I am quite ok with motorcycle, tax, and mot etc. on the electric Harley.
OCC did an electric harley.
I would probably use somethin around 20-30-50 kW depending on
availability, and about 40-80 kg of batteries.
At 260 W/kg, == 20 kWh max.
Batteries would come from a wrecked electric car, probably.
I think for about 1000€ I could get enough batteries from some form of
newish electric car, from a wrecker.
Likely, about 4-5 kW load, would give decent speed, and a 3-4 hour range.
At say 80 km/hr, thats == 240-300 km.
At 300 km, thats 20/300 == 0.06W/km or 60 watts/km. vs a tesla S at
160W/km, with maybe 4 times the surface area.
All numbers from the best scientific tlar method.
I suspect 20 kW would be plenty.
A HD sporster is NOT simething I go driving fast in.
(My ex Subary STI WRX, yeah.)
Since it´s an opportunistic buy, I would likely just run the batts
through some electronic converter, if they did not have suitable
voltage, etc.
Electronics are dead cheap, and the 3-7% efficiency penalty is
immaterial, with a bigger (cery cheap) battery.
Charging for electrics is 0.03-0.04€/ kWh, essentially free.
And free at shopping malls.
A 20 kW charger is only 500€ (for a tesla).
I could add one into the bike, and just use the carrefour supermarkets,
from the electric-car plugs.
While 30 min shoppping and a "canja", battery gets full.
