On a Sunday in October we are in search of a bike shop. Between the two of us we have a bald tire and aging brakes. In 2014 we’ve increased our miles ridden, part of the transition to a single car and a Mission apartment. In exchange, bicycles that have neither needed nor recieved maintenance in years are due and deserving. Over lunch we search out a place, now an act of skimming crowd-sourced recommendations that becomes more familiar with every move. We rely on those we have never met so regularly, bus drivers and engineers, architects and grid operators, that asking for recommendations anonymously is an easy habit. It’s an exchange made more personal by profiles and star ratings for restaurants and shops, if not more important. And with each recommendation tested we become more comfortable in this, our third San Francisco neighborhood. It is a comfort built on learning, slowly, where to go for what. For bicycles this is our first try. Our last cycle shop was in the Sunset, and evolved during our time in the neighborhood, Roaring Mouse transforming into Everybody Bikes as the former moved to the Marina.

In the Richmond we did not have a local favorite, preferring the 38 and a walk to a chill ride home through Golden Gate Park most nights.

In Shanghai we had many mechanics, all over the city, wherever they were needed.

On Nanyang Lu behind Plaza 66 one evening, having gotten a flat on a broken bottle. Somewhere in the old town one night after a volleyball game when the starter on my electric scooter failed. Mostly, though, on Yongjia Lu at Yueyang Lu, a block from our last apartment. A tiny shop, really the front of a house, filled with equipment packed densly in each evening and pulled out on to the sidewalk during business hours. The man who ran it also made keys.

On these earlier searches we mostly did not have Yelp, did not rely on unknown people, save for the mechanics themselves, or other cyclists met on the street. Instead we used the bicycles themselves to explore and discover.

Like all such searches, in the Mission we are seeking both convenience and quality, focusing on a small area and hoping that our neighborhood can support the service. It can, and we find sevaral options, settling on one that is both open and near our favorite coffee shop.

Years ago I wrote about neighborhood boundaries, and familiarity. Building that knowledge again in the Mission I think of how transportation defines it, how bicycles expand it and reward casual exploration due to the low cost of going one more block, or an unfamiliar route. Without too much concern for one way streets, traffic, or parking, bicycles are better than cars in this regard. They are better than walking as well, for the limited energy expended to cover six blocks in all permutations. Or our bicycles will be, once they have brakes and tires.

We own four bicycles, though only two are available on this Sunday. The oldest, my Haro, purchased in Venice in 2006, is still in Los Angeles at a friend’s house. Having come with us from LA to Houston in 2008, to San Francisco in 2009, it returned to LA in 2011, less than perfectly suited to the wiggle and San Francisco’s hills.

The second, one of two old Peugeot frames, was damaged by a car on 19th Ave in 2010 and, though having been repaired several times, now needs a new front tire, perhaps wheel, and sits without either in our garage.

Two working bicycles then, just enough for exploration, for a quick trip to the gym and some meandering to a new lunch spot. Just enough to take us to the edges of our neighborhood and to expand those edges. Part of learning each new portion of San Francisco or of our earlier cities is figuring out where the boundaries are, where neighborhoods end and to what distance errands can be run. In the Mission, one of San Francisco’s few flat neighborhoods, our reach is wider than it was in either the Sunset or the Richmond.

Here then, finally healthy and home long enough rebuild the center of a life that has been moved and shaken this year, we seek a bike shop, a place to repair and replace. We find our answer three blocks away, Box Dog Bikes. Checking out the bikes for sale while my brakes are replaced, I think of Roaring Mouse, and of my old resource in Shanghai, the man who opened his front doors every morning, and made keys as well as repaired bicycles. We change cities and neighborhoods, and yet seek the same assistance.

No surprise then that in each the shops are not far, around the corner and waiting to be found.
