Disclosed is a high performance recumbent bicycle that allows the rider to add substantial hand power by pulling the fork mounted crankset, about the steering axis, into foot pedal thrusts. The effect is superior to standing to pedal an upright bike, because the rider can provide power immediately, while remaining comfortably, safely and aerodynamically seated. Effective pedal force reaction is provided. Torque and work based hand power input methods are used. No supplemental mechanism is necessary. An embodiment has front wheel drive, a vertical steering axis, crankset offset ahead of the steering axis by a crankarm length, fork assembly rigid in torsion to rider hand and foot forces applied in opposition, and indirect steering mechanism which enables rider, grip, and pedal location and orientation for effective supplemental hand power input, and control of pedal forces on the steering. The enhanced steering control allows use of an aerodynamic disk front wheel.

A handguard system for a handlebar of a bicycle is provided and includes a handguard article having a handguard first end communicated with a handguard second end via a handguard center portion, wherein the handguard second end is configured to associate with the handlebar. The handguard system also includes a handguard collar, wherein the handguard collar includes a handguard collar structure which defines a collar cavity configured to contain the handlebar and having a collar cavity diameter CCD which is configurable between a first collar cavity diameter CC.sub.D1 and a second collar cavity diameter CC.sub.D2. and Additionally, the handguard system further includes a handguard mounting device, wherein the handguard mounting device is configured to securingly associate with the handguard first end and the handlebar, wherein when the handguard article is securingly associated with the handlebar, the handguard center portion is configured to cover a portion of the handlebar.

A handlebar foldable mechanism and a tool for riding instead of walk are provided. The handlebar foldable mechanism includes a base, a stem, a first locking assembly, a lever and a second locking assembly. The base is provided with a first snapping groove, the stem is connected to the base and is pivotable between an unfolded position and a folded position, the first locking assembly is pivotably connected to the stem and is configured to be engaged with the first snapping groove when the stem is pivoted from the folded position to the unfolded position, the lever is pivotably connected with the base, the second locking assembly is mounted to the lever, and the second locking assembly is configured to be connected to at least one of the base and the stem when the stem is at the unfolded position.

Systems and methods directed to a steering column clamp for securing a steering column to a steerer tube are provided. The steering column clamp may include an internal clamp portion having longitudinal slot disposed at least partially between a first end of the internal clamp portion and a second end of the internal clamp portion. The steering column clamp may include a tightening mechanism, when engaged, causes the internal clamp portion to compress about a steerer tube placed in a first end of the internal clamp portion. The steering column claim may also include an exterior wall portion at least partially enclosing the internal clamp portion such that a hollow portion is between the internal clamp portion and an internal surface of the exterior wall portion of the steering column clamp.
