A locking device for connecting a suspension device to a front fork of a bike, and includes an adapter which is connected between the suspension device and the front fork. A first part and a second part respectively extend from the top face and the bottom face of the adapter. The second part is inserted in the front fork. Multiple bores are defined through the adapter, and are located around the first part and the second part. An axial hole is defined through the first part and the second part, the steerer tube extends through the axial hole. Multiple bolts extend through the bores and are threadedly connected to threaded holes defined in the crown of the front fork. The suspension device and the front fork can be individually replaced and maintained.
