Who rides to get around with their small children, and how do you carry them? Our son is nearly eleven months old, and I haven't yet found a good way to carry him around. I think I have a solution, but I haven't yet been able to afford to put it together.
I tried a Burley trailer and pretty much hated it. Silas tolerated it. I didn't like being so far away from him and placing him in a pod-like structure all alone. I didn't like attaching and detaching the trailer. I thought about having a dedicated child trailer bike, but I realized that once the trailer is on the bike things like parking the bike, getting on the commuter train, etc. are problematic.
The trailer doesn't work for me. We have all kinds of little errands to run in our neighborhood. Most of our destinations are within a ten or fifteen minute walk, and I'll usually choose to walk rather than hitch up the trailer.
My wife and I use various baby-wearing contraptions, and I've found that wrapping him on my back or putting him in a Mei-Tei works well for short trips. I pop a helmet on him and we're off. Since he's on my back and I'm leaning forward a little on the bike this is surprisingly comfortable for both of us. He can see over my shoulder and has a good time. I believe this method is not unusual in Amsterdam or Copenhagen, but here I'm afraid I'll get CPS called on me for endangering my child. I can handle CPS, but my wife has put the keibash on said arrangement, so it isn't an option.
I am going to get an Xtracycle soon and get the child seat they sell with it. I haven't tried this myself, but I've heard good reviews from people I trust. The seat they sell isn't made by them, it's just a nice rear child seat, but a little more sturdy than most (rated for up to 50 lbs.) On most bikes, these seats make the handling very dodgy, because the child's weight is over the rear wheel. But of course the Xtracycle moves the rear wheel back 15 inches, so child's weight is in the center of the wheelbase, making the handling much improved.
I am excited to try this out, and I've come up with a Frankenbike arrangement to make the bike work for both me and my wife (6' and 5'5") which involves two handlebars and a whole lotta ugly.
If you have children and you don't want to drive, there don't seem to be many good options. If anyone knows of anything out there that fits the bill, please post it in the comments section.
