Lots of people are embracing the convenience, accessibility and environmental benefits of e-bikes. Cities, such as Denver, are offering rebates to encourage people to buy them. But, buying a brand-new e-bike isn’t the only option. With a conversion kit and a little DIY magic, you can turn your existing peddler into a motorized workhorse.

On the other hand, a kit allows you to add e-components to your favorite bike, which already fits you well and which you are already used to.”

An e-bike is a bicycle with an electric motor powered by a rechargeable battery. E-bikes usually include a control panel with a display mounted to the handlebars to show your speed, remaining battery power, and some other useful parameters.
