- This is a simple step by step walkthrough on how to replace a belt on any brose ebike motor. All parts and tools shown in the video are available on our site. ebikemotorrepair.com/parts-id...
Awesome. I just purchased a Ride1Up Prodigy XR. All of the bicycle parts are off the shelf items that I can maintain. The Brose motor had me worried though about repair after warranty. I can do this belt change. For anything else on this motor, I can just send it to you guys.
This video might seem scary but in all honesty Brose is one of my favorites because it is a very well performing motor in all areas. Quiet, intuitive, powerful... Sure send it on over when it gives you trouble.
Thanks for the videos! Was able to fix my turbo vado with your belt kit with very little effort. Really appreciate all the detail you included, made the overall job very easy. I think the hardest part was putting the cowling back onto the bike :)
Awesome feedback and thanks so much. Glad it helped. Hopefully you bought the belt kit from us.Let us know if you ever end up needing service on the unit. we can help. Oh tell me about it with the plastic! We pull our hair out because of those things! And forget about it if you accidentally loose or strip one of the bolts! sometimes hard to find replacements.
I would use the petroleum jelly on the shaft seal too. I use it on any rubber seal or gasket to keep them elastic and pliable.
Thanks for the great videos Michael. I have 1,200 miles on my 2022 Turbo Levo Gen 3. The motor seems to run like new. I live in Colorado and have have been able to keep it away from puddles and creek crossings, so the worst it's subject to is dirt and dust. When would you recommend preventative maintenance?
Good for you, Steve. Colorado is a pretty dreamy state for riding. I would say some of our customer base like to have an extra motor that they swap out and have overhauled every year and just make sure to stay ahead of any breakage. But most of our customers fall into a category where we just kind of fix it when things start breaking.
Great video, thanks. Will be shopping on website. Did not see that specific torque screwdriver. That one is adjustable?
Sorry for delayed response. No the torque wrench we sell is set specifically at that quarter Newton meter
Hey,very nice video.You think you can do one with a panasonic motor?thanks,Levi
Hey Levi thanks for your comment. Actually, Panasonic are way simpler motors than the Brose. They’re very basic inside. Almost done necessary to do a video. However, if you are having problems with a Panasonic this is something that we offer Repair services for. Check out our homepage and you can open a service ticket and send the motor to us. Or feel free to message us with your problem and we can try and help you troubleshoot. www.ebikemotorrepair.com
Hi Michael, i changed my first belt thanks to you , great video. I did inspect the planetary gears, looks good. Should i add any grease ? Would Molykote pg-75 be the one to use ? Thanks again
Grease in the planetary gears is unnecessary. But yes if you need it as in if you wiped it out or anything then the pg-75 would be appropriate.
Unnecessary meaning the grease already there should suffice. No extra needed.
Hello. First off all I want to thank you for your channel and content. Im considering to replace the belt myself since im tight on money. But if i woudnt. Do you recommend anyone in Belgium/The Netherlands?
Thanks for the compliment. Here’s a list of our worldwide partners. I would advise finding whoever is closest to you and work with them. They’re part of the family. ebikemotorrepair.com/world-wide-partners/
This is awesome 👍 ...are the 2.2 motors any different?
there are 2 main differences in the brose legacy. All aluminum models (S/T) are mainly the same and all magnesium models (S-Mag) are mainly the same as well. The only differences between those models are the improvements they made on belts and software/firmware. But mechanically they are all basically identical. Also the only main difference between all aluminum models and all S-Mag models are the cases and therefore gaskets are different between those models.
Is the screw on the top the only thing that sets the tension on the screw or is there a spring aswell? I'd say if that screw all that tensions it regularly setting it would help the belt last much longer?
The set screw is indeed the only thing that sets the tension on the belt. Resetting it might actually cause some issues because both from the factory, and after an overhaul, there is locked type, applied to the set screw, which keeps it in place. Readjusting it would require you to clean the threads and apply new Loctite and would likely get you within such a small fraction of meter difference that would be negligible. Plus belts don’t typically fail from wearing down from fatigue. They just eventually break or fall apart. They don’t necessarily get smaller in the overall material.
Da es immer wieder Probleme mit gerissenen Riemen gibt meine Frage dazu. Wäre es nicht sinnvoll wenn der Riemenspanner mit einer Feder versehen wäre um eine gleichmäßige Spannung des Riemens zu erreichen ?
