I'm all for kids on the bike within reason- I used to take my youngsta a mile or so to preschool on the Ag-bike on a dirt road but he sat in front and we didn't go fast (much)...on the back is fine if they can reach some footpegs, but having anyone strapped on is totally dangerous and shouldn't happen- maybe all fine but in the 'unlikely event of a mishap', I don't care to think about it
