Joyful, Berlin, LiewLian & Cheeerful_Mum,
The stroller is not heavy at all. And it is very easy to assemble. Only need to fix the 3 wheels then , it's on the go. Folding wise also easy. Height wise for me & hb is ok, for my mom (1.6m) abit too huge, cos height not adjustable. It cost US$299, its called the BOB Sport Utility Sport Stroller. They have the D'lux and Ironman Series. The wheels are 16inch each. Bear in mind, this stroller can't be used in our shopping malls, it is meant for outdoors and it can take hard rides. The front wheel however,does not swivel, if you want a swivel front wheel it cost US$360, its called the BOB Revolution.
Note: this stroller is double the size of the Quinny and all other strollers. That explains why my mum looks dwarfed when pushing it.
Another brand to consider is called Dreamers Design, their Slingshot / Rebound model is very good as well, and the height is adjustable but it is quite heavy. BTW, I sa another 3 wheeler at Motherworks @ Great Worlwd, its called Mountain Buggy, the front wheel is a swivel wheel & it is very easy to handle & not heavy at all but it cost around S$900 if I am not wrong.
Cheerful_Mum, not sure if UK has it cos' it is a US product but I know Norway, Germany & Sweden ,Canada has it can, ask your hb fren to get it from there and bring it back to S'pore.
Hope my info is helpful for you gals.
