A direct transmission for a bicycle has a box disposed on a rear axle on which a conical gear is disposed. A shaft is coupled to the conical gear so as to drive the hub. A spring biases the shaft toward an annular flange in order that the shaft cannot move longitudinally relative to the box. A hole with a notch is formed in a rear and outer end of the box. The rear axle can be inserted through the notch into the hole. A sleeve nut is engageable with the rear axle so as to stably retain the rear axle in position.
