I would say yes, judging by all the Hispanic fellows I see-out in all weather-on everything from department store mountain bikes to 1970s 10-speeds with safety grips. I alternated for years between my Raleigh Super Course MKII and Kabuki Submariner. Installed padded handlebar coverings, Brooks B-17 saddles,Union generator sets, Blackburn racks, fenders.
Then in 1999 I switched to 3-speeds for something different, a little nostalgia, a "retro" feel.
Brooks saddles, generator lights,Pletscher racks, flasherson the racks. The bicycle is merely a conveyance. Proper lights, a comfortable saddle, a saddlebag with tools, patch kit, and pump.
I tried my mountain bike a few times, didn't find it that comfortable for around town use, but that's just my opinion.
