Would you use wireless brakes? Would the lack of feedback from the lever put you off? | Watch the GMBN Tech interview and detailed look 👉 ua-cam.com/video/qTxtrt49Sxc/v-deo.html
More reasons to get £15000 out of us for s push bike ? Think it is time I brought a MOTORCYCLE instead , nice DUCATI for £10,000 a lot cheaper and you get a shag instead of looking a twat in spandex and a kids helmet !
This is absolutely amazing ! Not just designing and building that on your own, but also daring to actually ride it pretty fast on real trails. And massive props to Blake for actually making a front brake version aswell. Im pretty certain quite some people would dare to try out the rear one but certainly only very few would dare to even touch that little front brake lever , for obvious reasons. 😆
@BlakeSamson8 100% mkII needs to happen. I'd ride them if I could afford them. People fly planes with no mechanical connections. There's literally planes that would be impossible to fly with a mechanical yoke. Why can't bikes be fly by wire, too? I'm on board.
@@pewsician2388 planes have decades of engineering and they are still crashing sometimes,yet their battery wont die midflight, and there is still physical cables connecting all the stuff in plane. On bike it has thousand opportunities to fail from error in electronics to lost signal or dead battery. And if battery dies once a month, you will probably end up crashing into the wall once a month
@@BigAsianJesus not necessarily, just have two separate systems for each brake so if one fails, you can use the other, or just brake by wire with regen braking
@@BigAsianJesus On semi trucks, the air system could fail and there would be no brakes. The safely approach used there is that when there is no air, the powerful brake springs will stop the vehicle. Maybe an approach could be that when the battery dies, the unit defaults to full brakes. Not sure how to work something like that out though.
Great video Blake! I do have some suggestions regarding the implementation of modulation. Two key things here: the actual modulation in the caliper, and the user-end's perception of modulation in the controls. I would suggest attaching a stiff spring between the servo and the cable pulling the caliper so that the braking force ramps up as the servo pulls more. On the lever side, you could use an elastomer or compression spring that pushes against the lever blade on the end part of its travel. You can use a cable brake lever to pull on the trigger part of the mechanism. Last touches will then be to fine tune the bite point on the caliper side to match with the lever starting to engage the resisting spring.
I'd reccomend using a load cell for control on V2, should make it way easier to modulate. Edit: if you're feeling extra adventurous (and have a spare set of handlebars, which you lads 100% do) you could put the electronics inside the handlebars for an extra sleek look
If you're doing the mark 2, i've got some ideas: Put a heavier springs on the triggers so they feel more real. Shorthen the servo arm for so they don't feel on and off, For flexing you could make the mounts also sit on the frame and tighten them with some zip ties. Nice and fun project tho!
Love Blake and the breadth of his skills. I’ve been getting into diy electronics the past couple years. The key to making wireless brakes actually work is some type of force feedback like sim racing steering wheels.
Instead of using the servo to pull the cable, use a strong spring to do that. Then, use the servo to actually *release* the brake. That way the system is fail safe, so if there's no power or the servo breaks, it applies the brake.
@@piast99 Good point. Perhaps you could have different systems for the front/rear wheel. Use fail safe at the back, but not at the front. (so it won't send you otb on power failure)
@@kidShibuya Not too many cars atm have them really. And those cars have redundancy of hydraulic brake system if electric one fails, that wouldn't make any sense on bikes. What advantages do you think there is to wireless brakes on mtbs?
@@Dirtypandasan The main advantage, which I think is a great one, is that a non hydraulic, non cable actuated lever doesnt have any resistance to pull against. That also means no fatigue in the brake fingers. Which actually is my only problem when biking. I think that, even though it seems like a terrible idea, it can be a really great one actually which I would definitely love to try out in a more refined iteration.
they are for sure gonna come, for the feedback I reckon they'd be using haptic feedback like the ones you found on game controllers. the genuine feel for the hydraulic oils I am guessing is the brake lever would have some chamber of oil in it, with a sensor/servo that replicates the feel of it presssing on the calipers, say the equal volume you press on the levers, would be the same volume of force on the calipers.
