Battery Care & Charging
The Ninja battery should be recharged after each and every use. The charger
automatically stops when charging is complete. You can check the level of charge using the LCD display battery meter or the small LED meter on the side of the battery pack closest to the charging
Riding Off-Road and In Wet
We do not recommend riding
the bike in conditions that exceed your or the bike’s ability. Riding in extreme terrain is not recommended and in some cases can void your warranty. You should never exceed 350 watts of power in
loose off road terrain otherwise, you risk damaging the hub motor from overheating or overloading to the electronic system. Wet weather impairs traction and visibility for the cyclist and vehicles sharing the road.
The stopping power of the brakes, traction of tires and grip of the rider's feet on the pedals are all lessened in wet weather. If your feet slip off the pedals, tires lose traction, or the brakes
cannot stop you appropriately it could lead to a fall.
Riding in Hilly
hilly terrain, it is
recommended that users always pedal to assist the bike in climbing up hills. On steep hills, you should never exceed 350 watts of power. This can be accomplished by riding with the twist throttle only partially
applied. While regulating the throttle, watch the watt meter on the display and ensure that you regulate the power output. Never ride up hills which exceed a 15 percent (%) slope with the
motor fully engaged.
Steep Hills and Hub
The Ninja Electric Bike uses
a high torque brushless hub motor with an internal planetary gear system which provides efficient performance for many types of riding conditions. Hub motors are
designed to provide years of trouble free use, however, if not taken care of, they can be damaged by overloading. Be sure to pedal with your Ninja Electric Bike when climbing
steep hills and ensure the wattage/power consumption is kept below 350 watts.
There are some important best
practices to follow to ensure long life and safe operation of your fat bike wheels and tires. Electric bikes travel at higher speeds on average compared to
regular pedal-only bikes, and they are also heavier in comparison; because of this, users must take care to
never abuse the Ninja Electric Bike wheelset.
- Avoid traveling over terrain
which can damage the tires or wheels.
- Ensure tire pressure is adequate
to avoid pinch flats and damage from low pressure.
- Check tire pressure regularly to ensure proper tire pressure (Ninja Electric Bikes
recommends 20-25 PSI for the Ninja Electric Bike) before riding.
Check disk brake pads
regularly and ensure they are properly adjusted and are not worn out. Always ensure both front and rear brakes are operating properly before riding, never ride with a single brake. Always apply both
brakes evenly when slowing.
Maximum Payload for
Ninja Electric Bike
The total maximum weight
limit of the Ninja (275 Lbs) includes the weight of the rider. The kickstand is not designed to be used for loading cargo. Total payload: 275
Other Passengers, and Gear
The use of certified and
approved child seating and equipment are required whenever carrying children. Follow the stated weight limits in the section above, do not overload the Ninja Electric Bike. The Ninja Electric
Bike should never be operated by persons under the age of 16 years old.
- Cleaning: Pressure washers or
hosing down of the Ninja Electric Bike voids the warranty. The Ninja Electric Bike should only be cleaned with a moist rag and non-corrosive biodegradable cleaners.
- Yearly maintenance checks: Your Ninja Electric Bike should be given a full tune-up by a
professional bicycle mechanic on a yearly basis.
- Brake pads: Electric bikes travel at higher speeds and have more momentum because of the
weight of the powered components, for this reason, brake pads normally wear down faster than a traditional non-powered bike. Users must check brake pads regularly and replace whenever worn.
- Tire Pressure: Ninja
Electric Bikes recommends 20-25 PSI for the Ninja Electric Bike.
