Apparently, even guys with big legs can find a place.
If I remember my physics, if the earth were to suddenly stop spinning, our momentum would launch us forward at about 1000 mph. It wouldn’t be a slight bump like you see in the commercial.
Bugger the physics – that’s a cool ad. 
But I wanna see all those cute little villagers launched forward at 1000 mph!
Only if we were close to the equator. Here at 45 degrees, it’d be less (cos 45˚ * 1000 = 707 mph?) and at the poles you’d just twirl around a bit.
So the advert isn’t factual?!!!11one
OMG WE’VE BEEN LIED TO!! :eek:
Well, presumably the guy needs to keep pedalling to overcome some friction or resistance which prevents the Earth from otherwise spinning unhindered by conserving its momentum for some billions of years. It might be that when our hero stops pedalling for a moment, the Earth merely begins slowing down, instead of suddenly halting.
To get the little bump, you can imagine that the pedal-stop isn’t smooth, or that the friction or drag that the pedaling overcomes isn’t linear. In fluid drag, for example, there are plenty of situations where the switch between laminar and turbulent flows, or between subsonic and supersonic flows, results in a rapid change in the drag experienced.
Or just the Earth’s clutch is finicky.
