im looking to buy my first bike and the thing is, i don't have any mates who ride. so i can't take anyone along with me when checking out used bikes. i've read the forums and there's some great advice here on what i should look out for. ... but im still curious - do i need to get a bike mechanic to inspect a bike or will me running through the checklist be enough? what would/did you do with no-one to help you on buying your first bike?
