Voodoo Bokor knocking sound from the pedal

Hi.

I bought a Voodoo Bokor off ebay a few months ago. The bike was stock and didn't come with any manuals.

It developed a knocking sound on the left pedal recently. It's happening only if I pedal down hard, and when the pedal is slightly after the top position. Otherwise it's pretty much silent.

I've taken a sound recording of it inside a parking garage. I was using the brakes and pedalling hard.

I'm wondering what might be wrong with it?

Unfortunately, I don't have any tools apart from a Leatherman and a multi tool allen wrench, which I know is silly for someone who owns a mountain bike. I haven't had the bike for long and didn't need tools before. I'm thinking of buying one of those 50 or 100 piece tool sets from Halfords or somewhere similar. What are your thoughts on that?

    Sounds like the crank is loose, not sure what is fitted to the Bokor but look for the manuals on the relavant website and fix it!

    I've had a chance to spend a bit of time on it yesterday. I always suspected the pedal itself to be the culprit and it seems that it is.

    I've removed the left pedal from the crank and attached one from another bike and the noise disappeared completely.

    I took the pedal apart, just to see its construction, put it back together, and then thought, what the hell, I'll give it try, and it worked! It's all quiet now.