For my bicycle camper, wireless brakes are the BEST idea. They will essentially be an e-brake anyway and only used when necessary ie. To keep my camper from rolling backwards down a steep hill.
Nice work as always mate, check out the settings for your transmitter (the thing on the brake lever), some have the option to set "expo", meaning the servo will ramp up in throw, the further you actuate it.
I made my custom 36er bike with zero cable stops in anticipation of a future wireless braking system,. I'm ready! It already has a SRAM Eagle AXS rear derailleur.
Keep going on a mark 2 please. Imagine how clean an AXS or Di2 bike would be with wireless brakes. No need for finicky internal cable/hose routing!! Mind blown.
If you get a transmitter that lets you add an expo curve on the channel you're using to control the brake lever, then you could maybe use that to fine tune the modulation
When I first saw the teaser on Instagram, I was skeptical. I thought how is an RC servo going to provide enough torque to pull a cable actuated brake? Then you pull out these cable actuated hydro calipers. I didn't even know that was a thing. The way you pulled the guts from an RC remote and then fabbed it all together is amazing. I cant believe you rode with them down those trails. You must have rode them long enough around the neighborhood first to build some confidence. That would be freaky to not have the finger feedback. As others said though, you can probably add a stiff spring and that would give the similar feedback. This was a realy cool video. Nice job Blake.
I think a good idea to address the modulation issue would be to use a weight scale sensor/load cell (someone else mentioned that too), which does not have (to my knowledge) any moving parts. This way the break levers will be stiff and you could modulate the brakes purely by force applied.
For a MkII you need to use faster servos and a transmitter that is mappable for it's actuation curve. You can also get linear servos that would be much easier to get to work with those calipers. There's loads of info about brakes like these for nitro powered RC cars, boats and planes as they've been dealing with this for decades. The big issue though is getting any feedback through the levers, very hard to do without making it very complicated and bulky but it is possible. Maybe something with a gyro on the hub to sense deceleration rates and lockups could work?
Depending on what radio system you're using, you could use a single transmitter on the bars and use a separate channel for each brake. That would result in one less battery. A faster servo would probably help, something that can mimic the same speed as you pulling the lever. This was really cool and probably a lot of fun to build.
Blake, what would really help on modulation is a cam shaped lever arm on the servo actuator. This could be tuned to multiply the torque and the amount of movement as it pulls the cable actuator. Since the lever is producing a linear signal, the cam would allow for a modulated actuation, creating a more natural feel to the brake progression..... maybe? LOL Just a thought as I watched this very cool video. I'd be happy to come back to the UK and work on it with you and ride those Forrest of Dean trails. It's too cold to do much riding here in Canada right now.
100% need a Mk 2 - BBW is definitely the way ahead - cable-less is the future, just need to find a way to program in brake feel into it, great effort Blake!
For better modulation, you should put a microcontroller between the receiver and the servo. You could then run an "expo" function to make the levers less touchy.
I was just thinking about this the other day, with all the wireless shifting we have now. Maybe the big brands are also doing in secret. 😊 would be sick to see it all and improved! Wireless and clean cockpit!!!
Awesome! You should try and put a load cell in the lever, since that's more like how analog brakes work. It would also be interesting if you made it a zero throw lever that just reacts to the force you put in.
A couple of HV servos, micro receivers and some expo programmed in, I can see this being a bit more intuitive! not to mention smaller form factor! Tempted to build something similar with HS33s for my trials rig.
This thing is awesome. But i think it would be better for slope style because you could get infinite barspins and tailwhips. But for example for DH racing its kind of a thing you dont need. But this is sick i always thought about why do people make electric derailleurs but not electric disk brakes. Sick Idea
Surely you could tighten the springs on the levers to make modulating the breaks easier? Also on mark 2 maybe try putting the levers into the handlebars? Or something like that.
