NOTE: This document describes WHAT and WHY but not HOW. This is due to the fact that we are still in the patenting phase and must not publish functional details, only the design itself.

The bike's suspension rebound propels it forward ..... it therefore pops itself onto curbs ..... it also has no loss of pedaling energy on rough or gravel roads. The suspension also mimics the same body balance as riding a horse.

• The objective of the present invention is to create a 100% recyclable bicycle.
• An additional objective is to eliminate the sources of maintenance such as cables, gears, grease, and spokes.
• Another objective is to eliminate the total number of the bicycle's parts..
• A further objective of this invention is to create a line of bicycles with a bio-psychological ["organic"] design.
• The objective is to provide a look that is so original as to be instantly and "patently" recognizable enough to be used as the bike's trademark look. [see: figure-2 above].

• 100% modular poly-carbonate foldable construction.
• There is no metal used in any part of the design.

  Maintenance

  • There are no bearings, cables or chain.
  • No lubrication maintenance is required.
  • There are no spokes to adjust.
  • The brakes are self-adjusting and require no lubrication.

  Frame

  • A frame is not needed because all parts are mounted to the crank housing.
  • That is where the name "Locus" comes from.

Brakes
• Is a grease-free mechanism,
• It is mounted up high on the bike,
• It is enclosed within the crank housing
• It is designed with antilock load-distributing abilities.
• Braking energy is captured during braking for quick-starts on take-off from a dead-stop.
NOTE: The braking mechanism is mounted inside of a
hollow roller within the Scroller Mechanical assembly.
Transmission
• Is a grease-free continuously variable [CVT] mechanism,
• It is mounted up high on the bike, enclosed within the crank housing
• It uses load-actuated shifting [load adjusts automatically to pre-setable pedal effort].

• Rider has optional ability to use the handlebars as "hand-pedals" or lock them in place using a sliding sleeve.
• The "hand-pedals" move with the foot-pedals in a balanced action as natural as swinging your arms as you walk.

hard to resist.

• Steering is slightly encumbered, so the rider has the option of locking-out this movement "on the fly" and resorting to leg-power alone, but may wish to use this option on long straight sections of travel.

SEAT-ARM

• Connected to the crank housing
• It's suspension is adjustable with a knob behind the seat which turns 90 degrees to be either springy or rigid.
• The seat-arm also functions as tire-pump using the rider's weight. The reason for this is that the tires used are conventional. We are not yet ready to release our airless tire design. The weight of the rider's body multiplied through the leverage of the seat-arm provides the easiest effort possible in pumping the tires.
• The seat also raises and lowers automatically according to the "attitude" of the bike's swing-arms ["gimble" effect].

SWING-ARM

• Both front and rear have off-set single arms with both their rake and trail adjustable.
• The front-arm lengthens the wheelbase as the weight shifts to the front [to prevent "endos"] and the rear-arm lengthens the wheelbase as the weight shifts to the back [on hill climbs].
  • Drive
    • Belt driven two-wheel drive that is preload during braking for quick-starts on take-off from a dead-stop.

  • Suspension
    • Requires no maintenance nor lubrication
    • It is hinged at crank-housing providing ~8 inches of travel at each wheel.
    • The suspension rebound also moves bike forward.
    • Additional suspension option in seat-arm.

PEDALS

• Pedal-arm has adjustable leverage and are designed to make it easy to walk beside without shin-banging.
• The pedal arms are opposite to the leverage of the rider's knee to take the load off of the knee joint.
• As you push one pedal down, the other pedal comes up.
• If you push both pedal arms down the braking is engaged. If one is already down, then holding it down while pressing the remaining one down engages the braking

WHEELS

• Hubless "Rim-Rider" style wheels in a Scroller-Mechanical configuration.
