Servicing a Bosch Gen 2 Centerdrive Electric Bike Motor - Inside of a Bosch Mid-Drive
Вставка
- Опубліковано 21 лис 2014
- In this video a certified Bosch technician removes the second generation mid-drive motor from a Haibike Xduro RX electric bike. To complete this service you will need a lock ring tool (with a half inch drive and adapter) as well as a chain whip and T15 torx driver. The Bosch system can use three cog sizes including 20 tooth for small wheel and 18 or 15 tooth for a mountain bike wheel. The cogs are build by each manufacturer and the Haibike cog has a chain guide built in. The exterior plastic casing of the motor is mainly cosmetic but it does serve as a skid plate as well. This service would be done to install a light kit, deal with a speed sensor issue or replace the entire Centerdrive. From front to back on the left side of the motor are the HMI (Human Machine Interface) Cable, Headlight and Rear light Cable, Speed Sensor Cable and Power Cable. The motor itself weighs ~5.5 lbs. The Bosch Powerpack 400 weighs ~8.8 pounds. Bolts inside are torqued down at ~30 Nm. The new Bosch CX motor weighs 200 grams less and will not require a plastic cover so it will appear smaller visually and allow more clearance for suspension travel.

The lock ring tool is called a spanner socket or spanner wrench and is used in removing the ring for a part on a Sikorsky helicopter rotor head. It was designed in the 1960s.
I love my Electric bike
Sir I want Bosch electric conversion kit... please give information
I have a Cube New Trail with the new CX motor but had a Click, squeak from the unit and need to remove the pedal arm and left cover and re-torque the bolts and screws, they were somewhat loose.
solved the problem. I would suggest replacing the nylon lock nut if they become loose, they are cheap and easy to find.
I assume that I have similar problem in my Haibike. The light squeak appealed after every rain I was ride a bike. For now it sounds like one or more screws loosed little more and it has changed into constant squeak, no matter is a rainy day or not. That must be definitely the chassis bolt that holds motor to frame of bike.
Anyway I have to order few tools to fix it up, like a Crank puller and Bosh's 8 tooth locking.
It's also good to make a small service by the occasion and check all motor bearings same as put new Bosh Grease for main plastic crank wheel and change some washers for brand new.
It all might be a little pricey but once I get all tools and more grease, I'm more independent from any bike services and can do any maintenance for my own than pay my money every time I need a service to someone else.
@@MrProminister I found the problem for my Nu-Trail’
It was the bearings in the rear hub. The noise only came when pedaling not freewheeling.
It wasn’t the motor. Bearings are cheap and easy to replace before taking motor apart. The bearings that were bad where the ones in the free hub.

