Default Hub steering concept bike

here are the pics of the bike ,i helped design and build,for engineering students from chennai.It is hub steered bike like in cars.It almost eliminates diving when using the front brakes.There are lots of concept bike from bimota

too bad this thread wasnt checked out by anyone. I think your work is beyond words of anyone in this forum. Venu, How feasible is this on a Enfield bullet? Please let me know? and how stiff is the steering linkages? Are these made from Car parts?

Main point - Overall cost please???

Yes you're right. Aprilia i think also has a production bike with a similar non fork front suspension setup that sells for upwards of 30000 USD. There've been several experiments by many european and japanese manufacturers. Btw this is a great project too. It'd be great if you post more about how the bike feels in comparison to a stock yezdi!

Can you please explain us how does it reduce nose diving. I am not able to figure it out as still suspension is there for the front wheel.

Also, how can one adjust caster angle (is there one?) on this kind of setup?

Wow ! This is really cool work

So in a system like this how would one define the traditional bike steering parameters like rake ?

Could we have some pictures from the front also ? How does the front wheel rotate since it seems to be on a solid axle & secured from both ends ? Did you use the spindle of a regular car ?

What would your advise be to somebody wishing to try out a concept like this - trial & error, paper, or 3D CAD like SolidWorks ?

The Bimota Tesi series of bikes use such a setup. One of the Italijet scooters also uses such a setup.

Commendable effort! An explanation of how it works and a review of how the bike actually handles would be interesting.

What, for example, is the experience of making a U-turn? A picture of the handle at full lock at either end may help us understand how steering is accomplished.

The System actually offers advnatages in situations when one has to brake and steer at the the same time, not something which one would like to do on bikes with conventional suspension. Here one has to understand that during braking the weight transfer causes the front suspension to compress however with this system since the supension is horizontal so even during braking the shocks are not compressed and are only compressed due to undulations on the road which is what actually should happen ideally. Moreover since the system uses one spring instead of two telescopic forks one is saved the trouble of synchronizing the two forks, altough I am not completely sure about this bit.

I'm speechless. This yezdi modded so neatly and the engineering behind it is awesome.
I am proud to be a member among you.
