The GSA usage rate is $0.585/mile. That is $9.945/day in car usage from a 8.5 mile commute to the office. I understand you can drive for less than this rate, but it would be hard to reach $0.35/mile and doing so would sacrifice dependability of the motor vehicle. My e-bike is significantly cheaper to maintain than my car. It uses something like .7KWH for a full charge which handles over 30 miles. Thats less than 10 cents for a full charge at my rate. Other consumable goods like tires, chains, tubes, break pads are all similarly 10x-100x cheaper than their car counterpart. The only expensive wear item is the battery pack, which admittedly cost $550. I'd estimate my personal usage of the device to be around $0.05/mile. It's cheaper to own both and maintain both if you are going to use both. Using simple linear math, the ebike will save you over $2000 in ongoing costs (initial price) within 3850 miles or 235 commutes. A pretty good ROI.
