To provide a three-wheel bicycle which allows a user to easily straddle over a saddle of a three-wheel bicycle.SOLUTION: A three-wheel bicycle comprises: a front wheel 92 and two rear wheels 91; a frame 2; and a brake device 8. The frame 2 comprises: a front frame 21; a rear frame 28; and a coupling frame 32. The front wheel 92 is attached to the front frame 21. The rear wheels 91 are attached to the rear frame 28. The coupling frame 32 extends in a cross direction in plan view, and couples the front frame 21 and the rear frame 28. The coupling frame 32 is connected to any one of the front frame 21 and the rear frame 28 in a manner of being capable of rotating around an axis extending along a longer direction of the coupling frame 32. A brake device 8 comprises: a rear wheel brake 81 which can be switched between a brake position for braking rotation of the rear wheels 91 and a non-brake position; and a holding part 85 for holding the rear wheel brake 81 to the brake position.SELECTED DRAWING: Figure 1
