Brake and cut-off cable replacement

My SMLRO S11 electric bike fell over and the back brake (left) lever smashed. Finding a replacement brake lever is not a problem, but finding one with a 2 pin power cut-off connector/cable is proving challenging. I wonder if it's safe to rely on the front brake to cut-off power and simply replace the back brake with a normal brake lever without a cut-off facility? I'm also curious whether magnetic sensor cut-off cables (that attach to the brake lever) would be a good substitute if I can't find a suitable replacement? Any advise much appreciated.

Tom's right the red connector looks like a Higo Mini-B 2-pole connector. There are adapters that can connect a 2-pole to a 3-pole and vice versa, if you can't find a compatible ebrake handle you might buy an adapter to plug your main wiring harness to a 3-pole yellow higo connector on a generic ebrake sensor

I'm afraid that isn't a good solution. There are complete replacement levers available. The German source for Higo adapters is CRAZY expensive!

This one? Is the shipping expensive? I know I've typically had to pay through the nose when buying from EU suppliers like Rose Bikes or Hollandbikeshop
Is it technically do-able? presumably you need a pin out diagram to identify what you're connecting to.

Yes. Is he shipping to the USA again? I paid $20 for an adapter and $15 for shipping.

BUT, how does an adapter help? All the hydraulics I've handled use the red 2 pins. I've not seen hydraulic brake handles with the yellow higo. But I do miss things!

or you could use this opportunity to upgrade it to hydraulic brake?
that's what I did, I went from cable to hydraulic and it was night and day 😁

These no-name parts are exactly why I avoid lowball eBike builds. Replacement parts can be a nightmare. Not to diss the OP. Just addressing something we see here on a regular basis.

That's an option if I can't find a two pin, thank you.

The brakes I currently have are not great. Someone suggested hydraulics. Are they easy to fit and compatible with most bikes?

For me, it was an easy installation.
If you know how to replace brake system on normal bike, you would have no problem since the only difference is brake inhibitor cable.

The only problem I heard from people is that, some people found that brake hose was too long (or short) depending on what bike you have.
In that case, you can just replace the brake hose but that would require a lot more time and effort (and money) so I can't guarantee.
But in most cases, it's fine. You should check how long brake hose (hydraulic lines) before purchasing them though.

The link provided are for Zoom, XOD and Nutt brake systems.
From what I can see, XOD and Nutt are the same thing, just different branding. (though, they have different models / variations if you look closely)
If I remember correctly, Biktrix use them too.

Very confusing but the search master is on it. When I looked at specifications and you’re photos it appeared you had hydraulic brakes Apparently I have poor reading comprehension today (every day?)

Yes, i agree. It's always a trade-off between possible risks and costs.

Thanks Timpo, very useful 😁 I'm going to follow up on these suggestions.
