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.

This  freely available suggestions to TOP-TEN 4Bikes  are particularly directed at the bicycle and parts manufacturers

 

 

  

1.) In the rest lies the power

 

A classic "upright bicycle" challenges us from a grueling, over-curved sitting and working posture; and recumbents position their driver just above the tarmac.

 

However, a slightly sloping backrest provides a comfortable and optimal supporting posture; It makes active walking more powerful, more efficient and keeps you relaxed.

 

When leaning against the seat, an anatomically supporting counter-support with ergonomically optimized pedaling is conveyed. It also makes cycling in this sitting position safer.

 

The saddle and the back rest are placed a few centimeters further back. The handles of the handlebars are to bring closer to the driver; Its location resembles that of an Easy Rider on a Harley.

 

Further advantages of comfortably ajar seating:  

* With the center of gravity displaced to the rear, you do not crash headlong over the handlebars in the event of an impact or fault braking.

* A safety belt adds real protection. The belt is e.g. anchored to the tubular frame of an expanded metal shell backrest.

* A so executed rest protects the head area, shoulders and hips in the best possible way and makes a helmet obsolete.

 

 

2.) Ow, my butt

 

Another innovation, also useful for conventional bicycles, is presented here:

  

Especially on longer trips conventional saddles are actually quite uncomfortable. However, a saddle can also form two elongated, good seat bidding buttocks, which are mounted side by side on an axle. These accomplish the bouncing pedaling motion of the driver. Such a "rocker saddle" increases - for ladies as well as for men - the seat comfort - by its noticeable relief in the sensitive crotch area.

 

 

 

3.) BIKE drive - seesaw instead of cranks

  

 

Instead of a rigid pedal crank set the following lever pair is used:

 

Both levers hold a crafted as a square freewheel. These levers are attached to the square pedal axis as usual on both sides and connected to this. Previously, the pedal axle 1 - 3 chainrings attached externally. Also, the lever ends - by means of a thin version of a wheel chain which is guided under the saddle on a corresponding gear -  as a rocker to connect.

 

3.a) The pedal-gearshift

 

For this circuit, the pedal axles are connected with sliding sliding sleeves, which have a limited margin along the lever arms.

Between lever arm and sliding sleeve leg relief, a coupling relief is formed from waves.

Two bow springs, which are embedded in the opposite leg side, press the selected gear on the clutch relief; This prevents unintentional shifting of the pedals.

 

To select the gear, the instep of the feet pushes laterally outward against the sliding sleeves - for this purpose there are outer short insteo-hooks on the pedals. In now free change an uncomplicated and direct gear selection is possible. 

The search for the desired transmission ratio is easy to practice and independent.

  

The advantages of this circuit are:

* The "rocker-lift" replaces any type of rear-wheel gearshift  and provides a full gearshift. The 3 (optional 5) gears selectable on the lever arm unfold in combination with the front chainrings an optimally spread overall ratio for both uphill and downhill driving.

* This device has only about 350 g total weight! It eliminates a number of items and cables of a rear derailleur or hub gearbox.

* This gearshift provides on demand a continuous direct and highly efficient pedaling with correspondingly higher tempo performance. Short rocking breaks are inserted at will.

* This Set is presumably inexpensive to produce. It still offers a simple interchangeability of a defective freewheel or pedal bearing.

*  Also interesting for unicycle upgrade / equipment.

* Retrofit kits would presumably also be a sales hit because they fit all standard-uniform bottom bracket axles.

 

 

4.) A bicycle - for two-forces

 

This tandem-single-version has a slightly stretched frame construction, to which a second leaning saddle can be put on.

The extended beyond the pedal point here lever arms are operated by the second driver via attachable pedals. The double-sided lever arms are therefore a fixed wheel inventory.

 

For single tours, the second pedals and the second saddle can simply stay at home.

In pair operation, a harmonious and perfect division of labor is possible with independent gear selection. 

This opens up the development and market consolidation to a creative lightweight Tandem-Single-Bicycle.

 

The outfit would remain the concrete design result of the respective bicycle manufacturer.

 

 

 

5.) In heat and rain

 

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

 

The fact is, our city, cargo and touring bicycles only offer high driving comfort every day if they protect us from wet or direct sunlight. An attachable protective roof would encourage you to leave the car more often in the garage. Maybe it can change some quite on a bike.

 

A horizontal weather protection roof protects against sun and rain. On the other hand, as a photovoltaic foil stretched on the aluminum roof frame or as a roller blind, it also supplies a considerable part of the drive energy.

The electricity generated on the roof is fed into the solar battery integrated in the fahrrad frame (in tube). The approx. 150W PV foil ** harvests daylight electricity all day long - even in diffuse weather conditions.

The approx. 1.1 m² roof generates roughly the energy of a medium-length driving route.

 

The lightweight, detachable roof is wind-slippery; because even changing winds are actually flat. In a longer test phase, I drove one without any problems - even with strong gusts of wind.

