Introduction: Crush All Those Who Stand Before You, the Environmentally Friendly Way.

Park Tool Bike Month

Second Prize in the
Park Tool Bike Month



Convert your bicycle into an object of desire that makes even the hardiest mountain bike look like a little girl's cycle by comparison.



Step 1: Parts + Tools Needed... and Step 1.

Your bicycle.
A fat wheel from a trailer or van car.
Some bits of metal tubing.

A hacksaw.
A Welder,(I used an arc welder.)

Bicycle spanners and allen keys.

I have not gone into details such as how to remove forks etc., as these are found on any bike site and possibly even this site.


Step 1.

Saw fork legs off, near the crown.

Step 2: Step 2.

Saw a wheel off a vehicle or trailer.

This one was solid steel but only took about five minutes sawing.

Step 3: Step 3.

Weld forks to square section tubing in this configuration.

Step 4: Step 4.

Weld on a diagonal, for peace of mind.

Step 5: Step 5.

Weld the axle to the new fork. (baby's arm optional)

I can't believe this worked and remained strong using a little arc welder but it has.

Step 6: Step 6.

Re-attach forks to bike + brakes etc. (Back brake only)

Step 7: Step 7.

Now get out and ride it, its particularly fun in the snow, because of the lovely sound it makes.


I've ridden to work on it, hills and all, its very stable.
If you have gears it will be very easy to get a very scary speed up.
Don't make one unless you will enjoy strangers coming up
to you to discuss it and have a ride.



Anyhoo, Enjoy,

FriendOfHumanity.

Sweet!!!!!!!!! nice!!!!!!!!!!! I will give it 5 stars

I have just one problem, and I don't mean to sound like the nerdy kid who's afraid of falling down. This had to have added at least fifty pounds to the weight of the bike. Now you've gone and taken the brakes off the front, where they do the most good, and left only the back brakes which do a marginal job of stopping the bicycle at its stock weight, especially down hills. Have you thought about leaving the car's hydraulic brakes inside and possibly adding the brake lever from a motorcycle? You'd have excellent stopping power, although it would be weighed down a bit more. I love the bike, though, it's very Mad Max. If I had a welder, I'd build the same thing.

The brakes in the front of a bike do not do the most good, usually because if you don't use the back brakes, you will flip over your handlebars.

Using back brakes alone does you no good either. You need both. Without back, you flip. Without front, you can't stop well. Think before you speak.

You're silly. You won't flip if you only use the front brakes. I ride a motorcycle to work every day and a bicycle at least three times a week. A motorcycle brake system is set up similar to a bicycle's. The front and back operate separately, at least. That's possibly the only similarity between my two machines. Anyway, I rarely use the back brake on either and I've never flipped either, even when I mash down as hard as possible because some jerk cut in front of me and I don't want to end up as a part of someone's trunk. I've never even so much as lifted the rear wheel off the ground. However, I've used the back brake alone many times and what happens most often is that the rear wheel locks up and skids. Skidding seriously increases your braking distance and decreases your braking capability. The reason for this is because when you brake, the weight on the vehicle shifts forwards. Therefore, you have more weight on the front wheel and less on the back. The front wheel then has more traction because of the force pressed on it and the rear wheel has barely any because much of the weight is lifted on it. It's true. Google it. Better yet, try it. I find your statement "think before you speak" mildly offensive. Maybe I'm just sunburnt and cranky. Maybe I should just come back with a clever line like 'do before you speak'. Maybe not. Have a good one.

Yes , if you use both brakes, you won't flip. But, if you just use the front, it is very possible, especially if your bike is light in the back and not in the front. A motorcycle would not flip with just the front brakes because it has enough weight to hold it down. Anyway, with my particular bike, when I'm going about 10m/h, and just use the front brakes, yes, I stop, but the back wheel goes about a foot in the air. Anyway, i was just trying to make a point.

my bike flips sooo easily imthinkin of puttin a 50 pound weight on the back tokeep itfrom flipping my spacebaris retardedsodont annoyme aboutlack ofspaces

i dunno, i suppose that's possible. i've ridden mine down a hill much faster than that and jammed the brakes on. i guess it could happen if your arms happened to be limp at the time and you shifted your weight forward at the same moment as you braked it might happen. i believe that once you bring front suspension into the mix, the possibility for a flip may increase. depending on the types of brakes you have, possibly center pull brakes squeeze harder than side pull. ok. jamming on the front brakes as hard as possible going down a hill on a mountain bike will probably send you flying over the handlebars. but i still don't believe that jamming on both brakes as hard as possible going down a hill on a mountain bike will make you less likely to flip. i suppose using less force on the front and little on the back would be better. i ride a road bike and rarely use the back brake anyway. even at speeds above thirty miles an hour going downhill and i've never had an issue with liftage. i've never ridden a mountain bike with suspension off-road down a hill. i suppose there's a whole different element of physics there.
