2000 mile update

The bike and batteries are still holding up well beside the mid to high 90 temps. Only problem thus far is the rack and a puncture. I decided to go ahead and do a cost breakdown between the Woo and The e-bike. The batteries I can get for free but when I need to replace them, If I had to buy them, they would be around $102. As of today the replacement rate would be 5.2 cents/mile. I have a feeling I can get another 500+ miles out of them.

Woo

For the 14 months I had the Woo it came out to .27 cents/ mile including insurance. The only major cost was replacing the tires.

Mileage 11753
Gasoline 285 gallons- Avg cost 2.52/gallon
Lifetime FE- 41.24

E-bike-11.7 cents/mile
I really don't know how to do this so will break it down to getting the bike set up and then repair cost. Also operational cost since set up. I'll put the numbers out there so people can figure it anyway they want. The kit was $450 and the bike was free.

Bike setup- $155.04
Tires, lights, blinkies, chain, Panniers, and tubes.

Repair cost- $75.76
Bike rack, Tire, Tube, and gloves

I've put just 1965 miles on the bike. I've used 12.21 kwh of energy. That works out to 6.2 watts/mile. Or electric cost here is 13.1 c/kwh. Excluding electric but Including bike setup and repair cost it's comes out to 11.7 cents/ mile. For just repair it works out to 3.9 cents/mile.

The electric energy cost would be tough to calculate because a little more then a 1/3 is from work where the manager lets me charge for free. Then there are the added costs of more laundry, food, and showers. Then again some of this is at work. On the plus side I've not been sick in over 10 years. I'm sure I've messed up some of the calculation but these are all the expenses that I have incurred since getting the bike.
