荷兰采购需求：自行车、自行车零件、三轮车、滑板车、儿童玩具、学步车

I'm reaching out to express my interest in sourcing bicycle parts for our upcoming projects. We're looking for a reliable supplier that can offer a wide range of components, including but not limited to frames, gears, brakes, and wheels. It would be great if you could provide a comprehensive catalog that showcases your available products along with their specifications. Additionally, I'd appreciate receiving your quotations for the various parts so that I can evaluate them for our purchase order. We're particularly focused on quality and affordability, and any insights into bulk purchase discounts would also be valuable. Please send the information to my email at your earliest convenience. Thank you!
