Looks cool but with a rake like that I wonder what its going to steer like, hope not like easy rider Harley.
Thank you for your interest RIPPERTON, but I'm thinking the rake and steering in general will be....different, more on that soon!!Looks cool but with a rake like that I wonder what its going to steer like, hope not like easy rider Harley.
Thank you for your interest Duncan! you are right, I wasn't thinking on regular forks and simple steering, partly because of what you say, and partly because I have my sights on something completely different. The Hub centered steering has always been a fascination for me, but strikes me as extremely complex for implementation without professional equipment, hence I'm exploring something new. A lot of advantages? interesting! care to elaborate?Hi
With that layout a bike type of telescopic forks and simple steering won't cut it
You will need something more like a car steering system - still with the handlebars
Look up "Hub centered steering" or "Quasar"
If you use a decent type of front suspension and steering that type of bike has a lot of advantages over the normal head first system
Thank you Duncan. You think? maybe I'm seeing a mountain where there isn't, do you know where I could find building information?Hi Bruce
Look forwards to seeing what you come up with although hub center steering is really not very complex
One thing - contrary to popular belief a lower center of mass in a bike makes it more difficult to balance - not less
To illustrate that point take a 12 inch ruler and balance it on end on your hand then repeat for a 3ft ruler - the longer ruler is much easier to balance
thank you for your help Ken!A couple of points to consider:
Recumbent bikes are very difficult to balance at low speed! ( a trike is much better) Although a bike this futurist looking probably has a gyro-stabilizer.
It's your bike...You can use any size tires you want! I did.
Hi Duncan, thank you for the quick response.I expect the Mark 2 to be unlike any motorcycle riding experience so far, never ridden a recumbent so I'm hot on that trail.Hi Bruce
More difficult to balance does not mean impossible
Just don't expect it to be easier!
I have ridden a recumbent two wheeler of a few thousand miles - it's great fun!
Hub center steering
You need a front swinging arm - with suspension - that curls out to allow the wheel to steer then curls back into the center of the wheel
Actually much easier than making your own telescopic shock system would be and you lose most of the sliding friction problems
Car bits will be too heavy for this but racing rose-joints would be ideal
The only "secret" is to have the steering axis (the line the wheel turns around) on the center-line of the rim
Hi Duncan, the steering mechanism moves the tire on a pivot point, and also the swingarm and it is connected to the chassis byt 1 point of rotation, it's actually quite smooth to ride. Check the videos on the Travertson V-Rex, they are cool.Hi Bruce
That looks like the whole thing steers
I predict that it will feel bloody awful! - OK to look at but not usable on the road
You need to look at the tire contact point - and the point on the road that the tire rotates around
Optimally the two are quite close together with the rotation point just a wee bit in front of the tire contact point
Hi Piotrsko! thank you for your interest2 comments: I would have liked to see the original wheel profile in the drawing to compare to the photoshop picture.
Are you aware of the tricycle effect lately in Harley wide glides with what looks to be about a 26 rim and 3.5 tire and wheel combo? Since it is harley, should be good for front or rear and it looks to be about 31" diameter.
