When I tell people I have a bike with a box in the front - a bakfiets - they can never quite visualize it. This is an Amsterdam minivan. There is a little bench in the box with two seatbelts for your kids. Now I ride with the baby's carseat in front with a child's seat on the rack behind me for V. I have thighs of steel.
We had a graffiti artist make it a little more "us" with a skull and crossbones on the front, flames on the side, and Amsterdam's triple-x shield on the back.
I don't know what I'd do without my bakfiets. It has given me more mobility than a car would and it's free to park. People consider it sort of an Amsterdam yuppie status symbol (no wonder, considering how expensive they are), but it's really a necessity for me. They make much bigger ones with three wheels. It is a common sight here to see tiny Dutch women pushing around 3 or 4 kids in one of these rolling living rooms.
I have actually taken my cat to the vet on this bike with my son's feet on top of the carrier, while I was 7 months pregnant. My partner said if I'd have sent a photo of that to Immigration, they'd have granted me permanent Dutch citizenship.
If I ever find the bastard who stole my first bakfiets, there won't be enough of him left to bury. That's why the Dutch invented bike insurance. Cue Goldmember "Isn't dat vierd?"
