Great, thax, now I know down side whip.
and how about foot jam using back foot/ front foot ?
for a street foot jam whip - jump over the frame, front foot jam, back foot kick the rear wheel around, rotate to front foot direction, after it came around, jump out, catch pedal in air.
but with breaks on trials bike, you can do - break, throw the rear wheel to front foot direction with both foot, back foot jam, after it came around, back foot cross over the frame to catch pedal.
the thing is, in street, without front break, you have to use jam as break. so,
1, you have to jump over frame to break front wheel with front foot, in the same time kick bike around with back foot.
2, you can't cross over to catch pedal, when your foot off front wheel, no more break, lose control over front. so you have to jump out then catch pedal in air.
they are very different skills, different foot, and steps. they must have different names?
I'm doing street footjam whip, but I also ride trial, it's bit confusing, so I'm trying to get it straight.
