This kit has satisfied my needs. My needs included, traveling up 8km’s of steep hills at high speed, fighting through downtown Vancouver traffic, arriving at my destination not covered in sweat, and running errands. I do recommend this kit to anyone looking for a sweat free ride. It will get you to work quicker! I save around 15-25 minutes every day on my commute, this time savings can really add up! Installation Notes: The installation process for this kit can be tough. As a trained computer tech, and bike repair tech I found a few hurtles. For instance, the brake disk has a hard time fitting into my caliper, this is more the calipers fault then the kits…but the engine does push out the rotor a few millimeters. I now need to replace the caliper, since it can only be adjusted one way, or use thin brake pads. There are many minor things that can take you hours to fiddle through, which I don’t want to bore you with. Over all if you have the tools and the know-how, but do not have the time, I suggest getting a professional to put this kit in. If you are adventurous, technical, and don’t mind jimmying stuff into place, then install it yourself! Just make sure to take your time, go slow, and get it done right the first time.
