Abstract: The bicycle seat security device is secured to the seat post of a bicycle seat and operates to receive a bicycle lock. With the bicycle lock in place, the bicycle seat security device prevents access to a seat retaining bolt which is mounted in the bicycle seat security device. This device includes a lock retaining section having a lock bore extending therethrough to receive a bicycle lock with a fastener receiving opening formed in the lock retaining section and extending therethrough to the lock bore. The fastener receiving opening is sized to permit passage of the seat retaining bolt which is mounted in a mounting unit formed on the lock retaining section on the side of the lock bore opposite to the fastener receiving opening.

Abstract: An apparatus 10 is provided for connecting a wheel to a bicycle frame 14. In particular, a hub 16 is rotatably connected to the fork portion 12 of the bicycle frame 14. A drawbar 18 acting as an axle passes through a central longitudinal bore in hub 16 and is captured at each end respectively by a cap nut 38 and housing 36. Intermediate the cap nut 38 and fork 12 is a lockdown washer 28. Lockdown washer 28 includes a raised portion extending within the fork portion 12 whereby rotation therebetween is prevented. A raised knurled portion extends longitudinally from the lockdown washer 28 and mates with a corresponding recessed knurled portion within the cap nut 38. Correspondingly, between the housing 36 and fork portion 12, a second lockdown washer 26 is disposed. The lockdown washer 26 also includes a raised portion 30 extending into the frame 12 whereby rotation is prevented therebetween.
