i just crashed my sondos thin. the crash broke one of my brakes: see picture.

and now i need a replacement. most links to brakes here are to american shops. can somebody send me some links to brakes from european shops, because i don´t want to wait so long for the new ones. which specs do the brakes need to have that they would work for the sondors thin?

ps. this post is all in lower case, because it hurts if i move my left arm xD

Nice find.  The only issue will be you are going to need to attach the appropriate connectors yourself as those levers have bare leads.  Hope you saved the remnants of your original lever!

^ What he said. Nice find! :)

@Martin Kurth Welcome to the Sondors Owner Forum! Great to have you as an new member!

 My favorite euro bike online retailer, at present, is Chain Reaction Cycles.  http://www.chainreactioncycles.com/

The usual first upgrade to better brakes, on our bikes, is Disc Size. If you desire better modulation, more stopping power per grip pressure or less brake pad adjustment the hydraulics offer an advantage. It you live and ride in a particularly cold climate, hydraulics might not be the better choice. 

The Shimano Deore M615 are offered at Luna Cycles here in the US for $120 a pr, (front and rear) and I believe they ship to all Europe. https://lunacycle.com/shimano-deore-m615-hydraulic-brake-set-with-bafang-ebrake-cut-off/

Unfortunatly the offering from Passion eBikes is priced at $82.45 per wheel.

Hello Martin,

Wendy Xie's Pasion EBike is a well known Sondors / ebike vendor and she has the same brakes for US$95 shipped free.  I suspect the deal is the same for your country and currency.  She ships Fedex International so delivery from China to the US is fairly swift.


The price is for a complete brake set.

i found only on https://pasionebike.de.aliexpress.com/store/1088910 brakes with cut off power contact to controller.

Yes the issue you will find is that brake interrupters are rare while of course brakes themselves come in many varieties.

The Magura brakes are the only other factory-built option if you want motor cutoffs built into your brakes.  There is, however, another option to allow you to do-it-yourself.  From a cost standpoint it makes no sense but if your desire is fixed on a particular type of brakes, this relatively new product will allow you to wire up the brakes of your choice.


At US$70 for a set, plus shipping plus your time and effort to implement them to the brakes of your choice, its not a choice I would make.  But its there for you if you want it.

For the money, if you desire a premium product the 4-piston Maguras are the easy option and provide more stopping power than you will be capable of using.

what I surmise from this thread is that Martin not only wants to upgrade his é brakes to hydraulic but would rather buy them at a European shop and have them install'em.  His lack of English and unclear, abbreviated posts leave us unable to zero in on his quest and it just seems like he's taking a stab at anything he reads here or on other sites because he's switched what he wants several times. Most major bike brake companies offer hydraulic eBrakes. Even Tektro has eBrake Hydraulic levers but there is also the problem that some levers are no contact circuit on activation, or contact connect curcuit on activation. Magura offers either. I have no idea where Martin is but a Local Shop Vendor or Magura rep is where he can probably get the best advise and decide what he wants and who he can get to install them. Hopefully he can find a native speaker to exchange with, not a single one of our regular European members has stepped up to the plate to help.

Hi, Matt!

I'm from Europe and my controller in Sondors X (for Europe - 250W) is SD48ZWSR-LD12i.

Now I'm checking the bike and how can I see, the brake "in action" close the electric circuit (as presented on the second photo).

What do you think, do I need the closer-brakes?

Thanks for helping!

All of the KT controllers behave the same way, so the fact we may have different Sondors models means nothing.  Our experiences are thankfully interchangeable.

All I can say with certainty is that the closers work.

You being in Germany, there is an option for you that you probably should consider.  There is a German seller offering take-off MT5e sets.  I have corresponded with him as he does not offer a manufacturer part number so we can tell which model he is offering.  My German is extremely rusty but I can tell he is offering the N0 versions which apparently are the closers, based on a few ads from sellers that I have researched.  Magura is silent on the 'N0' vs. 'NC' designations some vendors use.  I corresponded with the seller:

My Question:
"Are these the 'Closer' version? Hard for me to confirm with the information I can find on the web that 'NO = closer. Magura part # for 'closer' type is 2700984."

the Seller's answer:
"I trade with remainders of the company CUBE Germany. These brakes were installed on speed bikes 45 km / h. The brake interrupts the circuit and turns on a tail light.
I have sold about 12 sets of gas with this description so far. The customers had nothing to complain about"

Obviously we have a bit of a language barrier, and I think he does not post the part number or directly answer the question because the nature of his business means he doesn't know the answer.   So I don't blame him for the indirect response.


It may very well be that both versions work.  I can only say with certainty that closers work since I own a set.  I would save about US$50 by buying one of the two sets available on EBay right now, but if it doesn't work out I have to send them back to Germany.  For that extra US$50 I can buy a set of brakes I know work, from a certified Magura dealer, and I will receive them in about three days.  So I will stick to what I know.

