    24" fatties might make sense for big people, too. If you are going for float, width is what matters. A fatty tire would make the total diameter in the territory of a 26" regular mtb knobby tire, which is pretty tried and true. 24" would have less angular momentum than 26" of course, just like 26" vs 29". And with fatty tires, angular momentum is a big deal.

    The energy you have to put into the wheels is the same - for a smaller wheel you need to spin it faster.

    I did contact On-One recently to enquire about availability of the Baby. They did say that delivery has been pushed back to after the first of the year but it is in production. My son should just fit it come springtime.

    You can accelerate a smaller wheel faster. A bigger wheel is good when you can keep going at steady speed.

    I very much like to be able to accelerate on my local trails.

    +1 I'm going to buy one because of this.

    I have a 17" Fat Sand Bike, with geared hub it's a 12kg 29" wheelset. Riding cycle paths it rewards you by keeping in tall gear and cranking to keep the momentum up, rather than spinning on the flat at least. No choice for climbs, spin or die rolling backwards =D I have a 20" wheeled Cannondale Hooligan like a BMX that on the same commute is at the other extreme of wheel sizes I have, and same small versus big wheels it climbs like a billy goat and brakes like a demon compared to big wheels, but requires more input on the flat top cruise speed than the big.

    The 29" fatties get more float with a larger contact patch that extends longitudinally as well as with width. You will get as much contact patch bang for buck by diameter increase than width increase.

    I have to briefly die climbing small steep paved dunes to get to the beach and back home, and I don't ride along the beach at speed, so an easier climbing smaller wheeled baby fatty would be a nice addition. The bonus of everything being smaller and lighter to lift up sandy steep twisty stair access, rock outcrops, etc. etc. will be nice too. Broader use as a fat MTB for trying other trails I'd choose it also.

    It's still the same legs that have to do the work at the end of the day though. I just received an On-One delivery of two big wheel boxes of tyres and bits that I wish was a Baby Fatty to test out... patience is the 2014 fat bike virtue =D

    I take it you've never ridden in the snow. Fresh snow.

    The reason that On-One is marketing this bike for shorter riders is that it is a smaller bike. I cannot see any conditions in which I would chose a 24" fat bike when my spideresque physique allows me to fit a full size bike. I want one of these for my kid since she will not fit on a 13" frame Mukluk. This bike is a great idea because less geometry concessions need to be made to fit a fat tire into a small frame if the wheels have smaller diameter. Also, smaller riders tend to be lighter and need less float because of it, so they can afford to lose some wheel footprint.
    I have ridden a 29+ wheel on snow and it works, but it is not as good as a LM with 3.7 inch tires. It is way better than 50mm rims with a 3 inch wide tire. To pretend that spinning a 24" wheel faster will make it anything like a 26" wheel is pure delusion.

    SO, you are of the opinion that bigger is better?
    Or that if bigger is better for you, it is better for everyone?

    Awesome!!! When you have time, can you by chance measure standover and wheelbase for me?

    Those do not look like Floaters as the description reads and picture shows. What are they, Missions?
    Disappointing.

    Uhm, well, he thinks it's heavy. I'm not one for weighing stuff really.
