bike can cope with the speeds the power from this kit will kick out. Also the customer service team especially Jason and Charles were extremely helpful and friendly. They always replied quickly and nothing was too much trouble.
Great product sold by a great company with an amazing customer service team. I’d give ten stars if I could

awesome bit of kit!! perfect service!

Kit was a bit difficult to fit but only because the dropout spacing on my (old) bike was so narrow. Got it to fit in the end and it definately exceeded expectations. After service has been brilliant and store has been very responsive over email. Will likely buy from again in future. Thanks KirbEbike!!

definitely recommend

The bike goes like a rocket ,great communication and tracking provided, wouldn't hesitate to buy again.

excellent product

Would be silly to read this comment and not buy the product. Top quality.

secure locks with 

I completed the installation somewhat clumsily with the patient help of customer support. My problem stemmed from a misunderstanding of the width of my bottom bracket. Anyway, once I got everything working, the mid-motor system performed very well.

great communication

Very powerful combination.The seller has great communication and shipped quickly.
