E-bikes can be expensive, as you've already seen if you've searched online, especially when you're staring at a perfect manual bike. An EBike conversion kit is more appropriate, depending on your situation. They offer several advantages that may offset the price of an EBike. The clue is in the title. Ebike conversion kits are required if you want to turn your existing pushbike into an eBike. It is not uncommon for hub motors to be geared to a specific wheel size to meet local speed regulations for electric bikes. For example, at low speeds, a hub geared for a large wheel can be inserted into a smaller one, resulting in tremendous pulling power. It's as simple as that! There are several different eBike conversion kits on the market, each with its own set of advantages and disadvantages.
