Xtracycle freeradical conversion kit with some child carrying accessories? You could go for a Weeride and a Hamax combo, may be a bit top heavy. Trailers are great but ours is a pain on the nursery run as bike paths round here are not very trailer friendly (narrow barriers etc.)
Thanks mr.blobby, I think that xtracycle is so close in price to say, a ute, that I would rather have a dedicated bike, which might be useful for something else, rather than taking a bike out of commission.
I never thought about a weeride/hamax combo. My only worry would be that it wouldn’t be as stable as the bigger utility bikes, and I could see it needing a big stand fitted to get the two on and off.
Lardman, T1000, I think the yaba is out of my budget, but definitely looks the part. I can’t see them for anything less than £1600, but that’s an electrical one.
