I have seen the Pear but it was way back in October now when I looked at it and I can't really remember how big the seats etc were on it, sorry!
I can tell you that on the Peach they go more narrow where the feet go in the seat or carry cot. So its more streamlined and seems to fit together better than the Pear, its not as bulky and there seems to be more space between the 2 seats. The hood bit on the seat is adjustable you can higher it up if you have a tall toddler. I'm just looking at the pictures of the Icandy Pear now trying to jog my memory....my toddler is 2 years old next month and he's about the height he is supposed to be if not a bit taller and he doesn't look too big for the seat he looks fine if that helps you at all.
I do think it is a lot better than the Pear they have made some good improvements.
The brakes are different its a lot easier to put on and off. The frame that the seats clip to convert it to a double are less than half the size of the frame needed on a Pear. Its really small no where near as big as the Pears. Its that small that I just leave my adapters for the car seat and the adapters to turn it into a double in a shopping bag in the boot of my car so I don't forget them.
I struggled to get the hang of collapsing the pear but with the Peach I've got the hang of it no problem.
I think if that price they have given you includes all the seats/carry cot, adapters etc then its well worth it. Your getting a lot of kit there for your money and its good quality I am a firm believer you get what you pay for!
I have a VW Golf and it all fits in my boot fine, and I don't find it heavy to lift in and out at all and as said before I'm only 5'2 so I'm not the strongest person, I'm afraid I don't know what the weight is of it but I do know that its lighter than the Pear.
I've looked at all others doubles, loved first wheels but wouldn't fit in all doorways, I hate how the new born in phil and teds look like they are slide in the shopping basket underneath the toddler. I wouldn't hesitate in buying a ICANDY if I didn't have the peach now and I would of bought the Pear. For me it ticked all my boxes,
It wasn't too high - some push chairs i tried i couldn't see over them to see where i was pushing!
I can adjust the handle height
Its sturdy
The toddler has a proper seat
The newborn is in a carry cot - I was early with my first and he was a small baby so I also think its better for a baby to be in a carry cot and then they are comfortable.
Good sized shopping basket which you can always access
It can be used as a single or double push chair
Its easy to push
It can fit in shop doorways! so many shop door ways arent wide enough for a twin.
You can also fit a maxi cosi car seat to it if you want to but like I said before I prefer mine to be in a carry cot or seat so I wasn't really bothered about that feature.
I hope all that info helps you
