available suggestions to TOP-TEN 4Bikes
are particularly directed at the bicycle and parts
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. A saddle can also form two elongated, good seat bidding buttocks, which are mounted side by side on an axle. These carry out the
rocking pedaling movement of the driver. Such a "rocking saddle" increases - for ladies as well as for men - the seat comfort - by its noticeable relief in the sensitive crotch
3.) BIKE drive - seesaw instead of cranks
Each bike pedal can be fitted with a rocker arm drive - combined with a 6 pcs.
Instead of a pedal crank set, the following lever pair is
Each lever has a freewheel in its square eye and is attached to the pedal as usual and
bolted to the axle.
Beforehand, the external chainring (optionally three chainrings) is to be
mounted in a form-fitting manner on the tread axis
The ends of the levers are connected to each other by cable and pulley under the
Each lever arm carries a sliding sleeve. This sleeve, which can be moved along the
lever arm, in turn carries the pedals.
Between lever arm and sliding sleeve a coupling relief of waves, teeth or rubber
coating is formed.
Against unintentional displacement of the pedals, a bow spring located between the
lever and the sleeve presses the selected gear on the clutch relief.
To select the footstool presses the sliding sleeves - by disk at the pedal end -
The now freely selectable caAgainst unintentional displacement of the pedals, a bow
spring located between the lever arm and the sleeve presses the selected gear on the clutch relief.tch the gear change is made in an uncomplicated, direct process.
The search for the desired transmission ratio is easy to practice and physically well
The advantages of this circuit are:
* The "rocker lever" replaces any rear-wheel gearshift and is sufficient as a complete
* The ability to combine with a 3-chain chain circuit,
however, remains; she continues to perform her wide gear gradation.
* With 5-7 accommodated aisles (optionally three times), this circuit unfolds an optimally spread overall ratio for
mountain as well as downhill.
* This device has only about 350 g sliding sleeve weight, and quite a few items and
cables are unnecessary.
* This gearshift provides on-demand continuous, high-efficiency pedaling and higher
* Short rocking breaks are inserted at will.
* The whole thing is inexpensive to produce and provides an easy replacement of a
defective freewheel or pedal bearing if required. Retrofit kits would probably be a sales hit, as they fit standard, standard bottom bracket axles.
4.) A bicycle - for two-forces
An extended lever arm beyond the pedal point of view, optionally results in an extended
pedaling mechanism for a second driver.
The only slightly stretched bicycle frame, if necessary, a second Anlehnesattel, and a
second pair of sliding sleeves with their pedals clicked (the handles are embedded in the tubular frame of the front backrest). These essays can easily stay at home on single
In couple mode, the RADfahr partner only competes with the same leg rhythm - and every
ride becomes a harmonious and perfect division of labor. Both have their free gear selection.
This opens up the development and market endurance with a new, creative
lightweight Tandem-fahrrad! The frame is then the concrete result of the respective design creation of a 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
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 Kinderwagerl.
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
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!
