The speed of a traditional bicycle depends entirely on the rider's pedaling. If you paddle fast, you will be able to run much faster. On the other hand, if you want, you can run very slow. 

However, when it comes to electric City bikes, their main power source comes from their batteries, motors, and throttles, yet you have to do most of the work. These bikes are fun to ride, fast, and environmentally friendly. With the ability to cover long distances in a short time, they can be a great way to get around the city and explore new places. 

But, how fast do electric City bikes go? Well, With speeds of up to 15.5 Mph or 25 km/h, these custom pedal-assisted bikes can give you the most comfortable riding experience, powerful performance, the ability to cut down on your travel time, and experience more surroundings in less time.
