Here, we have seats on the front and back of the bike (normal, not electric ones...) for the kiddie transport... it works well until they are around 5... even then, it's a pretty big extra weight to lug....

In the larger countries, this isn't really a great solution... it is trading time for footprint/moneysavings.... Still, I would like to see how far this bike can go... it is rated for 80-120kms on this battery... so, I should be able to go a fair bit further!
