The top three most efficient modes of human-powered transportation are (in no particular order): Flintstone cars, bicycles, and a palanquin carried by the various monarchs you've conquered and overthrown. Make sure the most feasible of these is accessorized and in perfect working order with today's Groupon: for $20, you get $40 toward cycling equipment and repairs at Outdoor Element Sports.

Outdoor Element Sports helps spin the spokes of life by stocking its shelves with all manner of two-wheeler accouterments. Outfit yourself or a peddling pal with a bicycle helmet, which shields noggins under a cushiony layer of foam padding and helmet hair ($30–$140). Cycling-themed jerseys proudly display transportation loyalties ($40–$80), and a pair of bike and skate shorts sheathes thighs in clandestine, chafe-less fashion ($50–$80).

For velocipede-less visitors, Outdoor Element Sports outfits both purposeful peddlers and casual cruisers with numerous mountain bicycles ($300+). Tandem up tots with children's mountain bikes, which encourage exercise and allow kids to apply for fuel-efficiency tax credits on allowances ($130–$500). Four-wheeling Tony Hawkers can choose from the store's longboards ($180–$280) or pro decks ($56–$64) and necessary trucks ($40–$70) and wheels ($20–$50). The cycling craftsmen at Outdoor Element also deftly repair weakened wheelers, often fixing small repairs on the spot ($35 average).
