Hello Vital MTB Visitor,
We’re conducting a survey and would appreciate your input. Your answers will help Vital and the MTB industry better understand what riders like you want. Survey results will be used to recognize top brands. Make your voice heard!
Five lucky people will be selected at random to win a Vital MTB t-shirt.
Thanks in advance,
The Vital MTB Crew
Pretty sure that's Jackson from late 2020 or early 2021, same time Remy switched to Propain bikes (Spindrift w/ blue fork in vid).
It's an old Remy M. video that GoPro randomly posted - it's pre-SC/Redbull Jackson still on a Trek Slash. moving on!
GoPro obviously watching this thread
F1 has been brake by wire for a long time now, so the technology is relatively well developed.
Quite a few cars are drive by wire, i believe the new Porsche 911 (991 version) has electronic steering.
The real question is, why do electronic breaking on a bike, it can provide ABS, packaging? Tuneability?
No, brake by wire on F1 is for the energy recovery system, the normal brakes still work by hydraulics, like on our bikes.
The brake system literally runs through the ECU, to modulate the hydraulic pressure to maximize KERS recovery at the rear wheels under braking, that is brake by wire. Just because a human leg is providing the force for the hydraulic system (which it always will in F1, because free energy), doesn't make it not brake by wire.

The context here is wireless braking, kind of like it is in Alfa Giula mentioned above. They have brake by wire in F1 (as i wrote) but it is not wireless and "mostly" it is still fully hydraulic, front brakes a lot more than rear.
No, they do NOT have brake by wire in F1. They have standard hydraulic brakes with no boosters even, like most racecars. The caveat here is they use a Moog valve to modulate (remove) hydraulic pressure from the rear brakes, controlled by the ECU, to feed in the energy recovery and keep the overall braking forces and thus brake balance. Just throwing in energy recovery or removing rear hydraulic brakes would throw the balance front and back wildly and unpredictably.
Coincidentally, there have been failures on these systems, causing drivers to spin off the track (balance issues) and the first systems were notoriously finicky and not calibrated 100 %, causing some drivers issues with brake feel (some drivers are really in tune with what the car is working, so much so that changing the concept of the steering system can make or break a driver's performance).
As for Porsche being drive by wire on the steering, no, 991 introduced EPAS, electric power assisted steering, while 997 still kept hydraulic power assist. EPAS is getting more and more common as it doesn't have a hydraulic pump running all the time thus saving energy. The problem is with feel (Chris Harris drove the Singer Porsche just after 991s came out and said (paraphrasing) 'if you don't like EPAS, don't drive the Singer as the level of feel on the hydraulic Singer will make you hate EPAS even more'. And Porsche is touted to be by far the best in the EPAS game. But EPAS itself is nothing new, cars have been using it since the early 2000s at least (2nd gen Fiat Punto for sure), if not even longer.
Steer by wire means you have only a sensor on the steering wheel controlling an electric motor driving the steering rack, no mechanical connection between the wheel and the rack. With hydraulic or electric power assist you still have the steering shaft connecting the two. Same for braking, there's an actuator building the hydraulic pressure to clamp the brake discs in the calipers. Throttle by wire has been a constant for well over 20 years, replacing the cable actuated throttle valves with an actuator driven throttle valve and a potentiometer on the throttle pedal telling the ECU how much power is requested.
Fun fact, Ford GT still has a hydraulic steering rack as they use the hydraulic pump for the adjustable suspension system with adaptable ride height as well, thus making it worthwhile even though it consumes more fuel.
Now, back to rumors.
The Manitou Mezzer is still on sale at 40% off. Still no news or rumors about a gen2 or a dc-version?
EPAS is slightly more efficient than hydraulic steering, removes the need for power steering fluid (which is flammable) and is necessary for most lane keep assist systems.
None of the cars are running wireLESS electric brakes or steering or whatever.
I’ve been wondering about that myself. I honestly don’t know what the market would be for a DC Mezzer, but they already have stanchions and dampers. Machining lightweight crowns for a DC Mezzer seems like a fairly low cost experiment.
GM is right up there with electric steering. At this point hydraulic does have more feel, but EPAS in Porsche and GM communicate well enough. Throttle House picked the Camaro's steering as their preference in an ideal sports car, fwiw.
That is simply electric booster power steering. There is still a mechanical connection from steering rack to the steering wheel.
cybertruck has a wire.
no one is doing wireless.
Yup, that is correct. Electric assist instead of hydraulic.

I just saw this on YouTube. Has this been talked about?
Which was exactly my point, yes. Besides f1 not being brake by wire as well.
Yes. Someone posted a pic of the crank and chainring. Which is an internal use only intend product. The post disappeared though.
That‘s weird!! I answered to the post and my post is also gone. Didn‘t delete it tho…
Internal use only...? It's Intend's Rocksteady Magic crank, isn't it?
https://www.intend-bc.com/products/rocksteady-magic/
just fyi, vital didn't delete anything, but if you quote a post in your reply and that original post is deleted, your reply/quote will disappear too.
Ah, sorry, I seem to remember reading somewhere that it won't be for sale.
Sneak peak of the colorway for the new Forbidden dropping tomorrow.
F1 has brake by wire, on the rear axle.

Here, from 10m45s the engineer explains how it works.
"Rear Axle." Been covered... Now back to bikes!
It’s also a coiled frame, perhaps the dh? Or new Dreadnought
I know from my sources that it will be a new DH frame, certainly not a Dreadnought.
No information available on the release of the Dread V2
It has fork bumpers. I am excite
Some new steering damper goodness coming out of Aus
