E-bikes are becoming increasingly popular amongst cyclists. Why? The best electric bikes increase the distances possible with commuter bikes and replace a car for running errands around town. It doesn't stop there. There are now electric bike options for every type of rider, regardless of whether you're a mountain biker or just a casual road bike enthusiast.

Of course, e-bikes aren't cheap and is an e-bike worth it?

Enter the e-bike conversion kit.

Put simply, e-bike conversion kits add the electric boost to an 'analogue' bike without the price tag of a full e-bike.  

You'll need to consider a few factors before buying an e-bike conversion kit. Obviously, the kit will need to fit the dimensions of your forks, width of the rear says and wheel sizes and the type of breaks you have. You’ll also want to consider where the motor will be located. Front hub motors are typically the easiest to fit, while mid-drive motors require more effort.  Other considerations include the type of battery and the wattage rating - 36 or 48 volt battery is standard, with wattage usually running from 300 to 600 watts.

But fear's far more simple than it sounds.

We'll guide you through the benefits an e-bike conversion kit has to offer and—crucially—how to perform an e-bike conversion. For a walk-through on how to do it, you can check out the video above or read on for a step-by-step guide.
