Grabbed one of these the other week for the young bloke.Its a ripper.He can ride his bike when he wants,if he gets tired or we go on a busy road I tow him.Nothing extra to carry in the ct as it all telescopes back onto the lead bike.

Better than one of the ones with only the back wheel, give the kids their own freedom when they want.
