Vehicle2017 Softail Chopper
Building a tribute to this American Choppers S06E15 Siemens Smart Chopper from the ground up using a ProTube frame and making a few improvements: 168 volt Li-Poly batteries not 72 volt lead-acid; 100 HP Advanced DC 9" 144 volt motor; an on-board 6.6kw charger; and finally, lots more chrome.
MotorAdvanced DC FB1-4001 Series Wound DC
Voltage: 144 DC
Power: 100 horses, 75kw
Weight: 143 pounds
Diameter: 9.1 inches
Length: 15.62 inches
DrivetrainDirect drive via a single 530 chain with sprockets: 26 front, 48 rear producing a final 1.86:1 ratio. At 3,400 rpm the bike should go about 167 miles per hour.
ControllerZeva MC1000C
Slightly over volting with 168 volts and
grossly over amping 1,000 amps for short
durations... like during a quarter mile run
should produce 220 hp on demand.
Batteries200 Panasonic Li-Poly, 4.20 Volt, Lithium-Polymer
The 200 cells are arranged in modules. 5 parallel groups of 5 modules in series. Each module has 8 Li-Poly cells at 4.2 volts totaling 33.6 volts and 1.1 Kwh of power totaling 27.2kwh.
System Voltage168 Volts
ChargerElcon 168 volts - 6,600 watts
Elcon UHF Charger 168 volts @ 6.6kW waterproof CAN bus controlled.
DC/DC Converter PC Power supply
Modified an 800 watt PC Power Supply to take
168 volts DC input from the battery pack and
give 12 volts output. Just bypass the full
wave bridge rectifier and you're done.
InstrumentationKoso Digital Speedometer / Dashboard
Top Speed167 MPH (268 KPH)
Top speed can only be approximated since this is a work in progress. The motor max RPM is 7,000 but max torque is at 3,400 so sprocket ratio of 1.86:1 has peak power output arrive at 167 mph.
AccelerationOMG, should run like a Tesla Model S.
Range300 Miles (482 Kilometers)
SWAG: 300 miles. This is only a guess since it is a work in progress. We're using Nissan Leaf sized motor and 27.2 kWh of power, but with 600 pounds instead of 3,400. That's 5 times less weight, and less than half of the frontal area. A Leaf gets 100 miles on a charge. That is around 270 watts per mile. A Tesla Model S routinely uses 345 watts per mile at 5,000 pounds and my lead foot. If we can use around 90 watts per mile that will let us get almost 300 miles per charge. That compares to the Model S Tesla with 85 kWh with a 300 mile range.
Watt Hours/Mile90 Wh/Mile
Only theoretical.
Seating Capacity2 adults
Curb Weight620 Pounds (281 Kilograms)
Weight of bike is unknown and approximations are based on component weight. Units of weight are pounds: Motor 143, batteries 170 chassis 150, fork 65, front wheel 19, rear wheel 42, controller charger cables and fiberglass faring are to be determined.
Tires19" x 3" Front Avon
18" x 12" Rear Avon Venom
Conversion CostNo comment, my wife might read this.
