My expectations of a good commuter bike shop/store since my cycling includes riding for transportation for past 2 decades:

*decent selection of strong bike racks to accommodate a variety of bike geometries and carrying heavy weight (meaning over 30-40 lbs.), including folding bikes, cargo bikes
*wide selection of bike panniers, of different sizes and colours, configurations
*decent selection of bike baskets (though I don't use them/have one)
*inventory should include wide variety of hybrids, cargo bikes, folding bikes
*wide range of gloves for all season cyclists and cycling shoes that don't require clipless pedals
*local bike maps, local books on cycling routes, etc.
*wide variety of helmets
*wide selection of cycling glasses including clear glasses...at reasonable prices. Not $200.00 per pair. I'm sorry I can't spend that kind of dough for 1 pr.

Vancouver has about 2 shops that fit that criteria. Toronto has at least 1-2. Calgary...gettin' there but there's not 1 store I can pinpoint exactly for all the stuff I need.

By the way, I don't consider a beach bicycle, a commuting bicycle even though others would. It looks like an uncomfortable ride beyond 15-20 km. around town, especially for hills.
