Baby DS - advice needed

[Elefant]

My son turns 16 next year so, I think, he can ride a 125 (legally) from February.
He's REALLY keen on a small "DS" - any suggestions?
Realise this is going to be something fairly slow and requiring determination to ride any distance!
Will have to be street legal, though...
