SAFETY INFORMATION02

Tailwind E-Bikes User Manual
A. ALWAYS WEAR A HELMET
Helmets signicantly reduce the number and severity of head
injuries. Always wear a helmet that complies with your state
laws when riding your Tailwind E-Bike. Check with your local
police department for requirements in your community. Make
yourself more visible by wearing bright reective clothing. Keep
your reectors clean and properly aligned. Use head and tail
lights in reduced lighting conditions. Wear sturdy shoes and eye
protection. Also check your state laws concerning other protective
gear that may be required when riding your Tailwind E-Bike.
B. KNOW YOUR TAILWIND E-BIKE
Your new Tailwind E-Bike incorporates many features and
functions that you may be unfamiliar with. Read this manual
thoroughly to understand how those features enhance your riding
pleasure and safety.
C. RIDE WITHIN YOUR LIMITS
Take it slow until you are familiar with the riding conditions, as
traction can be greatly reduced and brakes become less eective.
Never ride faster than conditions warrant or beyond your riding
abilities. Remember that alcohol, drugs, fatigue, and inattention
can signicantly reduce your ability to make good judgments and
ride safely.
D. KEEP YOUR E-BIKE IN SAFE CONDITION
For your safety and enjoyment, and to ensure a long life for your
Tailwind E-Bike, inspect and maintain your E-Bike regularly.
Follow the inspection and maintenance guidelines throughout this
manual. Check critical safety equipment before each and every
ride.
