Rotors... how big will you go? 160? 180? 203? 246?!?!
180mm in the front and 160mm in the back
Sadly the manufacturers will charge higher costs when there are really not much more on their costs.
Someone will make a killing on what should/will eventually be the new STANDARD size!
I prefer the 650mm rotor. They never warp and the pads are easier to adjust🙃
180 mm, four-pot Tektros on both ends. Stopping is easy.
Not particularly fast, but heavy.
i wanna go 246mm F+R on my DH 26" XR1100 goose
I run the Galfer 223mm rotors front and rear with MTX red label ceramic brake pads on my Trek Rail. The real world benefit from larger diameter rotors is the precise amount of modulation input you can apply to avoid lock up during steep loose technical drops. The other inherent advantage is increased stopping power. Always go up on rotors with heavier ebikes.
The Ceramic Pad are a must have!!!
Awesome!! Thanks for the review! These have been extremely popular with a lot of downhill style ebikes! Glad you liked them 🤙🏻
Thanks again! These are awesome!
I put a 255 MM brake rotor on the front wheel of my bike because I converted it to an e-bike and hydraulic brake calipers won't fit. The 255 MM brake rotor came from BicycleDesigner, which is no longer in business, it seems. The brake rotor and adapter are very expensive. About $140 for both. I'd prefer going down to a standard sized rotor if it would allow me to run a hydraulic caliper and have plenty of space.
word of warning: Not all forks are made to handle the braking forces that larger rotors/hydraulic brakes can generate, especially considering the extra weight of an Ebike (and its rider lol). I snapped a steel cyclocross fork after upgrading to a 203mm rotor.
The best brake upgrade will always always always be between your ears.
Brake issues seem to the eBike Nemesis. Both of my eBikes are new with only 100 miles or less. Although different brands and sizes, both make brake noise or start squealing. On the smallest bike, an experienced bike mechanic still can't clear the squeal. It returns within three miles from the store on a paved bike trail. Disc upgrades might help. Thanks for showing options.
my fork can only take 180mm max but I just bought some ceramic pads to try out
Upgraded my Aventon Aventure to 203 front and was told by the bike shop only 200mm would clear in the rear. I haven't gotten the bike back to look at it yet or test it out, but I'm looking forward to the upgrade in braking power, but particularly more fade resistance. I'm a larger rider and have smoked the stock 180mm front brake once on a long downhill. I think the front of the aventon could clear these but definitely not the back.
What do you think about the cable actuated hydraulic brakes?
Do you think Aventon Aventure needs a brake upgrade? If so, do you carry a thicker 180mm rotor for it and what pads do you recommend? Thanks!
The kinetic energy of yourself and your bike moving is basically all transferred into heat energy via the brakes. So the more weight the more kinetic energy the more heat. Larger rotors with more mass and calipers with better shapes (like fins for example) will allow more heat to escape. The brake fluid and amount also plays a part but not usually too much with most modern hydraulic brake fluids
Sweet review! Because those big boys are 2.3mm think they are not compatible with most mainstream calipers. What calipers do you recommend?
TRP evo
Will those 246mm rotors fit on the Blackbird, and how much will it cost to upgrade it before it's sent to me? I believe my bike should be on the next batch.
Great video, very informative! Thank you!
How are the ebike brake pads in the rain compared to organic and metallic?
Ceramic are the best pad - don’t skim on safety issues
@@BrianBriCurInTheOC interesting. I've never heard of ceramic pads. I'll have to look them up. Thanks 😊

