Our ebike kits fit 99% of bikes. Our kits have been shipped and installed on bicycles all over the world.

There are very few types of bikes that do not meet the size requirements, so be sure to measure the space at the point of the dropouts between the forks if you are concerned. To ensure proper fitting, do two things: 1) Check your wheel size listed on the tire to make sure it is either 16″, 20″, 24″, 26″, 27.5″, 700c, or 29er & 2) Measure your forks as they will need to be between 3.8 – 4.05 inches or around 99mm between the front forks. This is the point where the wheel axles connect to the bike. Please review the image below to ensure correct sizing prior to purchase.

    I have never seen instructions as bad as this. Whoever did this does not even understand what the word “video” means. In this website, video only shows a couple of pictures and instructions. That is not video. If video is not available, at least there are enough pictures for illustration purpose. There has to be a lot more pictures. The picture that shows the front drop spacing is one of the good one. However, even that is missing information as how wide the drop slot has to be. Well, let’s just say that I already lost about 5hrs installing this. And I just finally got the rear carrier attached. I think I made a big mistake buying this.
