4,000 hard miles on my Sparta and counting, just a set of brake pads, and the battery is still doing or saying about 40 miles per charge.
The saddle is knackered though, too many days left out in the wet. Have a Brooks arriving next week, 70 quid! But should last forever.
It was £2,500 to buy but so far it's cost about 15 quid for the brakes, some pounds on good oil and cloths, a train ticket to London to sort out a defective connector.
I had the fear about reliability but it's nothing to worry about, £1500 is probably entry level to get a decent one. The marathon plus tyres were an option for mine, £100 or something including fitting, ouch, but never had a I puncture and they still have plenty of tread left, amazing!
I look after it, clean it once in a while, pump the tyres up, oil it regularly, but she's been epic.
It's showing the miles, scrapes and wotnot, but to ride it's as good as ever.
Not bad for 4,000 miles.
Bike miles are hard miles, when I had motorbikes you were lucky to get 10K out of a 2 stroke before the engine was playing up.
