So I had just gotten off a trail near my house and while I was pedaling I heard a "pop" now every time I pedal with some force the bike vibrates. Any ideas guys? Thanks in advance.

Pop? Might be a spoke... vibrations can be caused by chainring wear and a new chain.
While chainwear can cause vibration, it wouldn't have a sudden onset. Look for something broken or moved, either a broken spoke, or possibly a broken rear axle that allows the rear wheel to move slightly and rub under high chain tension.
You might check the axle.wheel movement theory by standing on a pedal with the front brake locked and watching for deflections in the wheel.
