Range & Performance
Maximum range on a full charge can vary depending on many variables, such as: battery age, terrain, rider weight, temperature, riding style and speed. This chart represents approximate range based on normal road conditions with a rider weight of 200 lbs.
The battery pack is your e-cruiser's energy fuel tank:
AmpHours (Ah): This indicates how much energy your battery pack will hold. The higher the number, the larger your fuel tank is. For example, a 10 Ah battery pack will hold twice as much energy as a comparable 5 Ah battery pack. But that doesn't mean it will have twice the range.
Volts (v): Think of volts as how big your engine is, and the Controller Amps is the size of your carburetor. They don't affect the size of your energy fuel tank (battery), but greatly affect how fast you can use that energy.
Riding Style: How you ride your e-cruiser will have the most impact on its range. You can 'hot rod' for 15-20 miles or you can miserly dole out your energy at low speed and get 35-40 miles.
Tips for maximizing range: Battery packs are perhaps the single most expensive and mission critical component on your e-cruiser. Charge and store your battery pack (bike) at room temperature (65F-85F) if possible. It will optimize your e-cruiser's performance.
Charging your battery pack: Allow 6-8 hours for your battery pack to fully re-charge. When storing the bike, you can leave the charge cable connected. This will keep all the batteries fully maintained and ready for use. The battery pack on your Fat Woody has an internal BMS (Battery Management System) and can not be over-charged.
If you prefer, for peace of mind, you can leave it unplugged when not in use. The smaller on-board 12v battery will only hold a charge for 12-14 days, so you would need to freshen the charge of that battery for a few hours before riding. If the 12v battery is dead, the electric drive systems will not turn on.
Why does the 12v battery slowly drain? The 12v battery pack has an integral 'charged' LED on it which will slowly deplete the battery. It also has a switch to turn the battery off, but since the battery pack is located within the composite body, it is not viewable or accessible.
Conditions affecting your e-cruiser's range:
Ambient Temperature: Extreme cold and heat can affect the battery pack's energy capacity and overall e-bike performance.
Total number of charge cycles: As the battery pack ages, its ability to store energy decreases. Your battery pack is designed for 600-700 complete charge cycles.
Wind: Riding into a strong head-wind will use more energy.
Road Conditions: Sand and hilly terrain will definitely use more energy than level roads.
Load: The more the weight on the bike, the more energy is used. That includes the operator.
Repeated acceleration from a standing start: This is where the most energy is used. Gently feathering electric power to sustain forward motion is optimal and significantly increases your e-cruiser's range.
Speed: If you prefer to cruise everywhere at +20 mph, your range will be significantly less than if you cruise at 10 mph.
Poor Maintenance: Under inflated tires will definitely require more energy to turn, decreasing overall range.
