How long does it take to charge an e-bike, and what does it cost?
Typically 5–6 hours from empty with the stock 2–3 A charger. A full charge costs about $0.15 at the US average of 18.31¢/kWh, about 0.31¢ per mile.
How charge time works
Lithium-ion chargers push constant current until the pack is about 85% full, then hold the voltage while the current tapers off for roughly an hour. Time ≈ (85% of battery Wh) ÷ (full-charge volts × charger amps) + about 1 hour. A bigger charger shortens the first part, not the last.
Charge time and cost for every bike
Empty to full on the stock charger; cost at the US average residential price of 18.31¢/kWh with 85% charger efficiency.

Common questions
Does a fast charger hurt an e-bike battery?
A brand-approved fast charger (around 5 A) is designed for the pack. Charging is gentlest at 2–3 A; use fast charging when you need it, and never charge below freezing.
How much does it cost to charge an e-bike per month?
Riding 100 miles a month costs about $0.33–$0.37 in electricity at the US average price. Even at California prices it's a few dollars.
