TOP-TEN 4Bikes
fahrRAD       *).  Prevetius modell 2013

Carriages not drawn by buffaloes with heavy, large wooden wheels have pulled China and India into the modern world.

No, the bicycles carrying loads of loads have (and still lead to this day)

brought this era.

fahrRAD-solar  -  Tandem  -  Cargo-bicycle  e.g.:



You will find here a lot of patents free suggestions to expand the bicycles world with accessories. 

So that for example also an all-weather property can be offered relatively cheaply.


This  TOP-TEN 4Bikes  are particularly directed at the bicycle and parts manufacturers




1.) The strenght is to be found in serenity


However, a classic "upright position" requires us a somewhat wearisome, forward curved seat and work; And recumbent bikes position their rider to near over the asphalt.


A high oblique backrest provides e.g. an optimal supportive lean on seating position; Active kicking becomes powerful, efficient and at the same time more relaxed.

When lean on sitting, an anatomical support is provided, with ergonomically optimized pedaling. It makes cycling much more relaxed and safer. The back rest is about 20 cm further back to place. The handles of the steering rod are also brought closer to the driver; And so resembles its location of an "Easy Rider" on a Harley.



Other advantages of sitting comfortably:


#  You have a not so front-wheel-heavy center of gravity and does not crash over the handlebar during an impact.

#  With a safety belt, a real higher safety is achieved. It is anchored on the shell support, which is especially stiff at the edge.

#  The large back rest protects the head area, the shoulders and the hip as far as possible in case of an accident.

#  These arrangements prevent a fall out of the structurally given range.




2.)  fahrRAD gear - rocking instead of cranking


All pedal-lever approaches of the past were too cumbersome or not at all gear-shiftable; And all were directly on the rear wheel axle carried. No one had the market enough enthusiastically and so was not one of lasting success**.


However, a "Rocking lever drive" can on every bike pedal axle be Combined with a only 6 Pcs. Gear shifting.

It is equipped with a freewheel and is mounted on the pedal axle. The eye of the freewheel bearing and the axle ends are thus furthermore form-fitting components. As usual, the lever arms are secured with screws.

The chainring remains fixedly connected to the pedal axis but has no direct contact with the right lever. Instead of the crank, the chain rim is driven here by two lever arms to its usual driving power. Furthermore, the levers are put into a rocking connection by means of a deflection roller (under the seat) and by means of a nylon cable.


On each of the levers there is a pedal-mounted sliding sleeve. Together they provide the pedal function of the lever arms.

For the gear selection, the sliding sleeves are pressed away from the foot pedal (by means of discs, arches or the like located on the outside of the pedal) against a leaf spring tension. The now freely selectable engagement to a clutch relief (made of shafts, teeth; or grit and rubber for stepless operation) which is formed between the lever arm and sliding sleeve, this simple and robust gear shifting results.

Against unwanted displacements, the mentioned arched spring keeps the selected gear pressed on the clutch relief.

This spring is in each case placed across from the pedals, in the 2 mm clearance between the lever arm*** and the sliding sleeve.



The advantages of this circuit are:


#  The "Rockinger" replaces a rear wheel gear and is sufficient as a full-fledged gear shift. The optional combination with a 3-speed chainring makes sense.


In the case of 5 - 7 lever arms gear - optionally three times through the chainrings - this circuit provides an optimal spread ratio - for both mountain and downhill driving.


#  There is no need for a rear wheel gear and the associated Gear shifting on the handlebars - these are quite a several parts! 


#  In the rear wheel finds a free-wheeling and optionally a e-motor place, which is not loaded the chain.


#  This device has only 350 g of sliding sleeve weight. It also does not cause a 2/3-idle with otherwise usual circling leg movement.                  


#  Provides a continuous, direct and highly efficient pedal conversion of the footwork as required; Therefore also higher attainable tempi. Short rocking intervals are maintained as required.


# A Rockinger is easier to learn than the traditional crank handle.


It can be easily practiced and physically well self-sufficient.


#  Both lever arms can also be removed; This allows the change of a defective freewheel.


The whole is inexpensive to produce. And there is a need for replacement of the pedals axle ball bearings.


#  The search for the desired translation ratio is solved constructively with only a few parts. 


And, the free leg selects its course; therefore is also no rocking interruption.




3.)  One-wheel for two-forces     


A optionally lever arm extended beyond the axis point, provides an advanced pedal mechanism for a second driver.

The bicycle frame is only slightly stretchedIf necessary, the second saddle is clicked on the bicycle frame, and a second pair of sliding sleeves with their pedals is clicked (the stearing grips are let into the front back rest frame). These attachments can easily stay at home during single exits.


In the paired operation, the cyclist participates only in the opposite riding rhythm - and each exit becomes a harmonious and perfect work placement. Both have their free choice of course.


This opens up the development and market performance with a new, creative lightweight construction Tandem-fahrRAD! The frame is the result of respective designer-creation of a bicycle manufacturer.



4.)  Oh, my ass


Another innovation, also useful for conventional bicycles, is presented here: Especially in longer journeys, conventional saddles are quite uncomfortable. A saddle can also be formed from two oblong, good-fit thighs / buttocks, which are mounted side by side on one axle. These carry out the bouncing pedal movement of the driver. Such a "saddle pad" increases comfort for both men and women thanks to its noticeable relief in the sensitive step area.






5.)  In case of heat and rain


Who likes to ride a bike in the rain, snowfall or high heat? Hardly anyone!



The fact is that our city, cargo and travel bikes only offer high driving comfort every day if they can protect us from rain or direct sunshine.

An attachable canopy could encourage the car to leave the car more often in the garage - to ride on a bike - see below.


