I sometimes miss my old trailstar and I would miss my old 95 fire mountain, but then I got a 97 off of Retrobike for pennies, SS’d it and it is every bit as fun as I remembered it being.
Oddly I’ve not missed the more expensive bikes I’ve owned…
TBH Yes OP you do need to MTFU, bikes are simply objects, you don’t get so attached to your kettle but that possesion arguably serves you about as regularly and faithfully as a decent bike…
Bikes can be used, broken, replaced, exchanged or given away if you like, the main thing is that they are of some use/benefit to you.
If you ride for the enjoyment of riding, and if a bike’s not being used for riding then it should be in line for the chop…
All IMO of course…
