So basically, i want to get a bike, i used to have one a while ago when i was in school but unfortunately my parents threw it out. ( i know, what the eff )
I have pretty much 0 idea on what to get, im looking for something that i can take on the roads, i can use for downhill and also mountain biking, basically an all-rounder if such a thing even exists.
Im looking to spend a few hundred dollars at the start until i get more used to the scene then ill look to spend a bit more. Please help.
Depending on the type of roads/ground your cycling on I would look for a cyclocross, these can be used on the road and pretty tough terrain as long as your not hitting routes that require suspension.
With your budget though you might want to think about saving or going for a cycle to work scheme/Finance if they do that where you live.
What you're posting above would suggest you want to start with a hardtail MTB. I'd look on eBay for a second hand Specialized Hardrock with disc brakes. See how you get on with that and then upgrade accordingly.
