智利采购需求：公路车、儿童车、平衡车、车把、城市车、折叠车

I'm looking to source various bike parts to support our production line. Specifically, I'm interested in wheels, brakes, chains, lights, saddles, and any other key components that contribute to bike assembly. The quality of these parts should be at least medium grade or higher to ensure durability and customer satisfaction. Please provide your product options, pricing, and lead times. Looking forward to your prompt response!
