>>1678688>>should I use a helmet?If it's not a law, no.
If it is, not if the cops don't care
If it is and the cops care, not if the bike paths give you an escape route
If it is and the cops could run you down easily, then I guess.
>>maintenance and prevention on the goLube chain when it starts squeaking, make sure you know how to install inner tubes properly, learn to adjust brakes+gears when they need it, don't run over glass and shit if you can avoid it, probably carry spare tube(s)+tire levers+co2 pump if you're going far enough that it'd be a nightmare to walk home.
Oh, and keep in mind that your tires will be a shitload narrower so stuff like big cracks or seams in the pavement are actually a huge fucking threat now. Seriously.
>>how to not get run overThrow your dignity out the window and dress in neon yellow. Wherever you ride assert your right to be there and don't try to crowd yourself close to the curb or something, but otoh defer to cars in all circumstances and get out of their way whenever you can.
>>what should I look for in a roadbike?Or can I continue using a mountain bike?Depends on your budget. A carbon fork is nice.
