This is an approximate measurement of your cost per charge for your bike. We will be doing some real-life tests to gather more info

**You will need:**

-Battery voltage ( 48 or 52V for now)

-Battery Amps/Hour size

-Local cost per kWh ( kilowatt /hour)An you can use both peak time and non-peak time costs

**To get the estimated cost per charge**

-Multiply your Battery Voltage * Amps/Hour to get the Watt/hour capacity

Example 52V/13Ah =676 Wh

-Then you divide by 1000 to get kiloWatt/Hours

Example 676Wh/1000 = 0.676 kWh

-Now multiply by your average kWh rate

An example in San Diego the average house kWh cost is 16.3 cents per kWh

we get 16.3 * 0.676 kWh = 11 Cents

Fully charging your 52V 13Ah battery in San Diego costs you 11 cents

**To estimate the cost per mile**

This is a bit more average as your range will vary. So we invite you to use the lowest range per charge you get to calculate the highest price. You will divide your Watt-hour capacity for the average amount of miles per charge to get the Wh per mile you ride.

Watt hour /average range = 676 Wh / 34 miles =19.88 Wh/mi

-Now you divide the total charge cost of your pack per the Wh/mi

11 cents /19.88 Wh/mi =0.55 cents per mile which is basically 1 cent every 2 miles
