Bicycle Fact Sheet

The U.S. Consumer Product Safety Commission estimates that over 600,000 persons suffered bicycle-related injuries serious enough to require hospital emergency room treatment in 1994. Here are some typical cases:

"Karen applied her hand brakes and lost control of her bicycle. She went down an embankment into a creek, and fractured her shoulder."

"As Jimmy was riding his bicycle downhill, the front wheel of his bicycle suddenly became loose and twisted. Jimmy lost control, fracturing his knee."

"Bob was riding a bike without a chain guard when his foot caught between the pedal and chain. He fell, suffering a concussion and skull fracture."

"Michele was riding her bike alongside a friend's. As her friend moved his bike to the right, the two front wheels collided, causing Michele to fall. She suffered a concussion and fractured a wrist."

These case histories illustrate some major accident patterns associated with bicycles. They are:

* Collision with a car or another bicycle.

* Loss of Control -- This occurs because of a number of factors, including: difficulty in braking; riding too large a bike; riding too fast; riding double; stunting; striking a rut, bump, or obstacle; and riding on slippery surfaces.

* Mechanical and Structural Problems -- These include brake failure; wobbling or disengagement of the wheel or steering mechanism; difficulty in shifting gears; chain slippage; pedals falling off, or spoke breakage.

* Entanglement of a person's feet, hands, or clothing in the bicycle.

* Foot slippage from pedal.

To make bicycles safer, the U.S. Consumer Product Safety Commission developed a mandatory safety standard for bicycles to help eliminate injuries due to mechanical and structural failures.

The CPSC regulations establish strict performance and construction standards for the brakes, wheels, steering system and frame. They require reflectors on the front, back, sides and pedals to make bicycles visible at night; require elimination of uncovered sharp edges and jutting parts; and require brakes on bicycles with seat height of 22 inches or more. New bicycles are required to meet the standards.

The U.S. Consumer Product Safety Commission offers the following safety tips when shopping for a new bike or taking care of an old one:

Selecting the Bicycle

* If you're buying a bicycle for a child, choose one to fit the child's size today, not one he or she will "grow into" later.

* A bicycle should suit the rider's ability and kind of riding.

* Check hand and foot brakes for fast, easy stops without instability or jamming.

* Avoid slippery plastic pedals. Look instead for rubber-treated pedals, or metal pedals with serrated rattrap edges or with firmly attached toe clips.

Using the Bicycle

* Always wear a helmet to help prevent head injuries. CPSC is setting a new mandatory standard for bike helmets.

* Observe all traffic laws and signals, just as automobiles must do. Graphic of a bicycle with safety features pointed out

* Don't ride double or attempt stunts.

* Ride near the curb in the same direction as traffic.

* Find alternate routes, rather than ride through busy intersections and heavy or high-speed traffic.

* Walk -- don't ride -- your bicycle across busy intersections and left turn corners.

* Avoid riding in wet weather. When wet, handbrakes may require a long distance to stop.

* Avoid riding in the dark. If you do, be sure the bike is equipped with a headlight, a taillight and reflectors. Apply retro-reflective trim to clothing, or wear reflective vests and jackets.

* Avoid loose clothing or long coats that can catch in pedals or wheels. Leg clips or bands keep pants legs from tangling in the chain.

* Avoid crossing raised sewer grates.

Net Pegs (Anchor Types)

These tapered, metal stakes should be used to secure only the NET to the ground. Net pegs should NOT be used to anchor the movable soccer goal 6. Guidelines for Goal Storage or Securing When Goal is Not in Use The majority of the incidents investigated by CPSC did not occur during a soccer match. Most of the incidents occurred when the goals were unattended. Therefore, it is imperative that all goals are stored properly when not being used. When goals are not being used always:
a) Remove the net,
b) Take appropriate steps to secure goals such as:
1) Place the goal frames face to face and secures them at each goalpost with a lock and chain,
2) Lock and chain to a suitable fixed structure such as a permanent fence (see Figure 4.2),
3) Lock unused goals in a secure storage room after each use,
4) If applicable, fully disassemble the goals for seasonal storage, or
5) If applicable, fold the face of the goal down and lock it to its base.

Semi permanent (Anchor Types)

This anchor type is usually comprised of two or more functional components. The main support requires a permanently secured base that is buried underground. One type (3.2a) of semi permanent anchor connects the underground base to the soccer goal by means of 2 tethers. Another design (3.2b) utilizes a buried anchor tube with a threaded opening at ground level. The goal is positioned over the buried tube and the bolt is passed through the goal ground shoes (bar) and rear ground shoe (bar) and screwed into the threaded hole of the buried tube.
