I have installed and removed clipless pedals but not these-need to change from one bike to the next. How do I remove my ultra 6700 carbon SPD clipless pedals from my bicycle's crank arm

Go and buy a Pedal Wrench (at your Local Bike Shop, or online).
If you buy it from your LBS, then they'll happily demonstrate how to use it, otherwise do a search for Bike Wrench on You Tube.
Hope this helps.

How to get pedals off

the pedals are reverse threaded. So instead of "righty tighty" it's just the opposite.

I cant remove my bike pedals

Frozenbike pedals are not a problem if you follow a few simple steps. To begin with,the Right Pedal is standard, and the Left Pedal is Reverse Thread. If you areturning the wrong way, they will never come off. The trick is to use thecorrect wrench, skinny enough to slide in place without slop, and try toposition the wrench next to the Crank Arm in such a way that you can squeezethe Pedal Arm and Wrench together as if giving a very firm hand shake. Justsqueeze hard, and 90% of the time it will break free. If it doesn't, then sprayWD-40 or some other penetrating lubricant on both sides of the threads takingcare not to contaminate the grease inside the pedal bearings. You might have togive it a good soak, and bang the metal crank arm several times to make thelubricate work its way into the thread, sometimes leaving it for 24-hours canmake easy removal the next day. Remember, the Right Pedal is Right, and theLeft Pedal is Reverse, meaning, the Right Pedal tightens normally in theclockwise direction, and loosens in the counter-clockwise direction. The Rightpedal is from the Bike Riders perspective, when sitting on the bike, the Rightpedal is on the Right Side. An extension pipe can be slipped over the wrenchextending its length 2 or 3 feet, and will bust free just about anything frozentogether, however such a method risks damage, and you might end up needing toreplace the Crank Arm.

Change bike pedals

You need a 15mm wrench. Right pedal is threaded as normal. The left pedal is threaded backwards. (righty loocy lefty tighty.) there should be wrench flats where the pedals go into the crank arms. When istaling new pedals, put some white lithium grease on the threads. Be careful not to hit your knuckles on the ground when it comes undone.

Want to take the pedals off. did not get manual with this new bike. Does it take special tools to take off pedals?

No, it doesn't take any special tools. You just need to have the right sized wrench and something to hold the crank stationary but you can hold it stationary yourself if necessary.

How do you remove the pedals from the bike?

You should be able to use a box end wrench on the spindle.

This is a video link of a website I use and reference for all my bicycle maintenance.

How do you remove the pedals

You usually need a pedal wrench. They are thin and easily slid on the pedal nut. 17mm or 19mm typically, depending on bike/pedal size.

My left pedal is broken because it's really worn inside the pedal and I need to replace my pedals.

There are two thread sizes for pedals, make sure you get the right ones. Take the old one with you to the store.

You'll need a crank/pedal wrench to take the pedal off. The gap is too smal to get a normal size wrench in there, but you might get lucky.

Use some penetrating fluid on the thread and leave it overnight before you do it, as they are notorious for getting stuck on. Have a friend stand on the other pedal to keep it still, and undo it.

Tighten up the new one, remember the threads are backwards to normal tightening. Happy riding - vote for me please :)

Remove the pedals from a boys huffy bike

Bike pedals can be a little tricky, but most likely for that bike you will need a 9/16's wrench. There should be some flat surfaces inboard of the pedals between the crank arm (the long arm that you screw the pedals into). Now, here's the hard part - the R pedal is normally threaded, but the L pedal is reversed. The easiest way to remember which way to turn the wrench is to stand behind the rear wheel and you will always pull the wrench towards you to loosen. Depending on how long the pedals have been on, they might be pretty tough to get off. You could use some penetrating spray (like Liquid Wrench) and let that sit for awhile. Also, once you get the pedals off, remember to put a little grease on the threads so that next time they won't be so tough!.

Pd -m424 cant get pedals off bike? do i need to use allen key as well as spanner

No, you do not need to use both. In fact, you should never use a spanner wrench to remove your pedals or anything requiring large amounts of torque. For removing your pedals you should be using an pedal wrench or if the pedals are not very tight the allen wrench. A basic pedal wrench like the Park PW-5 is inexpensive and does a great job. Also remember that the non-drive side(left) is reverse threads, meaning both sides come off by unthreading to the rear of the bike.

Hope this helps. Thank you
