Dear Doug,
Possibly you're thinking of a unicycle?
When you tip over forward on a high-wheeler, you hit the handlebar
with both thighs and do a face plant.
Note the handlebar just above the rider's knee in the picture. Most of
the 25 to 50 pound high-wheeler is right behind him, 50 inches high,
and about to teach him why safety bicycles earned their name.
There were lots of bizarre patents for high-wheeler handlebars
intended to get around this problem, but none of them worked.
Many handlebar patents involved schemes to have the bar detach and
break away under the impact of the rider's thighs. The rider ended up
with a loose handlebar in his hands (or flying up into his face) and
the high-wheeler was still tangled between his legs.
One weird design had the handlebar curved in two U's _behind_ the
rider's legs, so that he could leap forward unimpeded. One problem was
that he wasn't leaping, he was toppling unexpectedly. Another problem
was that this placed a pair of handlebars _behind_ him, still coming
forward to crash into him from behind. Finally, it made mounting the
high-wheeler next to impossible:

These absurd inverted ape-hanger bars drop below the front axle to
provide theoretical clearance in crashes:

You can imagine what would happen to such silly bars in any real
crash.
Here's a page with four highwheelers with more detailed pictures than
anything I've ever seen:

Click on a high-wheeler, choose the English version, and enjoy dozens
of detailed close-ups of the the parts.
