OP asks for suggestions on a bike to ride a 3 flat miles in an area with extremely high crime, and says he is prepared for it to get stolen.
Suggestions: giant, jamis, 29er, LBS, trek, cannondale, disc brakes required. No hybrids cuz they aren't hardcore has to be full out MTB or dedicated road bike don't look at any other options.
If you don't find that hilarious then I don't know what to tell you.
He/she needs a cheapo walmart/sporting goods $100 bike. Not a worn out LBS craigslist $300 bike that's going to get stolen anyway.
The m3 analogy is a sort of ubiquitous term for this type of elitist attitude..
3 kids trying to get to waitress job = e46 m3 and do maintenance yourself
Commuter in snow = e46 m3 with 2nd set of tires
Gravel road = e46 m3 with strut brace
Camping car = e46 m3 with roof rack
