- If you already have ridden a lot, skip this guide and get what you know you want/need. If not, proceed to point 2.
- Think about where you'd like to ride. On the roads? Get a road bike. Trails and other offroad stuff? Get a MTB. On the roads, but in crappy conditions? Maybe a cyclocross. Don't get too hung up on this phase, though. Any bike is nice to ride, and most are a lot more versatile than most people think. Proceed to point 3.
- Find one that fits. This is where your bike-buying can really eat dirt. You need to find a good bike shop with staff that know their business. Proceed to point 4.
- Can you afford it? If not, find a cheaper one (and make sure that it fits). If yes, proceed to point 5.
- Do you like what it looks like? If not, find another one. Can't be riding ugly bikes. If yes, buy it.
- Ride a lot.
- When buying the next bike, you know better (see point 1) and can make a more accurate decision. And maybe still keep the first one.
