7.) 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!

8.) Tackling 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.

9.) 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.

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, www.carlacargo.de) - 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 - no "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.

* The approach of placing the pedal axle in the front wheel has proven to be impractical.
** 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.
To a further prototype I have so far lacked the necessary funds and a specialist company as a competent auxiliary.
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.