Thanks for your answer mate.
@Brian Woźniak
Thanks for advice buddy.
I will try to get all the tools I need to open the drive unit and diagnose all bearing conditions by the way.
Thanks for the vid though...informative rather than the usual hiding everything from the customer.
Thanks for the upload. Is there a torque setting for the motor mounting bolts?
How often do mid-drive motors need to be serviced or repaired?
Do you know of any drives that have had to be replaced, due to failure of breakdown? Thanks for sharing the video ;0)
It’s come a long way..
Vari nice
Nice
what size are the bolts and nylocs - so I can order Titanium ones.
Thank s
where may i buy this motor and what is the speed of motor
hola saben si el motor performace cx año 2019 podemos tener acceso al motor para modificar los perfiles de ayuda como si los tiene shimano es sus motores. o si el nuevo display que hay de boch el kios lo puede hacer, gracias
My Best e bike
It's a council job! 1 man working and another 5 stood watching..
hola tengo una bici electrica con motor boch performace cx, en concreto una mondraker prime 2019, la cuestion es, este motor no hay ningguna aplicacion que pueda tocar los parametro y que tenga opciones con el smarfone , como otras marca de la competencia, mi display es el purion , no se si con los otro display se pueda confifurar el motor y sus perfiles, gracias
If the Bosch patent is open , I wish someone can built a frame with an allready lower frame arc ready to receive the bosch unit . A conventional bb taking place of the open space meanwhile . Bosch should see it as an investment while aging people will buy the driving unity separately later in their life .
My Gen 1 Active line just went back to the dealer for some work. I've just noticed the outer plastic housing can flex, so if you squeeze the top of it, it squashes in. Can you tell me if thats normal, to be able to squeeze the plastic housing and have it flex allot. It does it at the top, but not the bottom. Thanks!!
The plastic cover is intended to have some flex, it can protect the motor if you hit it or something. It's like a bumper on a car in some ways.
i just got my haibike out from storage of 2 years (dry ) only ever did 187 miles , so didnt expect an issue but the pedals are just spinning , any idea how to fix this issue ??
interesting,,, do the motors themselves need any service work or are they good for a few thousand miles ?....then say bin them
They are good for far longer than that.Many owners ride several hundred miles in a week. On the other hand, many bikes just sit. I am unsure which is more streneous on the bike though.
a question that although it seems obvious is not clear to me. Is this an electric bicycle? ... how is your charging system? ... and when does the battery charge last?
para bens por mas pó andar na chuva
Omg cut a old tube and pop some holes in it where the bolts go and cut off the excess do deal 30 40$ part made out of garbage lol gotta love those extras
can you tell if there are any differences of mounting btw Active/Performance/CX, screw or placement maybe ?
I have the opportunity to buy a CX to replace my Active,
with your video it seems very plug and play, but with a 1000$ motor i d prefer to be sure of what I do ...
thanks
The mounting is the same, but keep in mind you really need to program the motor to the gearing and wheel size. The original manufacturer is the only one that has ability to program a motor on this level.
Que precio tiene ese motor.
The guy was a bit flakey when asked when a bike shop do this? He rushed out " a speed sensor issue" does it have speed sensor issues then ??
Como faço para adiquir uma dessa ; e quanto é o valor?
He asked a tough question of how much is 200grams.
Hi, I have a Bosch Performance Line CX, and a few days ago it began to make a noise, mostly on emtb o turbo mode but only at climbing.... Similar to a coffee grinder. How can I know the kind of bearings or kit I need to replace? Thanks a lot
Hi Andres. Maybe you can just lock for loose bolts, take the covers off and check everything.
@@tigattac thanks, I will check everything in a few days. Maybe could be some bearings? Do you have experience with this?
@@andresmartinez1237 I have a Bosch Active, but I have not opened it yet. But usually it is possible to sort these things out, and bearings can be greased up again. I am locking for more power, thinking of buying a chip-tuning kit, but they are expensive.
Thank you, I enjoyed this video, Can newer Bosch power units be retrofitted into existing mid-drive bikes?
You all prolly dont give a shit but does someone know of a trick to get back into an Instagram account??
I was stupid forgot the login password. I would appreciate any help you can offer me
@Enoch Josiah Instablaster :)
@Thaddeus Emory Thanks for your reply. I got to the site through google and Im trying it out atm.
Seems to take quite some time so I will reply here later when my account password hopefully is recovered.
@Thaddeus Emory it worked and I now got access to my account again. Im so happy!
Thank you so much, you saved my ass !
@Enoch Josiah You are welcome :D
where is the maintenance part? all what shown is motor removal
This is the 90's man. No motor maintenance, just remove and replace...hoping for warranty repair all the while.
"The new Bosch CX motor weighs 2 grams less ..." That should be *200 grams less* - or 0.44 lbs. I learned that these Bosch units are basically "Electronic Power Steering" units that are used in cars, trucks, ATV's and tractors. I am still hoping for more powerful motor units, and the loss of derailleur's all together. Derailleurs are fragile, and extremely succeptable to trail damage. Hub motors look like the way to go for severe trail duty. JMO.
Wait. This is what Bosch offers. I this is a specially designed unit for bicycles and are intentionally limited to low wattage for liability and/or legal reasons. You need to look elsewhere for all you describe. There are dozens of units without deraiileurs available...just not here. ALSO...he does state 200 grams...not 2 grams as you indicate.

Hub motor also negatively affects the sprung to unsprung mass ratio, hence degrades the performance of the suspension - it will increase the unsprung mass in the rear at least 2 times, it's a huge difference! Unless the frame of the bike is very heavy, there's no use of hub motors in MTB's.
Why does he not use a Bosch impact driver to disassemble the motor? Does he not work for Bosch?
Yea gotta be top comment over here ...
je voudrait savoir le prix du vélo élèctrique
Does anyone know what kind of motor bosch uses? Is it a brushless dc motor?
It is a brushless DC motor. It originated as a power steering motor for cars.
Help my Raleigh motus with only 400 miles from new but out of warranty is showing 531 error code and Motor will not work.according to the dealer ,Bosch analysis says the motor has lost all info I including wheel size and cannot be recovered and this means a new motor. I do not have £700 plus and I don't know what to do. The bike has had very light use by my wife and it worked fine one day but not the next.
wat is de snelheid van dezen bike

Is that an independent service place, or is it affiliated with one of ebike companies?
This was shot on location at Currie Technologies headquarters in Simi Valley, California two weeks ago (mid November 2015). Currie is now owned by Accell Group and they carry Haibike so that's what he was working on in the video :)
ElectricBikeReview.com Thanks for the info.
It's nice seeing certified folks. I assume Bosch mid drives will be getting bigger next year.
***** Oh, what I meant by bigger was "getting bigger deal" as more of Bosch systems arrive in USA soon.
The next version, meaning, 3rd generation Bosch mid drive?
GiantEnemyCrab Gotcha! I think it will arrive in the US around 2016 and might include their color display with GPS and stuff. In the mean time, Shimano has some cool ebike systems and so does Yamaha... Lots to cover out there!
sounds exciting, thanks for sharing the info
The cameraman has to hold the camera steady and sharp, it seems he is giving the plants water. I have seen nothing. Loosen the bolts is easy for everyone. I want to have a look inside the motor.
"INSIDE" of a Bosch motor. Thanks. This was a 13 minute video of wasting my time with watching, how you remove some bolts and dont do anything else.
So...buy one and tear it apart. Make a video of your own and let us know when it is posted. Nobody wants you to tear into this motor. It will take a free thinker to come up with such a video. Happy trails!

