Pretty cool none the less. Losing the front is always a fear

Great for highsiding you instead, or blasting you into oncoming traffic.

Got to be a spoof? How much force needed to catch a cornering 250kg motorcycle when grip goes to zero? The first slide tucked the front but the stabilizers caught it... The last one without stabilizers wasn’t really a slide at all.

Shown on a damp patch about 4 ft wide (so grip returns pretty quickly)... I think it’s either a spoof or an early concept that will come of age about the same time as flying bikes.

This paper analyses and decomposes the forces needed for cornering on a bike, the lateral tyre load is actually fairly reasonable: http://www.iaeng.org/publication/WCE2010/WCE2010_p...

Forces are up to the order of 150Nm, or the equivalent of a 15kg (and a smidge) weight, for turns at sensible speeds. Times of absolutely zero lateral grip are pretty rare, so you can restore a little of that force back for the fastest cases. You could also consider that for a small patch where control is lost you don't need 100% of the original radius lateral force - anything which will slow the lowside and allow control would give you a fighting chance.

Getting a small gas thruster to exert a 10kg force isn't all that difficult, it's just the complexity of recognising and timing it correctly through the IMU. For example, an airbag charge exerts over 750Nm in a tiny space of time.

Interesting that the jet is on the outside pushing below the mid point on the bike, rather than the opposite side, sitting above the mid point of the bike. Surely the effect of pushing the tail of the bike "up" would be higher than pushing the "wheels" of the bike "down". Or is part of the idea to load up the tyres and push them back on line?
Maybe they will develop it do have one each side?

Interesting if potentially redundant tech.

This could only be an April Fools joke, I just don’t get it. However, if it isn’t and it genuinely does work, then that’s ace, we get a free pass. How much more will we push with it? ABS, TC etc in cars and bikes just got used as a performance enhancer, not a safety feature.

It’s lowside, not slide.
