Brakes

I'm trying not to ask too many questions in one thread.

If I understand, I REALLY need disc brakes on any e bike.
I REALLY want auto shut off on the brake levers, but it is not legally required.

Many e bikes I have looked at do not list the brake shut off in their specs or anywhere else. Others do list it. I assume if it is not listed, it is not included.

Is it possible to add the brake cut off?? It seems the controller would have to be wired to accept the input.

Would the brake cut off be a REQUIREMENT and a deal breaker for you for a simple touring bike with frequent or continuous e power use?

I would think it totally depends on the power of your e-bike and the speed at which you ride along with bike/rider mass. An unpowered rider in good health can go ~24mph without special brakes. The factor which shifts the need in my mind is the weight of the bike+rider, and the torque of the motor. How fast do you plan to go on your simple touring bike?

If it's a hub drive with cadence sensor then you will want a brake cutoff. The cadence sensing is usually too slow to react fast enough. I would suggest you send an email query if the specs don't list it.

I've ridden 350w front and rear hub systems with rim brakes and no cut off switches, and the BBS02-equipped bike that is used off road a couple of times a week doesn't have cut off switches, but for 1000w+ systems I use them. Hasn't been a problem for me although others may have different requirements.

Torque-sensitive controllers do fine w/o brake cut-off.

Dime a dozen, brake levers with brake cut-off. as far as i've seen all controllers have this connection. I use rim brakes and actually found them better than discs as long as your wheel is straight and you adjust and lube them regularly.

I hate having the extra wiring cluttering my bars thats required for cutoff switches. I used them on my wife's 1000W (downgraded to 500W) rear hub motor build, but did NOT use them on my brother's 750W set for 500 max torque sensing PAS mid drive, and the mid drive is fine without them.
