I have one bike that I ride, and while it's not a true beater, because I put a lot of money into it, it is beater-ish in the sense that I built it to be able to take lots of ****. So far, now that everything is dialed in, it needs almost no maintenance, and I use it for everything from urban riding on a daily basis to 10+ mile camping trips (after I attach a rack with a milk crate). It's a fixie conversion, and it looks good to boot. I just need to figure out how to make it winter-worthy.
