When stepping on when foot-operated, the brake attaching parts travels forward downwards, and drives connecting strap and travel forward, and connecting strap promotes brake iron and props up to travel forward and embed in the brake disc, and trailing wheel stops operating; Unclamp foot-operated after, the brake attaching parts under the effect of vehicle frame inner spring, is got back to the home position again, brake iron props up from brake disc throws off, trailing wheel begins to rotate.
In a preferred embodiment of the present invention, for satisfying the go-cart person of different heights, be provided with transfer bar mechanism on the rear connection pipe of described vehicle frame rear end, described transfer bar mechanism comprises and pushes away spindle clamp sheet, lower handle pipe, upper handle pipe and bending handle, the described handle pipe that pushes away is fixed on day fluffy pipe by pushing away the spindle clamp sheet, described upper handle pipe is connected with lower handle pipe by the bending handle, and upper handle pipe and lower handle pipe can be carried out the adjusting of different angles by the bending handle.
In a preferred embodiment of the present invention, more firm for making day fluffy pipe, and can inwardly fold, fluffy pipe was two in described day, a day fluffy pipe is arranged on the vehicle frame both sides.
The invention has the beneficial effects as follows: the present invention adopts bi-directional synchronization brake holding system flexible operation, and is easy to use, superior performance, and two-wheeled brakes simultaneously when brake, stops more steady, safer; Increased anti-hypsokinesis support, driving stability safety when having avoided the bicycle sharply turning, is connected to the trailers rollover of bicycle back.
