This £750 eBike repair could have been avoided

[@yru435]

If Bosch is not going to support their motors, they ought to have a 'rebuild/refurb' service that would allow people to avoid throwing away their injured motors.

[@armedcannon]

They do both of those things, as is mentioned in this video. What they don't do is sell drive units to end users, only to OEMs.

[@tombowman4489]

Bosch are actually one of if not the best for this. They even sell a DIY service kit for the first two gens of their motors. Which is the left half of the motor for about £100 I think it was. Bought one and fitted it on a bike of mine. Not childs play to fit but certainly doable for most. Can't praise Bosch enough for this type of thing.

[@gregmossed]

​@@tombowman4489 how is servicing it yourself? I've done lots of work on dirtbikes and cars and this all looks like stuff I could do, but I'm not sure if I'll run in to dead ends trying to get a replacement bearing or something then have shops refuse to touch it if I've opened it

[@tombowman4489]

@@gregmossed it's a kit Bosch sell for the Gen 2(possibly gen 1 also). It comes with everything you need apart from the locking tool to open the motor. It's basically replacing the whole one side of the motor which includes a few gears and such. It needs to be done with quite methodically with a high level of hygiene and precision but overall was crazy difficult. There is a main drive cylinder they tell you not to handle but mine was rusty so needed a bit of love. They don't give you a new one of these but I've heard there is a company who makes titanium copies of them if you want to upgrade or yours is a bit worse for wear. Unfortunately, I do not think they make such a kit for the very latest Bosch motors though.

I had E-bike based on a Brose system. One day some bastard stole my computer aka control unit. After i got a replacement off the eBay it just popped error and refused to work. Same model of computer. For same motor etc. Just different serial number. Turns out Brose just decided to kill off any way to replace parts if the original got stolen or died. You must have matching serial numbers, else nothing would work. To fix this, you must send the whole system, including the battery, to an authorized service center. And since the new computer was purchased off ebay there's a chance your repair still won't be authorized by Brose. No more e-bikes for me. This is totally anti-consumer. We need to add e-bikes to right to repair bill.

I can't stand that companies serialize components. You can usually flash the firmware so that the serial number will match everything else, BUT that also usually requires their hardware and software to do. They probably do that to deter theft, but at the same time makes repairs challenging to do.

[@bigwave_dave8468]

The Bosch frame mounting system with that unusual flange makes it impossible to swap or repair with a different brand motor. Given that a Tongsheng ebike motor (about $300USD) *retails* for 1/3 the cost of the Bosch motor *wholesale* shop price and the fragile nature of the Bosch, the Bosch system seems designed to extract revenue from unsuspecting bikers and shops. With no mounting standard or cost control of spares, the system is not "repairable" except by extraordinary means they way you've done.

[@Xibalba28]

As a shop manager I struggle with these types of situations too. All in all I find it best to be completely honest and transparent with the customer about cost vs. value. That's exactly what you did here and the customer chose to repair their bike. Sometimes customers REALLY like their bikes and don't want to seek a replacement. Good job and amazing work!

Good point...if you have a bike that's a good fit why then take an expensive punt on a replacement.

[@JMJM75257]

If I were to work in a shop I'd suggest mid drive kits. That way if it goes wrong there is always the prospect of simply converting it back to a normal pedal bike.

[@tconnolly9820]

So almost 800 bucks for this repair plus a probable another few hundred for other repairs in the near future. Plus whatever the Trek shop charged for their somewhat half arsed efforts. I'm not sure what model that Cube is but let's say a brand new bike will cost around 3,500. This makes repair seem like good value. Ok, if she could get a decent second hand for less than a thousand then that would make sense. But you never actually know what you are buying second hand. It could be someone else's problems they're glad to get rid of that could cost another thousand to put right. Manufacturers really need to prevent water ingress so easily though. I had my last car for 8½ years. Bought it with 210,000 km on the clock. Put another 140,000 on it before the injectors went. Also the flywheel was wearing so another repair due shortly so I decided to move on. Not counting regular service and replacing tyres, brakes and regular parts that wear out, I spent less than 1,500 on repairs like a fuel pump and alternator and some other bits and pieces. E-bikes are ridiculously expensive to repair it seems. And I'm waiting on delivery of my first one next month.

