An improved baby seat structure for bicycles has mainly a back unit, a seat unit connected to the back unit via coupling means and an L-shaped frame, an extensible handle set attached to the rear side of the back unit, two front-wheel bracket sets pivotally joined to the front of a seat body of said seat unit thereof, a base unit attached to the underside of the seat unit, a pair of rear-wheel bracket sets pivotally engaged with a wheel pivot body of said base unit via splined couplings, a mounting seat secured to the underside of the base unit, a plurality of inserted pins and screws, and a long round rod to engage the wheel pivot body thereof with a base body mounted thereon. Via a pair of eccentric means, the extensible handle set can be adjusted in height for use. Via the rotation of a pair of stopper blocks, up and down, and adjusting blocks, to and fro, the base body thereof can be swung up or down upon the wheel pivot seat thereof to relocate the L-shaped frame for adjusting the angle of the back unit thereof. Via rotary heads and rotary wheels, the front-wheel and rear-wheel bracket sets can be either let down or folded up respectively for different uses such as a stroller or a normal baby seat. Via triangular fixing pieces and wing panel, the mounting seat thereof can be fixedly fastened to a rear carrier of a bicycle for the use of a bicycle baby seat.
