Can anyone in Tijuana recommend 2 or 3 good bike shops?

When I go to San Diego I ride the trolley. And with that, I can't go to San Diego to buy a bike because I don't have a car which means I would not be able to haul it from San Diego to Tijuana.

And besides, since I live in TJ I need to learn where 2 or 3 good bike shops in TJ are located, if they exist. I'm defining "a good bike shop" as one that has a good/decent selection of new and used bikes.
