Not sure if I'm being daft (it wouldn't be a first), but I'm finding myself strangely attracted to getting a cargo bike a la Surly Big Dummy or Yuba Mondo for our boys. We've pulled them along in a Chariot since they were about 4 months, but now that they are pushing 20kg each, that's proving a bit of a challenge for MrsB (and me, if I'm honest). It would be for dropping them off at nursery, and in time, school, then pootling on to work.
Ideally I'd like it to be able to be ridden by either of us, which poses another issue as I'm 6'3", whilst MrsB is 5'8". Some of the cargo bikes, such as the Mondo look to be good for a reasonable range of heights, as they have a pretty slack ST, and long post, so the ETT extends. Some, like the Surly don't seem to cater for this.
So, does anyone ride this sort of bike for hauling their kids? How practical are they for day to day stuff? What are they like on hills?
