Standover Height
When selecting a new ebike, the correct choice of frame size is a very important safety
consideration.
Standover height is the basic element of
ebike tness. It is the distance from the
ground to the top of the ebike frame at the
point where your crotch is when straddling
the ebike with both feet at on the ground.
There should be a clearance of 1 inch to 2
inches (25.4 mm to 50.8 mm) between your
crotch and the top tube of the ebike.
If your crotch touches the frame, it indicates
that the ebike is too big for you.
To check for the correct standover height,
straddle the ebike while wearing the kind of
shoes in which you will be riding,and bounce
vigorously on your heels.
Saddle Position Adjustment
Small changes in saddle position can have a substantial effect on performance and comfort. To

Off-road Riding
Off-road riding is very different from riding an ebike on the road. It involves many variables such
as constantly changing traction,obstacles, changes in line of sight, uphill,downhill, soft surfaces,
dry surfaces, and wet surfaces. The variable conditions and hazards of off-road riding require
focus, concentration, strength, tness, and learning to read the trail. Ensure that you have the
appropriate skills when riding off-road and wear appropriate safety gear. Do not ride alone in
remote areas.
Taking a rider weighing 176.4 lbs (80 kg) riding off-road at an ambient temperature of 77℉ (25℃)
as an example. When engaging the PAS to propel the ebike forward, the ebike can ride uphill with
a maximum incline of 8° to 10°.
NOTE The maximum slope range available for the ebike may vary slightly
depending on the weight of the rider and the ambient temperature, and
is subject to the actual situation.
Hot or Cold Conditions
Riding, parking, or storing the ebike in excessively hot or cold conditions can cause damage to
the display and other components. Do not park or store the ebike in direct sunlight for extended
periods. For more information on safe and recommended temperature ranges for your battery,
refer to
“Battery”
.
Low-visibility Conditions
Riding at night/dawn/dusk or in other low-visibility conditions such as fog, rain, mist and snow
is dangerous. It is harder for a rider to read signs and identify and respond to hazards, and also
harder for others to see and avoid you,increasing the risk of accidents,serious injury or death.
Slippery and uneven surfaces will compound the risk. Avoid these conditions when possible.
Should you have to ride in low-visibility conditions, taking the safety precautions below can
reduce the risk to some extent.
■Ride slow.
■Stay alert. Ride defensively and expect the unexpected.
■Avoid dark areas and areas of heavy or fast-moving trafc.
■Wear reective or light-colored clothing to get the attention of approaching motorists,
pedestrians, and other trafc.
■If possible, ride on familiar routes.
■Ensure that the front and rear lights are functioning correctly and unobstructed.
■Ensure that the front and rear reectors are correctly positioned and securely mounted, and
are not blocked by any foreign objects.
Extreme Riding

Wet Weather Riding
Wet weather impairs traction, braking, and visibility, both for the cyclist and for other vehicles
sharing the road. The risk of an accident is signicantly increased in wet conditions. In wet
weather, extra care is required when riding the ebike.
WARNING
!Riding in wet conditions involves slippery hands, feet, and riding
surfaces,which greatly increases your risk of accidents,serious injury, or
death. Low-visibility conditions such as night, dusk, dawn, fog, mist, rain,
or snow will compound the risk of injury or death.
If you must ride in wet conditions, taking the safety precautions below can reduce the risk to
some extent.
■Stay alert. Ride defensively and expect the unexpected.
■Ride slower to better control the ebike in slippery conditions.
■Brake earlier as it will take longer to slow down than in dry conditions.
■Increase your visibility according to the safety precautions in
“Low-visibility Conditions”
.
