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%.
Overall well impressed.

It's my first time buying such a kit, I've done many research before choosing the one that could fit with my MTB full suspension and when I randomly met Kirby website I got shocked by the comments and mostly the prices, so I gave it a try. Best choice ever!

Also I'm really amazed by the fast delivery and response from the team that helped me track the other packages as it came separately. Thanks so much Kirbebike!

Highly recommend these kits, sure you can take a few hours (4 in my case) to get it done and i wont lie, there were lots of cuss words going on, but overall i'm so happy with the end result.
Its certainly given my bike a new lease of life and me a new love for biking. For my needs it works really well, also the price of the kit and battery were the cheapest i found.

Kit works fine. It took two days to install as it required new caliper spacers and 160mm wheels to fit on my 700c wheelbase bike. This was an extra cost I didn't expect. The motor performs well and is not too noisy. The display is good. Lights work well. Would buy again.

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.

Very impressed with the service and feedback from the guys here, I had lots of questions and after ordering they let me make some slight changes to the order due to my own mistakes. The kit is of great quality and not as hard to install as I thought it would be. Ive only ridden the bike maybe 4/5 times but the power is incredible. Excellent service and wouldn't hesitate to buy from these guys again !

Need to protect a second son! I love they are all keyed the same. Makes it easier!

I needed a low power front wheel kit to give me more range and a little extra pull on steep hills with my 250 watt mid drive motor. This 350watt kit delivers perfectly.

WARNING to Shimano owners: you need to buy the lower bracket tool to remove the original pedal bearings. I messed up and got all excited that i could get my motor installed the day of and then ran into this roadblock and had to wait a few extra days for the tool to arrive.

Parts arrived two weeks later, quality was good, especially wheels. Sensor installation was difficult, but video was helpful. Throttle had initial issues. Don't store the controller in warm weather. Bag for winter/summer recommended. Very valuable.
