This was a great way to convert your bike to an e-bike. When the order arrived it was very simple to install on my existing bike and was using it very quickly. It's fun to ride and the product delvers in almost every way. There are only a few things I can point out that would make this a better product and the first one is battery capacity. I ordered the largest battery and it doesn't last as long as it was advertised. On a full charge I can probably get 10 miles at the very most and I wish that it would allow for more. That brings me to the only other thing I would like to see improved and that is the ability to order replacement parts or even extra batteries after purchasing the kit. I broke the speedometer while upgrading some of the parts on the bike and in order to get a replacement for this I had to email customer service and ask them to order it for me and because of miscommunication the part they sent me was the standard speedometer and not the OLED that I wanted so it would be much easier if there was a store you could visit and pick the part you want. I would also love to get an extra battery but don't really want to go through emailing customer service and maybe getting the wrong part. Those are two small things that kept me from giving it 5 stars but if you are looking for an ebike this wont let you down.
