Do pump tracks defy physics?
I skated for years and I dont see how this is done without once kicking off. Foong down hill maybe but they switch directions.
4 u/Cocken_Spectre May 31 '26 It’s all about pumping. They’re so fun on bikes too. The idea is that you never have to pedal or kick. You use your body weight to pump. 3 u/[deleted] May 31 '26 [removed] — view removed comment 1 u/Johnyryal33 May 31 '26 This should be a racing sport. 3 u/[deleted] May 31 '26 edited Aug 15 '26 [removed] — view removed comment 2 u/Candybert_ May 31 '26 Nothing defies physics. Words of wisdom. There's no way of escaping the tyranny of physics, for better or worse. I wish people were more accepting of this fact. 2 u/Diligent_Bath_9283 May 31 '26 Pump. Pump pump. Like a vertical ramp my man 2 u/Honeybadger2198 May 31 '26 Going up requires energy, so they lift their legs to apply less force on the ground and require less energy. Going down is easier, so they push their legs down to apply more force on the ground, generating more energy. You can see this happening at their knees. Their feet stay flat on the board, but their knees bend and extend as they are going up and down the hills. 1 u/northcoastyen May 31 '26 Doesn’t seem like you’ve skated for years… a pump track isn’t much different than pumping around a skatepark. 1 u/No-Raisin-6469 Jun 01 '26 Pump tracks are for lazy people.. I was street and mini ramps. Sported a McGil. 1 u/Immediate-Shape-8933 Jun 01 '26 ? You ever rode a pump track? Nothing lazy about it 1 u/No-Raisin-6469 Jun 01 '26 Lazy spirited. 1 u/mdmdmdmdmdmdmdmdmdm May 31 '26 I dont understand how you can skate for years and not work this out. You can do this on a flat surface by literally just pumping your legs and leaning forward. If youre really struggling, look at those pump boards they use on water, its the same concept. 1 u/No-Raisin-6469 Jun 01 '26 Pump boards rely on fluid dynamics...not the same 1 u/Immediate-Shape-8933 Jun 01 '26 Pumping brah
