Here s how it works:
Very few actually HAVE to ride a bicycle. It s a CHOICE, a hobby.
For most of us it has the same practical importance as buying a new gaming computer, a new fly fishing rod, camera, gun, scope etc.
I d be SAD if I couldn t ride, but I wouldn t suffer. I d still be able to work, keep up with my payments, keep my home.
In the grand scale of things, no big deal. There are other ways to get around, exercise and have fun.
So any attempt at comparing how "sensible" one hobby spend is compared to another is basically pointless.
The "it s a pushbike" part doesn t make any sense.
What you re left with is:
1) do you have 1000 units to spend on a hobby while still paying for the unavoidable costs of life?
2) is the 1000 units a reasonable price for that item compared to market value?
3) are you reasonably certain you ll get "enough" enjoyment out of it?
If the answer to all above is "yes", I d be entirely content with spending 1000 units on the hobby item of my choice, whether it s a pushbike, a welder, a crate of rare beer or whatever.
