First let's think why this occured. I believe this is what would happen if one used the left pedal for the right crank and the right pedal for the left crank arm. You see the pedals are made so they screw in with the same rotation as the pedal spins (on forward motion of course). So as you press the pedal the pedal, even if not screwed in correctly, it ...

Lets say you wish to replace a crank similar to yours and you cannot find the exact same crank as the one you have. BIG PICTURE: Unless you can find the exact same crank as yours, you'll need to purchase both a crank and matching bottom bracket. A guide for choosing a crank is listed below Measure the length of the Bottom Bracket shell. If it is 68mm or ...

There's plenty of options with that in mind, especially if you're open to used. If you want the same gearing, I'd suggest making sure the bolt circle diameter is the same. It should be 110cm. If ...

Pedals falling off is at best inconvenient, at worst can lead to crash and serious injury. Easiest option is to replace the cranks. Its not a big job but parts cost might mean a repair is a better option for you. The bottom bracket will ...

The only thing you can do that is safe and reliable and sane is to get a new crankset. You'd need a helicoil or something similar to do the repair reliably and this would be less strong than a new crankset and cost more than the new crankset + installation. Next time, make sure everything is greased and tightened properly.
