Seat Arm

•  Connected to the crank housing

•  The seat arm is oval so it is flexible up-down but not side-to-side.

    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 is 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   [ "gimbal" effect ].




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

    eliminates wobble.

The Organic Brain-Stem Elements


•  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: image above ].


•  100% modular poly-carbonate foldable construction.     

•  There is no metal used in any part of the design.





•  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.



•  A frame is not needed because all parts are mounted to the crank housing.

•  That is where the name "Locus" comes from.


Crank Housing

•  The crank housing encloses brakes and transmission

    to protect from water, dirt and gravel.


•  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.

•  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-settable pedal effort.




•  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 ].




•  Belt driven two-wheel drive that can be preload during braking

    for quick-starts on take-off from a dead-stop.

•  The front wheel can be disengaged from the drive system at will.


•  Requires no maintenance nor lubrication

•  It is hinged at crank-housing providing ~8 inches of travel at each wheel.

•  Additional suspension option in seat-arm.

•  The suspension mimics the same body balance as riding a horse.

•  The bike's suspension rebound propels it forward ;

    it therefore ....

                •  pops itself onto curbs and over rocks.

                •  suffers no loss of pedaling energy on rough or gravel roads.



•  The pedals are designed so that the rider uses his RUNNING MUSCLES

    for a stronger and more natural motion.

•   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, pressing the remaining one down

    engages the braking.


This document describes WHAT and WHY but not HOW. 
because the Locus Project is still under IDS-Research 
and is not completely transfered to IDS-Development.
