Reverse/ swap the magnet disc face , the magnet field is wrong as they are north or south.

We need to see the P 4 setting & C 1, C4 & C11 settings as the throttle may be deactivated, also C1 setting to see if PAS value is correct.

All my rear hubs have been 135mm inc the yose cst hub.

A voltage test won't tell you how much life is left in the battery as even a knackered battery may charge to full still , it will though tell you the battery voltage . It will need cycle testing using a known rate of draw down current and a watt meter to discharge it and then charge it up...

The connector name is known as IEC T type . Option G form this listing. 29.4V 42V 54.6V 2A Power Charger for 24V 36V 48V Li-Ion Battery Electric Bicycle | eBay Always check pin polarity is correct before connecting. With any charger follow the simple rules , monitor when charging, don't leave...

Most BMS are simply passive balancers and only balance at the top end voltage , as you know via the bleed resistiors. But a wider difference in voltage may not balance out in one go An active balancer works a bit different and will balance at any time during the voltage range if a wider...

I think a lot of issues with knackered cross head screws is not using the right screw bit type and size , also best to use a brand new one with no wear.

Thanks for doing this WR , I know you were doing this early on but wasn't sure you were continuing. Over all that is pretty damn good for no name china cells. Balance can vary a little and depends on the specs of the BMS in use.

It's the bed length and width that make it tricky.

My new 65kg payload trailer should be here soon, I need a slightly smaller one then my super dooper modified CF one fo my local use where I have to go down a small narrow alley way with a tight 90 deg corner to get to the bees. The modded CF is too large for the bend.

I will let you know in two or three years if fatique /vibration brakes it but doubt it as there is no moement to allow it to stress the metal. I have the same set up on my Boardman which does my off road stuff , 6 years and no metal fatique.

Unless blind the giveaway is the name/branding on the frame , of which both appear. An older out of production bike but a good one all the same, easy to repair and retrofit electrics should ever on needs to.

One has to be careful if the rotor screws are removed as water /moisture will enter the motor in the wet and will rust everything solid, if not using rotors then refit the screws ensuring they are water tight , employed some ptfe tape or thread lock to the threads. Often the LHS of the motor...

You can use any temporary connection for testing as long as they are insulated against shorting with each other.

If the motor is sensored then one needs to test the Hall sensors for operation as a failed one will prevent operation but first one needs to ensure there isn't a phase short within the motor or the motor cable. With the new controller disconnected does the wheel turn by hand easily or can one...

The phase wires are soldered in to a mt60 so they can't simply be swapped , they will need de soldering or cutting and another connector source to see if they work.

If you are going to test all 36 combos , get your self a string of those 30a amps screw connector blocks (the clear /opaque plastic ones used by sparks. Simply just change the wires on one side to do all the testing, then once (hopefully) you get a good working combo then solder up all your...

One can ditch the LCD3 stand up bracket for a simple aluminium one , then one can have it sit tight to the handlebar stem so it lays quite flat. I use a bit of 1mm ali as a bracket and drilled a suitable hole in it so that the stem screw/cap clamps the bracket then align the screw holes in the...

Typically yes , those sytems with 5 PAS levels or more use a % of current /power available with the top assist being maximum power and a kin to throttle full power. As an example the KT current control system's I use have PAS1 13%, PAS2 20%, PAS3 33%, PAS4 50% & PAS5 100%. How a brand like...

Problem is the battery led may indicate they are charged but it doesn't tell you the SOC, it sounds like a low cell group or one that sags heavily very quickly and can't hold up the voltage for long. A d8veh/saneagle has said in the end the cheapest option if mum likes the bike is to bin the...
