Do MTB Brake Brackets cross over to Ebike ? 200 mm Front, options for better brakes.

It's not the middle East, that entire region do be a British colony. They be hop'in dee sheep be daa dumb and ain't able to figure it.

Problem is the sheep are in government as well don't know their arse from their elbow.

OK I found my BB7 stuff and rotors, Will the BB7 work with the stock brake lever and cable setup with correct spacer?. I know just look but I want to know before I go try and put it all together.

BB7 is a regular International Standard disc brake system. It interchanges with any other IS brake.

 

[Moretorque]

Thanks. I got it going.

220mm rotor.... actually its mounted the wrong way around on the picture bracket

 

[Moretorque]

How much better than 203mm ? Thanks.

How much better is the BB7 stuff compared o the stuff you get on a cheap Ebike. So far my setup with 203 mm works good.

Putting a magnetic motor cutoff switch (reed switch) on my TRP hydraulic brake handles was not hard at all. I just used a little epoxy and a zip tie to hold it in place while the epoxy set. The small donut shaped magnet is glued to the lever right above the pivot. It works great. Grin includes a drill bit with the switch, but you don't need it. I used JB Weld and holds well.

17mm better

OK

Something like these

I still prefer Rockshox forks or similar with a 220 mm rotor and a 4 pot hydraulic brake. This where one gets to the point of needing a tapered steerer tube on the forks along with the frame to take the tapered steerer. I do have a set of Rockshox 35 e-bike forks with the 1.8" tapered steerer tube but they still only rate the fork for a 220mm rotor, perhaps we are looking at the strength of the frame's head stock area. I am reminded of my old motorbike where the front wheel was filled with two big rotors.

Those are the rims I always ran on my 29er's, I have no 27.5 but can try a 29 on the front of my 27.5, I just ordered a 220mm for my ebike.

Yes, I run two e-bikes which are mullets, built on NOS frames with these I have slacken the headset angle to a more modern setup. So one is a 27.5 front and 26" rear combo on a 26" frame the second is a 29" front and a 27.5" rear combo on a 27.5" frame, There is a third with my 29er where I have put a 27.5" rear on it. They all ride fine. Picture is the 27.5"f - 26"r combo but I only need a180mm f 160mm r rotor combo on this, covered more than 3500 miles on it on the modified TSDZ2 mid-drive.

That's a big old rotor, still prefer hydraulic brakes. But with hydraulic brakes on that rotor may overload the fork bearings, the Rockshox 35 silver forks on my 29er max out with a 220 mm rotor.

No doubt ...good hydraulics are set and forget and majorly superior.

I work on bikes every day. I rarely find hydraulic brakes working as intended. When they work at all, they need to be bled because the levers have too much takeup and they usually have contaminated their pads. They often do not work at all.

When brand new they are fine. Just like cable brakes except not for as long.

Because people buy cheapass Aliex stuff and wonder why it s not working.

 

[Moretorque]

No they are not as good as good hydraulic but with the new 220 MM rotor I am getting they should be adequate. I am like 340 and with 203 FnR it stops me from 30 good. If I was on hills NO!

Yep, I have fitted and run on Clarks and Shimano hydraulic brakes on more than six e-bike builds and had no problems, I have tried the Zoom, Meroca, etc hydraulic brakes from Aliexpress, they are a bit hit and miss, the worse ones I tried early on was the Zoom / ZTTO etc line pull hydraulic brakes which leaked within a few weeks. But I have used a set of Meroca four piston hydraulic brakes and they were fine, just the luck of the draw or sod's law perhaps.
