Pedal brakes, also known as coaster brakes, are a simple and effective braking system found on many bikes, especially children's bikes and some older models. They work by engaging a mechanism within the rear hub when you pedal backward.
How Pedal Brakes Work:
- Pedal Backward: When you pedal backward, a lever inside the hub is activated.
- Brake Shoe Engagement: This lever pushes brake shoes against the inside of the wheel rim.
- Friction and Slowing: The friction between the brake shoes and the rim creates resistance, slowing the wheel down.
- Stopping Power: As you continue pedaling backward, the braking force increases, eventually bringing the bike to a stop.
Advantages of Pedal Brakes:
- Simplicity: They are relatively simple to operate and maintain.
- Accessibility: They are often found on entry-level bikes, making them accessible to beginners.
- No Handlebars: They allow riders to keep their hands on the handlebars, improving control and safety.
Disadvantages of Pedal Brakes:
- Limited Braking Power: They may not provide as much stopping power as hand brakes.
- Limited Control: They can be less precise in controlling speed compared to hand brakes.
- Not Suitable for All Bikes: They are not commonly found on high-performance bikes or bikes designed for aggressive riding.
Examples of Pedal Brakes:
- Children's Bikes: Pedal brakes are often the primary braking system on children's bikes due to their ease of use.
- Cruiser Bikes: Some cruiser bikes feature pedal brakes as a nostalgic or aesthetic element.
In summary, pedal brakes are a simple and effective braking system that works by engaging a mechanism within the rear hub when you pedal backward, creating friction and slowing the wheel down.
