> Or is he in the window where he can't cycle far enough by himself, but too heavy to be safely steered on a cargo bike? My wife cycled me around in her cargo bike, and a couple of other adults (not at the same time). I'm not a light chap, fairly sure I'd outweigh both your kids together. Steering on those things is pretty good, they're not light in and of themselves. edit: we actually cycled both our kids to school in the cargo bike when they were 8 and 5. I'd forgotten, it was a few years ago.
