If you've never done it, bicycle riding in a major city is definitely an experience. Pedal bicycles, in particular, are interesting because you're the motor, but you have to also find a way to function with cars, trucks, motorbikes, and everything else that makes up a city's regular traffic.
You're also able to move more quickly than you would be walking, and at the same time, you're out on the street with other vehicular traffic that may or may not be paying attention to you. Sometimes there are dedicated bike lanes, and sometimes there aren't. And sometimes, drivers and other road users honor those bicycle lanes, and sometimes they don't. There are a ton of variables to consider, all of which will affect the experience you have while riding your chosen bicycle to your destination.
E-bikes add yet another variable to the equation. Striking a balance somewhere between a pedal bicycle and a much faster motorbike, they give a little extra boost to your bicycle experience through their addition of batteries and a motor. Pedal-assist e-bikes make it easier and more pleasant if you want to arrive at your destination without being all sweaty, and can also be particularly helpful if you're disabled or recovering from an injury.