[@jotham123]

@@tconnolly9820 100% agree. Further to your point, as an example I've got a cube that I commute on and I'm doing lots of adjustments to get it all fitted out just right for me and just run-in with all the weak bits replaced (rear wheel rebuilt, then freehub die,d which meant new hubs, then better quality fork parts, then pedals, light upgrade ..). If I had to drop a new motor in it, I would definitely and can imagine it's possible this customer is the same they found what works, replaced the weak parts and don't want the time, pain and costs associated with this process.

Commenting about your comment at 07:36. Apple did make some assemblies available at exorbitant prices to discourage repair and encourage buying a new one.

Bafang does actually provide replacement and repair parts, I just rebuilt a BBS02 for a customer all the bearings and seals were available for me as a US Bafang dealer.

Even their CAN BUS motors have good parts support (though using a C961 display for calibration of the UART controller on M series bafang motors is annoying). Vendors such as Green Bike Kit may be useful to you guys and any people out there with bafang motors. Bosch is relatively alone in the e bike space as far as big companies that don't provide enough motor repair parts.

I feel you with this one. In our bike shop we have had similar experiences with finding spares, repairing electronics and such. Sometimes the hardest part is trying to explain to the customer that their bike repair is going to out weight the value of bike. I've quoted up repairs on E bikes to customers and been sworn at for taking the piss and being a scam artist. We are not. We've broken down the quote exactly as you have, contacted suppliers for cost of parts or sourced things from Ebay and the like to fix Bafang bikes. There is a little bit of blissful ignorance with an elevated cost of repair with an Ebike with consumers and I don't think its there fault necessary. Sorry sounds ranty. The video was brilliant and some good education into Ebikes.

[@waysidetimes9226]

People's reaction to this is understandable. A lot of these bikes were less than $1k new, and not many customers I've talked to have any conception of how fixing things works. "It's a bike, how hard could it be", LOL. I come from automotive. Automotive techs make the same as bike mechs in my area. Auto repair labor rate starts at $125 an hour. IMO, not a chance your no-name e-bike is worth fixing unless the fix is an hour of labor and that much in parts. I see tons of these things 1-2 years old for $300-500.

Not saying they have to know how to do the work themselves, but checking for bearing play and other basic signs of mechanical soundness is not difficult.

As an electronic tech, I assure you that even if you got that PCB board working, it would most likely be intermittent at some point, and/or other problems would present. Remember, when dealing with FETs and (by solid state terms) high impedance circuits, intact copper board traces don't make or break the circuit function. *Leakage* does, and once road salts and acids have found their way in, the entire circuit is compromised. Technically, by business terms, you lost on fixing this. But overall, I think your operandi pays off. The owner will be back for service, and others, based on the PR you've invested in.

Utterly fascinating video, and horrific at the same time. I bought a Giant Xplore +2 the month before covid lock down no.1. It has been great fun and has enabled me to cycle far further than I would otherwise. 3,500 miles in 4 years. Whilst strong I have minimal stamina, due to loads of surgery, and sometimes totally depend on my bike to get me home. Two years ago I was caught in a major rainstorm and shortly afterwards my display started misting up and after 30 mins was totally unreadable. Shortly after that the motor went into limp mode. Shortly after that the system packed up altogether. I was out on a club ride and we were about 5 miles from our campsite. It was a nightmare to get back. 27kg + gear. Two days later at my LBC I was advised that the display, controller, and motor are not waterproof AT ALL. The display was totally bust, as was the controller. The. Bike was 1 week out of warranty. Because my LBC had regularly serviced it they managed to get Giant to contribute 50% of the parts cost. The parts took about 2 months to turn up. My 2 wheeled paper weight sat forlornly in the garage. I have since tried to upgrade my battery to a 650 (from 500wh). Nope. Can only do it if you have the following years model. Not happy. Recently I have been delving into motor compatiblility, backwards compatibility, manufacturer specific designs. My conclusion is that if my motor packs up the bike is heading for the tip. I shall revert to using my old but fabulous pure pedal bikes. I am not shelling out another £2,500+ to get conned by dodgy manufacturers. The only alternative may be when some Chinese manufacturer starts building ‘compatible’ motors for half the price. Like your customer it is important to me to properly repair wherever possible.

