Electricity Cost calculation:


Given information:
- Power cost: 7.4 cents/kWh
- Battery: 48V - 12AH
- Range: 50 km per daily charge


Step 1: Calculate the battery capacity in kWh
Battery capacity = Voltage * Ampere-hours
48V * 12AH = 576 W = 0.576 kWh


Step 2: Calculate the cost per full charge
Cost per charge = Battery capacity * Power cost
0.576 kWh * $0.074/kWh = $0.042624


Step 3: Calculate daily electricity cost
Daily electricity cost = Cost per charge
$0.042624 per day


Step 4: Calculate annual electricity cost
Annual electricity cost = Daily cost * 365 days
$0.042624 * 365 = $15.55776


Step 5: Calculate 10-year electricity cost
10-year electricity cost = Annual cost * 10
$15.55776 * 10 = $155.5776


We can update our total cost over 10 years:


Purchase price: $7,777
Maintenance (10 years): $2,060
Electricity (10 years): $155.5776
Total: $9,992.5776


New cost per kilometer: $9,992.5776 / 182,500 km = $0.0547 per km


This calculation confirms that the e-bike is about 11 times more cost-effective than the car ($0.59 / $0.0547 ≈ 10.8)
