Whats the best convertible bike trailer/stroller on the market?
Im a year-round bike commuter and errand runner (this summer I made a tank of gas last four months). However, the arrival of my son has altered my lifestyle. How old does he have to be before he can ride in a trailer? And which trailer do you recommend? I'd like it to convert to a stroller relatively easily. Also, wed like a double in case we are lucky enough to adopt a second child. Either that or just to accommodate enough groceries. Karin Mountain View, California
