Jumping – why do people twitch the front wheel and swing the back end?
Watching Pinkbike videos – really I have nothing better to do on a Saturday evening – I notice that everyone is flipping the front wheel and hip swinging the back end and then landing on the front wheel. Any reason for this? Is it just aesthetics? Or is it aerodynamics? Should I be trying it?Posted 3 years agoSpeederSubscriber
Because it feels great (even if sometimes it looks terrible) a “whip” is one of the easiest and funnest things to do as no limbs need to be removed and got back into place before landing. They can look terrible if the rider just pushes their feet sideways and you do see a lot of that, especially with the clipped in.Posted 3 years agosockpuppetSubscriber
In motocross, the Bubba-Scrub (looks a lot like a whip) is a good way killing height over a jump.
If you kill the height/squash the jump more of the energy stays as kinetic energy rather than gravitational potential energy: you go flatter, and faster, and motocross is all about winning!
There’s some great bubba-scrub videos on YouTube: guys scrubbing well before the lip.
OTOH, with MTB, it’s mostly styling it up, coz they can.

Air time is ‘dead time’ when you’re racing, so you either suck up or ‘pump’ the jumps/tabletops to keep your wheels on the ground and pedal, or if it’s a steep take off that will Def launch you, you scrub it to keep as low/flat as possible.rp16vMember
i find it helps me spot and control the landing better also if your going fast and come a cross a short table or double u can avoid a flat landing and keep a smooth line to the next setup by scrubbin
also seen allot on hips which i find really fun
also looks boom(youth attempt) if the person behind is recording 8)Posted 3 years ago100mphplusMember
I think they look crap, and do not serve any purpose ..
They do serve a purpose. Yes some riders do them all the time as that’s what the spectators heckle for, but the guys winning the races do them too as they are the fastest way over jumps. Physics is great sometimes 😉Posted 3 years agoYETIboyJAYMember
It all depends on the situation. Some whips are actually scrubs, a way of getting over a jump without loosing speed. Other times you whip to show off or set you up for a better position on landing.
I ride DH and MX and find I have to let the bike move and flow in the air or it just feels dead- like the bike is controlling me, not the other way round.
It’s a weird one but if you are a jumper, you’ll understandPosted 3 years agoiffoverloadMember

yes, “scrubbing” serves a purpose, whips? more just for fun I’d say. 😉Posted 3 years ago
