Jane Powertwin Pro Tandem  £550.00

As the only 3-wheeler tandem on the market to have a 360° front swivel wheel with disc brake, the Jané Powertwin Pro offers ultimate control and safety, particularly on hilly terrain or steep streets. It’s a practical option for active parents who want to get out and about with a newborn and a toddler, or twins.

i've used three different tandems and this is the only one i kept, it's durable and so easy to steer and push has a really tight turning circle and even with two children can be pushed and steered easily with one hand folds as small as a conventional single pushchair. very large front seat and the car seat can be used back or front so is suitable for twins right from birth or your larger child can sit in the back. Thorougly recommend. A+++++

It's very lightweight compared to the other double pushchairs I tried when I was expecting.
Front seat reclines enough to let a toddler sleep comfortably.
Quite compact for a tandem once your baby can sit properly in the back.
Can be used with an infant carrier to make a travel system for a baby and toddler on the front or back seat and with two infant carriers to make it suitable for twins.
The hand brake. A couple of people have had a chuckle about this asking me when i would ever need a disk brake on a pushchair however i have to say for me it is actually a godsend. Living somewhere that is supposedly flat (norfolk) i have a surprising amount of hills near my house...I grant you that they are not mountains but when you load up two small kids and all thier kit into a pushchair thats never going to be as light as a single (and then you add onto that another baby bump) you will silently thank whoever put it there. It saves me jogging after a front heavy pram - that is far too much like strenuous exercise.
