• Drivetrain: The system of gears, chain, and pedals that transmit power from the rider to the wheels
• Brakes: The system responsible for slowing or stopping the bike

Common failure points

Some common failure points to watch out for include:

• Worn or damaged brake pads
• Loose or corroded bolts and screws
• Frayed or broken cables
• Cracked or damaged tires

Loosen the caliper bolts and adjust the calipers to the recommended distance from the rim.

Step 3: Tighten the Caliper Bolts

Tighten the caliper bolts in a star pattern to ensure even pressure.

Fixing a Flat Tire

Step 1: Remove the Wheel

Remove the wheel from the bike and deflate the tire completely.

Step 2: Inspect the Tire

Inspect the tire for punctures or damage. If you find a puncture, mark it with a piece of chalk.

Step 3: Remove the Tire

Use tire levers to remove the tire from the rim.

Step 4: Inspect the Tube

Inspect the tube for punctures or damage. If you find a puncture, patch or replace the tube.

Step 5: Reinstall the Tire

Reinstall the tire and inflate it to the recommended pressure.
