If you are one of those who think electric bikes are not good for exercise just because they have a motor, then you may be mistaken. It’s about how much exercise we are talking about.
As we all know, electric bicycles come with PAS (Pedal Assist System) which assists riders while they are pedalling, yes while they are pedaling. So, having a motor does not mean there is no effort at all.
Electric bikes gives you a luxury of choice, especially if you are a commuter. It’s totally up to you to decide either if you want to reach your destination sweaty and tired or let the motor do the lion's share of it.
Many ebikes have multiple Pedal Assist grades that offers you a choice from slight push to a high level battery assistant during the ride. So you can pedal with just a little effort while you are going to work and ride like a professional rider with a minimum battery assist on your way back home.
Also, having a battery assist while pedaling will help you to get more miles with the same or even less effort which means more exercise at the same time.
By the way, according to some researches commuters who switched to electric bikes showed significant improvements in their cardiovascular health and also improvements in their blood sugar.
So, yes, electric bikes are good for exercise even when Pedal Assist set to the highest level.