First motor was 2 weeks out of warranty with bearing noise and Bosch graciously honored the warranty and provided a new motor. This time not so lucky!

@stonehill27 My son has the tsdz2 500w version on his bike. Personally, I'm not too keen on them as I find them too flimsy. Everything is literally held together with circlips. The torque sensor works OK, but it's made of garbage and develops too much play on the axle and main gear. You can add 3 extra bearings to secure the axle a bit, 2 on the non-drive side, and 1 where the oil seal should be in the chainring on the drive side. I don't know if the newer B version is any better. I personally prefer the bafang as they're so reliable. My motors approaching 17000 miles, and I've done a full bearing replacement twice, minus the thrust bearings and needle bearings, and the motor still works like a dream.

[@kuchenblechmafiagmbh1381]

I don't want a eBike yet but got a Gudereit trekking with Pinion gearbox leased since a year now and because that gearbox is in the middle you could easily fit in a rear hub motor later and put the battery under the rack or into the frame triangle; Mahle (another car supplier like Bosch, Brose and Continental) does such a system but sadly doesn't seem to offer that as an upgrade kit ☹

[@martinault7863]

Had three motors under warranty from Bosch.Performance line bearings sell an outer seal to protect the bearing .Had no trouble for 3 years 2000 miles.👍

[@jankazimierzcybul-jl8zi]

The spares unavailability for the pre built ebikes is one of the reasons I keep using bafang bbs kits , you can find every spare part for them and easily repair as a home mechanic, the downside is the waiting time for the parts fortunately I didn’t have to replace anything yet in 8000 kms

[@BramBiesiekierski]

Option 4. Use a conversion mounting kit in order to fit a bafang m5/600 or m620. People make them for this exact reason

[@paullyons7825]

@BramBiesiekierski that’s definitely an option & something I’d look at, but as you’d need a conversion mount, bafang motor, battery & controller, so once fitted would it be much cheaper for a shop to supply than a slot in oem motor?

[@nay0r]

great work guys, this is a tough one if the bike was cosmetically in good condition it might have been worth it but this time it was borderline probably not worth doing. damn shame these big boy companies don't like us repairing stuff and would rather we throw stuff away and upgrade all of the time

[@bobbo9549]

Blimey An informative video but glad I’ve got a hub motor unit set up. Might not be as fancy but a lot simpler.

[@sportsrecoveryonline8802]

Nice vid, well explained and great to clearly see the customer kept informed of everything along the way. If this was my bike, regardless of the condition, I’d want to know all the options in order to make the decision 👍

[@chris_gb_]

Polini from Italy and Freeflow from Scotland designed their motors to be fully serviceable with replaceable parts, I think I'd take a close look at those if I was looking for an e-bike. Have you seen either of those in the Mapdec workshop? When it comes to servicing there's apparently not much to choose between Bosch, Brose, Shimano et al, i.e. the big players that dominate the OEM market, but it seems like the costs can get out of hand too easily. It's off putting to say the least :|

[@bradallen8643]

Always do what you did . . . try to fix, investigate options, replace parts if possible and available, if can't be fixed then buy new component but only if owner is happy with bike's performance and doesn't want to upgrade to latest tech or design

[@papap.8006]

Nice job and really think you are doing a great service for the e-bike community. Very nice!

