Anyone have recommendations for Taiwan? With those mountains there's got to be some good stuff. Preferably in the Taichung/central area of the country, but I'll also probably make at least one trip to Taipei and another trip down to the Kending area.

Also, anyone know of somewhere to rent a decent bike? I don't particularly want to drag my bike all the way over. I'll have access to a low end Giant HT, but I'm not sure it how well it would hold up on rockier trails.
