I decided to purchase a kit for my Bianchi road bike. Although it isn’t intended for this type of bike, a few minor modifications & it was good to go. Since I only wanted light assistance so that I can still get a good workout, the range of the battery is fine. Also the kit is very light so I can still viably ride even if I do run out of battery power. Love it.

This ebike conversion system is so easy to install, and the performance is so excellent. when you compare the cost of an E bike in the market to what the ebike system cost you, this system would be the obvious choice. Since I installed the motor on my bike, I love biking even more.

I've had this kit for just under a year and so far my experience with them has been great. It does take what feels like forever to get the kit but once you do it was easy to install, great customer experience and the motor gives me just enough of a boost to make riding my bike that much more enjoyable. I'd definitely recommend it to someone who has an acoustic bike they love and wish they could go electric without having to give it up!

The kit is exactly what I needed for my Specialized CrossTrail. The instructions for installing were very clear and installation took me about 3 hours but I took a lot of time to ensure I was getting it right. I had to contact them regarding the pedal sensor and they replied quickly with the right information, and after a few discussions and photos, it came out great! The system works very smoothly and helps me when I want it to and I can shut it off when I don’t want it- I still feel like a purist and not a scooter driver!

I have two conversion kits from LVBU: one BX30D I bought in 2019, and the second, a KF30S purchased in 2022. I am expecting the third one, a 500W version. I have run hundreds of kilometres with my bike and my daughter. We both love it. I had three e-bikes before lvbu, and I still prefer my upgraded bike to the ones I had before. Easy to install, no maintenance.

I love it. So easy to fit and awesome to use. I was nicely surprised on how speedy it is on 99%. But I normally use around 50% for distance as I use on an adult trike. I recently cycled from Hull to Paull. I highly recommend the lvbu ebike kits for any cyclists.

I really liked how easy the installation process was. Buying process was fairly simple., you just need to validate some measurement on yourbicycle. I would like to see shipping delays improved. There seems to be no web store available for us in Canada to buy more accessories (e.g. a second charger set or additional battery pack). Overall, I'm very happy with the kit.
