What kind of bike could I buy for around $500-700 that's fast and can ride on gravel/bumps? I'd mainly be riding on it the dike near my place which is rocky. Any tips?
Start by looking at an entry level hardtail mountain bike, or a used quality one. Also, look at gravel races, but realize that's out of your budget.

With that budget definitely go used. I'd say a decent mountainbike with at least deore/xt components should work nicely. If there's a lot of rocks I'd recommend a suspension fork and nice big tubeless tires.

A cyclo cross bike sounds like a good choice if you aren't riding gnarly trails and you want to go fast
