Maybe because I'm in Toronto? But if that's the case, perhaps you should have an "only works in the US" message pop up once your geolocation sees that I'm outside the country.
Since you mentioned google, I ran the same search on google maps, and all kinds of stuff came up for bike brakes. Now, much of it was noise, which is what your product is likely designed to deal with, but at least I got something!
From a design standpoint, looks clean and clear. Easy to navigate.
Best of luck! Hope it takes off.