Hi Micheal, when i opened my motor case, the whole section with the large belt gear and bearing came with it. I think it's still attached to the pedal sprocket and i'm not sure how to separate those. Any tips?
Hey buddy I think we can help you. Send me some pictures via email. service@ebikemotorrepair.com
Hello i have bulls bike woth brose motor, and have bloks 14d display but cant turn on the bike . Can u tell me how i know should i buy new display or my motor doesnt work because i bought bike from another person and not from dealership. My mechanic guy can not tell me whats the problem. Thank you.
Hey, I’m sure we can help you with this. Let’s communicate through email and maybe you can send us a few pictures of your motor and we can explore and more detail a good repair strategy for you. info@eBikemotorrepair.com
Where can I order one of your belt kits and the torque wrench? I’ve got a busted belt on my 2020 levo and am told it’s out of warranty and need to buy a new one for $1k (not cool!)
Your best bet is to send it in for service. but if you want to handle the repair yourself feel free to jump on a call with us T-F 10-6 and Sat 11-3 (CST) to discuss options. Otherwise check out the site www.ebikemotorrepair.com. Our phone is text friendly too. 615-656-5457
@@ebikemotorrepair thanks I appreciate that, but I’m very capable of doing the repair- just need parts. I checked the website and the belt kit I need (Brose s-mag) shows it’s on back order. Any idea when you guys will have stock or would be able to ship? Thanks again!

How much are reliable those Brose motors? I saw few videos with tooth belt and tensioner problem. Is that belt kind a week point of this motor? I'm interested for buying one E bike with Brose model T motor, I like his power and torque but what after the warranty? A new motor cost several hundred Euros and repair is also expensive here in Deutschland...any advice? Tnx and keep rocking!
I have several bikes and brose is in one. Great motor worth the maintenance. If upgraded and sealed they last a long time. We have a partner in Germany. Happy to share the information with you for when your motor is out of warranty
@@ebikemotorrepair Thanks for replay. My biggest fear is because I love to ride big far tours and what if in one tour I have motor malfunction...that's a problem because you are 50 or 60 km far from home. Anyway, hope soon can buy E bike (Rockrider e-St 900) and start new chepter in bike experience. Cheers
@@TheBogisha well it’s certainly happened to me like that. The ride just becomes a hike I suppose 🙃
@@ebikemotorrepair e Bikes - so much happiness and so much worries. Like a car.
Is there big difference between Brose T and S motors? I'm asking because recently found somewhere info that belt problem has only S model and the main reason is bigger torque and much more extreme conditions with those motors. Is there any true about this?
@@TheBogisha yes they put some weaker belts in earlier models. the new carbon fiber belts are amazing though.
does the 2021 s mag motor come with cf belt?
Sorry just seeing this. That’s a blurry timeline but I know they began manufacturing some of them in late 21 and mainly 22 with carbon and polymer. I’m still not completely clear about exactly when those started making their way onto showroom floors. There’s usually a bit of lag time between motor manufacturers date and when they make it into bikes.
how often you have to replace the belt on Brose? the standard one or reinforced
It’s pretty subjective honestly. Depends on rider, riding conditions, etc. Plus there’s always minor little differences in manufacturing process that can affect about life. But, all of that aside a typical range of life on the belt is about 3000 miles plus or -500 miles. However, we’ve seen some customers go as much as 10,000 miles. We also have some customers that have Bros mounted on passenger and cargo bikes that only see about 1500 miles. To answer your question about the difference between the older belts and the newer belts we tend to see between 30 and 50% more life out of the carbon fiber belts.
@@ebikemotorrepair thank you, as one of the fellow mentioned that it must be replaced every 1000 miles
@@VovanCBR I’d say that’s a bit excessive. My opinion is fix when they break. But I suppose if you want to buy a belt kit to have on hand it would be smart. However keep this in mind… belts don’t slip.. so if you ever experience this it’s going to need to bearing replaced which will likely be a good thing to overhaul at that point. We have your back either way. Also belts and clutch bearings have approximately similar lifespan. Let me know if you have any questions. Thanks for engaging.
Isit .2nm torque for set screw?
