Not buffalo-drawn carts with heavy, large wooden wheels have China and India dragged into modernity, no, carrying the myriad loads of carrying bicycles
(and in part lead to today) this era.
fahrRAD-solar - Tandem - (Cargo >> 6.a)
These patent-free suggestions TOPten4Bikes are given especially to bicycle manufacturers and their suppliers.
1.) In the rest lies the power
A classic "upright wheel" challenges us from a grueling, over-curved sitting and working posture; and recumbents position their rider too close
to the tarmac.
However, a e.g. 60° sloping backrest provides a comfortable and optimal supporting posture; With it,
active pedaling becomes more powerful, more efficient and you stay relaxed. Leaned sitting conveys an anatomically supportive support with ergonomically
optimized pedaling. It also makes cycling in this sitting position safer.
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 a collision or faulty
* 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 best in an accident the head area, the shoulders and the hips and makes a helmet obsolete.
2.) Ow, my butt
Another innovation, which is also useful for conventional bicycles, is presented here:
Especially on longer trips conventional saddles are actually quite uncomfortable. A saddle can also be formed from 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 pair of levers is used:
Both levers have a free wheel around the square eye. The step levers are attached to the square pedal axle
on both sides, pointing in the direction of travel, and secured with them - as was previously the case with the conventional crank set - with screws. Before this, 3 external chainrings
are attached to the pedal axle (which are otherwise permanently connected to the right crank).
A short wheel chain connection attaches to the first third of the lever arms. The chain is deflected by a sprocket, which is located on
the seat tube above the bottom bracket and is covered by a chain guard.
The leg that is not working is also raised in the dynamic and thus passively brought into the readiness.
* A direct, highly efficient pedaling with correspondingly higher speed performance can be achieved with a step
* With previous cranks, 2/3 of the path is empty without propulsion. Here, on the other hand, only the working third is served.
* Standing quilting - using your own body weight - is also possible.
* Interim short rocking breaks are taken at will. The freedom from dead center allowes a free division of
This also inspired me to create a simple ...
3. a) Pedal gearshift
For this purpose, the pedals have a sliding sleeve which can be moved along the outer 2/3 of the lever arm. There is a wave relief
coupling between the lever arm and sliding sleeve. Due to the arch springs installed opposite it, a selected gear is pressed onto the clutch relief and prevents the
pedals from being moved unintentionally.
When choosing a gear, the instep of the feet presses outwards - there are short instep hooks on the pedals. In the now free change, an
uncomplicated and direct gear selection is possible.
Finding the desired translation ratio is easy to practice and become independent.
The advantages of this circuit are:
* The pedal-circuit can also be selected on normal bicycles - instead of
* The "rocker arm" becomes a full gear shift. In combination with the three front chainrings,
the 5 selectable gears on the lever arm unfold an optimally spread overall ratio for uphill and downhill driving.
* This device has only about 350 g total weight. It eliminates several items and cables of a rear derailleur or hub gearbox.
* It offers simple direct selection for a coherent gear ratio.
* This gearshift provides on demand a continuous direct and highly efficient pedaling with correspondingly higher tempo performance. Short
rocking breaks are inserted at will. Standing stepping using your own body weight is also possible.
* It also offers the interchangeability of a defective freewheel or pedal axle bearing.
* Also interesting for unicycle upgrade / equipment.
* Retrofit kits would probably be a hit, as they fit all standard 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. These 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-bike!
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 some people change to a bike.
A horizontal weather protection roof protects against the 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 bike frame (InTube). The approx. 150 / W PV foil *
harvests daylight electricity all day long, even in diffuse weather conditions.
The approximately 1.1 m² roof generates about the energy of a medium-long driving distance.
The lightweight, removable roof is wind-slippery; because even changing winds are actually flat. In a longer test phase, I drove such a problem -
even with strong gusts of wind.
For retrofitting such a roof - behind the saddle-backrest or on the handlebars clickable - always a profit.
The four roof corners optionally contain the flashing lights of a turn signal. The lights supplied 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.
A wind- and visibility-permeable net-store protects against rain as well as from strong lateral sun. If necessary, it is fastened to the roof frame
by means of Velcro. The store has a lead band at the lower hem and hangs sufficiently low at about 55 cm. Frame and foil can roll u./od. be constructed foldable.
Sporty cyclists might also like this top hatch without electric drive (covered with Perlon fabric instead of PV foil, it only weighs about 700g)
6.) The small 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 plaited willow as a practical 4-wheel trolley.
The child seats would be attached with the same click fastener; they might have a pair of wheels located on both sides of the seat and a guide
handle which can be pulled out of the backrest. So the seat would a buggy after the ride to the children.
On the steering shaft is e.g. the KLICKfix carrier is ideal - luggage stays centered on it.
6.a) fahrRad or e-bike with a heavy-duty trailer
This is a low loader trailer which is steered via the bike or fahrRAD. It provides CO²-free delivery services, possibly also taxi
services, and is especially designed for today's climate.
This 2.9 m long trailer travels on a 125 cm wide track and weighs approx. 115 kg, witha load of 800 kg.
Right behind the drawbar, which can be raised, two 35 cm large twin wheels – with their turntable base to the load space – take some load off
the bike - fahrRAD.
The freight weight is distributed over eight wheels including two 60 cm twin rear wheels.
