Conversion TimeStarted on the 5th of May 2012 and worked
on project for
month. Spent most of my time learning how
to build the bike
from evalbum and other sources. Finding
the right company to
buy the parts from was time consuming.
Went on holidays and dropped project.
Started work this March on project again
as the weather is warmer.
It's been 2 years and I stalled
the project because of
battery costs.2019 Put in battery rack and
worked on some wiring of the bike.
Hope to complete this one day.

Additional FeaturesNote: I may need to strengthen the bike as the engine was
structural support to the frame and without the engine it may
be weakened.
Put a battery rack holder on where engine was fitted. Put two
angle irons across from front engine holder to back chassis
and bolted onto frame to replace engine support and make it
safe. Stopped the build a while back as batteries
cost too much. In Europe at the moment and hope to finish
build next year. "This has been a long project and one of the
few I have not completed.

Started on May 5th and had engine removed in 4hrs.
Fixed brakes and speedo. Headlamp 12V (garage sale)
I have talked to and they are very
Bought most parts and mounted the motor.
Got welding wire, electric lugs and chain for 48V at
Princess Auto (Canada)
March: Painted gas tank yellow and guards yellow so
motorcycle is spotted easily from the
side. Mounted ignition key in gas cap.
Painted and mounted speedo.
Got old bed frames for angle iron for free and mounted the
controller. Used the angle iron for battery frame so all I
need is the right batteries. This has been a slow project
with high costs but it's worth it. Installed battery rack

thunderstruck (new and used parts)

*Note: this is a great site for research on products that
others used to build e.v.'s
One can research mileage, speed and products used and come to
your own conclusion
on what is needed for your build.
"good luck"
