Pre-Ride Checklist
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 port.
Riding Off-Road and In Wet Weather
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 Terrain
In 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 Motors
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.
Wheels and Tires
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.
Using the Brakes
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 lbs
Carrying Children, 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.
