back in the old days pre wife & kids, I once worked out the true cost of a ride and found my bikes were costing me about £1 a mile in bits
This.
Although My pitch probably costs vastly more as it was bought new, suffers terminal upgradeitis and proabably 25% it’s miles so far have been on uplifts!
My Swift (and preceeding singlespeeds) on the other hand probably costs almost nothing, I’ve only bought them 2 new tyres in several years, and breakages are replace from the spares bin. They were all s/h so the cost is negligable as if/when they get sold you probably only lose 10-20% by buying complete bikes, using them, then selling on the big ticket items and binning the drivetrain/consumables.
I rarely count petrol as I have to drive a lot anyway so most rides start from wherever I’m calling home that weekend, once I settle back down in Wokingham it’ll add up more.
