I may be old fashioned, but I thought that bikes were for riding. If I want to jump I'll get a parachute.
So do you get off the bike when the trail gets technical? Do you brake as hard as you can down every hill? Get off when a little wheelie would get you over a trail obstacle?
At least have a try, you wouldn't beleive how much fun it is.
I rode BMX for 6 years and never got that far off the ground tbh (did a bit of park and street but mainly flatland) but the day I did a no footer over a box jump I'll remember forever.
I just love it when you're steaming down a hill and you spot a little water bar or a little bump in the trail you can use as a kicker. Suddenly, and for a fraction of a second, the noise of the trail disappears and maybe you can hear your freewheel buzzing. Then you land, taking up the impact with a little flexing of the legs and arms, and you're away…!
You can use the airtime skills in EVERY trail!
