I've been living in a seriously hilly area for the last 6 months doing daily school runs so I switched from my fixed to my 1x10 MTB. Prior to this I rode almost exclusively fixed for many years. Getting back on geared/freewheel I've rediscovered the joy of downhills and realised that's probably the worst part about riding fixed for me.
After months riding geared I started to wonder if I was done with fixed, I'm 45 and gears were feeling like a luxury. I eventually dared to take the fixed out again on the hills and it felt great, so much fun, descents still sucked a bit though. So, I still love fixed and will probably keep doing it until that changes (or my knees pack in). I do plan to treat myself to a nice geared bike at some point though.
