|Vehicle||1978 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
|Motor||D&D Motor Systems, Inc. Separately Excited DC|
13HP regen and reverse. Capable of ~300A. Controller set to
limit it to 100A
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.
|Drivetrain||One speed, 420 chain. 12/60 gears. |
300A controller. Set to 100A with a soft acceleration curve.
|Batteries||16 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 Voltage||48 Volts|
|Charger||unknown BC0 or BCO 16 cell balancer charger for Li|
Slick Little fellow works well. after first rides, the batteries are
within 30mv of each other.
|Heater||whatever 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.
|Instrumentation||factory Honda Speedo.|
CellLog monitors on all cells.
48v cart gauge for overall "pack at a glance" is mounted to the
|Top Speed||55 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.
|Acceleration||confidence 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
|Range||50 Miles (80 Kilometers)|
as tested in mixed use. had some headroom left.
|Watt Hours/Mile||tbd. instrumentation is lacking. Only have a battery meter.|
|Seating Capacity||2ish. seats 2 but no rear sets for passenger feet. easy to add |
|Curb Weight||420 Pounds (190 Kilograms)|
according to the metal scrap yard, it is lighter and more lithe
handling than before.
|Tires||some on sale rubber from oldbikebarn.com|
|Conversion Time||I've spent about 3 years doing this.I've even moved houses in |
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 Cost||3-4000$ from scratch. almost all of that is EV pats. TH lead acid |
version was half that.
|Additional Features||The bike has had the rear brake deleted and shaved down the old brackets so now the regen |
motor does all rear braking.
