I rode in one one day: the most unconfortable mean of transportation I've ever been on! Literally, no suspension whatever!
How is it possible to treat children like that???
Well, I rode it in Canada, with very good roads, but they said it was a perfectly original from USA. I was not complaining about the very hard seats, or the lack of space, because they were meant for children... But the LACK of suspension! someone told me it was for safety... I imagine...
I like the visual feel of this. They are not as bad as you would think, at least not for kids who don't have all the back and other problems we do. I rode on them quite a bit when I was young. It probably doesn't help that NYC has bad streets. ~BV~
