Imagine if we had the same problems with motorbikes and cars! And some ebikes cost more than many motorbikes! ☹️

Manufacturers promote all the tech but never state IP ratings, nor do they consider this in the design. I would say that bike has been designed for a desert, very poor.

My husqvarna had these random shut downs, particularly on bumpy descends. I found out it there was some play on battery (and some rattle on descends). Just moved the upper battery mount a couple milimiters down and battery was more tight. Never had the issue again for the last 2 years.

Nice video Dave and may I say, nice to see you have good taste in tools. I have the same Wera torque wrench. Cheers

Good morning Dave,, on all the electrical connections I have use Dielectric grease to help keep water out and eliminate green connections.

My favourite youtube mechanic! I really learned alot from you!

Great video Dave !

great video thanks . i got so fed up with riding my orbea wild in winter in the mud i bought a e gravel bike to ride on the road . last winter all the roads were flooded

Good video, the Toughbook is blast from the past

Love watching your videos buddy. Ebikes are the coolest invention of our time it makes travelling way more fun much more than our cars,

Gotta say mate I have no interest in bikes at all, but absolutely love watching your videos and seeing you get to the bottom of things! Keep up the good work!!

Love your videos, propper job! - will pop into your shop at some point just to say heyup if nowt else

Surely that's not correct? It's like replacing the wiring harness on a car when a connector is the only fault? Or replacing 4 tyres on a car when only 1 has a puncture.

Considering the price of most e-bikes ,manufacturers should be taken to task regarding the selling of them in the uk with such p##s poor water ingress protection. The connectors they use are not even fit for purpose 😡

Always seems a really bad design or decision to put poorly sealed connectors and motors right where most of the water hits a bike, and then be surprised when it plays up . This puts me off throwing a large amount of money at an Ebike for the time being.

i got 4k miles last 2 year on a bosch motor, 3k of those last 8 months, and I live on the Oregon coast. Makes me wonder what people are doing to get water past the seals. The diamondback union 2 has a nice case built for the motor though, I check the bearings last week and they look and feel like new. I think some people are either using pressure washers, or not coving their motor when its on the back of their car in a heavy rain. I don't own a car so that never is a problem for me.

On that model (I have one), it’s easy to keep the moisture out by putting electrical tape along the 4 edges of the battery cover where it touches the frame (on the outside 😅) and continuing a few cm more along the wee gap between the motor and the frame. Now, it’s really quick and easy to do once you’ve done it a couple of times. It looks terrible. It shouldn’t need to be done. But after 3000 km of 4 season riding in Yorkshire’s best slop (Wharny and all the rest), the inside of the frame still looks brand new and I never have any visible moisture (or issues with moisture). The wee holes by the steerer tube for the cables (x3) somehow don’t let water in even in Yorkshire tornadoes 🤔 Anyway, my point? Well, moving beyond the question of ‘why should this be necessary?’, I have zero electrical issues with this awesome do it all e-bike (just back from Revs today 🎉).

Nice video. I have the same bike. It's awesome, I am thinking maybe removing my harness and adding some weather proofing after watching this. The motor could use a good clean out also. Maybe next deep clean day 🤔

Another brilliant video Dave, does that the little tool that you used to take the connections off suitable for all motors especially Bosch and can you provide a link for it please

no doubt an expensive replacement part that should have been more rugged....

Gday mate great video 👍👍 , genuine questions here - is a bicycle mechanic is it s registered trade and you have to do a 4-5 year apprenticeship? Since e-bikes are relatively new largely, what training/schooling have you or majority of bike mechanics done on electric motors / auto electronics? Do the motor manufacturers give all bike mechanics schooling on these motors & tech involved? I myself am a qualified motorcycle mechanic and we used to do all electrical diagnostic in house and only sent components that need re wiring to a specialist motorcycle auto electrician! I personally don’t ride e-bikes but I have a lot of mates that do and from what problems I’ve seen the shops are just replacing components, not repairing or correctly diagnosing ! You’ve probably guest what I’m getting at , is that the massive influx of e-bikes and tech involved are the bike mechanics qualified/ had schooling and are they the best option to repair / diagnose e-bike problems or should my mates just find a quality auto electrician/ tech as surely there’s a massive call for this ?? Cheers 🍻 from Oz

I has this issue with my Trek Rail, after replacing Bosch system and frame twice we concluded it was the connectors getting damaged as the connectors are fixed with no strain relief so getting damaged when frame flexes

First thing I notice is the very poor sealing of the battery/connector assy, bad design in my eyes

In your opinion, would it be a good idea to put a small amount of dialectric grease to each connector to minimize corrosion? I realize putting too much can compromise the weather seal I'm just talking a small coat

My issue is a little different my wife and I were out cycling on our Mustache Samedi electric tandem which is fitted with a Bosch cx motor and two 500watt HR batteries we love to bits ,we have own it 4.5 years covered over 5000 miles for some reason one 1 of our 2 batteries seems to have failed the display shows battery icon no % tried pressing the button on the battery nothing lights up also tried charging without success.

Dave, it's been 30c for a week now here on the Rock of the west of Canazeula. Can't stop for trail touch ups ffs

I have a Samebike lo26 11 750w The screen when sunny day is impossible to see. Is there anything I can do. Or you can do I. E change screen or filter

My shimano e8000 gave E010 error when the battery connector negative terminal was corroded causing poor connection. Intermittent failure. Took quite a while for me to find the cause.

This is exactly the issue that I’ve had for 6 months now. Did the new wiring harness fix the issue or is it too soon to tell?

Mine has an audible knock on every rotation under load. Bosch CX gen 4 never been wet only 740 miles from new.

That seatpost is dying inside

Nice video…. Thank you…. Toodle pip. 👊🏻

Over the last few week I've had lights fail /lcds playing up 😅 ,the usual 🇬🇧 British weather troubles 😅

you would think a bike that expensive would have at least an IPX6 water resistance rating

Was this a warranty repair or did the customer have to pay for the new harness?

I got a bosch 501010 error twice in the last couple of months. I asked bosch what the error was but they have not responded. Anyone know what this error is?

I say to everyone even though it says waterproof put a bag /crisp packet over the lcd screen unit if its bar mounted/kit, I've lost at least 4 over a decade due to heavy downpours. 😅 🇬🇧

Is it not just going to do the same again?

diy kit is better, waterproof controller, and connectors :D i am glad i did a diy e-bike :) and not buy a expensive e--bike from a bike shop :) can make 3 bikes for that price.

How do davy boy, hope ya well

The more I learn about ebikes and their never ending issues the more sure I become that I will never waste my money on one. If I ever get too old or fat to ride my Orange I will just give up and go to the pub instead.

My e bike cracks without warning. Thank god for lifetime warrenty. Not 2 years in and im onto my 4th frame

So, these bikes are crap, with no weather sealing at all. Got it!

Probably trying to tell you something

Rule 1 sell your EMTB before the warranty runs out, they will empty your wallet quicker than a Barcelona pick pocket. True EMTB ownership cost is about £500 to £600 per year depending on mileage, taking into account servicing, depreciation and faults / breakages. Can’t believe the world got sucked in to this fad.
