Backpacks are great in many ways, not the least of which is that it comes with you when you get off the bike. A negative: in warmer weather, you can really sweat while wearing a pack.

Bikes are great for carrying stuff, even large, heavy loads. Here are some methods:

• simplest: backpack, small bag on the handlebars
• a rack on the back of the bike, with a milk crate (free) attached to it.
• Strap larger things directly to the rack. Make sure objects and bungees are tightly secured--the study of how to secure your load in this fashion is referred to as "bungee science*"
• baskets can be attached to the rear rack and to your handlebars. A heavy load on the handlebars makes steering difficult. DIY project: you can build yourself a customized basket bike by adding supporting tubes that rest on the bike frame, and attaching baskets directly to these tubes. Then you can carry more weight without affecting the steering.
• For more money, you can purchase panniers, bags made to be carried on a bike rack. Some bags are waterproof, and some convert to backpacks. See your local bike shop.
• for touring: a rack can be attached to the front of some bikes, to which you can attach smaller panniers. Many bike-tourists use a handlebar bag with a clear plastic top, through which to see your map.
• Xtracycle--a bike with an elongated back end. It has carrying capacity similar to a trailer but with no extra wheels. Check out www.xtracycle.com.
• Trailers are the best way to haul very large loads by bicycle.  Some trailers are smaller and more nimble, convenient if you frequently carry medium-sized loads or light, bulky objects. A common one is the B.O.B. yak model.
