Pedals

Pedals thread into the crank arms. Worn bearings, bent axles or broken platforms are common reasons to replace them, and the job takes a few minutes once you know one key fact: the left pedal threads the opposite way.

What it's used for

Replace pedals that wobble, grind, are bent, or have lost their grip. Clicking or creaking while you pedal can also come from loose pedals, so check them as part of E-bike noises.

What to look for

• Left and right. Park Tool explains that the left pedal has a left-hand thread, loosening clockwise and tightening counterclockwise, while the right pedal uses a normal thread. Many pedals are stamped L or R (Park Tool pedal installation and removal).
• Thread size. Park Tool mentions both 9/16 inch and 1/2 inch pedal threads (Park Tool). Most adult bikes use 9/16 inch, but check your old pedals or your manual before buying.
• The right tool. Park Tool calls for a pedal wrench, or a hex key for pedals with a hex fitting on the back, and warns against using a cone wrench (Park Tool). See Hex keys.
• Grease. Park Tool says to grease both pedal threads well before fitting (Park Tool).
• A wide platform. Heavier e-bikes and riders often prefer a large, grippy platform pedal.
