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. 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
Both levers hold a crafted as a square
freewheel. These levers are
attached, pointing in the direction of travel, 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
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
The search for the desired transmission ratio is easy to practice and
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
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
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
The outfit would remain the concrete design result of the respective
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 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
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.
