We will know for sure what it is , if it has a code on it.

Saracen you don't seem to understand pedelecs won't be banned , the law is set out so it just has to policed as other motor vehicles are. Cars ,vans etc are banned because some of them speed , it is the end user and the vehicle that is punsihed or gets confiscated. In the case of an illegal...

The 5v regulator is clear to see , top right of board next to the beige resistor.

All levels should reduce accordingly. All PAS %'s are based on the set maximum. PAS1 13%. PAS2 20%. PAS3 33%. PAS4 50%. PAS5 100%. One can see this with a LCD3, the watts output in each PAS level reduces when one experiments with the C5 reduction.

Giant usually use CANbus so any battery will have to be a Gaint supplied one, not a generic two wire one such as a Yose battery. There is one reason why one managed to buy the bike for cheap and that is the locked in Giant servicablilty which is expensive.

Typically with nearly most china wiring one can be certain that Black is gnd if not present then Yellow . Red is 5v or if not present Brown. After that signal is the obvious third colour. Blue is used for volatge but that is usually additional voltage wiirng on displays. It is only with...

Asking first is better then guessing . Straight away we would have told you PAS = yellow /gnd, Red /5v & blue signal. Connecting to the controller would have been been simple once one confirmed the controller PAS output voltage was ok.

Simply change C5 setting, some displays use a % reduction of up to 50% and some by 5a max in - 0.5v steps. The 9 mosfet has greater heat sink abilitly and may have better mosfets, tbh I haven't cehcked the fets to see.

If the PAS works in reverse then either setting is wrong or one can try changing the PAS sensor orientation to see if that works. Rotate the PAS unit on the axle by 180 degrees , one will have to remove the crank arm to pull the PAS off and rotate the direction ( the wire out let direction...

Issues are always down to the user not knowing what they are doing, we see it often . Wires are willy nilly connected without having a clue or checking/testing wiring sequences first. It is only when something gets smoked that the logic kicks in to aske for help but by then the damage is...

One doesn't need to take the battery a part , but just find the connection point and look at the connector on both parts for any signs of discolouring. Like wise do the same for the controller to motor phase wire connection. Their is another point where power delievery can be an issue and...

The original yose kit was quite good , they used a clone Bafang swxk type hub and a nice KT set up with LCD3, then they took a step backward and went with Lishui speed controller. They sort of upped their game a bit with the introduction of the AKM95 hub, the kit would be almost perfect if they...

Banning won't happen , the law states what is legal and it is a policing matter as it is with other motor vehicles. I saw a guy on a disbaled buggy yesterday and he was zipping along at a good 15mph on the road , somehow it won't lead to them being banned .

Their have been reliabilty issues with the kit and others have reported issues before. Check the battery to controller connection , disconnect the connection and check for burning or pitting . Like wise do the same for the phase wire connections , if one finds burning or discoloured...

Mosfets usually get hot and thermally cut out if one uses high current draw and rides slowly, an example is climbing steep hills where one draws max power but struggles to ride very fast with a slow cadence.

The mosfets in the controller will depend on the wiring one can carry out mosfet testing with a metre. The controller isn't in the battery but are either in the modual/receiver that holds the battery or is contained in the handle bar bag. However mosfets work or don't, the half way point of...

My Q128C had a stick on paper label , it now has a stick on aluminium etched label. The hub is the same size as most 250w hubs and in most cases smaller then some Bafang 250w hubs. There is no test to prove the motor wattage only the etching/label on it. Now that labour are in power one...

What I meant is how man drivers give way/stop for pedestrians at crossings esp drop kerb ones, they don't. One often has to walk out to force them to stop, very few seem to realise the new vulnerable road user law.

AKM is short for Akiema motor company. KT is Kuenteng electronics. Both very highly regarded. Other OEM supplied bikes have used the AKM128 marked as 250w.

One can simply tell if it is thermal cut outs, when it occurs see if one can touch /hold the controller base at the bottom of the battery without scolding ones hand.