Four synchronous recuperation hub drives take over the idle as well as the load operation. Their performance would be limited to a max. designed
to move a load of 900 kg. The energy recovered from the movement is optimally kept in high-performance storage capacitor banks for subsequent start-up - that are still to be
developed (possibly with Zehus).
The e-motors should have a 3 km / h slow return gear and a 5 km / h first gear for solo tiller hand guidance.
The four recuperation-synchronous rim brakes allow driving at 25 km / h at full load and up to 45 km / h at idle or part load.
Instead of a rear-view mirror, the trailer has a rear camera; this shows the driver what is going on behind.
The extra deep and 3.6 m² large loading area consists of 16 mm plywood. The spring suspension takes place via 10 compression springs that
connect the frame to the loading area.
With a track width of 125 cm, the 170 cm high body withstands lateral wind. The side tarpaulins remain rolled up in strong winds and low freight
weight. The structure offers space for 3 pallets of goods on a 6 m³ loading space.
The trailer is bridged in a U shape with the 1.7 m high roof frame made of large-mesh welded mesh. Everything is covered with a solar fabric
film (e.g. made by manufacturers Alwitra or Heliotek). The cargo is also protected from the side by tarpaulins. They are opened or closed by means of special
e-roller blinds and at the same time they pull the zip fastener on the sides. In addition, the load is secured with tension belts. This covering provides sufficient energy via
its 12 m² photovoltaic surface - even when it is cloudy.
Batteries are accommodated in the chassis of the trailer for long transport routes; they are inserted into their own subjects there. These
batteries provide sufficient travel reserves and are recharged with a cable.
6.b) The trailer can also be converted into a family carriage or
comfortable camping tent::
The carriage (or the taxi) has up to 4 plug-in seats for passengers - 2 to 3 people each. They are made of felt-covered, light plywood seats on
a metal frame. With three rows of seats, the trailer still has space for 1 or 2 pushchairs. You can enter from both sides; there is a 1 x 0.6 m window on the front and rear;
The PV tarpaulins on the side also provide an all-round view for a maximum of 12 people during a journey thanks to integrated windows made of film.
On cold days, gentle quartz heaters provide warmth for the passengers.
The attachable side folding walls made of light multi-wall sheets result in a 12.4 m² living / sleeping level for when in tent mode. When the
walls are opened, the tent opens, with four arching clips opening at the same time. Then adjust the four corner supports - done!
Now everywhere is a nice camping lot or a free parking space! With its own electricity, solar ink and of course with an organic composting
toilet, the wide world can now be traveled even on a budget.
Every e-bike can be coupled up to this trailer. Either as a trailer, or as a carriage for the whole family or for
urban or rural delivery services and taxis - this "packhorse" facilitates emission-free transport services based
7.) 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. The extra-deep loading area and large disc brakes allow a top speed of 25 km/ h.
In addition, a small-finger, medium rolling bead offers the perfect minimized rolling resistance. The sideways, wide, on Gripp optimized, wide
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 bike 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 when transporting loads, these tires are durable and require little repair.
8.) Hand guards
In order to avoid common microtraumas in the wrist, a cylindrical, elastomeric pipe plug connection could be embedded in the steering handles or their transitions
to the steering bracket in order to mitigate impacts. This stiff-elastic bridge could be available differently depending on the weight of a person or recessed differently deep.
9.) Laboriously storing a RAD was yesterday ...
Back-friendly side effect of the newly conceived bicycle: the rear wheel can optionally be given an effective shock absorption with 12 conical fiberglass arch
springs or steel leaf springs instead of conventional spokes. Because other common shock absorbers for the front, rear or on the seat post make a bike more expensive. With this approach, due to
the given center of gravity close to the rear wheel, damping is sufficient (prams can also be equipped with such wheels in principle).
10.) Long finger lock
With a long steel cable lock that can be pulled out of the frame, the bike can be attached and secured against theft. A second quick immobilizer would be just as
practical and practical.
It should be possible to secure the steel cable lock, battery, storage basket and solar roof with just one key. It would be even better to have a handheld
transmitter lock - which, as is the case with cars for a long time, locks everything centrally.
Conclusion: As an innovation bike, this fahrRAD would not be "just a good weather bike" and would soon be popular on the market. It should -
through the increased security and multi-range capability - enrich the bicycle industry positively! The innovations can be used individually.
The general advantages are:
* A cargo bike e.g. gives the deliverer work and is useful against urban smog and traffic jams.
* These fahrRAD additions would help to further reduce traffic and climate.
* This bicycle could also be constructed as a tandem, TAXI or family carriage.
Concrete frame designs arise depending on the type of use and personal design creation by a fahrRAD manufacturer.
* Create PV films e.g. Alwitra-Evalon cSi ®, Hanergy ®, Nanosolar ® - or Heliatek ®.
** USB plog, navigation system integration and a hands-free system, combined with the charge level, 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 trade - is not part of this study.
With my innovative approaches you have a market advantage for your bicycle
This will prevent you from leading another manufacturer.
I can offer additional solutions to detailed questions for startups who want to implement this.
Locally adapted fahrRAD productions could also be realized by emerging countries! In any case, all 10 innovations
are available free of charge. A cheap alternative mobility, with the avoidance of fossil and road construction disadvantages, would certainly be
welcomed and necessary there.