A horizontal weather protection roof protects against sun and rain. On the other hand, it also supplies the bulk of the drive power as a photovoltaic film on the aluminum roof frame or as roll blinds.

The electricity generated on the roof is fed into the solar battery integrated into the fahrRAD frame - in tube. These 150W PV films **** harvest all day, even in diffuse weather conditions, daylight. The approximately 1.1 m² roof creates sufficient energy for a medium travel distance.

The lightweight, removable awning is wind-slippery; In a longer test phase, I drove this one easily, even with strong winds, because even changing winds actually run flat. Also for conventional bicycles such a roof (behind the saddle-ankle or on the handlebar clickable) would be interesting.


The four roof corners conceal the blinkers of a turn-off indicator. The lights fed from the battery should be supplemented by a brake light because of the dangers in today's traffic density. A dawn sensor could take over the reliable on / off switching of night lighting.

A wind- and visibly transparent net-store protects against rain as well as against too strong sun. It is used by

Velcro fastened to the roof frame. The store has sewn a lead band at the bottom hem and is about 55 cm deep enough. The approx. 60 x 180 cm roof can be moved forward about 60 cm in the rain and granted, that everything remains in the dry.


For sporty cyclists, this top can also be enjoyed without an electric drive (covered with perlon instead of PV foil, weighs only about 700g) *****.



6.)  Hand Protection


In order to avoid common microtraumata in the wrist, a cylindrical, elastomeric tube-plug connection could be provided for the shock-relief, in the steering grips and their transitions to the steering bracket. This stiff-elastic bridge could be differentiated on the weight of a person to be available, respectively, different deeply.



7.)  The small cargo


The area behind the oblique backrest provides plenty of storage space for luggage, e.g. also one - two children place. Also conceivable would be a light, removable and lockable stretch-mesh basket with a full-length folding lid, which can be pushed with a light hand after the purchase like a travel bag on four castors. This basket can also be made of light pasture, as a practical   4 wheel drolley.

The children 's seats would also be fastened with a click fastener; They may have side wheels under the seat and a guide bracket that can be pulled out of the back part. Such a child seat would become a stroller after the journey.


With a special frame, fahrRAD could be designed as a cargo wheel with a low-lying and generous loading area. Also conceivable is a three-lane variant (possibly with attachable support wheels raised in travel).

By means of a (PV) rain cover, the transport goods fixed with quick-clamping straps are optimally protected.  



8.)  Tire & wheel - Airless tire? 




My idea of a new type of tire made of a harder rubber compound does not require the usual rim bead wire or fabric inserts; Neither a hose nor internal air overpressure. These types of tires already spring through their hard-walled hard-rubber cross-section (see drawing). In the case of higher loads, however, these tires can still be inflated accordingly.

In addition, a small-sized, medium rolling bead provides the perfectly minimized rolling resistance. The lateral, wide auxiliary ridges, optimized for Gripp, only roll into ground contact when in an oblique position. Inflation and "piss-pecking" are not necessary for this uncladable model.

For tire mounting, this fahrRAD tire has a two-part "screw-on rim", which ensures a perfect and form-fitting tire seat.

And, the wire- and fabric-free material is absolutely unproblematic in recycling and can be recycled as granules!



9.)  Tackling spokes a wheel was yesterday ...


Back-friendly side effect on the newly designed BIKE: the rear wheel can get an effective shock absorption using 12 tapered fever glass bow springs or steel leaf springs instead of still common spokes. The other common shock absorbers for front, rear or seatpost also make a bike more expensive. With this optional approach, a rear wheel damping is sufficient. All child seats can also be fitted with these types of spring-loaded wheels. 




10.)  Thieves lock


With a long steel cable lock, which can be pulled out of the frame, the wheel can be attached and secured against theft. A second high-speed immobilizer would also be practical and practical.

The securing of steel cable lock, battery, storage basket and Solardach should be possible with only one key. Even better would be a handsenderschloss - which as in the case of cars for a long time usual - everything centrally locked.

Also existing app solutions are useful for finding a wheel again.



Delivery WHEEL - Storm firm


For a storm-safe, vertical parking, a fahrRAD-Cargo at the load bridge front and rear would each have a wide U-bracket stand.

In the Cargue area, three-wheel trailers with their own electric motor can be produced for heavy-load transports (see, for example, - the cover of which could also be fitted with a DC-supplying cover film.



Future of our bicycles


This fahrRAD would be an innovation wheel - not "just a nice weather bike" - and certainly popular on the market soon. The bike sector should be positively enriched by the increased safety and multi-range capability offered. As shown in Fig.

New ABS solutions and braking systems will also have a positive effect on the number of accidents by cycling in the future.


Our advantages today are:


#  A Cargo bike e.g. gives work to the deliverer and is useful against urban smog and traffic jams. 

#  These BIKE accessories would also contribute to further traffic and climate reassurance.

#  This fahrRAD would also be designed as Tandem, TAXI or family carriages. 




* The approach of placing the pedal axle in the front wheel has proven to be impractical.

**  see >

*** With an 18 "front wheel with high fork, the long lever arm finds place for good shiftability. 

**** PV films produce e.g. Alwitra-Evalon cSi ®, Hanergy ®, Nanosolar ® - oder Heliatek ®.

***** USB-Plog, Navi-Integration and a hands-free system, combined with the charging, mileage and speedometer display, in a foldable and removable display (in addition to a wide rear-view mirror) in the roof would also be good additional options.


Li / Io batteries already require the new EN 50604-1 standard! ,

A step description - from testing (ISO 4210) to sales and trading - is not part of this study.



It was also possible to realize locally adapted bike-productions from emerging countries! My Trethebelgear and other is in any case free of charge. A cost-effective alternative mobility, with the avoidance of fossil and road-building disadvantages, would certainly be welcomed.
