I love to cycle and live at the top of a large hill. Unfortunately I have severe arthritis and need to bilateral knee replacements. My electric bike let's me make it home without straining my knees.

We have been using the conversion kits on two of our bikes for the past 5 years to get us up the hilly parts of our long commute across San Francisco with our growing son as a passenger. The additional power has enabled us to continue to get exercise. We have now bought another 350w kit for our Tandem bike to take over as our SUV for commuting to school. I wish the cabling were more easily customizable so that I did not have extra coaxial cable looped and bunched near my seat stem.

After using this electric bike kit for a few weeks, I am very pleased with the performance of the product. I certainly would recommend this product to anyone. I am about to go through an entire WI winter with it. Im curious to find out how it holds up to very cold temperatures and snow. I ride everyday in all types of weather, so it's very important that the this product does not fail me when faced with many different weather elements. So far, in the month of October here in WI, its been wonderful!

My wheel is fairly new, but I have used it several times. My bike use is primarily for running around town for errands and the like. I live in a very hilly town near mountains. I have found as I am growing older that I was resisting using my bike on account of the hills. My wheel has had the effect of "flattening" out my routes so they feel more like a town on the flats rather than hanging on the hills. I had no trouble installing it. I did replace the tire and tube with the one on my other wheel - easy stuff. I am very happy with this product.

I love it. It makes riding my bike fun now so I actually do it. I live in a very windy area and I am a large person so it was always very hard to go against the wind. Not now.

Your kit has changed my life! I ride everywhere in Tampa, FL because the kit has freed me from the fear of over-doing it. I'll be 71 in July and I am like a 10-yr-old with a new bike at Christmas. Since I installed the conversion kit, I have put over 800 miles on my bike and now my wife also rides with me. And we get more exercise now with our bikes than before.

I have used the Lvbu conversion kits for more than 3 years and even with the oldest one I bought all the way back in 2021, it still functions very well and achieves very good range for both short distances and long distances.
