The invention discloses a structure for connecting a hub with a disc seat of a bicycle. The structure comprises the hub and the disc seat. A retaining portion which is in the shape of a protruded ring, an outer thread which extends axially and of which the outer diameter is less than the retaining portion, and an axle are sequentially arranged at one end of the hub, the disc seat is in the shape of a C-shaped ring seat, a slot is arranged at the C-shaped opening, a lock catch thread lock is used for driving the slot to form a gap with different tightness at the C-shaped opening and further change the size of the inner diameter of the disc seat, an inner thread is connected with the outer thread, thus firmer thread connection is guaranteed and loosening is not easily caused, the connection way of one end face of the disc seat can be changed along with the six-hole type and the central locking tape of a braking disc, to allow the braking disc to be positioned at the disc seat and the hub, therefore the hub in the single type is applicable despite of different functions and types of the braking disc and a V-shaped caliper brake, and thus the high cost caused by manufacturing hubs in different types is lowered.
