Oxygen Emate City stopped working

[david1949]

As i live in NI i was worried about buying a e bike the reason because we have no backup here but i went ahead and bought a Oxygen Emate City from 50 Cycles . So was out riding on it today and 12 miles from home it stopped, no power my worst nightmare. So a 12 mile run back home in this heat and in 1st gear and me just had a knee replacement just 5 months ago i was never as glad to see my house my knee is killing me. I checked all out on the bike when i got a rest and it looks like its the motor or the controller is at fault.
I sent a report on to 50 Cycles workshop i am awaiting a reply it's funny the first Oxygen Emate City they sent me did not work properly fron i took it out of the box Oxygen replaced that one now this one has stopped working actually the same thing wrong as the bike they replaced for me. So not at all happy i only use this bike once a month for a 12 to 20 mile run and that only in good weather. When i get this one fixed i will be selling it and spending my money on a good high end bike .
I let you all know how long i wait before i get it fixed it will be interesting to see what Oxygen or 50 Cycles do next. I hope if i have to send it back they supply me a box and pay for the carriage each way .

I am sure they will look after you, let us know how you get on.Could they not send you a controller to try on it first, Do you have a multi meter.?

I take it you have checked the main fuse in the battery is ok.?

 

[david1949]

Before i contacted anybody this is what i have checked.
(1) Took off battery checked all fuses checked pins at bottom of battery checked for voltage at bottom of battery all ok i would have thought all was ok with the battery as i had 3 lights up and the unit on the handlebars .
(2) Disconnected the motor plug at back wheel and reconnected it still on joy.
(3) opened compartment below battery checked all wiring all plugs ok .
(4) all brakes working ok and sitting in the off position
So that as far as i can go there is just on power at the throttle are the pedals this is exactly the same fault as the first bike they sent me had to return it they then sent me replacement for that one.
As for checking the controller i would not have a clue how to do that i only have a small AC-DC meter for checking the 12DC volt battery in the motorhome

If your display is on, but the motor doesn't go, it'll be a problem with the wiring harness, which is not possible to test yourself. Unfortunately your bike will probably need a new harness, display and throttle, but it needs a competent person to properly test it, which i guess means that it'll have to go back to Oxygen or 50 Cycles.

D8veh.....I don't know the Oxygen well but is the bike a speed sensor with the usual magnets in the crank disc? ....these discs are vulnerable to moving out of position or cracking,when they break they don't grip on the crank spindle and therefore fail to rotate....our experience is these discs are the most common reason for failure of power on an ebike.
Worth checking and getting a replacement disc fitted before going to the effort of returning the bike.
It's not always obvious that the disc is not rotating-we had a no power bike that floored us for some time,one of my guys spun the disc and the bike leapt off the bench.
The wire from these discs is also very vulnerable to damage.
Only once have we had a broken wire inside the harness,that is very rare.
KudosDave

Good point, but the throttle's not working either.

Thank you all for your replys i find it strange that this is the same fault as the first bike they sent me all lights on but no power from pedals or throttle. But a new wiring loom could it not be the hud motor or the controller the plug for the hub motor has about 4 or 5 pins on it but i don't know how to test it to see if it is getting power if it has to go back i would like to think Ougen or 50 Cycles will foot the bill as it is still under warranty when you look at my problem we need more dealers around the country . As i said before this is what i was worried about before i bought and now it has come back to hunt me.

The motors are extremely reliable and rarely give problems. The controller's are also pretty good. They''re sealed inside, which prevents most problems. Oxygen went to a lot of trouble to try and prevent problems by using high quality components and connectors, but despite that, problems can still occur, as with any bike. Buying a more expensive bike is in no way a guarantee against that. You'd be surprised how many Bosch bikes had to go back for repairs.

Bike manufacturers lose a lot of money when bikes go back for repair, so they're normally very quick to identify causes of problems and solve them, otherwise they couldn't stay in business, so as long as you chose established suppliers, you have the best chance of minimising the chance of problems.

Hi d8veh i can understand what you say but they are over in mainland UK and i am here in N Ireland
if this prodlem had happened when i was out of warranty the bike would have had to sit in my garage till i was over to see my daughter in cambridge in June next year. So if it not the motor it must be the controller or am i missing something. As for a multimeter i only have a small Analogue one and that can be hard to read i had no idea these bikes were so complicated how do you go about testing the controller please.

 

[Deleted member 4366]

It'll be the harness and display that's faulty. The display has software in it that controls the PAS and throttle. I'd be surprised if Oxygen or 50 Cycles can send a box. They will certainly arrange collection. It might be a good idea to go down to your local bike shop to see if you can get a box from them because they normally have to chuck them.

 

[david1949]

Hi dveh i never thought about display on the handlebars as all the lights were light to tell me i had a full battery and the high med low lights all work so there software in there that controls the pedals and throttle thank,s for the information. I going away for the w/end hope to have a e mail from 50 Cycles or Oxygen when i get back as to what their going to do. might just keep sending me parts to try but i do hope they will arrange for it to go back the display on the handlebars has a No 790 on it

Dear David,

Firstly I'm posting from my short holiday break and i'm really sorry to hear about your bike. You rang me yesterday on my mobile but I could not hear clearly who was ringing due to poor reception and advised you to send us email about your problem so somoene could deal with it.

Now you are saying that you are hoping for an email from us or 50 Cycles but I've logged on the business mail and can't see any message from you so it will be very hard for us to respond to you if you have not even send us anything. Instead I can see a whole new thread on forum about problem which is quite frustrating because you are posting first here and I feel it would be very reasonable if you got it in touch with our support first.

We really want to help you but doing things this way does not help neither us or yourself. Based on the info I've read here on pedelecs I assume you have a bike with 790 display which has a direct cables to the connector and no harness (loom). From the easy things I would suggest to try to disconnect the brake cut off switches down the controller and then see if it makes any difference. If I remember well this will be a black/yellow core connector. There are two of them and in case one of the switches would be on at all times it will disable the whole system.

If you got in touch with 50 Cycles (which I hope you did at least with them) then please wait for their contact.

all the best

Andrew

I don't think he said which display he has. I assumed the LCD display because it's still under warranty.
just to be sure, can you tell us which display you have, David?

 

[david1949]

Hi d8veh the display i have is 790 that all that is on it it has the lights at the top of display for the battery and the Low MED and high light up i hope this helps.