Hey All, recently a good friend of mine did a complete hydraulic brake upgrade to my Sondors. But, but, but what about the e-brake switches you might ask. Well that is the really cool part. Ther is a new product on the market called the TripWire that is for this exact problem. And they have a new model that is plug-n-play for the Sondors. Anyway, I encouraged him to do a walk-through video for our DIY crowd...and he did a great detailed one and put it up on YouTube. On my project he installed Formula brakes with 203mm discs, including the TripWires which work perfectly. The difference in braking power is fantastic. But the best part is the FEEL. I now do all my stopping with one finger on the levers. Plus they look great! Here is the link to the video:

Enjoy.ave a new

      Hey folks that are patiently, or impatiently, awaiting a shipping notice or bike, please read this. Based on our experience with this since 2015, here is what you can expect:  PLUS, the Pandemic has a huge affect on deliveries with overcapacity UPS capabilities.  
      As containers arrive in LA, UPS take possession and gets them processed through customs. There are hundreds of bikes per container, and probably a dozen containers.  As each container is opened, UPS will mark them as received and you may get a notice with an expected delivery date (either from UPS or Sondors). This does not necessarily mean that it is on a truck yet or has left the facility The bikes are shipped by truck, not air. Once it leaves LA you may not get any update for days as the truck works it's way to your regional or local hub where it will be offloaded and scanned again. Not getting an update for a few days is normal. You will sometimes get a planned delivery notice once it gets to your local UPS. However, sometimes it just shows on your doorstep. Sometimes it shows up on your doorstep when the tracking shows that it's still in LA. It's quite inconsistent, and nobody should panic. If you get a notice, be patient. It can take more than 2 weeks to get to you depending on how fast they empty the containers and when they find space in a truck, how long the drive is, etc. Signing up for UPS My Choice might give you more info, but sometimes not. Whatever you do, don't start bombarding Sondors with emails about "where is my bike" yet. They have probably opened 1 of a dozen containers so far and are working through things over the next couple of weeks We all know there's a huge shipment of bikes coming. Thousands of bikes. I can feel the excitement, or maybe it's just me lol. But anyway I can feel the pressure building. We don't mind you posting your delivery notice, but please don't post your tracking number. Just black that part out, and you're good to go. You don't want anyone the be able to reroute your delivery to my house do you? Moderators will delete all posts we see with tracking numbers.

      My lcd has just died on my Fold sport from water damage I'm quite sure so this is my perfect opportunity to upgrade I have been looking at the 750w bafang rear hub motor and they say it will lace in 350w motor no problem but I have the 250w bafang rear hub motor. Will it fit? But first I want too upgrade the sondors lcd to the ktc3 25 amp and 25 amp controller and will wait till sondors have the 48v 14 amp available in Europe  until i upgrade the motor as the 38v 8.8amp battery won't be powerful enough. Any suggestions or problems with my plan I would appreciate feed back

      Hello everyone, I currently have an Original Sondors Fat Tire bike from 2016 (I believe).  I purchased it from a friend who had performed some upgrades to it.
      As the bike sits today:
      Luna Storm 48v 20ah Battery Controller Model KT36/48ZWSRMD-SLSLD02 Rated for DC 36v or 48v, Rated current 12A Maximum current 25+-1A (Assuming this is from Luna as well) Original Motor Bafang RMG06 36v 350W(10) 26-1-1508195560-6 LCD Luna LCD Dashboard for Sondors KT-LCD3 Took the bike out for a ride the other day after it had been sitting in the garage for about a month and received a motor hall connection error on my LCD screen. Tried the usual unplugging the connection under the chainstay and making sure I had charged the battery. I'm wondering if I am able to replace the cable coming out of my motor (if that is the culprit) or if I need to replace the motor altogether. If that is the case, would anyone recommend I upgrade to a 48v motor? Would it make a difference/ work with my existing upgrades? I'm new to the forum and Ebike scene in general so I appreciate any help. Thanks!

      SONDORS X arrived on January 7, 2019. 
      Living in Southwest Florida has made it easy for me to ride every other day.  I am recovering from a bone on bone knee with a  damaged  medial collateral ligament. 
      After a full year of daily PEMF treatments and two Prolotherapy injections, my Prolotherapy  doctor recommended that I start exercising using a bicycle to stimulate the natural lubricant within my recovering knee joint. I started exercising with a standard road bike, but  was not able to “Spin” with minimal effort as instructed.  I own a 2010 electric recumbent trike, but is it is next to impossible to get in and out of a bike several inches off the ground.   I recall seeing the SONDORS advertised several years ago and decided on the SONDORS “X”.  I use the thumb switch to move the Fat Tire “X” up to 16+ miles per hour, then put the bike into 7th  gear and move the pedal assist to  Number 3, this allows me to Spin at the optimal level, without causing stress on my knees.  I started with five minutes the first week and I have added five minutes per week, I am now at 20 minutes, and this technique has allowed me to build muscle riding it every other day. I have been able to move the pedal assist down to number 2, my goal is to ride on  Fort  Myers Beach after I have built enough muscle in my legs. My target for the beach is early March!
      My SONDORS X is a very well-built fat tire bike and has been the perfect platform for my recovery!  I don’t see myself going back to my electric trike or the road bike, the sign on my front lawn, “BIKES FOR SALE”
      Thank you SONDORS!
      P.S., Super easy to accessorize
