The following deals with the way Power Rider works and its construction. It has been updated on 1/2/2018
It is completely obvious that the cycling action involves movement yet here we are 200 years on still trying to ride on a fixed saddle!

Nobody as yet has produced a product to cope with the movements in musculature and bone structures that occur when cycling.
Power Rider replaces the saddle allowing you to ride the bike in a free and different way.
HOW POWER RIDER WORKS.
Power Rider is best described as a moveable support rather than a seat or saddle because it moves with the rider for any movement, to provide support for any riding position.
It is a bilateral support with two seat parts that can move independently.
The basic concept is that the rider is balanced on, and movements occur around, a single pivot point that can move in any direction.
I have given it a bright orange colour so it can be easily seen and identified.
The balance occurs:
CONSTRUCTION OF THE POWER RIDER.
This is the Power Rider with the axle (a bicycle back axle) pivoting in rubber.
I have given it a bright orange colour so it can be easily seen and identified.
The balance occurs:
-both forwards and backwards, on unique and comfortable seat parts, that turn on an axle;
-sideways across the bike by the axle pivoting in rubber;
-vertically on a spring and rubber suspension.
See the video of an earlier Power Rider (and another of my inventions called Steady Steer) that illustrates the basic unchanged principles and advantages of Power Rider at https://youtu.be/6iF08rGNJds and see the Racing Power Rider at https://youtu.be/xF4mmBL4SSg. (and go to badsaddle.blogspot.com to compare the saddle with Power Rider.)

You can ride and balance on the bike like this because the force of riding occurs through the body's natural pivot point at the hips which acts directly in line with the axle and single pivot point.
Any movement is possible and unrestricted circular hip movements can occur.
The bike itself travels a straighter path since unlike fixed saddles, Power Rider moves with the rider, allowing free natural riding movements, and these rider movements are not transmitted to the bike frame.
As more power is applied, Power Rider rises under the action of the spring, because an increase of pressure on the pedals, results in a decrease in the downward weight pressure on the seat parts.
The ride on Power Rider therefore, becomes softer with any increase in power and it provides constant support for a gradation of positions that are determined by the power applied.
At a certain position the bike becomes easier to ride and movement of the seat parts is minimal.
This, I believe, is the optimum position for riding the bike. It cannot be obtained on the saddle because of the restriction of the nose.
At full power the rider is forced entirely backwards into the inclined Power Rider with little or no weight acting directly down.
The rider does not move backwards however, because as the seat parts rise, they increase in tilt to hold the rider.For racing it is possible to ride continually and comfortably on the down bars.
In this position and with the backwards force now dominant, the size of the seat parts can be reduced.
It is the ability of Power Rider to provide comfortable support in all riding positions and adjust for a change of force from a downward sitting force to a backwards riding force, or anywhere inbetween, that makes Power Rider unique and I believe the best bike seat in the world.
This is the Power Rider with the axle (a bicycle back axle) pivoting in rubber.
The rubber (a section of webbed matting) sits in a slot in an upper bent metal tube(the seat post), which is laterally compressed and shaped. It is held in position by wire attached to it that extends down through the upper seat post and is clamped at its exit.
Changes in this clamping position allow horizontal adjustment of the webbed rubber in the slot and movement of the seat parts.The best position seems to be to have the axle 2cm back from a line through the centre of the seat stem. Additionally to the clamp, a small bolt that screws through the rubber and fastens into the metal tube of the seat post can be used.
The axle assembly is compressed between 2 nylock nuts to provide sufficient friction to hold the seat parts in position when riderless.Variation of the length of the tubing between the seat parts allows lateral adjustment of the seat parts for a smaller or larger buttocks.This adjustment increases comfort by supporting the outer gluteus maximus muscle. It is this support on the outer edges of the buttocks, using the riders own natural padding, that uniquely contributes most to the comfort of the Power Rider.
The large seat parts are textured to grip the rider so there is little movement between rider and seat.
Holes in the seat provide some ventilation.
Mounting the axle in rubber increases the softness of the ride and an unexpected result occurs.

Since you are riding in a rhythmical action each movement in the rubber builds onto the next as the rubber rebounds with the motion.Like pushing a child on a swing,once started this motion continues with little effort like the Power Rider driving itself.
So we now have a Power Rider with motion assist!
This idea also extends to other rotations in the design.Namely the turning of the seat parts and seat post. The seat post sits directly on a rubber buffer below the clamp within the seat stem so as it turns it moves and distorts this rubber, with the rubber also holding the seat in position when riderless.

This is the RACING POWER RIDER using the similar principles but with a reduction in the size of the seat parts made possible because there is little sitting at full power..

This shows the seat parts and the placement of the clamp below the seat post.

These must give sufficient upward force to provide a higher position as the seat is leaned against when riding up hills and at full power.I am now trialling a TF1890 Yellow Die Spring for the main spring.
The smaller thicker spring caterS for different heavier body weights.
This can be followed by a solid plastic tube spacer if needed.This is used to create a slight compression in assembly and determines the working range of the springs and the maximum height of the Power Rider. Whether or not it is needed depends on the length of the seat stem.
A wire (fencing wire) runs through all of these from where it is hooked into the webbed rubber supporting the axle at the top.
All this fits in the seat stem assembled under slight compression of the springs, followed by a rubber buffer and hex head bolt and nut with a hole through the bolt so it can be clamped onto the wire.
Two light springs are placed inside the seat post to protrude through holes and act against the inside of the seat stem.These prevent a rattling of the seat post within the seat stem when riderless.

An improvement and simplification for Steady Steer is to leave the bottom bearings in place and simply replace the top bearings with the rubber and conical washer.It is also easier and better to use a plastic conical washer.Turning occurs of the metal on the plastic without noise.
I had been using rubber 5mm in diameter but after a time about 3000km the rubber breaks internally with the flexing and an annoying rubber on rubber squeak develops.I am now using 3mm diameter rubber to cut down the rubber movement and internal breakage.For more detailed information about Steady Steer go to