Absolutely keep improving this concept. Push it! It'd be amazing to get force feedback into the levers which corresponds to the braking pressure applied like you get in a car with electronic steering.
I see the main advantage when you want to have more than one brake lever for different hand positions. This is the case for drop bars (regular brake lever position plus a lever on the top) and for TT extensions (no brake lever available today). For a mass production, - there should be some redundancy built in (e.g., more than one channel for the wireless transmission). Also it must be ensured that > 2 bikes with wireless brakes do not interfere (problem seems to be solved for wireless shifting already but I am not sure with Blake's prototype). - modulation through the lever is definitively required (it could be electronically tuned / calibrated) and there could even be an automated blend of front and back wheel braking (like in cars today), even ABS aka antilock system to have the shortest brake distance for emergency braking Also it would be good to have power regeneration during braking to charge the brake actuator (and wireless shifter battery plus some optional lights fron and back).
It will definitely become a thing in the next few years as brands start making and testing them until they are fully trustworthy. Nice job managing to make that work
Being an avid RC racer for 30+ years. Technology has come a long way. There's so many adjustments that could be made with the sensitivity and response of the servos. But nothing will work as well as hydraulics with feedback. I bagged on your idea on Instagram pretty bad. But after watching the video, there's potential there. But then again....why? What would be the advantages? I honestly don't see any other than no hoses and cables.
Awsome! I imagine that in one of the next versions it will be possible to get rid of the levers completely. Just hold the grips with all fingers and add two load cells under the index fingers.
That is an insane build Blake 😊🤘 Love Blake Builds 👊 Wireless brakes will become a thing in the future I think but it would have to have a backup battery built in I think. Looks insane having a bike with no cables on it 😂 Awesome stuff Blake and #GMBN 🤘
With a standard brake, you can crash in case of mechanical failure with the lever, cable (or tube), clamp thingy or the disc. Now you can also crash if the battery dies or is empty, if the servo dies, if the remote dies, if the remote battery dies or is empty, if the signal is lost or jammed, or if there's a bug in any of the chips software. I propose for the next step you connect the brake lever to a remote server on the internet that actually control the braking.
This is impressive. From a use case - It doesn't seem like it's better than Hydraulic in any way at all so I can't see it catching on. But concept and execution is super impressive.
So for v2, for it to really be rideable, you'd want to change the control system somehow. Currently it's trying to match displacement. The lever (likely) is turning a potentiometer to measure displacement, and Inside the servo is another potentiometer that turns with the servo, creating the servo feedback loop (they could use digital encoders, but my limited experience with RC servos had potentiometers) Replace the two potentiometer loops with strain gages. Then the lever can be firm and transmit how hard it is being pulled, and on the brake end, servo feedback loop is not against the desired position, but the desired force....
Awesome job on this! Seems like a cool project to try myself! Have you considered using some sort of rubber block in order to create some resistance in the lever? It may help with the modulating issue. I think the squeezing through the rubber may be a nice way to mimic the resistance of regular brakes levers.
Electric and hybrid cars are mostly brake by wire. Pedal feel is simulated. But there is a backup hydraulic conventional system if you push the pedal far enough.
I have been working on wireless brake ideas for my bicycle camper. I was considering a mech or hydro brake line with a quick disconnect of some type, running to an extra brake lever on my handlebars. I eventually headed down the path of electronic actuators and some R/C parts. I think I am gonna mount some small actuators on a tiny lever right on the caliper, no brake cables at all. The actuator will need wires though, obviously. I could probably put a battery right near the caliper, but my bike is an emtb, so it already has a battery. It is all gonna be an experiment, that is for sure.
Wow. 4 more batteries to keep charged. Fandabydozy. That's an amazing achievement and great video. But I feel it's a solution looking for a problem. Still I'm sure big bike brands will be patenting a solution shortly, maybe Blake should get in ahead. Solving the feedback through the lever would be the big ticket item.
