Vehicle1978 Honda CB750 F2
Built by my fiance Lori and I with the help of a local machine shop, Ironman Fabrication's time and space. A CraigsList.org donor invited me to
drag this motorcycle out of his yard. It took three of us to get
it onto a truck sideways and we left a streak where the rear
tire had dug into his grass. The thing was rusted in a locked up position.
MotorD&D Motor Systems, Inc. Separately Excited DC
13HP regen and reverse. Capable of ~300A.

I'd liken it to a 250cc bike's power, though when and how they make power are different. If I had gears like a Honda rebel it'd be no contest.
DrivetrainOne speed, 420 chain. 12/60 gears.
ControllerAlltrax 4884
300A controller.
Batteries16 China HiPower HiPower LifePo4, 3.20 Volt, Lead-Acid, AGM
The whole pack is 100AH at 48V. Do far i've gone 20 mile son it, so no clue on real range, though I suspect it's over 60 mi in mixed driving. Update soon.
System Voltage48 Volts
Chargerunknown BC0 or BCO 16 cell balancer charger for Li
58.6v, 8Amp.

Slick Little fellow works well. after first rides, the batteries are within 30mv of each other.
Heaterwhatever I'm wearing.
DC/DC Converter nope. isolated circuit. Solar powered 5v USB circu
LI rechargeable battery powered, and the back tail-light is a
"spooklight" that has accelerometer controlled brake lights
and turn signals that are wirelessly controlled by a remote on
the handle bars.
Instrumentationfactory Honda Speedo.

CellLog monitors on all cells.

48v cart gauge for overall "pack at a glance" is mounted to the tank.
Top Speed55 MPH (88 KPH)
The top speed is around 55 mph so far. Only the Interstate and highways around NWA are over 40mph, so I have enough go-power to get a speeding ticket just about everywhere in my range.
Accelerationconfidence inspiring, and really quite good.
0-30 is faster than most cars are at the stoplights. 30-50 is
smooth but slower. I'm due to experiment with the gearing
some.

It'll do a burnout.
Range50 Miles (80 Kilometers)
Will update with solid scientific information soon.
Watt Hours/Miletbd. instrumentation is lacking. Only have a battery meter.
EV Miles
Start:33,055 Miles (53,185 Kilometers)
Current:33 Miles (53 Kilometers)
Total:-33,022 Miles (-53,132 Kilometers)
Seating Capacity2ish. seats 2 but no rear sets for passenger feet. easy to add
them back.
Curb Weight400 Pounds (181 Kilograms)
this is an absolute guess, but it is lighter and better handling
than before.
Tiressome on sale rubber from oldbikebarn.com front tire came with the e-bayed rim.
Conversion TimeI've spent about 3 years doing this.I've even moved houses in
between.

This is the bike's "Revision 2.0" Anything I Know I did wrong the first time I have corrected but I'm sure there is more to learn.
Conversion Cost3-4000$ from scratch. almost all of that is EV pats. TH lead acid version was half that.
Additional FeaturesThe bike has had the rear brake deleted and shaved down the old brackets so now the regen motor does all rear braking.
extra special thanks to my wife!
