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.

photos and video to follow shorly

Fantastic

Just great guys. Will highly recommend

Thanks for a really quality product ✨️ 👍🏻

Worry-Free Purchase

New controller

Had the controller verified that that was the issue, damaged by my son. Quoted and sent straight away. Top class performance

Great kit

A little delay before the assistance kicks in but I’m happy I made this purchase. You can pedal hard if you want to reach top speed and actually still use your legs, or just use the throttle if you feeling Lazy. Really easy to install even easier to use. Now I wish it was 1000w

Problem with order

Unfortunately my order had a problem. My wheel kit arrived with the standard wheel instead of the MTX wheel as advertised. I contacted the company who were very reluctant to exchange it and told me I would have to pay some of the return costs. I was offered a £50 pound refund and one year extended warranty for keeping the wheel I had. I endered up excepting this due to the expense and hassle of getting it changed.
So the buying experience was not as good as I expected,. Sorry about the negativity but you did ask. Regards Paul.

Great kit to convert your bike in e-bike

48v 750watt

Very happy so far kit was very easy to fit took around 2 hrs. The only thing was the digital display t5s the manual is very confusing but after a few emails I managed to figure it out.only negative should review t5s instructions. Looking forward to many gravel rides. Thanks again very good kit at a good price Mr Steve Horsfall

My new 2kw kit

Excellent product easy to fit done 200nmile in last week coupleof small problems but looking to upgrade battery to 72v or 60 v and controller gett more acceleration&torque slight problem battery voltage sag but emailed regarding my problems having need surron throttle and display settings list of what's what they do as no instructions is italways normal yo have red indicatorlight on a full charge

its good idk what to say but its good

for me 20ah wasnt enough, so instead of going to another supplier, i might as well get another battery and run my bike in dual battery, 40ah of hotness

better then they even say!

it took about 1h 30 with no experience and charging was not 4 hours it took about 2, top speed is also 95 mph plus with no weight. amazing kit

Brilliant

I was shocked of how good this actually was. It’s a great buy. People were all very friendly and helpful as I had no idea about anything and they helped me along the way

Motor and kit excellent the crank arms are of questionable quality

Crank arms stripped within 10 miles of cycling re tapped and used a threaded insert to repair and that stripped out after 2 miles the crank arms atleast one of mines appears to be incredibly poor quality metal, replacement cranks aren’t that easy to source either. May be worth kirbie e bike trying to contact tongshen tsdz8 manufacturers and seeing if a revision can be made to the crank as I don’t seem to be the only person with this issue.

Can’t fault kirbie e bike and I’ve sourced another crank set hopefully this will get me going again

fantastic

takes some time but resuts are worth it
I found Kona tourqe arms were visually better than those supplyed as they worked with my bike frame better.
take your time and be safe riding

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.
