Fitting the Rider to the Bicycle

Introduction

To determine the correct size of bicycle for the rider:

• Straddle the assembled bicycle with feet shoulder width apart and ﬂ at on the ground.

• 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

Meanings of Warnings:

a This symbol is important. See the word “CAUTION” or “WARNING” which

follows it. The word “CAUTION” is before mechanical instructions. If you do not obey these

instructions, mechanical damage or failure of a part of the bicycle can occur.

Introduction

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

• Adult assembly is required.

• Continuous adult supervision is required.

• Do not add a motor to the product.

• Do not tow or push the product.

• Do not modify the product.

• Replace worn or broken parts immediately.

• If anything does not operate properly, discontinue use.

Freewheel Brakes

WARNING:

• Some models do NOT have a foot (pedal) brake.

• Ensure your child understands and can operate the hand brakes.

• Always use both hand brakes when stopping the bike.

• When stopping, apply front and rear brakes evenly.

• An unstable condition can occur if the front brake is used too hard resulting in injury to the rider or others.

Reﬂ ectors

WARNING: For your own safety, do not ride the bicycle if the reﬂ ectors are incorrectly installed, damaged, or missing. Make sure the front and rear reﬂ ectors are vertical. Do not allow the visibility of the reﬂ ectors to be blocked by clothing or other articles. Dirty reﬂ ectors do not work well. Clean the reﬂ ectors, as necessary, with soap and a damp cloth.

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 CPSC safety standards, as well as local safety standards.

Rules of the Road - continued

• Always wear shoes.

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

• Bikes under 20” not intended for use on roads.

• Avoid riding at night, dusk, dawn and any other time of poor visibility.

• 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.

• Do not let anything cover the reﬂ ectors.

• Use extra caution in wet weather:

• Ride slowly on damp surfaces because the tires will slide more easily.

• Avoid these hazards to prevent loss of control or damage to your wheels:

• Be aware of drain grates, soft road edges, gravel or sand, pot holes or ruts, wet leaves, or uneven paving.

• Cross railroad tracks at a right angle to prevent the loss of control.

• Avoid unsafe actions while riding.

• Do not carry any passengers.

• Do not carry any items or attach anything to your bicycle that could hinder your vision, hearing, or control.

• Do not ride with both hands off the handlebar.
