They are too young for a Lambretta or a Vespa, but they might like to be going with the Chad Valley retro electric scooter for kids.
Trading on the classic scooter look of a bygone era, this is a working bike for kids of sorts. By that, we mean it has working headlights and engine sounds, as well as 6V
engine, which hits around 3mph in forward or reverse. Oh yes, has an FM radio too.