[@SteveKimbo]

We can all agree less stuff needs to go to landfill. You've done the right thing, you gave the customer the options and happily she opted to repair the bike instead of slinging it away and buying new. I think it's extremely poor that the motor manufacturers don't supply full rebuild kits for these things. It stinks of profiteering that you're forced to buy a new motor. What we all need is for Hope to start making motors and supply every spare part for them for the next 20 years 🤣 Here's an idea, CNC plates which take a normal BB to convert scrapped e-bikes back to normal bikes!

[@Saints66]

Really enjoy these videos. It’s important to try and fix, not throw away. Surely companies can assist, by offering more spare parts. This will underpin longevity in the overall industry and potentially improve profitability, employment/training/innovation, down/up stream distribution, extended product life cycles….🙏

[@Mapdec]

Thank you. The only way it will change is if one company starts doing it and we all start buying it.

[@Thecrazyvaclav]

Always seems designers/engineers never thought that putting the motor right where it’s going to get drenched by the front wheel throwing water onto it when it rains was a bad idea, add in the motors don’t seem to be sealed that well, and then throw circuit boards in as well, it’s always going to end badly tbh

[@gibfear]

Hard to believe it was ridden to that state - we all ride stuff that might have a bit of an issue starting, but that must have been a mess for a long time!!

[@FIGHTTHECABLE]

Pinion MGU uses an oil bath, which is supposed to keep water out. Will see how well that goes for me.

[@JMJM75257]

This is exactly why i dont use bikes with integrated e bike motors. Instead i use mid drive kits. Like the bbs02' hd and recently the tongshen tsdz8. Especially for the bafang motors parts are plentiful and somewhat cheap. It does mean being open to your own diy repair but imo its part of it and not so difficult if you have decent bicycle building experience. Another thing i do is to spray exposed electrical areas inside the motors with conformal coating. The grease i use is mobil shc100 and i do tend to clean and regrease every year or so. So far ive had a bbs02 for 4years that yas over 10k miles with no issues other than a new plastic front case and a gasket or two upon reassembly. I use bosch cargo line daily also for work and have had issues with pawl slip on multiple motors in the past. Im not convinced bosch motors are all that great apart from the software side were they really have managed to make it feel seamless.

[@MarkSawtell]

I have a fulgur mula from berkshire cycles that has a polini motor which is totally serviceable and all parts available. I've owned all motors and have to say I went for it purely because if the support from polini but its actually a very good motor too.

[@IronHorsey3]

500th like even though I don't own any eBike but this was interesting with the lack of alternatives. Sadly, Bosch should have had a PCB you can buy for $50 but they won't allow you that option. You did the correct thing here as your choices were limited and the longer view was clearly replacement. Always impressed by the thought process.

[@paulhshudson]

I am all for fixing it, so I respect the owner's choice here. It's a steep cost though, especially when compared to car repairs I've had done. That motor is a lot of money.

[@lozetchells9164]

Wish I had you guys near me as my LBS! Thank you for the video, very informative. Bosch and Shimano are terrible for repairability, totally agree with that. Thankfully Brose/spesh motors seem to be a bit better supported with lots of spares and third party specialists. But I'm not sure I would give Apple any credit for repairability - they were forced to! Time for ebike motors to get the same regulations I think. Scrapping a bike because of the motor should never happen.

[@Mapdec]

Yes. Brose are a lot better.

[@noelmclean936]

Onya. I hope you & your company do well. Honest tradies are becoming hard to find. Noel, from Australia

[@PW-CreakySaddle]

i kept sending my old car to garage to keep getting fixed and spent more than it was worth at least three times to keep it going - and not scrap it. it is still in use today (by new owner) - over 250kmiles and 17years old. I would probably do same with a bike if i liked it, it was great when working and till cheaper than a new one.

[@robertanderson402]

thank you for being honest repair shop😊😊

[@Mapdec]

Our pleasure!

