Cableless brake system
 

Talk about going around the block to get across the street. Why do people feel it nessecary to re-invent the wheel?

I think he is using the bike as a development platform.

Psh... had that decades ago. Coaster Brakes = Wireless brakes.

:Sarcasm:

Psssht....sneaker jammed into the rear fork BMX style
The Skid, fixie style
The Fred Flinstone, DL-1 in the rain

Rod brakes. BTW I don't want anything computerized on my bike. Shoo, Di2 and campelectro!

Need an iPhone app so I can stop without touching the handlebars.

Need an I-phone app so I don't even have to ride the bike.

No thanks, I'm not trusting electronics to stop my bike. I can see it now "Golly it seems the batteries in my brakes have gone dead and I'm going 35mph down a hill!!"

You have nothing to worry about. This technology won't be used on bicycles. Just airplanes, heavy duty equipment and trains.:lol:

I take it this is an advertisement for Dynamo hubs.

That's Di2 is so silly. Now you gotta carry spare batteries lest you jun out of juice and end up with the world's most expensive single speed.


edit:

btw, dig the One-Piece crank on that bike :lol:

Ha hA.... you engage your brakes via the internet.....!
.

I want apply someone elses brakes.

Where's the TdF rules committee when you need them?

Not to mention:

Mind you there is nothing wrong with cable operated or hydraulic brakes, both technologies are reliable and work well. An area that could use some improvement with electronics is shifting, in that with modern precise shifting mechanisms, cables can easily get far enough out of adjustment that shifting no longer works. One possible electronic solution would be a box that sits at the junction of the down tube and seat tube, this unit is powered by a generator hub, the unit then sends power to the shifter which becomes a simple 3 pole switch, when the switch is moved to the shift-up position, a small stepper motor turns a preset amount, and pulls or releases a cable to the derailleur, since the cable is only about 1m long, it would better stay in adjustment. Adjustments would be made not to the cable, but via a dial on the control unit.

Given the stupid responses to wireless brakes and Di2 in the 41, posting it here is just asking for trouble! ;-)

And for clarification, Di2 batteries last a long long time. It's not like you'd have to recharge it every other ride. Also I would imagine if the battery goes dead on a brake system, you would first get a warning of the battery dying, then they would engage instead of leaving you hanging.

Oh great so you run out of batteries and do an Endo!

Alright I'm out haha, there's no winning against the C&V crowd when it comes to new tech. There would obviously be a real safety system connected to it, if it actually was to be a consumer product, which it won't.

Sounds awesome! - Or you could just twist the barrel adjuster on a cable?

Didn't Mercedes do brake by wire on their cars a few years ago? I've heard stories of them just turning off but then maybe that was slander.

Yeah!!!!!!!!!!

Why would anyone want to ride something beyond the Boneshaker. Good thing I have my trusty Underwood to tap out this response, attach it to Semour my trusted carrier pigeon who gets to a dude on the intrawebz to post on this forum. Yeah. R&D sucks.

RFC 1149 FTW! https://www.ietf.org/rfc/rfc1149.txt

How much it weights?

How long untill u have to re charge batteries?

It stops working in a rainy day??

Morons have accidents with any type of brake system, what makes you think this will stop the problem??

Well, shimano sure have this already for a few years already.

Patiently waiting for the new Campy cableless braking system.

Shimano already has battery-powered cable-less electronic shifting. I actually kind of like the concept, because it permits one to locate multiple shift controls, e.g. one at every hand position along the drop bars, and it could be morphed into an integrated single-control system, if desired.

VW/Audi and other German automakers have had electronic parking brakes for several years now. I am not too keen on them, because I like to be able to modulate the parking brake force w/ a good old-fashioned pull-up lever alongside the driver's seat. Also, you need VAG-COM software and a USB-OBD cable just to replace the rear brake pads and/or rotors, because you have to tell the brake computer to back off the pads.

I worked at TRW when they were developing electric power steering, which has since become somewhat commonplace. The major debate centered on whether to retain a rigid mechanical connection as a backup. (It was retained.)

Never mind, I want a robot to ride my bike so I can devote my time to less strenuous matters. :rolleyes:

I said re-invent the wheel, no invent electricity...

My point being, cable brakes work and have been working excellent for decades and this guy is simply over thinking and inventing something that we already have and do not need.

It would be like trying go find a better way to chew food or breath. It's moot.

I don't even see the point of those wireless bike computers. There's so much that goes wrong with them than with the wired ones.

That's not fair, you read the article. What would happen to BF if posters actually started reading the article before spouting forth? BF would be reduced to intelligent discourse based on fact.

It's not like the principal investigator said anything like

'The wireless bicycle brake gives us the necessary playground to optimise methods for operation in much more complex systems.'

:):):)

I take it you have no clue about research and development.
