Mongoose Ledge 2.1 pedal thread size

I want to replace the pedals on a Mongoose Ledge 2.1 26" MTN bike. Its a relatively cheap bike so I don't want anything too expensive and I am unsure of the pedal thread size. I know 9/16" is standard, I also know some cheaper bikes use 1/2" and since it is hard to get an exact measurement from the thread itself I need an answer. Between the pedal thread and the crank hole it could measure either way. Anyone know for sure, I want to buy the right size the first time. THANKS!!

    I would have to buy either a caliper set or a micrometer to do it. Its too colse to call with a tape measure or ruler. Thanks though, if i had the tools avalible it would be done.

Measure the threads on the crank. Use or borow a pair of calipers. Measure with two threads as the outside edges to get proper diameter.

    I will answer my own question here, 9/16" is the thread size. The obvious part i missed was my bike has a 3 piece crank. While not always the case a 3 piece crank usually uses 9/16" pedals, while a 1 piece crank usually will use 1/2" pedals. I did say usually because there are exceptions, but in this case it holds true. Thanks!

What is a decent replacement rear derailleur for a Mongoose 26" Ledge 2.1 Mountain Bike?

Get the kind that has a lever shift instead of the grip shifter. The plastic part that holds the spring breaks easily. The lever shifter has been going strong on my bike for 6 years without a problem

There are no threads on the crank arm to screw a pedal on. What do you do now?

1. replace the crank.
2. Purchase a Heli-Coil or other brand at an auto store. It looks like a tube with threads on both sides that will screw in to the stripped hole and there by install new threads. Bring the pedal to the auto store to make sure it will thread in to the "female" threads on the Heli-coil.

The problem is the pedal is steel and the crank arm is soft aluminum. Also, people damage them because one pedal is normal thread and the other is reverse thread meaning you turn clockwise to loosen.

Stripped bicycle pedal

Better replace the pedal and most probably the crank arm as well. Sometimes a new pedal can cut the threads true again on the crank arm but the crank arm may need replacement too, depending on the damage. Remember to fit the correct side pedal. The pedal threads differ between left and right and pedals are usually marked "L" or "R".

They stole my bikes pedals and I want to know what size they are to buy them?

Being a mtn bike it probably had flat pedals or lock-in SPD. Either way, pedals dont come in sizes, the shoes do. A pair of pedals will fit ANY bike, just select the type you want. Just be careful when screwing on, there is a LEFT PEDAL and a RIGHT PEDAL. They screw on in oppposite directions.!

I need to know what kind of crankshaft does a mongoose men's melee have?

Ya mean BOTTOM BRACKET? Probably something at the low end of Shimano. They don't publish the minutae for their department store bikes.

You could ask Mongoose directly or take it your Local Bike Shop and have them determine the answer (which is recommended in Mongoose's manual if you want service on a 3-piece crankset anyway).

Determining pedal size for 26 inch schwinn mirada bicycle and compatable upgrade pedals

This write-up explains it in detail.

Search the page for "Thread sizes".

As far as upgrade pedals go, that would depend on the rider's preferences (toe straps, clipless) and comfort level with them. A Bike Shop will probably stock and install anything you could want.

Keep in mind that the left side is left threaded.
