Giant are known for high prices with their proprietary bikes , it's a case of buyer beware . But it isn't just Giant , all of the proprietary bikes are all locked in systems with handshaking so they can charge silly prices. The above is the case for non warrantied bikes which is most of them...

With the std 9 pin hub motor connector there is no wiring to be done it is plug and play. Buy a suitable KT PAS(highly recommended) to fit the BB and it is plug and play. Brake cut off levers aren't needed with a KT (unless one uses a thumb speed switch). If brakes have existing cut offs then...

9 pin motor cable is a std connector, most Speed controller or Current controller should be compatible. If one want's the best available controller type at a good price then a KT controller is by far the pick of the bunch under £100 , £100 also gets one a compatible KT LCD display from the...

That connector is for the trunk wire connection from controller to display, it is much too small wire wise for motor phase and hall .

Show us the hub motor connector. Typically to turn it into a generic system one has to replace the controller and handle bar display , £80 - £100 for a nice pairing. If the bike uses a TS BB then that would likely need to be changed. The battery BMS if using comms would have to be replaced...

Those DJ connectors are pennies so one can't buy just one , buy a whole box/kit or simply cut the end off and solder wires together to extend the length. Motorcycle Car Electrical Auto Connectors Terminal 2.8mm 2/3/4/6 Pin Replacement | eBay

Any one in their right mind would never buy Lion for solar installs, LFP or as we like to call them lifepo4 are much safer for static use.

The state of how the box arrives is not the fault Ali Exp or the seller, ultimately it is the courier and could easily be down to one of the UK couriers who all suffer from poor handling/care of parcels.

For a product to truly be a bargain it is needed to be seen as selling at the 'RRP' , otherwise it is just sales gimmick/con to sucker in the gullible.

53.35v suggests a weak/dead or low cell as does the green charge light. Green charge light in this case indicating no current is being asked for by the BMS, so BMS has sensed a fault.

Reminds me of the lod addage with business. To make a small fortune , one has to begin with a large fortune first.

How fast is the bike moving at cut out.

Giant use there own software so any other Bosh peripherals will be incompatible, which means also chargers. It is a cash cow to prevent owners using non Giant dealers .

One needs to find out the max speed that assists one in L1 & L2 and therefore also L3 , then ride the ascents without hitting the max speed in each level. As one reaches near the max speed assist in each level the power/current will bqck off so one will need to try and ride 1 or 2 mph under...

Derestrict the speed limit and tell us the max road speed in L3, this will give us an idea to your hub winding RPM. For hill climbing one needs torque and a low wound rpm hub.

Controllers stating wattage is pure nonsense as it has no meaning , the importance is max current it can deliver.

Being too lively is the complaint from a few users of these speed controllers ( typically they are just poor), the user has no control at all with the power delivery and one reason why some of us always advocate buying KT brand that utilises far better current contriol. Your controller may...

The only heat displayed with some LCDS's is ambient air temp , motors very rarely have a heat sensor in them unless one retrofits one. My TSDZ2 will show motor temp but only because I added a sensor and used the OS firmware.

As we have alluded to, one will need a specific CANbus charger as it has more then two pins for comms, a generic £10 - £15 jobbie won't cut the mustard so expect to pay over £100.

Chargers can and do get very warm /hot, my Sans chargers got very warm and non use fans so I modded the casings with several 12mm vent holes and most importantly one directly above the voltage regulator to allow me to adjust any voltage annomoly. A few vent holes and the chargers now run much...
