A plurality of branch support sheets 333 are provided between two adjacent radial branches 332, and the branch support sheets 333 are also integrally formed with the adjacent radial branches 332.

[0035] There is a support gap 335 between two adjacent branches 333, and there is also a support gap 335 between the support branch 333 farthest from the center part 331 and the outer ring 334, so that the front wheel shock absorber 320 has multiple support gaps 335 in the same radial direction, further optimizing the force conduction path.

[0036] The central portion 331 , the radiating branches 332 , and the branch support pieces 333 are made of the same rigid material.

The rotating shaft 410 is connected to the rear axle 114 and is rotatably connected to the rear axle 114 , so that the rear tire 420 rotates relative to the rear axle 114 .

[0040] The rear wheel assembly 400 further includes a fastener 430 , which is connected to the rear tire 420 until it is fixedly connected to the rotating shaft 410 , so as to maintain the coaxiality of the rear wheel assembly 400 .

[0041] The front wheel assembly 300 further includes two pedals 340 . The pedals 340 are disposed on both sides of the front tire 310 , and the pedals 340 are connected to the central portion 331 .

[0042] The pedal 340 includes a pedal body 341 and a pedal shaft 342 , one end of the pedal shaft 342 is connected to the center portion 331 , and the other end of the pedal shaft 342 is rotatably connected to the pedal body 341 , so that the front tire 310 can be driven to rotate by stepping on the pedal body 341 .