Yeah pretty crazy right? Actually specs 0.2 through about .27
We sell them on our website if you need one. It’s kind of a hard tool to find. Not a common shop tool.
can you made video about open and close the oder side pls, i open it and now have no working drive, before i open it wass working
No need for a video, you simply unplugged the pickup ring sensor. it is really hard maybe impossible to plug back in with completely disassembling the motor. If you are in the US We would strongly advise you send it to us and let us p[lug it back in for you. Please fill out a service ticket before sending anything to us: ebikemotorrepair.com/repair-overhaul-service/

What type of bel is?HTD?
Brose OEM carbon fiber upgraded belt from the factory.
My SMag doesn’t have that tensioner bolt
Yeah it does but it's hiding under a small white sticker on the bottom of the case near the case cover.
Hallo, ich möchte die Riemenspannschraube nicht anfassen, ich werde den Riemen wechseln und das war's. Was wird dabei herauskommen?
Ich verwende „Übersetzen“, also verzeihen Sie, wenn es nicht gut ist. Beim Riemenwechsel sollten Sie die Spannschraube lösen. Setzen Sie dann die Schraube für den neuen Riemen wieder ein. Sehr wichtig.
Ок.The fact is that to measure tension you need a torque screwdriver, and it costs 100 euros for a range of 0-20 Nm. 12:04 I do not consider fixed ones at 0.2Hm.. And now I’m experimenting and using a similar belt, only 1 mm narrower, but it costs only 12 euros.405-5M-15 GATES ®😊

Cant move my bike backwards. That would suggest major damage right. This is after I changed my belt.
Most likely, you may have damage to the planetary gear. If you change the belt yourself while you have the belt out, you are able to inspect the planetary gears. If you haven’t already done, so try and take it back apart and see if you can remove the black plastic shield, that covers the gear cluster and see if you have damage.
@@ebikemotorrepair ok, but couldnt it be problem with the gears in the freewheel of the back wheel also?
@@tekoppentekoppen761 not sure hard to say without having the bike or motor in front of me.
Hello may be you can help me with advice I changed a belt on my brose s mag(tighten it properly with 0.2nm) and after ~30km under a big load it starts to produce a squeaking noise.
I tried to retighten it couple of times with the same result (using blue past)
Did anyone figure out how solve it?
I bought 2 spare belts, should I try them? Here is the video Belt noise.
All internals looks ok
You can check video in my UA-cam shorts
sorry but somehow we overlooked this comment originally. The issue is likely the clutch bearing in the belt pulley. Belts don't "slip." They just break usually. But the clutch bearing in the belt pulley will definitely slip when it is failing or failed.
I lost the piece you need a special tool to open. That holds the crown.
I’m not exactly sure what you’re referring to but I think you mean the lock ring nut? The part that holds the spider and sprocket on? Also it might be best to switch to an email thread to help expedite getting a replacement for whatever it is you’re missing. michael.damico@eBikemotorrepair.com
im totally put off on buying any bike with these motors now........ stretchbolts and rediculous torque numbers . 1 -5 nm ffs my toiletlid is wrenched down more firmly than that.
and god knows why they need to use a belt when a geared setup is going to last forever longer.
i honestly think these ebike guys havent got a clue.
or le gouverment ( scumbags ) don't allow them to make something intresting
🤣🤣 I hear ya! We repair tons of brose motors and they are definitely prone to failure. I ride anything with 2 wheels myself so don’t discriminate. But when my ebike works it’s a ton of fun. I’m of the opinion that the current industry is evolving and I’m sure we’ll see improvements. But damn… they are a blast! I’m a former MX racer too. I’m used to wrecking ICE drives. So familiar Territory for me.
You’re correct though… gear drives fail far less than the brose belt drive. But I will tell you what.. that motor is super intuitive compared to all the gear driven models. Like Bosch, Yamaha, etc..
That torque spec you referred to is important because too much torque and you destroy the planetary gear cluster (nylon) too loose and you destroy the belt. So that’s the purpose at least.
If you ever decide to get an ebike the Bosch is pretty on point. We service all of them and aren’t married to any particular motor but the industry definitely has tons of room to evolve.
speaking of bosch is there a way to retrofit a bosch or any other e bike motor to a bike that came with brose? why hasnt anyone tried this? I would just dump this brose pos and use something far more reliable.
Thx a lot 4 the video man 😊👍🤝
