Disclosed is a folding bicycle, including: a front wheel, a rear wheel, a handlebar, a main frame, a support frame, a pedal mechanism, a first safety clamp, and a second safety clamp, the first safety clamp being configured to secure relative position between the support frame and the main frame; and a second rotating shaft is disposed between the through-hole and the position where the main frame joins with the handlebar. The folding bicycle disclosed offers an advantage of portability.

Various embodiments provide for a bike-supported communication network that manages and facilitates communications between components of an electric bicycle and a wireless network. In some embodiments, the systems and methods determine that a mobile device associated with the electric bicycle is in contact with a mount disposed on the electric bicycle, and cause a lock assembly to unlock the electric bicycle in response to the determination that the mobile device is in contact with the mount.

Various embodiments provide for a bike-supported communication network that manages and facilitates communications between components of an electric bicycle and a wireless network. In some embodiments, the systems and methods perform security actions for electric bicycle in response to potential theft or tampering events at the electric bicycle. The systems and methods can select actions to perform based on information from multiple different sensors, from polling sensors or components of the bicycle for information, based on a context of the event, and so on.

Various embodiments provide for a bike-supported communication network that manages and facilitates communications between components of an electric bicycle and a wireless network. In some embodiments, the systems and methods provide a bike-supported communication device that communicates with a wireless network via one or more wireless communication protocols, where the communication device is configured to manage communications between the wireless network and various components of the electric bicycle. The communication device can include a bicycle communications component that facilitates communications between the communication device and components of the electric bicycle, and a network communications component that facilitates communications between the electric bicycle and the wireless network.

A saddle clamp for a bicycle includes a rail clamp, and a first and a second post clamp. The rail clamp includes a first rail clamp body configured to engage at least a portion of a first rail of a bicycle saddle, and a second rail clamp body configured to engage at least a portion of a second rail of the bicycle saddle, wherein the first and second rail clamp bodies are configured to cooperate to urge the first and second rails towards each other. Each post clamp is configured to engage a bicycle seat post, with the first and second post clamps disposed between the first and second rail clamp bodies, wherein the first and second post clamps are configured to exert a compressive force on the bicycle seat post in response to the first and second rail clamp bodies urging the first and second rails towards each other.