iphone6 camera?
Hi Zamin, I was actually using a GoPro Hero 3+ Black. I realize it gets fuzzy during the close up parts... kind of a bummer, I guess it doesn't auto-adjust once you start filming?
All Bike Update GoPro hero 3+ is good one, i do follow all your electric bike review.. just saw the one man was filming also next to you on iphone6, so just interested..
All Bike Update i have Golden Motor, MAgic Pie 3 with 1500watt and its very powerfull enough for me, just need better battery :) have you review ever this product?
Zamin Huseynov I've heard of that motor but never come across one in person. Would love to review it sometime... which bike did you install it on? Which battery did you go for?
All Bike Update it it Cross Cycle, named "BeOne" old brand but durable brand, i have photos in facebook facebook.com/photo.php?fbid=827589817265550&set=a.827588643932334.1073741865.100000436198414&type=3&theater battery is 48v 10ah

Available in amazon at low price.
Today ebike, tomoro emotorcycle. The motor and chassis looks heavy.
the new CX drive has 15nm more torque in turbo mode,probably a good thing if your a fat mess,and need every last bit of humph,it’ll waste your battery quicker.
How much this bike brother.
This bike is no longer available, but you can see newer versions like the Haibike Fullseven, which would be very similar.
your never service the bosh motor
DT Swiss jep
Really simple using an old power steering motor, massively over priced for what it is. About time they put some proper development in than repacking old technology.
Or, another take is that Bosch spends millions on R&D on that power steering motor, making it light, efficient, and strong. The automotive-grade product out of Germany is a great starting point for this, their customized e-bike adaptation of the steering motor.
Shaky camera, difficult to watch. Use a tripod!
Bosch certified...really....took him a while to figure out lockring loosening direction.
Might be a little distracted with all the onlookers, I know I would be.
Fantastic weaponry...until you need a replacement battery...then it all comes unglued. Have you seen the price of replacements!500 to 1000 charge cycles? sounds like a decent lifespan until you factor in garbage such as dead (or 'dysfunctional' cells ) water ingress, 'deep' discharge....etc etc.Until that price sorts itself out .....seven HUNDRED Euros/ Bucks ?...I'm out.
Probably not something you do every day so you don't got much practice at it in the first place
Change the title of the video. Bosch motor removal

The most concerning thing is he doesn't know how much 200 grams is i wouldn't let these work on my ebike
Servicing a Bosch mid drive
Step 1- throw in trash
Step 2 - buy a BBSHD and be happy
I want a bbshd but UK law is retarded 250 watt only, and they want less people in car's 250 watt is pointless.
I heard that Bosh is for old ladies. Panasonic is better
+kamechas No, it was HITACHI.

Waste of time. Title is a lie.
Nice simple and horribly expensive. Compared to conversion kits. A nice underpowered overpriced ebike with poor parts access.
As compared with many conversion kits I'd describe the Bosch Gen 2 system as reliable, responsive and legal.
+ElectricBikeReview.com at 250 watts, reliable is a different thing to be compared to 1000w.
It's too complicated!
so stupid that they didn't just use a hubmotor..
There are so many hub motors on the market already, I like the variety that this premium mid-drive motor brings to the space. If you prefer a quieter motor or want regeneration then a hub like the Go SwissDrive used on the Specialized Turbo can be great: electricbikereview.com/specialized/turbo-s/ or the Ultra Motor on the ST2 is also great: electricbikereview.com/stromer/st2/
Was a little apprehensive when buying this with the few negative reviews on here, but this was exactly the kind of bike I was looking for. ua-cam.com/users/postUgkxn_jUDSlprMIeubd9rHdEAnv59nKfjcKv I plan to ride it on paved roadways and trails, and wanted a "Grocery Getter" so to speak. After receiving it (without any damage), I had it out of the box, and fully assembled in about 30 minutes. I did not have to look at the manual, and I'm glad because I did look at it after I got it together, and it looks like it's a manual for several different styles. I did have to adjust the breaks and gear shifters, but that's been my experience with every bike I've owned. There was one review in particular that made me nervous, saying it was not meant for someone 6'4", it was too short. Well I'm 6'5" (230lbs) with a 36" inseam, and can tell you this bike fits perfectly, granted the seat is in it's highest safe position. I've only had it for 3 days so far, and if things change I will update my review, but I put 26 miles on it so far, and it rides like a dream. Very comfortable seating position. The front suspension is good for the occasional rock or bump you hit on asphalt, but this bike is not made to be taken off road, and I'm OK with that. I was particularly happy to see the wheels were trued perfectly. I was expecting to have to take them in and have them trued at a local bike shop, as I've had to do with all my past bike purchases, but in this case they were already in great shape. For the money, this is an awesome bike.
Nice
