I had a Jane Powertwin for my newborn and 3 year old.
The 3 year old's head didn't fit under the hood and her legs hung down by the front wheel, catching it :( As only the rear chair reclined fully flat, she was in front and the baby in back. Consequently, with the heavier child at the front, the whole wheelchair's centre of gravity is out of kilter and the buggy tipped over when ascending kerbs, inclines, steps, buses, anything. For a more petite woman or someone post- c section, the buggy WILL tip over completely. How this Spanish brand passes CE safety regs I will never know.
Lock the front wheel to possibly prevent this, I don't know. I doubt it. It may react differently with the smaller child in front, but I wasnt willing to wait!
The newborn recline seat at the rear is very good, the hood covers the whole space well.
The raincover is fab, with access windows, and covers entire buggy.
Shopping basket is fab too.
If you are buying secondhand, take some tools and open up the housing around the fork on the front wheel, it will likely be rusty or about to snap, they shear off quickly and again ... over goes the buggy! Online reviews will also back this up.
The air wheels are a nightmare to pump up, you need some kind of adaptor attachment for the pump that comes with it.
Nightmare to fold down and is huge, you'll need an estate or peoplemover whatever they're called type car.
As you can see, I dont recommend it!
The Jane TwinTwo has four wheels and is much more stable.
It's looks funky however and has great colourways. Ever wondered why you rarely see them on the streets and there's so many for sale on ebay? Because mum use them once, rollover occurs and they cant get rid of them quick enough I expect! They're downright dangerous.
No doubt someone else will come along and say what a lot of nonsense they never had these problems, but if their factors were identical to mine then I logically can't see how that is. Just read other internet reviews.
Ultimately, if it fits your lifestyle, a side by side double is much better. I had the Out n about Nipper 360. It was perfect in every way.
