wireless brakes.

Not a lot of actually showing them working, but quite a DIY feat, Tesla are looking at wireless steering and it's probably going to be normal within a few years.

10/10 for ingenuity.

 
Great invention but I'm not easily convinced it will work better than my magura hydraulic with mechanical lever.
What if for some unknown reason your front brakes lock up while casually riding
Cause by a signal from a car door remote opener.
I've entertained the idea of wireless shifting for the same reason I didn't go with it because l like the simplicity of mechanical shifter.
 
I don't think it would work too much weight and I doubt it would be simple enough. Plus those lines help cool the fluid. then you have feedback you need.

I remember the first time I rode a "Ride-by-wire" motorcycle. Strange knowing there was no physical cable connection between me on the throttle and the EFI throttle body. It did work though, and this was an early version. Me myself, I have no problem with mechanical tech and actually prefer it. But I will admit those electric brakes are pretty cool!
 
Fun for a DIY guy who has a shop and needs a project. Horrendous for the engineers at a bike company, and common sense says the liability issues are even worse.

Yup, but all the car manufacturers are looking at steer by wire, which is arguably even worse.
 
Would be cool to have for those speed demon's that don't have common sense to slow down on bike paths/ways, they come buzzing along and you mash a button and they slow down, and they don't know why............HA HA
 
I wonder how much "feeling the brakes" through your hands really matters. I'm sure it helps, and in a panic stop you know to squeeze as hard as you can, but I'll bet most of the "feeling" comes from the change in inertia the brakes cause. If you think you're about to fly over the handlebars you let up on the brake levers. And if you're about to hit the dog in front of you you squeeze harder -- so visual feedback.

Anyway, you are right about two things: just more potential failure points, and what problem does this solve -- anyway or how does it make anything better?

It's an interesting concept, but it will be a while before I'm ready to buy in.

Does any modern car have "brake-by-wire"?
Not that I'm aware of, but let's not forget most passenger airliners have no physical force connection between the pilots controls and the ailerons.
It's just wires and actuator motors.
As someone who has seen every electrical failure from botching, it does concern me. 😂

I believe the newer Toyota Hybrids (like my '23 Toyota Crown) sort of have "brake by wire". The brake pedal actuator is electronic and sends signals to the computer which can then electrically control the combination of regenerative braking from the electric drive motors (turned into generators) and the conventional hydraulic brakes. There is of course a "fail over" so the pedal can mechanically actuate the hydraulic system in case of failure in the electronics. Here is a video that explains the system:

it depends on your brakes. good hydraulic yo can feel a lot.
 
A lot of hybrids and EVs use a brake-by-wire system. In the sense that the brake pedal is an electric switch and the vehicle chooses between regen and hydraulic brakes to slow the vehicle. So not unheard of.

Also a lot of vehicles built in this century have an electrically applied parking brake, which is a kind of brake-by-wire.

The new Tesla Cybertruck has steer by wire. Which I think from an engineering point can make a lot of sense. An electrical system is probably more reliable, less subject to wear and tear, and more easily testable for proper function than a mechanical system.

You can probably feel it more with mechanical brakes, but what is it you're feeling? What tells you you're applying too much, or not enough, brake? I could be wrong, but I think it has little to do with what you're feeling with your hands or fingers. I think it's much more about the change of inertia (how much you feel like you're getting lifted out of the saddle, and what your eyes tell you about whether you're going stop in time or run over the little ol' lady in the crosswalk. If you don't think you're going to stop in time, then you brain tells your fingers to squeeze harder.

I think the relevant neurons are all firing in nanoseconds, so maybe it's hard to tell. Even on the same bike though, brakes don't always work consistently. Maybe the pads are wet, or hot If all you're going on is how hard you're squeezing the brake levers, that just ain't gonna get it.

no hydraulic brakes are know for their modulation. you dont have al that housing and slop thats involved in mechanical brakes. plus the calipers squeeze both sides so you dont have the bending of the rotor involved. .its a combo of both going on.

This is not correct at all. There are mechanical brakes that squeeze both sides, like the TRP Spyre. There are also excellent high performance mechanical brakes that just work on one side and don't bend the rotors. And good mechanical disk brakes have plenty of modulation.
 
I'm sure hydraulic brakes are wonderful but they can't tell you through manual feedback whether you're going to stop in time. You figure that out through other senses and adjust your squeeze accordingly. Same thing with hydraulic brakes, mechanical brakes, or dragging your feet (except you don't squeeze a brake lever when using Flintstone brakes).

the spyre is the only mechanical that does and its very expensive. all other mechanical only have one moving piston so they have to bend the rotor at least a little and yes I have used high quality mechanical. but they dont feel nearly as good as my 4 piston Shimano brakes. Plus I can get full power using only using one finger thats a very nice feel. you don't have all the resistance from the spring and cable.
