AI Technical Summary

Problems solved by technology

Existing bicycles are limited by the conditions of use. The length of the drive crank between the pedals and the drive center shaft is fixed, so the torque of existing bicycles is fixed.
The existing bicycle with fixed drive crank can adapt to the height of 130 centimeters. People who are higher than 130 centimeters can not play the maximum effect of the cyclist. When running into the wind and going uphill, the cyclist will feel very strenuous.
Existing bicycles are not designed with front, rear, left, and right bumpers, signal lights and rearview mirrors, so traffic accidents often occur and cause casualties of cyclists
Existing bicycles are not designed with tarpaulins, so the bicycles do not have rain, sun and wind protection functions

Embodiment Construction

[0009] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0010] The present invention is a bicycle that can adjust the length of the drive crank to change the torque, such as figure 1 As shown, the drive crank is manufactured as two pieces that can be separated. One end crank that is connected together with the driving center shaft is made into a square cylinder, and a circular hole is arranged at the top of the square cylinder to be used for being connected with the other end. The crank at one end connected with the pedal pedal is made into a square tube, and a plurality of round holes are used to connect with the drive center shaft on the square tube. By increasing the height of the driving central axis from the ground, adjusting the length of the driving crank to change the torque, so as to maximize the effectiveness of people of different heights. As the drive crank length increases, the torq...

Abstract

The invention discloses a variable-torque bicycle with bumpers, signal lamps and awning driven by multiple persons. The efficiency of the bicycle can be increased by increasing torque by adjusting length of a driving crank. Front, rear, left and right bumpers, signal lamps and lighting lamps are arranged to protect the safety of riders; the awning is arranged; and thus, the bicycle has rain-proof, sun-screen and wind-proof functions.

Description

technical field [0001] The present invention has variable torque, has front, rear, left and right bumpers, turn signals, folding tarpaulin and bicycles ridden by multiple people. Background technique [0002] Bicycles are low in price, use no fuel, protect the environment, are not restricted by traffic congestion, are easy to maintain and can exercise, and are loved by people. But existing bicycle is that the cyclist relies on controlling the center of gravity to maintain balance, so the drive center shaft is fixed at the bottom most in the middle of the bicycle frame. The length of the drive crank between the pedal and the drive center shaft is fixed, so the torque of the existing bicycle is fixed. The existing bicycle with fixed drive crank can adapt to the height of 130 centimeters, and the maximum effect of the cyclist can not be brought into play for those who are higher than 130 centimeters. . Existing bicycle does not design front and rear left and right bumpers, s...
