A scooter includes front and rear frame parts coupled together through a pivot unit so as to permit turning of the rear frame part relative the front frame part. The front and rear frame parts are respectively formed with front and rear absorber-mounting members which are respectively disposed frontwardly and rearwardly of the pivot unit. Left and right shock-absorbers have front ends pivoted to the front absorber-mounting member, and rear ends pivoted to the rear absorber-mounting member. Each of the left and right shock-absorbers extends inclinedly and upwardly from the rear absorber-mounting member to the front absorber-mounting member so as to absorb shocks smoothly from vertical and horizontal directions.

1. A scooter comprising:a front frame part having a horizontally extending base with a rear coupling end, and a front absorber-mounting member that is disposed adjacent to said rear coupling end and that projects upwardly from said base;front wheel rotatably connected to said front frame part;a pivot unit;a rear frame part having a front coupling end pivoted to said rear coupling end of said front frame part through said pivot unit so as to permit turning of said rear frame part relative to said front frame part, said rear frame part further having spaced apart left and right wheel-mounting arms extending rearwardly from said front coupling end in a transverse direction relative to said pivot unit, and a rear absorber-mounting member which is disposed adjacent to said front coupling end, which is fixed to said wheel-mounting arms, and which extends upwardly from said wheel-mounting arms;a rear wheel connected rotatably to said wheel-mounting arms of said rear frame part; andleft and right shock-absorbers having front ends pivoted to said front absorber-mounting member, and rear ends pivoted to said rear absorber-mounting member, each of said left and right shock-absorbers extending inclinedly and upwardly from said rear absorber-mounting member to said front absorber-mounting member so as to absorb shocks from vertical and horizontal directions. 2. The scooter as defined in claim 1, wherein said pivot unit is disposed between said front and rear frame parts, and includes left and right knuckles defining said front coupling end of said rear frame part, an outer sleeve fixed to said rear coupling end of said front frame part and extending between said left and right knuckles, an inner sleeve disposed rotatably within said outer sleeve, left and right bearing members disposed respectively in said left and right knuckles, and left and right bearing retaining seats disposed respectively in said left and right knuckles and pressing said left and right bearings to abut against opposite ends of said inner sleeve, and a shaft inserted through said left and right bearing retaining seats, said left and right bearing members, and said inner sleeve so as to permit rotation of said rear frame part relative to said outer sleeve and so as to result in smooth absorbing actions of said left and right shock-absorbers when said scooter encounters a shock. 3. The scooter as defined in claim 2, wherein each of said front and rear absorber-mounting members has left and right brackets, said front and rear ends of said left and right shock-absorbers being pivoted to said left and right brackets of said front and rear absorber-mounting members, respectively. 4. The scooter as defined in claim 3, wherein said front frame part has a front coupling end opposite to said rear coupling end of said front frame part and formed with a generally U-shaped handle-mounting seat that has a base with two opposite ends, and a pair of spaced apart lugs extending upwardly from said opposite ends of said base, said scooter further comprising a front fork extending downwardly from said base to carry said front wheel, a handle pivoted to said lugs and extending upwardly therefrom, and a quick-release locking device including a pair of aligned curved slots respectively formed in said lugs and confined by slot-defining walls, a plurality of engaging grooves formed in said slot-defining wall of at least one of said lugs, a spring-biased shaft inserted movably through said slots in said lugs and said handle, an engaging tongue fixed to said spring-biased shaft, and an operable lever connected to said spring-biased shaft so as to move said spring-biased shaft between a locking position, in which said engaging tongue extends into and engages one of said engaging grooves so as to prevent rotation of said handle relative to said handle-mounting seat, and an unlocking position, in which said engaging tongue retracts from said one of said engaging grooves so as to permit rotation o f said spring-biased shaft together with said handle along said curved slots and so as to permit said engaging tongue to move to a selected one of said engaging grooves, thereby permitting position adjustment of said handle relative to said handle-mounting seat. 5. The scooter as defined in claim 4, wherein each of said front and rear wheels includes an axle, a wheel hub extending radially and outwardly from the axle and having two symmetric halves coupled together to define an annular tire-receiving groove, and a solid tire having a mounting portion that is mounted securely in said tire-receiving groove. 6. The scooter as defined in claim 5, wherein said axle of each of said front and rear wheels includes two halves that are integrally and respectively formed with said symmetric halves.
