clicking sound while pedaling

Hi everyone, I would greatly appreciate it if someone could help me diagnose some sounds my bike is making:

I get fairly loud clicking noises when I pedal. It's hard to tell what kind of pedaling causes it. But sometimes there's even a few in rapid succession (often when going over a bump) and then it's almost a ratcheting sound. It's not just a matter of a certain pressure on the pedal, but it's more likely if there's more pressure it seems.

It's almost like the chain slips a little; I feel it, not just hear it.

here are a couple videos of the clicking in action:

Let me know what you think, or if you want any other info. thanks

(I've searched for a while - the BB seems to be blamed in other threads, but I don't see why it would kind of snap like that or do the rapid clicking sometimes)

I looked at the first video, but it didn't tell me much.

First things I would try:
1. Remove the pedals from the cranks and replace with another set.
2. Take the chain off the crank and spin the crank.

If neither of these isolated the problem, I would begin to suspect chain rings or chain ring bolts.

It looks like it has a kickstand though your camera is only showing the right hand side of the cycle.
Anyway, if it does have a kickstand, your left pedal is hitting it.
Just move it in and tighten it up.

If you have the tools to do it (or you can get the tools to do it pretty cheap). I just had what looks to be the same issue. I just removed my cranks and cartridge bottom bracket, and greased all the threads and put it back together. I no longer have this clicking. Im not sure if I just got lucky, or if this is a common thing to happen. So for ~$20 in tools, I got it fixed for less than the LBS would charge for a new BB if thats what they would have changed.

Also, if you do decide to get the tools, pay the extra $2 for the Park crank puller, dont get the Nashbar one and have it brake on you like I did... I didnt notice the prices were so similar, or I would have gotten the park the first time!

Could be what I had, where the previous owner overtightened the crank arm to the square taper spindle creating a bigger crank hole. For me the looseness between the two metal joints under stress, is what was causing the clicking. I replaced the faulty part with a Shimano Sora crank and I dont have that clicking anymore.

yeah, the kickstand is loose and that's what i thought at first, but it's definitely not the kickstand.

did you ever have multiple clicks in rapid succession where it sounds like someone ratcheting something?

I had a similar thing going on with my Trex 7.3FX for me it was just a matter of tightening things back up as they had came loose after about 500 miles of riding. I did take it to the LBS to have them deal with it because the bike was only 3 months old essentially.

I've got a click in my left pedal when the left pedal gets to the bottom only when riding. If I turn the pedals by hand with the bike upside down there is no click.

Any suggestions?

Time to replace the pedals, or rebuild them.

Nope, the only time I heard the clicking was when I was quickly accelerating, or climbing a hill or and other reason to be applying a harder force than just a normal cruising. (Can you tell I am in the middle of physics/dynamics homework, lol?).

I always had the click in the exact same 1/8th of a turn from my non-drive crank being straight up.

I had this issue with a new crank and new pedals. Thought it was the bearings. But, it turned out to be caused by pedal threads in crank arm, because when I switched pedals and then switched back to teh originals teh sound dissappeared. I relubed the threads so it was either that or the other pedal modified the threads in the crank slightly.
