Good morning,
After adding in the cost of the end of the year service, I am at £660 on bike bits essential to the commute in 2022, this covers about 7,400 miles, or 9 per mile, excluding fuel costs and any allocation of the purchase price.
With fuel, say £3/day for 36 miles, yes some days it is two packs of fig rolls others it's a Big Mac meal, it is up to 17p per mile and £800 depreciation brings it up to 27p per mile.
I am pretty sure that I have missed out at least one purchase of tyres as well!!
Also chain and cassette wear is not fully reflected as I started the commute on an 8 speed which was nicked so no new chain/cassette was needed, the 10speed also had a new chain/cassette at the start of its use as a commute bike and I stretched life a bit,
There is only £20 worth of labour in the above, I needed the BB fixed in a hurry and it is Shimano into BB30 via an adaptor.
Apart from the wheels, which will quite likely last 3-5 years the rest is consumable/similar purchases will be needed next year, it turned out to be really hard to get the right sized hub spares.
In particular notice that I haven't included a cost for lights as they are needed anyway, but charging twice a day is going to be anything from a quarter to all of the recharge cycles for the batteries.
Bye
Ian
