My bicycle was bought at Castille's and the brand name is Hurricane. The most important thing is to buy only the bike with stainless wheels and aluminum spokes. Otherwise the salt will soon destroy the steel wheels. A one speed bike works the best in San Pedro...the gears also have problems with the salt air.
Beware also of the frame rusting from the inside. I know of a nasty accident when the frame just disintegrated when the bike hit a bump. A good point in favor of the Treks, as their frames are aluminum.
There aren't decent chains available here. In Britain you can get nickel-plated rustless chains (made in Germany I think) at a fraction of the cost of stainless steel ones, but I've never heard of them here.
But none of this matters for a bike used in a more user-friendly environment. The main problem there with the Chinese bikes is that the metal is low grade and soft, so wears quickly.
We love our Hurricane bikes. We bought two, over 2 years ago. They live outside. They are our exclusive form of transport. They are still alive and will probably last another six months. If you look after them on a very basic level, they are surprisingly hardy bikes.
We only had one bike go missing and that turned out to be a drunken misunderstanding on the taker's part. It was returned the next day.
We usually always lock them if they are where we can't see them. If we use them at night, we don't leave them anywhere obvious. That is about the only things we do. Perhaps we are lucky but we often go shopping with our bikes, forget to lock them and leave shopping in the basket as we go from store to store. Have never had anything go missing. Maybe our bikes just give off good vibes. Who knows?
