Dirt bike tower thingy

[bogan]

I realize there are forces at play...
I couldn't design them all out...
If yer look at it you will see the up/down pivot point of the front axle
& tie down lower mounts are in line.. to stop the tie downs wanting to change
length / forks compressing , exspanding as the bike moves up/down

It would be possable to make the bike lean into the corners...
muliply the body roll of the car in the oppisite direction..
But really how complex do yer go ?

Interesting invention you got there!

I reckon a bike designed for all the knarl of off road and hill traversing lateral forces and the like, will have no issues holding itself together through the rigors of a Hyundai Lantra's cornering ability

Was just thinking if tyre wear did become an issue, you could get a rim and just swap it out for travel, I mean you have to unclip the chain anyway...

if ya had to go to all that bother a trailer would be a hell of a lot easier.

So would a van, but there's a lot of enjoyment in the doing of such things.

Building traliers is fun too, have built two bike trailers myself... a while ago now tho.

OP - you might want to blur your numberplate - some scrotes trace plates back to houses and nick bikes

And yes I know that the bike is in a lockup - just sayin'


Nicely made unit by the look of things, easier on the towbar than the "across the back" type.

My concern with this is there is no pivot point for the back of the bike. Yes there is the head bearings but that is at an angle.

Now that could be a problem.

Crazy suggestion I know, but have you considered of them there 4 wheeled vehicles with a big flat area on the back? No trailer required?

It would be if the forks were locked ridged... but they can pivot foward & arft
at the axle.. yer can pick the rear of the bike up it will pivot at a line though
the axle..tie downs fix on the same line so they can pivot aswell..
in fact what it dose do is give a castering effect... the bike always wants
to be directly in line with the car.. dueing most normal driveing the rear wheel will
only ever be a few degrees off straight in line with the car...
I have done tight 180* turns around the storage units where it's kept.. no issues.


anyways time will tell... I will know on sunday as I maybe useing it...

I'm more interested in the two-tone seat. Who sells those?

Interesting I'm living in the states at the moment and you can buy this very idea of the shelf.

Tow bars here are all the square box insert type so easily removed you can also get the more common rack that has the bike across the vehicle as a double cheap too.

I didn't realise that. Should all work ok then, will the back of the bike jump around (off the ground) a bit?
Looks well made good on you, have you tried it with a passenger lol.
