It seems that each large car manufacturer has a bicycle in their assortment to promote one of their models. Porche, Mercedes and Ferrari all have them. So why not an “Locost bicycle”. After a weekend grinding and welding i came with this.

Greets, Roy

and another pic.

brilliant!

space for an r1 in there?!

And the last one.

that is fantastic!

its really cool

What was the donor vehicle? I guess a RWD?



Looks great BTW, how does it ride?

Mike

Hey Guinness, the bike is riding really smoot. You feel like riding an motorcycle and you don’t have to put much force to the pedals to come forward rapidly. But the most fun thing is the response from people when they see you riding “That grazy machine”.

Greets, Roy.

Did you cut some bits off an old bike - eg pedal and steering bearings ?

Awesome effort! How do the brakes work? Rear hub brake?

Chris.

JonBowden: The only bits that where cut from an old bike. Are the pedal an steering bearings like you say, and the little brackets that holds the rearwheel.

Winston Todge: The rear wheel has an brakedrum and 3gear-hub.

The only things i had to buy where the special wide-flameprofile-tyres.
Here another photo when the frame work was half done.

greets, Roy

Thats really cool

Have you thought of writing a book with drawing plans and building tips

That does look very

...but....

One thing that would worry me is how the front forks are attached to the head via those two tiny tubes which must be under a huge amount of tortional stress. One bump could either make it a very "low" rider, or you could get speared by the pointy ends of the forks...

Probably just as well there's no brakes on the front...

you obviously had great fun making it but I not only worry about your steering head but also your section that holds the rear wheel is relying on the strength of the joints for rigidity and will fail under stress loadings , you need a straight run from where the rear wheel mounts to the main frame loop. remember triangles are stronger than other shapes.........

assuming the welds are good, and from a distance they look good. and assuming you used left over pipe and not some fancy bike frame tubing then short of an elephant riding that bike over woozels he'll never have any structural problems.

She's not heavy she's bicycle. Oh wait, she is heavy.

3 speed internal rear drum? where did you get that wheel?


[Edited on 26/9/05 by A3rd.Zero]

Is it a good old Sturmey Archer 3 speed hub? I would put some sort of idler/tensioner on the chain, it looks a bit long to be unsupported unless it's as tight as a bowstring.

Ahh - but can it be built and raced for £250 ???

you'd hope so, it's a bike ffs

can't wait till we next scrap some bikes at work. i'm gonna git me a chopper!

MikeRJ: Don’t worry about the two tiny tubes between the steering head and front forks. These are just like the rest of the frame made from heavy construction steel and no thinly toilet-steel( such as we here in the Netherlands frequently say). Those little tubes are round 25x3 mm and the big ones that holds the wheel are round 35x3.5 mm. But thanks for noticing.

Niceperson709: Building the bike was certainly great fun. And you’re right, triangles are stronger than other shapes. But the fun of building a bike is to break all the rules, and build it like it isn’t possible. This frame is more stiffer and stronger than the donnor bike i used. But just like MikeRJ thanks for noticing.

Peteff: Yesterday i looked at the wheel and it was indeed an Sturmey Archer 3 speed hub. Ten points for you my friend!!! The chain is a little bit long. But is not really as tight as you think it is.
