Any idea where to buy one please. My bicycle shop, North Wheels only has it on special order.

Piet,

Rear Baby seat; Jacky, Song, Chaitawat have them in stock. 800 to 1500 baht depending on the brand.

Front baby seat is easy to find in Europe but not here.

I have one (from Europe) at home but it can only be used for an old head set and front fork with tread.

It can not be used on a mountain bike with a A head set.

the two biggest bike shops ive seen in chiang mai are here .... try asking there

good luck ... dave2
