"Superba" (which will look nothing like the Roadster rack above), so racks have been on my mind lately. I've been checking out the racks on practically every bike I see, and also paying attention to how I typically use mine.
Although on occasion I will carry a substantial amount of weight on the rear rack of my bike, more often than not all I carry is a single pannier or bag. Sometimes there are groceries and packages involved, and even those often fit into a single large pannier. Once in a while, I will strap an item or two to the top of the rack, but it is not an everyday occurrence. When I look around at other cyclists, at least in the Boston area, I see mostly the same: One or two panniers attached to the side of the rack, or a bag strapped to the top. If I see more than that being transported (on a regular bike, not an Extracycle or a "utility bike"), it's an anomaly.
What about you? Be honest - how much do you really carry on your bicycle's rear rack on a typical day, assuming that it is a standard city bike?
Looking at other cyclists in the Boston area, I've also noticed a gender difference in how much stuff cyclists carry - with women typically having fewer things strapped to the rear rack than men. But there could be many factors accounting for this, and I am not sure how typical this trend is overall.
Having discovered how to embed these polls and surveys, I admit it's fun to set them up and then look at all the results - but hopefully also useful. I will soon be receiving a sample of the "Superba" rack prototype, and from there it should be just a matter of time until we're done. These racks will fit a standard 700C wheel bike, and regardless of whether you are interested in a "Superba" bicycle, the racks may be available for sale on their own. They won't be sold by me, but I will keep you posted - and your input will certainly be valuable.
