>>1661177I fucking hate it when people say 'trails' because that can mean fucking anything. It can mean a nice paved trail or it can mean a gnarly freeride downhill trail with 30 foot hucks.
If you are only going to be riding on roads and paved and/or gravel trails, you can either get a hybrid (check
topnigger.ueuo.com for info on hybrids) which will cost around 500-800 dollars for a decent entry-level bike, or a used 1970s-1990s road bike which will cost anywhere from 100-500 dollars on craigslist or your country's equivilent, but if buying used, you'll most likely have to replace tires, tubes, brake pads, and chain, and potentially also some other components, so if you don't know what you're doing and need to rely on a shop, expect to put 100-200 dollars into a used bike unless you know what to look for and inspect it before buying to make sure all is in good shape. (old rubber is hard, brittle, and bad so tires/tubes/brake pads need to be replaced if they're old even if hardly used)
If by "trails" you mean mellow off-road mountain bike trails/singletrack, you can either go with a hybrid (which won't be great on mountain bike trails, but can do alright on really mellow mountain bike trails), or a used 1980s or 1990s rigid (non-suspension) mountain bike (same price and criteria as a used road bike).
If you mean technical intense mountain bike trails... you're not really getting anything at your price range, but your best bet would be an old used mountain bike.
