Naked velomobile.

Hoe hard would be making by own and adding eletrical assistance, perhaps adding fairing?

muito este sistema de trassão

It's a beautiful bike. Too bad you never got a chance to improve it.

Nice! Well done! Good looking model too!

No chain ! Amazing creative ideas !

Salam Mohsen, your 2-wheeled (RWS is different ball game that requires different set of motor skills...) If U change it to FWS, it will work in shaa Allah ;-) Bro. Danial

What is there no footage of riding it?

A door having multiple keys will throw the state machine off unless the keys communicate

Yes!! Simplicity!

I can't believe I haven't seen this before. I was literally cheering at my screen! In-hub gearing and a trapezoidal steering link! Are you still working on this? I have a design for a 3-point trapezoidal steering linkage that incorporates suspension, that I dreamed up many years ago but never did anything with.

What is the bgm? So unique!

I'd like to contact you regarding this bicycle design in particular. I've visited your website and can't find an email corresponding to you. I've seen your trikes, which look beautiful. I'm concerned about friction in your drivetrain, though, and was wondering if you're interested in discussing some of this idea in particular. Thanks. Matthew I will give you my email if/when I get a response, thank you!

How can I build a sun Gear like yours

One of the coolest designs... Too bad you can't buy it :p

Der Witz ist: Ja, es funktioniert scheinbar, zumindest für eine gewisse Zeit!! Und man kann das schon auch nachbauen und es würde sich auch eine Weile drehen, ABER.... das Ganze funktioniert eben nur eine Gewisse Zeit!! Der gute Herr hier hat offenbar noch nichts von magnetisch induzierten Wirbelströmen gehört, die Magneten werden dadurch auf Dauer immer schwächer! Wenn man die Magneten wieder auffrischen wollte, müsste man (auf Grund verschiedener Verluste) noch mehr Energie reinstecken, als man vorher raus bekommen hat (somit bleiben die bisher unwiederlegten, physikalischen Grundgesetze der Thermodynamik erhalten...). Das ganze wäre dann also nur so etwas wie ein extrem leistungsarmer, schwerer, großer und teurer Energiespeicher, der am Anfang die Vormagnetisierung der Magneten ausnutzen kann. Technisch also wenig sinnvoll, daher auch nicht gebräuchlich.

hi can your gear design be install on a wheelchair wheel

Hi where is the freewheel

A shallower rake angle on the rear steering wheel would help this. Otherwise a great design.

Where can you buy these bikes or are they custom made?

my fist thoughts [ without reading everyone else's] (b4 reading that it may not balance) was that your interesting/peculiar steering pivot, in those combined radii, was to make the steering wheel track off-centre to the side it is steering towards !! But it wasnt.. I noticed when trying to ride a normal bike backward, was that the problem was; to turn left, the steer wheel would track out from under centre of gravity, to the right side, contrabalancing = bad. Perhaps all you have to do is to make your steer wheel track off centre to the side your steering to!!??,, by re arranging your combined radii arms!!!?? Lemmie knO whatchi think

Nice concept, bug there is one thing i dont get. when you disengage the brake on the outside gear, the wheel and its fixed central gear become the élément with the more résistance, and nothing prevent the outside gear to run backward, leading to loss of speed, up to complete stop, unless you are one a steep climb and the bike Will go backward ! i'm very curious to know, thank for answer. is this a school work or personnal hobby ?

According to control theory, a bike with backwheel steering is theoretically extremely hard (if not impossible). That is because the pole is to the right of the zero of the transfer function of the bike, where the transfer function for a basic bike with backwheel steering is: G(s) = C*V*(s + V/a)/(s^2 - g/h), where C is a constant, V is the speed of the bike, a is the distance from the center of mass (CoM) to the back wheel, h is the height of CoM and g is the gravitational constant.

he needs 2 wheels on a chain driven live Axel in the front

You might want to contact me. I have an IHPVA article by Craig Cornelius. He did extensive reasearch into a RWS recumbent. His final bike, the "Vel-Aero" was very ridable. Also, there is another guy here on KZbin with a successfull RWS recumbent. You have great fabrications skills by the way. Your planetary setup is really interesting and novel.

Recumbent bike- rear wheel steering? it is crap! Whats the point of building something that is not useable? This is not a bike, so it can not steer. ITS BULLSHIT. Sorry I hate to waste my time watching baloney.

no brake?

how is the gearing set up ,l live in fla. but do a lot of long rides [key west to bar habour main ]for domestic violence awareness,and fund raising, next i would like to ride to west coast of USA ,for this cause, ,is it good on hills ,ps lm no spring chicken, cheers Alexander.

sucks its not ridable it looks so cool defs like the front wheel design

A friend of mine could ride a bike sitting on the handlebars and pedaling backwards...

With fiberglass enclosed cabin and electric assist, you have the perfect city vehicle.

A rear-streered 2 wheeler is NOT ridable.....never !!! Sorry for the nice work !!

How bout if you had the wheels all pointed in different directions to steer it in different ways.

maybe a video of someone ACTUALLY riding it would help convince us of its stability and reliability... I think you coul've done it it 18 months...

Весьма оригинальный лигерад! Хотелось бы увидеть его в движении! Браво!

True, Doc. My view also. But the key point is that the rider sits on the front part of the bike, driving the front wheel, with the steering head behind him -- and actually with the axis of steering running up behind his back and through his shoulders/upper back. An unusual centre-steer, with the pivot right at the back of the centre section, perhaps. Great bike though. The one in his vid is Mark 2. He sent me stills of his Mark 1. Slightly less easy ride, I believe. M2 is the real easy.

More than a year from this video and no road test.. So i think that it's not stable and drivable. What a shame! I like this configuration so much.. Brakes it's not a problem and a gear-pack into the hub with 11 speeds are available. An hydraulic fork on the rear would be easily mountable.. but.. if there isn't a road test of this prototype, probably, this project don't work.

Dennis Renner's beautiful creation is not really a true RWS set-up though. I'd class it more as 'Centre-Steer' (like a Python), just with the pivot slightly further rearwards than usual (for a Python).

Brakes?

We can have all the drama on the build, but the trick to to get a RWS ridable. This being 9 months ago, I assume it is not.

wow! how did u cut the saw wheel???

Dennis Renner has cracked the problem of a stable, practical, easy-ride FWDRWS. See his videos at recumbentartandpoems.

Hermosa !

innovative and very clean. curious about the stability and ease of correcting slow-speed imbalance. any video riding it?

I have such respect for your abilities. Why don't you try what I tried- make the rear wheel point at the point of contact of the front. This might require a (wobbly?) trapezium linkage but to my mind is the only way to get stability. Good luck. Mike.

Cool drive. Can you ride it yet? I tired building a rear wheel steer, front wheel drive recumbent 30 years ago, but I couldn't ride it.

absolutely brilliant!:D well-done mate;)

How is the ride?
