Motorised cycle discussion!

Ryan Jones

Forget everything about how much your contraption weighs and the braking forces as a result of it. When braking your brakes effectively remove the kinetic energy you have as a moving object in order to stop you, and theres a rather simple equation for that my friend.....

Kinetic Energy = 1/2 mass x Velocity squared

so lets assume it travels at 15km/h then....

1/2 x 200kg X 4.16 metre's per second (15km/h) squared = 1.73 KJ

In perspective Mr Weekend warrior on a 13kg bike weighing about 80kg's doing 20mph ie 32km/h

1/2 x 93 x 10 squared = 4.65KJ


Ohh wait a second, that means Mr weekend warrior will be stopping not far off 3 TIMES as much force with his brakes than you will be, and he'll be doing that constantly relying on his brakes to prevent a major accident ! This is also why getting hit at 30mph by a car is nowhere near as likely to kill as at 40mph, remember the creepy adverts with that little girl people in the UK ? (and no, not one in a bike trailer !)

But aren't you an engineer of legendary quality and skills, who is in possesion of a 5-axis CNC milling machine? If you were, you would be able to MAKE such a brake lever.

Am I to believe you lied to me?
My hero has let me down

Yes sheepsteeth,

A member on this forum most certainly did make an inference about my character that caused me a great deal of distress.
Call me what you will , but that particular member on this form was inferring that i am a person who engages in utterly repugnant activity, furthermore activity i personally find utterly repugnant, is greatly distressing.

This member expressed views that simply cannot be undone; views that even if retracted by an apology cannot reverse the ugly smear brought to bear on my character; views that have caused me a tremendous amount of distress.

From this point forwards, the situation has changed.

Fabian...lets be honest. We're friends now.


You're a bit of a mongo aren't you

Kaise

you are about as likely to get an apology from me as you are to get your bike to a speed above 5mph. I Stand by what i said, you mess with children, reference it all you like;

I'll infer some other things about your character if you like;

You have a Case of the Mark Fowlers (aka Bad AIDS)
You are Gay for Boys
You Like Children
You groom minors

Some of those things repugnant enough for you?


Welcome to the crudcatcher, if you ask a question we will help you but if you disagree and reply in such an odd fashion then i am afraid that you will get a "repugnant" response.

ah, ok..didn't know that. couldn't be arsed to read it from the beginning

Fabian2

What is more concerning than your public statements about my character, are your secondary comments, endorsing and reaffirming your original view.
Following on, you have then further added character damage to my name by disparaging comments; using the tag of homosexuality (so as to be of a damaging statement) , and a most abominable comment (in reference to your post) that i "groom minors".

Instead of spending time reflecting on your words and offering an sincere apology, the opposite has taken place, confirming your personal attack on my character, with additional material grafted onto the back of original comments.

Kaise

Whats your point?

EDIT: You forgot to mention that i said you had a case of the Mark Fowlers

Yep, thats about the long and the short of it. Well done, have a lime.

Also, after this thread, there is nothing left of your character to damage...

Just to prove it, I borrowed my mum's pedometer and pointed it at this thread and it went up by 2.

Hey, hang on, 2? Who's the other one?

Hang on, you pointed a step counter at the thread? :shock: Well, nobody's walking here, we're all on motorised-motorbike-bicycles.

What's Good AIDS? Aids like Cartman had in South Park?

There are no good AIDS, just goot aides.
There are AIDS and BAD AIDS, just like thee's a crash, and a BAD crash!

If I wanted to die, AIDS might be quite good, no?

Nah, this guy's motorised machine would be a better bet.

Kaise

i concur, although i fear this conversation may be considered to be a further repugnant inferance on his cood character

d!ck

i also heard that his mum takes it quite openly up the tradesmans entrance

Anonymous

I still want to know why such a legendary engineer, and my new Hero, cannot create his own braking system.

projectsome

Fabian perhaps you should just forget the brakes and or whatever it is the hell you're on about and use a tesco shopping trolley to push junk around. It's cost effective and good for the environment.

Well, it would certainly be a good aid to curing worms.
