Motorcycle Roof Rack

[einsign]

Does something like this actually exist, if not why not?

[einsign]

I am very serious, specifically for off-road bikes up to around 120kg.

How do you plan to get it on and off the roof?

Via a winch mechanism and extendable track system.

Have you given this a moments thought?

At least one moment or I wouldn't have posted it on here

trying re-reading the comments made so far and giving it another moments thought.

Not one of the comments above gives any reasons or detail as to why it cannot be done?

you are a fking moron

Thanks, do you know who I am or what I do?

Maybe for safety reasons alone no one has designed anything like this.

You could well be correct but it doesn't stop us talking about it as a concept. You might also be surprised at the things people think cannot be done but with passion and determination eventually can be.

On another note, I wonder how many times the phrase was uttered "that will never work, only birds were meant to fly", or "don't be stupid, there is no way man can land on the moon".

I believe Mr Snap supports the green party, who would ban all motorcycles and re-seed the roads if he had his way.

For most cars, the weight would exceed the roof load limit. You won't find many family sized cars with a roof load limit greater than about 75-80kg, so even a lightweight trials bike would exceed the limit.

And given the implications on aerodynamics and loading, when there are better, and easier alternatives, everyone is correct in saying.........it's a fking stupid idea

It boils down to knowing certain data before you can just say no:

1/ The torsional strength and shear loadings at the point of connection to the roof (depending on vehicle and method of connection)

2/ Most roof racks are crap and their maximum load is relevant to the racks strength, it has nothing to do with the load capacity of the vehicles roof connection points.

3/ Not even worth discussing for anything smaller than a medium/large size car.

4/ Aerodynamic and weight distribution issues, ie forces at connection points when turning etc.

5/ PH'er opinions.

Doing what, roofrack engineer?

Mr2Mike said:

Irrelevant. The car manufacturer will give a maximum roof load which is independent of any roof rack limitation, and around 75kg is a common figure.

Can you show me the data, or did you just make up the 75kg figure?

Tell you what. You fk off, find the supporting info and prove us wrong ok?
Until then, either do a mechnical engineering degree or fk off. Really.

Are you an angry shouty person in the real world or just on the internet?

Have I asked for your opinion or do you have nothing better to do?

[einsign]

Sheep.

ignorant obtuse in the real world

I am probably just as bad in the real world, which who knows by ignoring people like you could be why I am pretty successful at what I do.

which isn't designing roof mounted motorcycle carriers one would presume.

Correct, but after all of the positive encouragement I have received here I have now applied to appear on Dragons Den.

[einsign]

3 Sheep could easily weigh over 200kg, and on top of a small car. I am even more determined now that such quality data has been supplied!

Make sure you take this

Will it fit on a roof rack?
