Many of the people who ride bicycles on the sidewalks at SJSU do so in ways that risk serious injury to themselves and others. Cyclists riding with no hands are unable to take evasive action if a pedestrian, cart or disabled person steps into their path. Usually cyclists who ride like this way are not wearing helmets.
This bike position is especially prone to falling. These cyclists, as well as endangering others, risk head injuries that could kill them or leave them permanently disabled.
