MythBusters Bicycle Episode?

I'm sure anyone (in the US) who hasn't been living under a rock for the last few years is likely familiar with the show "Mythbusters". In the show, team of people take myths and test them to confirm or bust them; also a lot of things get blown up. Many of the episodes are themed such as "Movie myths", "Shark myths", and "Truck myths".

I would like to see a bicycle myths episode.

What are some bicycle myths that you might like to see tested?

I'd like to see them test the safety of a bike helmet in really ridiculous situations, such as navigating through a mine field, or a hail of gun fire.

Or a design challenge pitting Jamie and Adam against each other to design the ultimate commuter bicycle. At the end of the episode, they would have to ride the bicycle through an obstacle course filled with urban hazards such as broken glass, pot holes, car doors flying open, simulated torrential rain, etc.

Actually, they did have a bicycle episode. Something about conserving energy by drafting other cyclists.

Id like to see the logistics of drafting and how much you can save

prove breaking away wrong.

test stopping.

see if carbon explodes and make it explode.

see if they can break long enough to pop a tube.

see how much force is needed to break a stem.

Actually, they've sort of run out of myths. A lot of their later material is/was movie special effects, which were never claimed to be real or possible in the first place.

The durability of different frame materials in different conditions.

To finally end that steel vs carbon vs alu vs ti vs whatever debate!

One big myth is what keeps a bicycle upright. Most people will tell you it's because of the gyroscopic behavior of the wheels. However, we know it's actually the headset angle.

I saw that one. It was ridiculous on a number of levels. The guy rode a full suspension MTB in some sort of body armor get-up, he drafted a tractor-trailer at 20mph, and they used heart rate as the proxy measurement.

How hard would have it been to scare up a PowerTap? Hell, just drop a line in the Road Bike Racing forum and they'd have half a dozen guys who'd do it.

Myth to test: the safety of various riding practices... Parents still teach their kids to ride facing oncoming traffic because it is 'safer.' There is one myth to test. Or the 'ride like you're invisible' strategy.

I agree with the fact that their shows are getting ridiculous though. Watched one last night where they proved that superheroes can't get changed superfast in a phone booth (which of course they CAN because they are SUPERheroes who can do things that the MB gang can't)

Yes, it was quite rediculous.
I think this was a from that episode, while they were goofing around between takes, (different bike):

Actually, at least I've seen people debate the whole issue of breaking a rim by braking too long. There's gotta be some 2000' descent hill where they could just let it head down the hill at 20-25mph while riding the rim brakes to build up heat, then use a thermocouple or something to see how hot it gets the rim. For failure testing, I'm guessing it would have to be under lab-type conditions, like their tire-blowout test.

Have a bike wheel coast in contact with the drive wheel of a pickup truck with the bed removed so you could apply full bike brakes while still getting 25mph wheelspeed or something. It would be interesting to see if the brake pads would overheat to thermal failure (like brake fade from overheating on car brakes) or if they could hold out long enough to damage the rim. Ultimately, I think most people find bicycles boring, so it probably wouldn't make it on TV.

Or one that would stay strapped to his head instead of coming off at impact.

One hotly contested topic on BF is how much power you gain (if any) on the upstroke using clipless pedals.

Wait, WTF?
I always assumed people do this because they're stupid or lazy about crossing the street or something.
But there's a belief that it's actually Safer??
Where does this come from and whats the 'logic' in that being safer??

Well, if one rides under the assumption that every car is out to hit you, it is a tremendous advantage to be able to see them coming towards you rather than having them coming up behind you.

When running, I always run facing traffic. When biking in the city, it's pretty impractical because of stop signs/lights and turns and whatnot. But out on rural roads, I can't think of any tactical disadvantage to riding on the wrong side of the road. (i don't do it though).

Well, since your speed opposes that of the oncoming car, a possible collision will be that much worse...
Also since you're moving towards each other, your reaction time before potentially colliding is much less than if you were both going to same direction. (Use a mirror or get into the practice of turning head and looking around...)

Then there's all the other bikes in the lane going the designated direction who are running into you...
(this would apply to running on paths as well... becoming an obstacle to other runners...)

I'd also like to see them test one as a flotation device after crashing into the ocean after skydiving out of a plane on a mountain bike.

The real issue is that most auto/bicycle accidents happen at intersections. When you ride on the wrong side of the road, every time you approach an intersection you are coming from a direction that's not expected by other road users.

I would like to see the Mythbusters do a Bicycle show more along the lines of Utility Cycling. Maybe a show based on a CSX Commercial… How much can you haul/pull with, or on a bicycle safely. Or, how efficient is a bicycle for such things as a machine.


I think it would be great to help break the general publics view that bicycles are just toys, and not for everyday use. Could be fun to see how much a regular person could move with a bike...

Exactly.

Try this... next time you drive (or ride for that matter), see how often you look for oncoming vehicles (including bikes) in the wrong lane.

I'd like them to test the myth that commuting by bike actually saves money over driving. Saving gas maybe, but they have to eat the way I eat and count the grocery bills!

That's why I said it's not practical in the city and contrasted that with rural roads (where there are few intersections, and few cars to meet at the intersections you do happen to come to).