To retrofit such a roof - behind the saddle-backrest or on the handlebars clickable - always a win.

 

The four roof corners optionally contain the flashing lights of a turn signal. The lights fed by the battery should - due to the dangers in today's traffic density - be supplemented by a brake light. The reliable on / off switching of the night lighting should be done by a twilight sensor.

The ~ 60 x 180 cm large roof can be moved about 60 cm forward in the rain and ensures that everything stays dry. Frame and foil can roll and/or be constructed foldable.

A wind- and visibility-permeable net-store protects against rain as well as from strong lateral sun. If necessary, it is attached to the roof frame by means of Velcro. The store has a lead band at the lower hem and hangs sufficiently low with about 55 cm. 

 

Sporty cyclists might also like this top hatch without electric drive (covered with perlon instead of PV foil, weighs only about 700g) **.

  

 

6.) Hand saver

 

In order to avoid the usual microtrauma in the wrist, a cylindrical, elastomeric pipe plug connection could be embedded for impact mitigation in the steering handles or their transitions to the steering bracket. This stiff-elastic bridge could be different on the weight of a person or different, different deep let in.

 

 

7.) The little cargo

 

The area behind the sloping backrest provides space for luggage or even for one or two child seats.

Also conceivable would be a lightweight, removable and lockable expanded metal basket with hinged lid, which can be pushed after shopping like a travel case on four castors, with a light hand. This basket could also be made of woven wicker as a practical 4-wheel trolley.

The child seats would also be fastened with the same click fastener; they might have a pair of wheels located on both sides of the seat and a guide bracket which can be pulled out of the backrest. So the seat would after the trip to baby stroller.

 

 

8.) Airless tire?

 

My idea of a new type of tires made of harder rubber compound requires neither the usual rim bead wire nor fabric inserts, neither a hose nor internal air overpressure. These types of tires already spring through their thick-walled hard rubber cross-section profile (see drawing). In the case of higher loads, these tires can still inflate accordingly.

 

In addition, a small-finger, medium rolling bead offers the perfect minimized rolling resistance. The lateral, broad, optimized on Gripp broad auxiliary beads roll only in an inclined position in contact with the ground. Inflating and "patching pecking" are eliminated in this nock-resistant model.

For tire mounting, these fahrRAD tires have a two-piece "screw-on rim", which ensures a perfect and form-fitting tire seat.

And on top of that, the wire and fabric-free material is unproblematic in recycling and recyclable as granules! 

Especially on rough terrain and in the transport of these tires is durable and low-maintenance.

 

 

 

9.) Bothering a RAD was yesterday ...

 

Back-friendly side effect on the newly conceived fahrrad: the rear wheel can be optionally with 12 conical glass fiber bow springs or steel leaf springs instead of conventional spokes receive an effective shock absorption. After all, other popular shock absorbers for the front, rear or seat post make the price of a bicycle more expensive. With this approach, due to a given rear-wheel-centered center of gravity, damping is sufficient (even pushchairs can in principle be equipped with such wheels).

 

 

10.) Long finger lock

 

With a long steel cable lock that can be pulled out of the frame, the wheel can be attached and secured against theft. A second quick-immobilizer would be just as practical and practical.

Securing the steel cable lock, battery, storage basket and solar roof should be possible with just one key. Even better would be a remote control lock - which, as is the case with cars for a long time - locks everything centrally.

 

 

Conclusion: As an innovation bike, this bike would not be a "good-weather bike" and will soon be popular on the market. It should - thanks to the increased safety and multigrade capability - positively enrich the bicycle industry!

 

The general advantages are:

* A Cargorad e.g. gives the deliverer work and is useful against urban smog and traffic jams.

* These fahrrad additions would contribute to further traffic and climate comfort.

* This fahrRAD would also be constructible as a tandem, TAXI or family carriage.

 

Concrete frame designs result depending on the type of use and personal design creation of a fahrrad manufacturer.

 

Future of our bicycles

 

On the market available motion alarm u / od app solutions for Saving u / od again finding a wheel.

New ABS solutions and brake automata will positively influence the number of accidents on the bike in the future.

For storm-proof, vertical parking, a cargo bike has a wide U-bracket stand at the front and rear cargo racks.

In the cargo area, 3-wheel trailers with their own electric motor for heavy-duty transports can be produced (see, for example, carlacargo.de) and their cover can also be equipped with a DC-supplying film. Also ONOmotion.com offers new to Cargo.

 

 

* The approach of placing the pedal in the front wheel has proven to be impractical. For another prototype so far I lack the necessary funds and a specialist company.

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

*** USB plog, navigation integration and a speakerphone, combined with the charge, mileage and speedometer, in a folding and removable display (in addition to wide rearview mirror) in the roof, would also be good options.

 

 

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

Compare to the pedal lever drive >> www.freepatentsonline.com/DE4329814.html. ,

A step description - from testing (ISO 4210) to sales and distribution - 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.
