Guys like motorcycles to varying degrees: the fully committed actually buy choppers, while the casually interested buy the notion that American Chopper: Junior vs. Senior is must-see TV. For a local shop with biker goods to cover the entire spectrum, check out Classified Moto.
Specializing in "affordable alt-moto customs and random creative expressions", Moto recycles old motorbikes into both brand-new retro cruisers and bike-part art (TM!), all in a tiny Richmond workshop.
If you're all in, they'll work with you to design your custom bike a la recent creations like a converted Honda Twinstar with a basket made from an old water ski & a taillight from a steel fishing rod, an '82 Yamaha XS650 w/ Woodcraft clamshell clip-ons, and another '82 Yamaha they say is like riding "G.I. Joe’s personal assault bike", trimmed down to "fighting weight" and fitted with top-mounted "hooligan bars" (English soccer fans do need to get a grip).
Should you lack the lugnuts to actually ride, they've Frankenstein'd spare parts from '70s & '80s Japanese motorcycles into home furnishings like a wooden high table with transmission gears for feet, a brake rotor lamp, and a sconce crafted from a spring and shock absorber, which'll be useful for calming your girlfriend after she learns you also bought one of the motorcycles.
And for the truly lukewarm bike enthusiast, they've got tees (with "CM" spelled out by bike chains) and moto-artsy, limited-edition screen prints, both of which are infinitely more affordable than the other stuff, just in case you're so broke that splurging on a motorcycle would be grounds for having you committed.
