Keyed Power Switch: Enables e-Bike Electrical Systems
A keyed switch allows users to enable/disable all e-cruiser electrical systems (electric drive, horn & lighting). It's primary function is to prevent any systems from draining your batteries (e.g. lights left on), while it also serves to provide a simple form of security, ensuring only the key holder can activate the bike's electrical systems.
- Keyed Switch: Insert and turn the key to the ON position (clockwise). This enables the e-cruiser electrical systems.
- The key can be removed in both 'off & on' positions if desired.
- Turn the key off when not in use. It will drain the battery.
- The key switch is not an anti-theft device. It will not prevent anyone from riding the e-cruiser manually (e.g. pedaling, pushing, etc.).
- Turn the key to the OFF position (counter-clockwise) when the bike is not in use. If left in the ON position, it will drain the 12v accessory battery in 48-72 hours. The electric drive systems will not operate if the 12v battery is dead.
3-Position 'Power Mode' Switch
Fat Woody provides riders with a choice of three (3) power modes/settings. Owners can program speed & power limits for each of these modes. This allows the bike to have a State compliant 'street legal' mode of operation for operation on public roadways, while also providing an 'unlimited power' mode for off-road, steep hills, and sand.
- Setting I: Low Power Setting - 'Street Legal' Mode (e.g. 1000 watts @ 20 mph max speed)
- Setting II: Medium Power Setting - 'Off-Road' Mode (e.g. 1500 watts @ 25 mph max speed)
- Setting III: High Power Setting - 'Unlimited' Mode (e.g. 2500 watts @ 30 mph)
These are just examples of how the e-bike management system can be setup for your specific needs (State requirements)
Dashboard Pushbutton Control Switches
There are four (4) pushbutton switches that provide control of various e-cruiser systems.
- Main Power Button: Press to activate e-bike electric drive system (LCD display) and 12v accessory systems (lights, horn).
- Lighting Button: Press to activate headlamp & tail lamp. Pushbutton switch lighting will also illuminate.
- Horn Button: Activates the Fat Woody 'look at me' audible horn device.
- Cruise Control Button: Press the thumb throttle to get to the speed you want to cruise at. Once at a steady speed, press the cruiser control momentary pushbutton and the e-bike will maintain that speed. To disengage cruise control, operate either brake lever or press the thumb throttle again.
Safety Note: Cruise control can pose a potentially dangerous runaway situation. Inexperienced or unfamiliar operators can become confused as to how to disengage cruise control properly, so exercise extreme caution using this feature.
Cycle Analyst e-Bike Computer
What it is...
The Cycle Analyst is the first digital dashboard and battery monitor originally designed around the specific needs of electric bicycle. Its flexible setup configurations, wide feature range, and affordable price have led it to widespread appeal in a range of other EV (electric vehicle) applications. From the dashboard of MIT's solar car, to record breaking electric motorbikes, to small trains, powered wheelchairs, and even sailboats and airplanes, the Cycle Analyst has become the e-meter of choice for keeping track of the vehicles battery usage and performance characteristics.
What it does...
Once connected to the vehicle's power bus, the Cycle Analyst calculates and shows the following information:
- Volts, Watts, Amps: The instantaneous electric power being drawn from the battery.
- Amp-Hours, Watt Hours: The net energy that has been pulled from the pack since the meter was reset. The accumulated amp-hours let you know the remaining energy in the battery pack with far greater accuracy than a voltage or LED indicator.
- Speed, Distance, Time: All of the basic features of a bicycle computer, including the average and maximum trip speeds, plus a total distance odometer.
- Total Battery Cycles and Amp-Hours: Retains life cycle information on the vehicle's battery pack, such as how many charge and discharge cycles the pack has experienced and the total amp-hours that were delivered over its entire life.
Furthermore, the Cycle Analyst has the ability to over-ride the user's throttle and regulate the power delivered to the motor, turning an otherwise dumb e-bike into an intelligent device with a user programmable speed limit, current limit, and low voltage cutout.
- Speed Limit: This has the utility of providing legal compliance to the speed cap imposed on e-bikes in most jurisdictions. When used with a full throttle, it serves as a cruise control on the electric bicycle. It can also be beneficial to riders who want to increase their torque and power by using a higher voltage battery, without simultaneously increasing their top-end speed.
- Current Limit: An adjustable amps limit is useful to prevent damage to the batteries from excessive current draw, to increase the range that you'll get on a charge, and to protect the motor controller and motor in setups that draw too many amps.
- Voltage Cutout: A low voltage cutout is used to protect a battery pack from being discharged too deeply, which can cause cell reversals in NIMH/NiCad packs, permanent cell damage in Lithium packs, and sulfation in Lead Acid batteries. The programmable low voltage rollback allows you to set an appropriate low voltage point tailored to your pack.
Builder's Note: The power e-bike systems operate within is substantial and it can easily fry your rear hub motor, battery pack and associated controller systems without warning.
Example: Going uphill or plowing through sand generates a tremendous amount of heat within your e-bike motor. E-bike users for years have had to use what we could now call dumb e-bikes. Just a simple battery level indicator and that's it. You don't know exactly when you were approaching the limits of your e-bike electrical system. This resulted in a lot of e-bike system melt-downs. $$$
Having the technology capability to sense heat in the motor and automatically rollback throttle and power, protecting your electric drive system and associated components, is essential. The Cycle Analyst 'intelligent' e-bike management system on your Fat Woody e-cruiser has been configured to provide optimum performance and protection of your e-cruiser investment.
Additional features include:
- Backlit LCD: The display readout is well illuminated for night riding.
- Water Resistant: The circuitry is fully enclosed in a sealed box enabling it to withstand exposure to wet and rainy conditions.
- Save on Power Down: Trip data such as amp-hours and distance are saved when the meter is shut off, and are restored when power is re-applied.