Water makes my pads brake harder.
I’ve seen dual disks per wheel (disks on each side). The more pressure the more heat generated.
I went out and measured my RadWagon 4 and those 246 mm rotors would fit. My bike weighs over 100 lbs (45 Kg) without any cargo so I've been thinking about upgrading the brakes. Not sure about 246 mm rotors though. With me, the bike and some cargo it could easily weigh 380 lbs (172 Kg). So far my 180 mm rotors and cable actuated brakes have worked ok but ...... LOL
Will the Galfer 246mm brake rotor fit the rear wheel of a Sur-ron X Light Bee. I will buy one if it fits.
Just received my 203 and 223 x 2.0 Galfers for my Rad Mini4. They don't fit. Might be able to get either in the front, but the rear was the important one for me. Really wanted the larger 223 as the rear rotor. Clears the frame, but not the kickstand (which I need on the eBike). Neither the 203 nor the 223 will fit the Mini rear. I've got all 3 Galfer adapter posts and was able to install the 223 in the front of my old Cannondale F3 (not eBike) and the 203 in the rear. The 203 rubs the frame in the rear of the Cannondale, but a 200 might fit.
Guess I'm stuck with 180 in the rear of my Mini 4. 😞
Walking to and from work really has change my outlook in some ways
An ebike could change your outlook even more! Endorphins and fun!
Both of you…

the first time I put a 220 on the front of my mountain bike i almost flew off the handlebars
I don't understand why people put larger rotors on the front than the back. You get more braking force from the front by nature. It's the back end that needs the most braking force
@@myscreen2urs you get more mass shifting to the front when stopping that's why you need bigger rotors to stop more weight. larger rotor on the rear really doesn't do much since all the weight shifts. a small rotor or large rotor on the rear will still make the rear wheel lose traction and skid which you don't want because when it slides it's weight wants to push the rear weight left or right or make the bike fall down.
@@Timbodacious Must be a trails thing. If you're riding around on the streets, you don't need it unless you want to become a human trebuchet.
I'm afraid I would use that giant rotor as a spare tire.
You know, in a pinch. 😁😉😎
That sounds like a waste of stopping power
I see, you ride a 20" bike🙃
How do i get some of these 246's?
Why hasn't any brake company developed a floating caliper, especially for dh, enduro and e-bike?
It's a standard on literally every other vehicle on earth.
Could have used these brakes yesterday. Got into an accident yesterday on an electric bike with just a front rim brake.
oh no! Hope you are okay
Rim brakes suck never use them.
Would those 246mm rotors fit on a radrunner??
I would like these 246mm rotors for my road e-bike. This e-bike is 120lbs and goes fast.
The current 203mm system is just decent but I can tell they're at their limits (Shimano Zee hydraulic calipers & BrakeCo 203mm rotors). They are *not* able to lock up the front wheels but there are a lot of factors that go into this.
One thing for sure is this bike quickly eats through standard resin brake pads even with their air cool heat sinks. So I am currently using longer lasting metal pads but they can be noisy. Maybe the dynamics of a 246mm rotor can work better with quiet resin pads and allow them to last longer because of reduced max heating.
We have brake pads meant for ebikes too
How can I get the 246mm. How much are they going for?
Check out Area 13 Ebikes
What size are on the foxbat thank you
180mm
Easy to want biggest brakes. But the overall components were engineered as a system. Performance has limits before integrity is compromised, and then bad things happen. 400mm rotors would be cool, until your handle bars bend from deceleration force.
If they warp, you're gonna know about it
So, let's just go back to far lighter weight hydraulic rim brakes...jk Though it is shame more are not used on commuters.
The biggest advantage to a larger disk is heat dissipation, not the minimal difference in leverage. Otherwise, why not move the mounts up to the brake bridge and use 20" rotors?
The average person will not feel the difference. Most won't ever ride hard enough, or carry near enough weight to ever worry about fade on a 160 rotor. Few will ever have a use, much less need, for four piston calipers, though their power and modulation cannot be denied. It's not that these aren't better, but if you don't need rhem, don't drag around the extra weight, wear and maintenance.
... and cost.

These rotors are literally larger than a lot of motorcycle rotors, you ride bikes with 4 inch wide tires, you ride bikes that can send you flying at 50mph uphill with minimal effort, at what point do you just purchase an electric motorcycle.
i thought the 220mm ones on my ebike where huge
These are bigger!
@@Area13ebikes i know i thought the 220 where the largest out there now i find out there are bigger ones cool.
almost the size of a large pizza
yeah, almost!
Run hydraulics and pit bike roters , your going to fast for that bycicle roter
U dont need huge disc on that ebike. Its not even that powerful of a bike lol
