I've got a Burley Honey Bee. I take my now 3.5y/o and 1y/o for rides in it. I take them only to flat bike paths. I probably wouldn't take them on gravel or stone or anything like that as it might be too bumpy. If you're in doubt then get the suspension or go to a place that has both and see if you can take a test ride and ask the kids if one was noticeably better than the other.