[@jmcbike]

I suspect that the motor controller could be replaced with an external generic motor controller with Bafang display, thumb throttle and PAS sensor. Bosch would not approve. With Bafang motors, even the internal motor controllers for the BBS-HD are readily available.

[@jasonjohnston6818]

PS just heard that Brose Motors are the best to repair, kudos on them for that!

[@jonburnell532]

I like the fact they went for a replacement part rather than a new bike. As you said, it didn't go to landfill, it will have been cheaper than a new bike, and most importantly they get to keep THEIR bike. If they have an attachment to the bike, the money isn't as much of a factor.

[@tonysadler5290]

Thd "e-bike Motor Centre" does a kit that includes upgraded seals, bearings and waterproofing for some motors, that effectively prevents water egress and, therefore saves bearings etc for ebike motors. However, it never ceases to amaze me how people abuse mechanical machines and continue damage parts without a care or realization of what they are doing! But then, I spent a good chunk of my life as a mechanic. The look of blankness to my question - did you not hear or feel that it wasn't running properly? Hats off to the owner for repairing it.. I have a much loved 2015 voodoo Bizango 29er, which I've spent way too much on, but I can't bear to see it go. I suppose as long as the frame hold up I'll keep with it - same goes for my 6yr old GT f/s, and my tourer, and my ebike! Humm, bit of a pattern here!

[@cli7148]

i believe bosche motors have a history of water ingress problems....just seen the vid about bangfang research lab...impressive

[@muratmustafa4532]

In that case replacing the motor with a new one seems to be the most logical choice. However, I was told that if worn out the wheel (i.e. the brake strip) on my Brompton I will need to buy a whole rear wheel including the internal hub gear which is the major cost of the rear wheel. When I asked if the rear hub could not be detached from the old wheel and put on the new wheel, so I would only buy the rim instead of the whole wheel, the answer was no. Later, I figured out that actually this could be done but some bikes shops finds it more profitable to just replace the whole wheel instead of salvaging the what can be salvaged due to the time they need to spend on it.

[@chrishodgson1968]

I would probably of got it fixed. They still have their bike and it has a new motor with 2 year warranty same as if they would’ve bought a new bike but cheaper. If you split it into two it’s only £300 per year, that’s not too bad.

[@stevoc123]

I think it’s just a lesson learned for everyone involved. Some people want to get every last penny out of the equipment before they’re even consider repairing. In this case, I think it’s just a case of you “don’t know what you don’t know” , and possibly trusting the previous shop to advise.

[@dogbreath6974]

Or the owner is hearing impaired.

[@armannvanhelden4884]

£70 labour! My local shop would probably have put an extra zero on that. Great video👍

[@bassw1758]

I've never seen that happen to a Bafang, Bosch should stick to making power drills

[@MS-bw7yt]

I never understand how people can ignore a mechanical problem for so long... it is like driving with a red engine waring light and then wondering why the car breaks down.

[@dominicbritt]

Speak to a car mechanic 🤣 . They see all sorts - people buy a new car, don’t service it at all and motor seizes after 4 years…

[@paulh6395]

In our car workshop we would not do this without the owner paying up front .I know two cases where the owner said go ahead and do the repairs then decided just to leave the car at the garage and go buy a new one because it was cheaper .Then it becomes the garages problem to deal with and lose money over.

[@arcoulant87]

I hope they bring it back in 12months for a service from you.

[@Monkey_slapping_keys]

Guessing they got a few years out of that, so not all bad. They will likely come back to you as well so will now get it fully checked as needed anyway, glad it wasn't wasted. As to the resale, it doesn't cover having a new motor with two-year warranty, which you generally cannot get second hand.

[@paulrimmer4848]

'Guessing they got a few years out of that' - not necessarily. I have a Trek e-bike which I have had serviced regularly by an approved dealer and the Bosch motor failed after just over two years and 5,000 miles on generally good surfaces.. I'm told that mechanically it is sound but the electronics have failed. As mentioned in the video, there is no replacement so it's a new motor for £700.

