I have 15 bikes, the three I ride the most have 6,000 5,300 and 7500.showing now.

The bike with 7500 on it I have about $800 into. If it was exactly $750 in it then it would be a penny a mile but it's down to less than a penny ( 0.9375 of a cent.)
I don't feel like I spend to much on bikes anymore.

The 6000 miles bike was $6,000 A dollar a mile
The 5,300 bike was about $200 so far. 0.37735849056603773584905660377358 of a penny per mile.

COOL !! I never did this before.

The 7,500 mile bike 500 miles ago in the spring
