I saw a guy (in america) charge his e-bike battery once at Starbucks. GPT estimates a full recharge to be around 30 cents.

Dude it's middle school math. Average pedal assist e-bike battery, estimate at 500 watt-hours. Electricity prices at my home are about 20 cents per kilowatt-hour.
(0.5 kwhr) * (20 cents/kwhr) = 10 cents. With an additional 10-15% due to charging system inefficiencies (lost to heat). 11 cents.
It can be good exercise to do an 8th grade level word problem every now and then.
The actual arithmetic is easy but most people don’t know about the batteries in e-bikes. They might not know about the electricity prices at the top of their heads either.
You could google those…but it seems easier to just use GPT if you’re going to google that stuff anyway.
Hah, probably comparable to running a desktop for an equivalent amount of time - most ebike chargers are 100 - 200 W, and the bikes usually have a battery between 0.5 - 1 kWh (which in my area would be 5 - 10 cents). Less disruptive though, assuming they detached the battery and left the bike outside.
