A bicycle wheel quick release device capable of being combined with a tool has a quick release assembly and a handle. The quick release assembly has a shaft, an axial hole, and a cap. The cap has a receiving groove communicating with the axial hole. The handle is capable of being received in the axial hole and the receiving groove and has at least two tool portions. Any one of the at least two tool portions is capable of being combined with a threaded component to screw or unscrew the threaded component onto or from an object. Thereby, the handle is a multifunctional tool that can be used not only as a wrench for detaching or mounting the quick release assembly from or onto a bicycle frame but also as a wrench for other threaded components.

A device for measuring the pressure of a two wheeler tire comprises: a connector to connect the device to a valve of the two wheeler tire; a valve opener to open the valve, so that in the connected state with the valve, pressurized air flows out of the two wheeler tire through the valve into the device, until the pressure in the device corresponds to the pressure in the two wheeler tire; a pressure measuring device to measure the pressure in the device; and a transmitter to wirelessly transmit information about the measured pressure. A method for monitoring the pressure of a two wheeler tire includes: determining the actual pressure and desired pressure of the two wheeler tire; comparing the actual and desired pressures; and indicating the actual pressure and/or the desired pressure and/or the difference between the desired and actual pressures of the two wheeler tire.

A bicycle accessory mounting bracket includes a first member, a second member and a plug member. The first member has a first connecting pillar with a first sliding slot. The second member has a second connecting pillar. The plug member is inserted into the first and second connecting pillars inserted into each other through the first sliding slot and the through hole of the second connecting pillar. The plug member includes a shell, an actuating member and two abutting members. The actuating member has a wide portion and a concave portion. In the first position, the wide portion is located between the penetration holes, and the abutting members are pushed by the wide portion to enter the perforation holes. When in the second position, the concave portion is located between the penetration holes, the abutting members enter the concave portion, and the first and second connecting pillars can rotate relatively.

A kickstand pad is configured to provide a surface on the ground on which a kickstand of a motorcycle rests to increase the motorcycle's stability when the motorcycle is parked. The kickstand pad includes a support pad, a tether, and a hook or clip. The support pad increases the amount of level surface area on which a free end of the kickstand can rest to avoid the kickstand embedding or piercing itself into the ground or soft pavement when the motorcycle is parked, which can result in a dangerous and/or damaging fall of the motorcycle. The support pad includes notches or winding features that facilitate storage of the tether when the kickstand pad is not in use. The tether may also serve as a visual reminder to the motorcycle operator to pick up the kickstand pad before driving away.

A bicycle container including a main body for containing objects and an engagement member provided on the main body. The engagement member is configured to engage with a pedal of a bicycle to enable the bicycle container to be detachably coupled to the pedal to hold the bicycle in an uptight position.

A rear shifting and drive system, frame drop out, derailleur hanger and derailleur alignment tool provided with an axle attachment adapter/structure, a moveable collimated light source, and a collimated light source positioning linkage. The axle adapter/structure is attachable to a bicycle wheel axle and is rotationally moveable about the axis of the bicycle axle. The light source is moveably coupled to the axle adapter/structure by the light source positioning linkage, to move in a direction substantially parallel to the axis of the bicycle rear axle. The light source is positioned to shine the cross laser simultaneously on the axle or plane of the axle and the system components of the shifting and drive system. A visual vertical alignment of the cogs of the cassette, and derailleur jockey wheels, to each other in each shifting position, and relative perpendicular to the axle or plane of the axle provides an easy visual aid in assessing the relative positions and orientations of the components. As such, worn, damaged, bent, broken or maladjusted components of the shifting and drive system can be assessed and adjusted, repaired or replaced without disassembly of the shifting and drive system.
