    GIANT Traumas. Are they BATTERY firmware related?

    Evening Mike, Help me to understand your train of thought here. What kind of “incompatibility“ are you thinking there might be on the bike that allows it to run just fine for literally hundreds of miles in between faults?

    GIANT Traumas. Are they BATTERY firmware related?

    The shutdown is indeed the same as an LOS mode in a car without the LO part. Lol. I wonder if the later motor is more susceptible to moisture issues than the earlier one. For sure it has more electronics in it. Shame it’s not easy to swop motors trailside to asses where the fault lies that the...

    slowly but surely the answer is going to appear in my other topic about battery firmware if your interested pal. :)

    GIANT Traumas. Are they BATTERY firmware related?

    All off road too, we don’t do tarmac! The fun we have on these bikes is the ONLY reason I preservere and still want to find a solution. Some of these rides back with a dead bike are pretty grim… lol

    GIANT Traumas. Are they BATTERY firmware related?

    I’m confident now that firmware will help. But that battery is the one supplied with the bike so if it’s now incompatible with the motor or RCOne firmwares, then GIANT have made it so with their OTA updates. However, let’s also not forget that this bike and battery can do 20 trouble free rides...

    GIANT Traumas. Are they BATTERY firmware related?

    So, interesting update. I have been liasing with my local GIANT Shop in Blackpool who has been supremely helpful, especially considering I didn’t actually buy the bike from him. He has been in contact with GIANT who confirm there are firmware changes in the battery management systems...

    Awesome Project. I for one would really enjoy reading about the challenges as you overcome them.

    GIANT Traumas. Are they BATTERY firmware related?

    As a belt and braces excersize tonight I have tried all of the available RideOne Control units from FLED28-07 to FLED28-15 as I have one of each as test units. I updated a couple of them whilst I was at it. Just in case. No change… this 500w battery still won’t power my bike but my mates does.

    Giant Trance E+ Sudden Off!!

    My replacement is also the quietest of the 5 I have had, so definitely a theme here. Somethings been improved.

    New Owner: Giant Trance X E+ 3 Pro 29 - Curious about auto algorithm

    Might be worth taking it to the shop and having them calibrate the inclinometer as if that’s off your assistance will be off too. I think it will always be a bit hit and miss as every rider will sit differently and affect the inclinometer.

    GIANT Traumas. Are they BATTERY firmware related?

    I think we have tried every scenario possible with the swops, but can’t be sure without actually documenting it. You could be onto something if the controller is logging the fault, but then if there actually was a battery fault at all, it wouldn’t work on his bike either. (We would assume) This...

    GIANT Traumas. Are they BATTERY firmware related?

    I understand your thinking and appreciate your input. Brainstorming is valuable. I have been over and over this with every scenario imaginable. Two facts rule out connection problems if all things were equal. 1) A faulty battery would not work on any bike. 2) A faulty controller or loom would...

    GIANT Traumas. Are they BATTERY firmware related?

    Same problem today. Bike did the first ride at Gisburn just fine on my 625w battery. About 12 miles and 2500ft of ascent. Had lunch, went back to car, we all swopped batteries and started another session. About an hour in, mine dies and won’t stay on. I have to borrow Steve’s battery to...

    GIANT Trance "Bench Test" Rig

    According to my notes, it’s Main battery connector £35 147L-HDB000-40 Be aware that different bikes have different connectors. This would NOT fit an MY19.

    GIANT Traumas. Are they BATTERY firmware related?

    Hi, oh yes, indeed they have had it back. I have likely detailed it elsewhere but here is my tale of woe… (I’d grab a coffee) MY20 Giant Trance E+2 Pro Collected brand new: Feb 7th 2020. This bike was a trade up for my rejected MY19 E+3Pro Which had a hub, a motor, a fork, 3 controllers and...

    GIANT Trance "Bench Test" Rig

    That was an “example” of how I suspect the control process works. I’ve no idea how many amps it might be mate.

    GIANT Trance "Bench Test" Rig

    I have absolutely no idea to be honest. In theory, if they are regulated like a cars electric motor then it requires a canbus torque request which will be calculated back as a currrent requirement for the motor which is likely where the ceiling sits in the software as we have regulated...

    GIANT Trance "Bench Test" Rig

    Damn. So what the hell is killing my bike randomly as im almost certain that all we had left was moisture in the motor, perhaps entering via the vent disc. Mind you, that was until the latest train of though pushing me towards battery firmware. (See here)
