Kit arrived quickly and well packaged from Kirbebike.
Straight forward installation onto a Claud Butler Hybrid. Weight of bike is now 15.7Kg, which is a lot lighter than most E Bikes.
Have tested on a 17 mile bike ride with numerous hills / muddy farm tracks and the performance was good. After the ride the battery level is 34.6v with battery display showing around 30%.
Only issue is with display "fogging" up, which has been reported by other users.
Overall well impressed.

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.

I love this kit, the power is insane for an ebike kit, very good battery size for 60v20ah and great quality battery cells, reliable fast kit, love it!Very good battery size for 60v20ah and great quality battery cells.

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.

Overall kit seems really good, took a little adjustment on the settings to get the bike running sweetly.
Make sure you look at the freehub/freewheel differences when purchasing so you have the correct parts to fit the wheel kit.
Jason has been pretty quick on replies and very helpful.

I have had this motor installed for about 1 month and have had no issues. Easy install. Package came within the time stated. I did get the brake handles sent separately but I didn't need them right away. Motor and battery work great so far after almost 200 miles. Have fun it's way better than buying an ebike with less power. Just make sure your bike is ready and can handle the power. I had to tweak a few things to adjust.

Bought the 48v 1000w kit for my Carrera mountain bike. Don't have much bad to say - it's a good conversion kit which works well, although I've only used it for a week. The speed is good for what I need, it can climb hills, and it's a simple piece of kit to build if you know you're way around a bike. Controller can get a little hot, but I think that might be normal. Overall, I'd recommend it.

The level of care and attention I received truly made a difference. Not only did they have my best interests in mind, but they also made the entire experience enjoyable. I highly recommend KirbEbike to anyone seeking quality products and exceptional customer service. I’ll definitely be sharing their services with my family and friends.

It blows away any factory-built 250-watt kit I have ever tried while keeping a low profile of being the same size as a 250-watt still! The kit was straight forward enough to install, it's very comprehensive with an included toolkit
& brake sensors for both hydraulic & cable systems, most kits
do not include hydraulic sensors you have to buy them separately usually, you also get pedal assist sensors for Shimano square tapered bottom brackets & older design cranks so it covers all the bases. The 48v 20ah battery has very good range, I got 60 miles on my first charge with 1 red light so 25% charge still.

1. Amazing Power – This mid-drive motor tackles big hills with ease. The hub drive bike we rented on a vacation recently struggled on similar hills.
2. Shifting gears – She seldom shifts gears and typically stays in the same gear and power setting for the entire ride, but we found that shifting gears with the hub motor needs to be a planned event (only shift gears under light peddle pressure) Conversely, shifting gears on the hub drive (even under load) was seamless since it operates separately from the gears

I am well impressed with the quality look and feel to the battery as i have used other packs before from other brands and this pack is by far the better, well worth the money.

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 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.

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

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!!

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.

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.

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

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

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!!

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

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

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.

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