I have two kids - nearly 2 and nearly 4 yo - and they are both quite tall and heavy for their age (upwards of the 90th centile on both). I would like to cycle them to pre-school/school and I'm trying to decide on the best option for doing so. I don't want seats, I'd like a trailer or a cargo bike but there is a massive price difference. I'd love to go for the cargo bike but at £1000 - £1500, I'm obviously a little hesitant! I'd go for the trailer but I'm worried about height/weight restrictions. Any advice, pointers, experiences?
