Repairing a Flat Tire
To repair a flat tire on a bicycle, start by removing the wheel from the bike. Use tire levers to carefully remove the tire from the rim, then inspect the inner tube for punctures or damage. Patch or replace the inner tube as needed, and then reassemble the tire and wheel. Inflate the tire to the recommended pressure and reattach it to the bike.
Adjusting Gears
To adjust the gears on a bicycle, start by shifting the chain to the smallest front and rear gears. Use the barrel adjuster on the derailleur to fine-tune the shifting, ensuring the chain moves smoothly between gears. If the gears are still not shifting properly, check for cable tension and make adjustments as needed. Test the gears by riding the bike and make further adjustments if necessary.
