If the bicycle is stolen, give this number and a description of the bicycle to the police. This will help them ﬁ nd the bicycle.

• There must be at least 1 inch (2.5 cm) of clearance (1) between the highest part of the top tube (2) and the crotch of the rider with tires properly inﬂ ated.

• The minimum leg-length for the rider is the highest part of the top tube plus one inch (3).

Warning and Safety Information

Your Bike

The word “WARNING” is before personal safety instructions. If you do not obey these instructions, injury to the rider or to others can occur.

Rules of the Road

WARNING: Failure of the rider to obey the following “Rules of the Road” can

result in injury to the rider or to others.

• Obey all trafﬁ c regulations, signs, and signals.

• Always wear a bicycle helmet that meets safety standards, as well as local safety standards.

• Ride on the correct side of the road, in a single ﬁ le, and in a straight line.

• If possible, avoid riding at night, dusk, dawn and any other time of poor visibility.

• If you must ride at night or at time of poor visibility:

• Purchase, install, and use a headlight and taillight.

• Headlights are required by all states for nighttime riding and taillights are required in some states.

• Battery-powered lights or ﬂ ashing safety lights are also recommended.

• Make sure the reﬂ ectors of your bicycle are correctly positioned. Do not remove the reﬂ ector or replace the reﬂ ectors with lighted devices that look similar to reﬂ ectors.

• Wear light-colored or reﬂ ective clothing, such as a reﬂ ective vest and reﬂ ec- tive bands for your arms and legs.

• Use reﬂ ective tape on your helmet.

• Do not let anything cover the reﬂ ectors.