Nicee. you could use exponential settings on servo controler to flat out the trigger linear curve. In that way you can control the amount of modelation
it wouldn't surprise me if this got put into production this is the future of bikes. Look at bikes already Everything else is wireless on a bike. dropper, gears, suspension. So why not breaks great idea
Do this again with brake levers that move maybe a mm or two and modulate using a pressure sensor. Pair that up with a faster actuator and I bet they would feel pretty good
Not needed on the front, you could just run the cable through the stem cap and achieve the same thing, which is safer especially if using a wireless rear. On the back with some refinement, maybe using a longer lever, yeah for those willing to go through with it and with replaceable batteries, plus one wireless brake is half the development work.
Honda implemented a brake-by-wire on their last NSX, dont have a clue how they manage to get any feedback on the pedal but they did it, reliably enough for them at least (and Honda people don't usually mess with reliability). Maybe there is a future for this, but as always, at what cost ? Great job tho, you prove to be quite smart and handy on this particular series ;)
@blake Awesome idea, your abilities amaze me more and more! What about attaching a Potentiometer to the brake lever to control the modulation? They're cheap and can easily be hooked up to the wireless sender! The Potentiometer on mobility scooters have quite a lot of modulation. Obviously they're used to accelerate but it's the same as pulling the caliper. Definitely looking forward to version 2!

You would need to build in feedback for them to be useful.
I can understand wireless shifting but not this.
No. Just safety concerns. Ahem, what if it fails to receive signals?
Never, brakes must work

i think thats the only good application for that. the bikes main brakes shouldnt be wireless.
Super rad video blake 😂
Side note
I love cables😂😂 lol
Can you install the servo straight on the hydraulic leaver of the caliper?
Great build. Do a version 2. But tie it into an E-MTB.
Wow. 4 more batteries to keep charged. Fandabydozy. That's an amazing achievement and great video. But I feel it's a solution looking for a problem. Still I'm sure big bike brands will be patenting a solution shortly, maybe Blake should get in ahead. Solving the feedback through the lever would be the big ticket item.
Go for it Mark 2!!
ABS would be really cool to have on a Mk. 2! I think it would be easy to implement, too.
Nicee. you could use exponential settings on servo controler to flat out the trigger linear curve. In that way you can control the amount of modelation
Thank you for an utterly brilliant video.
Solid bar from servo to lever for fast retraction, load sensor on the actuator handle to better control motion...
How many drills you need? Yes!
it wouldn't surprise me if this got put into production this is the future of bikes. Look at bikes already Everything else is wireless on a bike. dropper, gears, suspension. So why not breaks great idea
Do this again with brake levers that move maybe a mm or two and modulate using a pressure sensor. Pair that up with a faster actuator and I bet they would feel pretty good
Great job! Maybe try making the levers longer. It'll help with the modulation I think...
Not needed on the front, you could just run the cable through the stem cap and achieve the same thing, which is safer especially if using a wireless rear. On the back with some refinement, maybe using a longer lever, yeah for those willing to go through with it and with replaceable batteries, plus one wireless brake is half the development work.
Honda implemented a brake-by-wire on their last NSX, dont have a clue how they manage to get any feedback on the pedal but they did it, reliably enough for them at least (and Honda people don't usually mess with reliability). Maybe there is a future for this, but as always, at what cost ?
Great job tho, you prove to be quite smart and handy on this particular series ;)
@blake Awesome idea, your abilities amaze me more and more! What about attaching a Potentiometer to the brake lever to control the modulation? They're cheap and can easily be hooked up to the wireless sender! The Potentiometer on mobility scooters have quite a lot of modulation. Obviously they're used to accelerate but it's the same as pulling the caliper. Definitely looking forward to version 2!
This is brilliant!!!! Completely crazy, and scary but brilliant AF hahhahahaha
This will be a reality in the near future!
It's ridiculous, but love watching Blake do just about anything.
