Problems solved by technology

[0003] However, in conventional bicycle frames, these pipe members are fixed by mutual welding, and when welding failure occurs, the connection can be easily damaged, and there is a risk of safety accidents due to weak durability.
[0004] In addition, although folding or folding bicycles are marketed in various forms for the convenience of storage or transportation of bicycles, and in order to reduce the length or volume of the frame, there is no such thing as taking into account the age or height of the occupants. A bicycle that can adjust the distance between the front wheel and the crankshaft of the pedals

Abstract

The invention relates to a new-concept bicycle frame structure. More specifically, the bicycle frame structure is provided with an upper face and wavy parts; the upper face is attached to a seat frame connected with a bicycle frame vertical pipe in a connected mode, the wavy parts enable a jaw to reciprocate up and down through linkage of a cam rod and a safety rod and are fixedly formed on the upper face of a top frame, and therefore the structure of the seat frame can be arranged at any position; and at this time, a lower frame of one side and a lower frame of the other side of an acceleration device which is attached to the seat rack in a connected mode and has specific characteristics in the speed aspect of the bicycle are also attached to the seat frame. In addition, the new-concept bicycle frame structure is provided with a fork frame forming a structure for adjusting the height of a bicycle steering handlebar and enables the fork frame to form a structure connected with the top frame in a non-welding mode so as to attach to a bicycle rear wheel, and the lower frames slide on the top frame in a reciprocating mode and retract and expand towards any position.

Description

technical field [0001] The present invention relates to a bicycle frame structure, and more specifically, to a bicycle frame structure of a new concept in which the distances between a seat and a rear wheel can be adjusted arbitrarily with respect to a front wheel. Background technique [0002] In general, the bicycle frame is roughly in the shape of a diamond, and includes: a front tube, which is connected with a handlebar at the top of the above-mentioned front tube, and a fork with a front wheel fixed at the bottom of the above-mentioned front tube; The upper part of the riser is connected to the seat (seat), and the pedal crankshaft is connected to the lower part of the above-mentioned frame riser; the top pipe is used to connect the above-mentioned front pipe and the upper part of the above-mentioned frame riser; tube and the lower portion of the above-mentioned frame riser; a seat stay for connecting the upper portion of the above-mentioned frame riser and the rear axl...
