This is not the correct forum. You should re-post this in the general discussion, but just from reading the description on the Amazon page, it seems like a very poorly done translation from chinese into english. Is there a tyre on the bike. The tube should correspond with the size on the tyre (eg. 700X28). If there is no tyre, purchase the correct tyre, then the tube
BTW, I would not have purchased this bike at any price