[@dereksaam2574]

I have the same Bosch motor on my ebike and it was helpful to learn a little about servicing it. I feel like Bosch intentionally obsolete their products, and provide minimal service options, the recent change to the "Smart System" the new plug does not allow any backward compatibility for the charger, battery, etc. which obsoletes everything I already have and they didn't provide any adapter or conversion options. This left me thinking my next ebike won't have anything made by Bosch on it.

[@SonnyDarvish]

I just had my first ebike problem over the weekend and it left me puzzled. Small issue that is overblown. After nearly 8000 km, apparently the sensor cable came loose off the motor. I tried re-attaching it, went for a ride, it showed soft fault instead of hard fault. Then I realized that I broke 1 of the 4 pins inside sensor port port. Fazua told me the only option is to sent the motor unit back to them and it'll cost around 90-130 €. The pin that broke off is probably 0.05 grams and it costs me that much? Even with premium postage, over 50 bucks to replace a modular port? 100% my responsibility to forget to follow the manual, but the design of the plug is deceptive and anyone could make the same mistake. The plug is round like a speaker jack (or 5520 DC port) and one can think that there are only a negative and positive nodes inside. Although, there are actually embossed arrows on both the cable and the plug, both are very faint and not colored (zero contrast). I noticed them after pin break off. One can easily make a squared-shape plug, hinting at the mechnic / user that there is a right way to connect it. Not only the product design is questionable, the choice of exclusive repair at their own workshop is baffling. Funny how they have "tiered system" dealers, certified and premium, but anything happens to the motor, they have to post it to Fazua HQ workshop.

[@caramba10]

I'm surprised China (who seem to copy everything) haven't already tapped into the replacement motor pcb market. There must be tons of dead motors out there that could be back in service with just a pcb swap out.

[@justyngorman1437]

I put my bike in the car and drove to Fordingbridge and got the Bosch repair centre there to have a look. My PCB was also toast due water ingress and unfortunately the motor was unsalvageable. So for less than £400 they fitted another reconditioned motor with new bearings, better water resistance and a guarantee. As a cycle shop, I would use these people on behalf of the customer knowing their warranty would cover you. I now have a gen 2 Bosch motor that goes well 😀

[@Mapdec]

What is the name of this place please?

[@f19ash]

Ebikemotorcentre?

[@PeterPutz82]

Great video, my ebaike is late for service, better get it in there asap!!

[@stevenaaus]

You're a dedicated man. Good vid.

[@MrRobl200]

As others have said, manufacturers should offer a refurb/exchange service kind of lik what you have for alternators/starter motors. Means a cheaper repair would be available that should still be supported by the manufacturer and easily offered by a dealer network.

[@knott4me561]

You can use a hg chain with linkglide but it has to be a 11spd chain

[@Vasyapetrov666]

This.

[@justclippedit1]

Never buying a mid motor e-bike again, 2 Shimano e6100 motor failures, one within 6 months, Shimano have no extended warranty on a replacement motor, absolute joke. Now using a rear hub motor e-bike with the sacrifice in torque but feel confident that this will last for years. Sealed, no water ingress concerns or bearing failures.

[@CoasterJames]

I’m not a lawyer, but you would hope the right to repair law would force Bosch to provide spares including spare pcb

[@stephensaines7100]

Not necessarily. If I produced what I considered to be a 'sealed unit'...why would I stand behind a warranty when someone (most likely a grease monkey) has compromised it, let alone with my name on the unit . Tell me folks, do you fix your own Integrated Circuits? (Actually it can be done in some instances, by absolute professionals who have a lab). The same applies to mechanical modules. I fully understand and agree with "Right to Service" legislation. But I also understand 'sealed units', and they've been "a thing" for a century.

[@noconcept5735]

​@@stephensaines7100in that case, they should have more faith in their product and provide a more substantial warranty on the sealed unit. Ebike users are either getting shafted by lack of reparability or lack of warranty.
