No market for them, eh? I must have seen half a dozen over the past week alone. And since local shops won't sell them, the cargo-bike-starved population of Boston is forced to travel to Portland ME or NYC to shop for them, or else order online, or else attempt to get them direct from the distributor with lots of behind the scenes begging. Odd really.
I think cargo bikes are important in that they indicate how far a city has come in embracing and normalising transportational cycling. They equate cycling with safety and comfort, as opposed to danger and athletic skill. The mere sight of cargo bikes suggests:
"Look, people here must feel comfortable carting around their children by bike!"
"Look, there are people here who even replace their trucks with bikes!"
"Look, it must be okay here for bicycles to take up lots of room on the road!"
And of course when people see signs that something is okay to do because it looks like others do it, they are more likely to consider doing it themselves. So even if they do not need or want a cargo bike per se, they may be more likely to look into cycling with their children, cycling with baggage, cycling on the road, and other aspects of transportational cycling because these ideas are suggested by the mere existence of cargo bikes.
I suppose a simpler way of saying what I am trying to say might be that cargo bikes are symbolic of a strong, healthy "bike culture." Going with this premise, I am pleased that more of them are popping up in Boston and wish the industry would take note. What about your city?
