Can you coast with a coaster brake?

With a coaster brake, the rider can decide to stop pedaling forward and simply “coast” or pedal backward to brake if needed. Because the coaster brake is housed inside the rear hub, it’s unlikely to squeak or require cleaning and works just as effectively in rainy conditions.

Are coaster brakes safe?

Coaster brakes are great as a fail-safe fall-back: They pretty much only fail if the chain falls off. So, as long as you can ride your bike forward, you are also able to stop it with the coaster brake. Thus, a good front brake for normal breaking plus a coaster brake to save you when your cable breaks is a great combo.
