Wow, this kit has everything you need to convert a regular pedal bike, in my case a 26" wheel mountain bike, into smooth, powerful workout/commuting machine! It's very well thought out and was very easy to assemble, assuming you have experience taking wheels off, adjusting brakes, etc. What I really appreciate is I can remove the battery and swap the front wheel out in less than 5 mins and have my lightweight mountain bike back whenever I chose to. The workout potential of this bike is huge, with my kit installed I can power this bike on road at speeds of 25 mph and cover vast distances simultaneously, it's very inspiring. I can't wait to try out the new lighter battery, the original one is a little heavy, but still a great performer. -thanks, SwytchBike, Mark Gilbert, FL, USA.
