@sexy_peach late 80s/early 90s ATB bikes are absolutely PERFECT for daily use. Great gear range, great geometry.
The only problem I have these days is tire selection dwindling for 26 inch (america) tires. Just not as many companies are producing in that size anymore.
@TubularTittyFrog I think proper fit would solve both those problems. Bike coops are great for that. Modern road/hybrid bikes tend to have aggressive gearing that tries to emulate race bikes, and I think that makes things much harder for people trying to use their bikes practically.
