Having a bike that has a motor on it can provide quite a bit of value for different types of riders. Some people are going to really appreciate the ability to get to different places very quickly, while others are just going to be very happy about the fact that they do not have to put as much effort into tough riding situations. After all, there is nothing like having to struggle up a steep hill when the legs are already burning.

Whatever the reasoning might be, electric bike conversion kits are really starting to take off. It seems like fat bike riders particularly are finding just how beneficial they are, and prices are affordable enough that people are taking the plunge.

With more options out there than ever before, what are the best conversion kits to pick from? These five are just a step above the rest, especially when considering different price points.
