Problem   Possible Cause  Solution

charge
Brakes are not adjusted properly
Riding conditions are too stressful
Tires are not properly inflated

Charge the  battery. A new battery should have been charged for at 
least 18 hours before using the motor bike for the first time and up to 
12 hours after each subsequent use.
Check all connectors. Make  sure the charger connector  is tightly 
plugged into the charging port, and that the charger is plugged into 
the wall.
Make sure power flow to the wall outlet is on.
Check all wires and connectors to make sure they are tight.
The  fuse  will  burn  out  and  automatically  shut  off  the  power  if  the 
motor is overloaded.
An excessive overload, such as too heavy a rider or too steep a hill, 
could cause the motor to overheat. Replace the fuse with a new one 
of equal amperage. Correct the conditions that caused the fuse to burn 
out and avoid repeatedly burning out fuse.

Even with proper care, a rechargeable battery does not last forever. 
Average battery life is 1 to 2 years depending on use of product and 
conditions. Replace only with a Razor replacement battery.
Refer to brake adjustment instructions on page 5 of this manual.
Use only on solid,  flat  clean and dry surfaces such  as  pavement or 
level ground.
The tires are inflated when shipped, but they invariably will lose some 
pressure between the point of manufacturing and your purchase. Refer 
to instructions on page 4 of this manual to properly inflate tires.
Make sure you do not overload the motor bike by allowing more than 
one rider at one time, exceeding the maximum weight limit, going up 
too steep a hill or towing objects behind the vehicle. 
Check all  wires around  the motors  and all  connectors to  make sure 
they are tight.
