Building a tribute to this American
Choppers S06E15 Siemens Smart Chopper
the ground up using a ProTube frame
making a few improvements: 168 volt
Poly batteries not 72 volt lead-acid;
HP Advanced DC 9" 144 volt motor; an
on-board 3.3kw charger; and finally,
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
sprockets: 26 front, 48 rear
producing a
final 1.86:1 ratio. At 3,400 rpm the
should go about 167 miles per hour.
ControllerZeva MC1000C
Slightly over volting with 168 volts
grossly over amping 1,000 amps for
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
Each module has 8 Li-Poly cells at
4.2 volts
totaling 33.6 volts and 1.1 Kwh of
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
batteries, 27.2 kWh, but with 600
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
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
300 miles per charge. That compares
to the
Model S Tesla with 85 kWh with a 300
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.
