Cleaning and Storing Your Smart
Use a soft, wet cloth to wipe the mainframe clean. Hard to remove dirt can be scrubbed with a toothbrush and toothpaste,
then cleaned with a soft, wet cloth. Scratches on plastic parts can be polished with extra fine grit abrasive paper.
NOTE
Do not wash your Smart with alcohol, gasoline, acetone, or other corrosive/volatile solvents. These substances may damage
the appearance and internal structure of your Smart. Do not wash your Smart with a power washer or high pressure hose.
WARNING
Make sure the Smart is powered OFF, the charging cable is unplugged, and the rubber cap on the charge port is tightly
sealed before cleaning; otherwise you may expose yourself to electric shock or damage the electronic components.
Store your Smart in a cool, dry place. Do not store it outdoors for extended periods of time. Exposure to sunlight and
temperature extremes (both hot and cold) will accelerate the aging process of the plastic components and may reduce
battery life.
Tire Pressure
Inflate tires to 35–50 psi. Inflate both tires equally.
Battery Pack Maintenance
Do not store or charge the battery at temperatures outside the stated limits (see Specifications). Do not discard or destroy
the battery. For more battery information, refer to the sticker on the battery itself, located on the bottom of the Smart. Refer
to your local laws and regulations regarding battery recycling and/or disposal.
A well maintained battery can perform well even after many miles of riding. Charge the battery after each ride and avoid
draining the battery completely. When used at room temperature (70°F [22°C]) the battery range and performance is at its
best; whereas using it at temperatures below 32°F (0°C) can decrease range and performance. Typically, at -4°F (-20°C)
range can be half that of the same battery at 70°F (22°C). Battery range will recover when temperature rises. More details
are available in the App.
NOTE
Typically, a fully charged battery should retain charge for 120-180 days in Standby Mode. A low-power battery should retain
charge for 30-60 days in Standby Mode. Remember to charge the battery after each use. Completely draining the battery
may cause permanent damage to the battery. Electronics inside the battery record the charge-discharge condition of the
battery; damage caused by over-discharge or under-discharge will not be covered by the Limited Warranty.
WARNING
Risk of fire. No user serviceable parts. Do not attempt to disassemble the battery.
WARNING
We strongly recommend against riding when the ambient temperature is below 23°F (-5°C) because low temperature will
limit the maximum power/torque. Doing so could cause personal injury or property damage due to slips or falls.

[1] Typical Range: tested while riding under full power, 154 lbs (70 kg) load, 77°F (25°C), 9.3 mph (15 km/h) average speed on
pavement.
[2] Continuous Discharge Power: tested while under full power at 77°F (25°C). The value changes with temperature and remaining
battery capacity. For example, the continuous discharge power drops to ~80% of the maximum value at 10% remaining battery
capacity, and the continuous discharge power drops to ~70% of the maximum value at 32°F (0°C).
