GENERAL WARNINGS
Like any sport, cycling involves risk of injury and it is the rider’s responsibility to assume
potential risks and injury involved when riding. By choosing to ride a bicycle, you assume the
responsibility for that risk. You need to know and practice the rules and safety regulations
of riding this bicycle. Proper use and maintenance of your bicycle reduces risk of injury.
Check your local, state, or country regulations for electric bike laws. For example, check the
minimum age for using an electric bike, as this differs in various regions.
Riders must have the physical condition, reaction time, and mental capability to ride and
manage traffic, road conditions, and sudden situations. Also, respect the laws governing
E-Bike use in accordance with each region. If you have an impairment or disability (i.e. visual
impairment, hearing impairment, physical impairment, cognitive/language impairment,
seizure disorder, etc.), consult your physician before riding any bicycle.
• When riding, obey the same road laws as all other road vehicles, including
giving right of way to pedestrians and stopping at red lights and stop signs.
• For additional information, contact the road traffic authority, police
department or Department of Motor Vehicles in your state or country.
• Use correct hand signals to indicate turning or stopping.
• Concentrate on the path ahead. Avoid potholes, gravel, wet or oily roads,
curbs, train tracks, speed bumps, and other obstacles.
• Walk your bike across all train tracks.
• Expect the unexpected, such as opening car doors or cars backing out of
driveways.
• Be aware at intersections and when preparing to pass other vehicles or other
cyclists.
• Familiarize yourself with all the bike features. Practice using the brakes and
throttle.
• If you are wearing loose pants, secure the bottom using leg clips or elastic
