The invention discloses a bike used in a mountain city. Due to the adoption of a novel structure of a front steering part of the bike used in the mountain city and a novel operating method of a pedal of the bike, the bike can be easily, safely and more reliably ridden on an uphill/downhill road at a high speed. The bike is absolutely different from the current bike in the world in driving effect. The technical problems existing in the current bike can be solved. The current bike has the following technical problems that (1) the driving speed is low and a user feels laborious; (2) the current bike is difficultly ridden on an uphill road; (3) the driving speed is a little low, so that a handheld bike faucet swings left and right or deflects. The technical scheme for solving the technical problems is characterized in that the current chain bike in the world with the structure that two short pedal arms of a front single wheel rotate at 360 degrees to ride is changed into the chain bike with the structure that two long pedal arms of two front wheels are respectively released up and down and pedaled within a 100-degree turning angle. The time interval when the two pedals are respectively released and pedaled is continuous, turning perimeter is completely transferred by the chain, continuous transmission force is applied to a rear wheel, the front wheels are pushed to be easily and safely driven on various roads in urban and rural areas and the user does not feel laborious.
