Just curious: why does the HP Velotechnik site show photos of
helmetless riders?

Anyone actually fell of a 'bent? Seems like a harder thing to do, no?
I mean, don't you just put your foot down -- the body's so close to the
ground as it is....

I'm still not sure how styrofoam is supposed to protect the head...why
not wear a real helmet?

Surely someone manufactures a lightweight helmet that's stronger and
lighter than styrofoam?
