E-bikes are expensive, so that's their downside. Some cost nearly twice as much as a standard cargo bike, ranging from $2,000 to $5,000. Furthermore, they are heavier, so carrying them up a flight of stairs, fitting them on buses, or transporting them in a vehicle is hard.
E-bikes may require a license depending on where you live, and the class you choose will determine where you can ride. In the U.S., most e-bikes are categorized into three categories based on their top assisted speed and whether they have a throttle. People for Bikes, an advocacy group for cycling, keeps a state-by-state guide to e-bike regulations. Learn more about e-bikes in Intro to Electric Bikes.
