there used to be a 8s sram group especially for ebikes, customer didn’t like it. they want moar speeds moar = better

Run a road cassette

May be excessive for you but most of the trails I ride on my ebb are old moto trails that we rebuilt and they're steep af up and down, I spend quite a bit of time in 11/12 with a 34 chainring. To Timo, one of the cool things about ebikes is lowering your seat and still having pedal power, it allows you to climb steep, techy trails easier.

It’s also a coiled frame, perhaps the dh? Or new Dreadnought

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.

None of the cars are running wireLESS electric brakes or steering or whatever.

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...

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, brake by wire on F1 is for the energy recovery system, the normal brakes still work by hydraulics, like on our bikes.

It's an old Remy M. video that GoPro randomly posted - it's pre-SC/Redbull Jackson still on a Trek Slash. moving on!

Pretty sure that's Jackson from late 2020 or early 2021, same time Remy switched to Propain bikes (Spindrift w/ blue fork in vid).

Those 5.10 Kestrel shoes are from ~2019 I believe.

There's no way of braking with hydraulic brakes if they have a problem. It's easier to build a fail safe into a brake like that than it is with a hydraulic system, surely? e.g. if the caliper losses connection to the lever it could be set up automatically apply X amount of force to bring you to a controlled stop. From personal experience if you encounter a problem with your lever, hose, or caliper on a hydraulic brake, there's nothing you're doing about it. There's no redundancy or safety built into the system at any point in terms of failures.

oohh boys, wireless brakes are not coming to normal bikes due to weight penalty. The best use case for wireless brakes is the F1 style of brake. You have an engine, motor, some shit that takes power away/recharge batteries when braking. Use that energy before the calipers with abs (on an e-bike you can have it sliding just a bit, never fully locked for example). Lever feel would be something like incresing spring force untill you actuate the brake itself. To be fair, there is a mechanical way of doing that, not even wireless. For the front of the bike...

Electric power steering motors for example have dual windings so even if one of the two fails, the other can still power the steering. The car of course throws a catastrophic error, probably even goes into limp mode and forces the driver to stop ASAP to prevent any further issues. The amount of bureaucratic systems in place to develop these kinds of things in automotive fields would probably be quite surprising to many people, on the other hand there are a ton of products in the bike industry where it's really questionable if even the basic FMEA was made at...

Automotive systems have built in redundancy. The BBW and SBW systems have hydraulic and mechanical backups in case of failure. (I'm a brake controls engineer). True brake by wire, electro-mechanical (EPB's), would still have a secondary redundant power source, possibly even a third, to prevent any 'no brake' scenarios. Wireless braking is sketchy and I'd personally never use it. Always have redundancy.

Not only that, but the military is much more risk tolerant than the general population. Military aircraft require insane amounts of maintenance and still go catastrophically wrong relatively frequently because of how complex they are. Their operators accept those risks as part of the job. Not to mention that fly-by-wire is used in fighter jets to keep them in the air, because they're often so aerodynamically unstable that any human pilot would crash one using traditional controls. It's not just for the fun of it.

you know the saying "it looks like a session" it's because it is.

The new Corvette Z06 is also brake by wire, but most reviewers don't love it compared to conventional brakes. I'm fine with hydraulic brakes and even shifting and dropper posts using cables. I don't have problems with it and I don't notice it while riding, so I have doubts it's going to make mtb'ing a better, more fun experience overall. OTOH, I did just get a cable-actuated Eagle drivetrain for a REALLY good price, so there's that.
