德国采购需求：跑步机、折叠式跑步机、可折叠跑步机、坡度跑步机、家用跑步机

Could you please send me your product catalog along with the pricing details for walking pads? I'm an Amazon seller interested in expanding my product range and would love to understand your offerings better. Additionally, could you let me know the minimum order quantity for first-time buyers? I'm particularly looking for models with a quiet motor, speed control, and the specified running belt size. Any information regarding the max load and display metrics would also be appreciated. Thanks!
