Until the battery can or can't be ruled out Sami is stuck, it is pointless willy nilly changing components as it then gets costly. If I fault diagnose it is the first item I check to confirm it's operation, after that I fault diagnose for any sudden voltage drop. After these I look for...

The power button on the handle/bar display only stops the led/lcd from powering up, it doesn't prevent power direct between the battery and controller.

Further more to Sami's battery problem at 40.4v max charge I would say possibly one cell group at least may only be charging to about 38v - 39v or so and this one is the one causing the battery BMS to cut out as the one cell group hits lvc so much sooner then the others. Only opening the...

If the battery is only charging as we have found now to only a little above 40v then the battery is certainly toast I believe and is currently in a worse state then I mentioned my pair of ageing ones are in #42. At least with my pair I can coax them with good current control into providing up to...

You will as Kirstin has said blow the inlet Cap instantly, the 36v controller has only 50v rated Caps and not 63v of the 48v ones.

Now , you know how a proper mtb looks after a proper off road ride. As Eddie in the past has shown many pics of his KTM's, but looks like now his latest bike motor has come a cropper after his last ride. I think Eddie needs to fit a motor snorkel now.

All you need is simple push button on off switch which can handle the voltage, no amps flow when wired on the V+ side. All current flows through the untouched V- wire. I do just this and use a simple pane mount latching push switch. With my battery holder I had the room on the base part to...

40.4v isn't good fully charged so that changes things now, shame this wasn't mentioned in the first place. Though your issue is still battery related we should be able to aide you and assess how bad the problem might be. It suggests the battery is unbalanced and that at least one cell group is...

As I said fair weather rider, that hardly adds up to more then a run along an old railway/cycle path after it has rained a few days before.

SW is a fair weather rider his bike doesn't see dirt or mud.

Are they the Tanus tyres ? If so I think the ride will be quite harsh and you will feel every lump and bump on the road.

I'm going to throw this one in to see if we get an answer or simply played with. Charge the battery fully and tell us the voltage it sits at.....

It's not but in the main wider tyres to cope with offroad terrain better. You can ride on roads but a more road orientated tyre will more efficient, safer and a lot quieter. Knobbly tyres are better for grip on loose, wet muddy terrain and ride over the surface better. On the road the...

If a bike stops working that was ok before then look at the following first: 1. Check battery voltage and does the led/lcd come on and stay on ? If yes then go to #2,3 & 4. If no then look at battery fuse and power connections. 2. Disconnect throttle. 3. Brake sensors/cut outs if fitted...

A clarification Flecc if you don't mind as you are the knowledgable one in pedelec law and might help users out. The throttle option active only after you pedal this is allowed as it is deemed not a twist and go form a standing start.

Q128c is 500w . The SWX02 at 48v with a 17a controller will be able to output 816w before inefficiency losses and about 650w at the wheel if required. 650w temporary should be more then ample for most people. Any motor power comes via controller rating (Amps) and a suitable battery to deliver...

The difference is Woosh are a company who will have insurance and an agreement set up and unfortunately Deus you are like the rest of us a nobody/a private citizen who they will refuse to deal with when lithium is mentioned.

The issues arise when an accident occurs or some one is injured esp a third party, up until then it is all hunky dory. Your bike is then gone over with a fine toothcomb and experts will decide if it is over powered or speed adapted.

Which cells to use depends on the max controller rating, do you know what the controller rating is ? You need to select cells that will have more amp head room then the max that the controller can take out of them. The reason I mentioned the hg2 is that you battery is 7s 2p so two cells in...

The Suntour system is a closed electronic one like The Chinese Bosch ones and parts only available through dealers, in this case Halfrauds. If you can't get it working at all then you need to spend about £120 and buy a completely different leccy kit for it. You can keep the hub and battery but...
