Battery Range & Care
Your battery can be the most expensive component on your electric bike, so taking good care of it can make all the difference.
Before you ride your E-bike for the first time, it is recommended that you charge the battery for 8 hours before your first ride. An initial charge will help condition your battery and allow for optimum performance throughout its life. Please note that your charger's status light may turn from red(charging) to green (fully charged) before the conclusion of the 8 hours. Allow the first charge to continue until the full 8 hours are complete.
Range and Performance
Maximum range on a full charge can vary depending on many variables, such as: battery age, terrain, rider weight, temperature, riding style, amount of rider pedaling and speed. At 20 mph on normal road conditions, with fully inflated tires, your range should be between 15 and 30 miles. Battery range below or above this level can be affected by conditions. For more specifics, most bike model pages includes a link to a range calculator. Bosch has a range calculator that is typical of most mid-drive systems.
Conditions that affect your battery’s range:
• Ambient Temperature: Extreme cold and heat can affect the batteries capacity.
• Total Number of Charge Cycles: As the battery ages, total capacity can decrease.
• Wind: Riding into a strong headwind can decrease range.
• Road Conditions: Excessively rough or hilly terrain requires the consumption of more power.
• Load: Carrying extra weight on the bike or in a backpack will use more energy.
• Operator Weight.
• Repeated Acceleration from a Standing Start.
• Proper Gear Usage: Taking full advantage of the available gears will significantly increase range.
• Poor Maintenance: Under inflated tires, misadjusted brakes, a dry or dirty chain, can decrease range.
Tips for Maximizing Range:
• Charge the Battery at room Temperature (60-85°F)
• Lithium Batteries have no chemical memory, and it is not necessary to discharge the battery completely for best performance. Charging a partially full battery will have no negative effects.
• Use the bicycles gears as much as possible when encountering terrain.
• Maintain proper tire pressures and lube the chain regularly
• Operating temperatures between 40°F and 85°F will significantly increase range
• Get your bike a regular (every 6 months) tune up.
If used in accordance with these guidelines, your battery has an expected life span of up to 1000 charge cycles, or as few as 400 charge cycles for batteries that have been "stressed". For Extended Storage, always fully charge the battery before leaving the bicycle unused for extended lengths of time. Recharge the battery every 90-days during storage for optimum battery performance.
Removing The Battery
Unlock the battery using the battery key by turning the key counterclockwise, in the top keyhole of the battery bracket. Next, slide the battery forward in the mount about one inch. Finally, lift the battery up and out of the dock. There is no need to disconnect any wires to remove the battery. Reinstallation is the reverse of removal. Be sure to lock the battery once it is replaced by turning the key clockwise to prevent the battery from coming out of the dock when you go over a bump.
Charging The Battery
Connect the AC plug from the charger to a wall socket. Avoid using extension cords because the high amperage could heat up the wires too much. Lift up the charging port dust cover located on the side of the Battery. Insert the plug from the battery charger into the round port on the side of the battery. •The light on the charger should now indicate a steady red light while charging. If the light remains green, the battery may already be completely charged. A full charge should take approximately 4–6 hours to complete depending on the state of discharge, at which point the charger should indicate a steady green light. When the charge is complete, first, unplug the charger from the battery. The battery should be ready for use. On some bikes, you may be able to charge the battery while it is still mounted in the frame of the bike. If doing so outside, ensure that the battery, charger, and power cables are protected from the elements. Failure to do so may result in electrocution, injury, or death.
