I’m thinking of buying a bicycle. What factors should I consider?

If you’re in the market for a new bike, you may want to think first about where you intend to bike — on trails or on roads — before buying one. If you intend to ride on roads, you will want either a road bike with fairly thin tires and a lightweight frame or a somewhat heavier “city bike.” If you prefer biking on trails, you’ll probably need a mountain bike. If you think you may be riding on both roads and fairly flat trails, a hybrid bicycle might be right for you.
