My bicycle feels harder to pedal What are possible causes and fixes

If your bicycle suddenly feels harder to pedal, there could be several reasons behind it. Here are the most common causes:

Underinflated tires: Insufficient air pressure in your tires increases rolling resistance, making it more difficult to pedal. Check your tire pressure using a gauge and inflate them to the recommended PSI.
Dirty drivetrain: A build-up of dirt and grime on your chain, cassette, and gears can increase friction, making pedaling harder. Clean and lubricate your drivetrain regularly.
Loose or worn bearings: Worn or misaligned bearings in your wheels, bottom bracket, or headset can cause drag and increase pedaling resistance. Check for any play or grinding noises and have them serviced by a mechanic if necessary.
Brakes rubbing: Misaligned or contaminated brake pads can rub against the rim, creating resistance. Adjust your brakes or clean the pads to eliminate friction.
Overloading the bike: Carrying heavy loads or riding with additional gear can add extra weight, making it harder to pedal. Distribute your weight evenly or reduce the load if possible.

Can a bent wheel make it harder to pedal? Yes, a bent wheel can cause drag and increased resistance.
How often should I clean my bicycle drivetrain? Every 100-150 miles or more often in wet or dirty conditions.
What is the best way to lubricate my bicycle chain? Use a dedicated bicycle chain lubricant and apply it sparingly to the inside of the chain links.
Can I fix loose bearings myself? Yes, but it requires some experience and specialized tools. If you're unsure, consult a mechanic.
What causes brake pads to contaminate? Dirt, debris, and oil can adhere to brake pads and reduce their effectiveness.
