The kit is from http://www.ebikekit.com/
It's fairly quiet, but about the same as my other hub motor bikes.
We are very lucky here in the Chicago area when it comes to bike trails. There are hundreds of miles of trails just like this all over Chicago and vicinity.
This is the one i love the most of all the ones i have built so far.
A ride through the park on the bike, GoPro style.
An expensive kit, but overall, i love it. You can see some of the others i have built if you look around on my youtube page.
