7 results about "Mountain biking" patented technology

The disclosure relates to a bicycle, in particular a mountain bike, comprising a main frame with a subframe sprung to the main frame. The rear wheel is mounted on the subframe. The bicycle includes a derailleur system with a cassette having a plurality of sprockets. The chain is guided over a guide pulley mounted above the bottom bracket. The guide pulley is pivotally mounted on the main frame or subframe.

The utility model relates to a bicycle technical field, a kind of multi-connecting rod formula mountain bike rear shock absorbing structure, including frame, the symmetric "V" shape and the opening is set to the support plate of being set up upward in the middle two sides of one end of frame, shock absorber is equipped in one end between two support plates, the top of shock absorber is rotatably connected with the end portion of support plate by pivot, and the bottom of shock absorber is rotatably installed on fixed frame by pivot, and fixed frame is fixed with frame;Striated first connecting plate is rotatably installed on the other end of support plate by pivot, and the top of the other end of first connecting plate is provided with first slot, and the bottom of first slot is arc surface.The utility model is cooperated with the fixing mode of sleeve and locking nut by the cooperation of first slot and second slot, when rear wheel is disassembled, just need to loosen locking nut and lift second connecting plate, do not need to forcibly pull along the connecting shaft axial direction, significantly simplify the replacement process of rear wheel, and it is labor-saving and efficient to operate.

This utility model belongs to the field of mountain bike front fork shock absorption technology, and particularly relates to a mountain bike front fork shock absorption device, including a front fork body, two shock absorption device bodies and two locking structures, two first through slots, which are respectively opened on the side of two fixing frames near the shock absorption device bodies; four sets of rotating components, which are respectively set inside the four housings and are used to drive eight threaded rods to rotate simultaneously; and four sets of reinforcing components, which are respectively set outside the two shock absorption device bodies and are used to fix the two shock absorption device bodies. Through the above structure, the shock absorption device bodies can be reinforced, thereby dispersing the impact stress generated during riding, reducing the wear of internal components, extending the life of the shock absorption system, and making it suitable for high-intensity riding or competitive scenarios, thus facilitating user use.
