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.

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

Quick delivery on first part of the package but too long to wait for the battery to come.

Top but of kut

Very impressed thank you.

Kit arrived on time,battery arrived later.This is my fourth e-bike kit,very impressed
With the power.I would appreciate more info on the controller connections,ie what is the shorting link for.

Ordered the 52v conversion kit and came in just a few days battery came first and then the hub wheel but took less then an hour to fully put together all went smoothly and when I needed help they answered me and helped me straight definitely recommend this website suck a good kit and a good team

Shop app would not update did not know it had been sent till it arrived on doorstep

Very happy with purchase.great quality. Don’t buy cheap imitations stick to KIrbEbike as they are the best kits by far

All went together really well and the quality of everything seems really good. Should you need any support the guys are really quick to respond. I only had to contact them about getting the dimensions of the controller prior to my kit arriving which Jason provided in a detailed drawing.

Its damn Fast but also very smooth and quiet.

first of all the kit was been very reliable for the 3 months i've had it, and the customer service it's the best i have ever seen, they sent me free parts and always listen to me and always go over the top, special thanks to jason he is the best. the range it's good but i recommend the 30ah battery for sure... top speed for me was 40mph but it will do more. torque is great as well, you can wheelie it too but it's a little harder, definitely the best chinese kit by fair.

I still have not received my package, it was delivered to the wrong address.

Very happy with this kit. Easy to install. This is really powerful so I'd advise anybody with no prior ebike experience to be weary riding this. However, if you do buy this, you won't be disappointed with how much speed and power the kit produces.

Bike is good and reilable goes 43k battery doesn’t last long if u just want it going around with friends not peddling besides that everything fine I’ve just over 250km done on it and is good and reilable would recommend it

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

I like the uks6 lcd display it's the best looking model iv'e seen so far, !.

I am in love with this battery it’s very compact and beefy works like a dream in my daily ebike I use to commute to work

I HAVE NOT GOT IT FITTED YET AS IT WAS DELIVERED WITHOUT THE BATTERY,I WAS IN A RIGHT STATE,TILL I WAS INFORMED IT CAME FROM CHINA SEPERATELY.YOU PEOPLE SHOULD LET US KNOW WHEN WE ORDER STUFF THAT THE MAIN ITEM COMES LATER.I AM NOT HAPPY WITH THIS AT ALL.

Received..a bit of delivery delay.. haven't installed it yet..hope it's all good

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.

Delivery was super fast ordered on 2nd February, kit arrived on 10th and the battery on the 12th.

Excellent after service with Jason. Should be called J.Changebike..Time zones are different but you can get in touch with them early mornings,7am onwards. Email/whatsapp. The 60v kit is a excellent upgrade for off road use,the power from 2 -5 is more than enough for offroad fun whilst it also has a 250w mode for on road use which can be accessed through the plus button on The handle bar unit. Great kit

Fantastic service very helpful after would definatly order another kit. 10/10 service
