I have added some hints to the article on obstacle hopping. I include it below
for your perusal and comments.
Ride over 10x10cm obstacle
Ride up to the curb at a good speed.
When you hit the obstacle give the pedals an extra push to go up and over.
Ride toward the obstacle.
When you are close, and the pedals are horizontal, stand on the pedals and
jump over the obstacle.
Ride up alongside the obstacle.
Jump up and down a few times, then make a big sideways jump to go over
Approach at slow speed
Stop against the obatacle, standing on the pedals with a gap between the
unicycle’s seat and your seat.
Grabbing the seat handles, ride/pull yourself up and over the obstacle.
Notes and Hints:
Method #1 was the way the developers of the skill level list intended that
riders perform this trick. Many examiners just look to see if you can go from
one side of the obstacle to the other, regardless of method. Check with yours.
With methods #1 and #2, you need to have the pedals more-or-less horizontal when
you hit the obstacle. You can practice this by putting the wheel against the
block with the pedals in the correct position, rolling the unicycle backwards a
ways, getting on and riding to and over the obstacle. If you arrive at the block
with the pedals in the wrong place you might as well turn around and go back.
My (Terry) current method (#4) is to jump before I get to the obstacle. I used
to be only able to do this when my pedals were level and the right one was
forward. I can do the left now as well, but still tend to miss it reasonably
often. The hardest part about this is judging when you should take off, but you
learn to make slight adjustments in your approach angle so that your pedals are
where you want them.
One way to practice this sort of jumping is just to ride along and hop over a
line on the ground (or even do it with no line). When your pedals get level,
the back one stops you and you pop up. I only hold the seat at the front.
Eventually you can do this with every half revolution of the wheel. A more
advanced practice is to ride along a paved sidewalk and try to jump over every
line (or every second line to begin with). This forces you to make decisions
about when to jump
(i.e. with what foot forward).
A 20" wheel goes 5 feet per revolution, so you may end up having to take off 2
feet or so from the obstacle (though in practice this wont happen as you’ll
learn to anticipate this and change the approach angle).
I prefer this method as you never stop and it’s probably smoother and nicer
looking than the ride into the gutter and then heave up method.
