New GENUS ...of Bicycle... Can you make this Sunnycle
Postby sunny_fruit » Mon Feb 14, 2011 12:35 am
Today I made pictures(drawings) of this bike
and because I am unable to do it ... for now
... now, I post photos on the internet
... and looks forward to seeing who will do it first
...... if you're handy,
...Do it
It is:
A new type of propulsion (lever)
A new type of control (saddle-back)
- lighter
- faster
- comfortable
- Can be folded
- Front wheel drive
- With an excellent aero-dynamic
- Simply arranged and therefore cheaper
- The pedals move reciprocating - and not circular
- The pedals move independently of one another
- multi - speed lever drive system
- Free - Hands bicycle
- Turbo Mode

Chain and pedal is way more efficient than the lever system and rear wheel steering except in one or two specific instances has been a failure. Don't believe me. Try driving a rear steer forklift at any speed.
Good to see people experimenting but it is probably better to design around what has been proven to work.

Yes ... now I know what you think and what are your worries
?? ... Rear-Wheel-Steering RWS
Ordinary road bike has some shortcomings that do not like ... they are:
... Not better aerodynamics
... non-comfortable seat
... inability to use the full force of the cyclist
These flaws are gone in this new species bicycle
... but the price is - RWS
... all say that this species bikes are awkward to manage ... and I knew about this flaw ...
what are the reasons RWS is unstable and difficult to manage:
... RWS - tadpole
... long-wheelbase (distance between the two big wheels)
... high center of gravity of the driver
... smaller wheels
It is a compromise between these three conditions:
.. the least possible distance between the wheels (- the radius)
... the lowest possible position of the cyclist (height diameter)
.. possible large wheels (32 "- 37")
So this is the result ...
... and since no one has ever proven ... and do not share the experience of using this type of bike (with those dimensions and proportions) ... and in my search on the internet, I saw nothing like this bike
... and so I will not draw your attention to your comments .. and I will use RWS

1) Ideas and inventions come with out of the box thinking, and is often a gift.
2) There are way way more "inventions" than what's really practical in real life.
3) Making an invention work requires common sense.
4) Publication of this idea in an open forum has just turned it into public domain, and no longer patentable.
5) Without a patent, there'll be few financial backers willing to get involved.
6) Without financial backers, the project will likely stay to be a hack project and stay that way.

The reason they are unstable is that the centrifugal forces acting on the centre of mass in a turn tend to force a RWS vehicle into ever-tighter circles of oversteer.Sunny Froot Loop wrote:what are the reasons RWS is unstable and difficult to manage:
Front-wheel steer vehicles are dynamically stable as the centrifugal forces acting on the centre of mass tend to force the vehicle straight... unless you lose grip at the rear.
Losing grip at the rear (oversteer), a situation analogous to rear wheel steer, is far more difficult to recover from than understeer and usually requires very quick reflexes to successfully control. Let it get past a certain point, and it doesn't matter how good you are, you've lost control.
Given that you don't have the front wheel steering on your vehicle to enable recovery, your bicycle design is dangerous and a potential fatality waiting to happen. Do not build it. Any second year automotive engineering student would be able tell you this.

There are lots of "Sunny"s out there. Usually thinking they have a "new" idea, then rush to tell everyone about it without bothering to do basic research first, build a prototype or protect their intellectual property.
Anyone can post a few drawings on line and ask someone else to do the real work of making it work. IMHO, it's just another form of trolling.

Personally i think sunny is showing some good thinking, just needs to look into the realities of the interaction between human and machine. A simpler form of recumbent is a good thing i feel (looking at making my own and baulking a bit at the long and convoluted chainline).

Don't know if I would want to ride one of these though. Not in traffic. Maybe in the circus where I normally ride this sort of bike.
I love your lateral thinking - Keep up the good work. Wayne

There's another thread here about another similar idea.
We shouldn't be too down on new ideas but there is a history of re-invention in bike design, we should all be aware of the history.

A the alternative that presented earlier .... just unfortunate history
explanation is ... joint between the two parts of the bicycle frame is a little more specific ... when cornering, the front wheel tilt ... so both tires move after another ...
... This makes STABLE AND PRACTICAL ...
