Conversion TimeWhat is time anyway?
Conversion CostStopped counting after $10000CA, most of the
cost was for lithium batteries, motor, motor
controller and chargers.
Additional FeaturesLED headlight, tail lights and signal lights. AC cord on
retractor stolen from a vacuum cleaner. Custom control breakout box
for vehicle control and future upgrades. Removed one front
rotor/caliper to reduce weight. Stash box under the seat where the
old battery compartment was.
Advice: Educate yourself about batteries, especially lithium. Had
taken the time to study up, I would have saved a lot of cash.

Thanks to EV Album for ideas gleaned off other conversions. Thanks
my father for all the welding work, beer, conceptual ideas and
allowing me to make a mess of his garage. Thanks to Ian for
the rear sprocket; looks stock.

7 September 2020
Over the years I have sufficiently abused the cells to the point
of reducing max range to about 25km. Plans are underway to
replacing the entire pack to 60Ahr.

21 August 2022
New battery pack is in and I'm very pleased with the results.
Installed an LED headlamp to replace the HID lamp that started
giving me problems.

6 August 2023
New paint job to match the battery cell colour.
