    CYC PHOTON

    How is the drag when pedalling with the motor off? Is there any at all, or does it totally disconnect from the internal gearing?

    The Cycle Satiator, universal charger for the enthusiasts

    The solution is a replacement faceplate sticker and a differently designed clear plastic piece that goes between it and the OLED screen. If the plastic piece was a only a stand-off frame around the screen then this probably wouldn't happen. Alternatively remove the plastic piece altogether and...

    New "TSDZ2 Torque Sensor Central Motor"

    I wrote this up for someone a while back but never did anything more with it. After all this, I really just wanted to get on with riding my bike again. If you search through my post history you will find many photos documenting my rebuild, and if anyone would like to compile it all into a wiki...

    The Cycle Satiator, universal charger for the enthusiasts

    Indeed, and I would have thought the membrane vent should prevent it but since it's happening between the plastic it probably can't escape.

    The Cycle Satiator, universal charger for the enthusiasts

    Has there been any announcement of a fix or recall for the screen problem yet? Grin's video about replacing the display shows there is a second piece of plastic underneath the sticker faceplate. https://www.youtube.com/watch?v=VzpCg_TYk00&t=57s It appears air bubbles are trapped between them...

    New "TSDZ2 Torque Sensor Central Motor"

    Has anyone experienced a high-pitched buzzing coming from the VLCD5 when under power? It stops when I stop pedalling.

    Tsdz2 firmware open source adapted to vlcd5, vlcd6 and xh18

    I somebody could please explain the issue into a single post and what we ideally need set for OSF that would be helpful. I am currently not altering the option byte when flashing with OSF, as per Buba's original release. So far all I can figure out is that Option Byte 2 can somehow get changed...

    What exactly are the different values 20 & 28 supposed to represent? I find a lot of talk about the option byte but no good explanation. :(

    I recently received mine and it has the same problem. Has anyone had this remedied under warranty?

    Tsdz2 firmware open source adapted to vlcd5, vlcd6 and xh18

    That's what I found too, it works better at higher speeds and the problem is worse when accelerating up to cruise speed, if already travelling around the cruise speed it's not so bad. One other thing, in my own port I had a rare problem of the displayed speed freezing and the motor continuing...

    Tsdz2 firmware open source adapted to vlcd5, vlcd6 and xh18

    No worries, I was just curious. Is cruise mode all working properly? In my own port I had some issues with it overshooting the target speed a lot, then cutting all power until the speed came back down. I'm not sure if it's supposed to be more intelligent or that's normal operation. I did notice...

    Tsdz2 firmware open source adapted to vlcd5, vlcd6 and xh18

    Thanks. I wasn't sure if this was as intended as it still allows a single attempt at subsequent writes. Also were your reasons for manually saving the config and not automatically after a setting change? Was it mainly out of concern for wear on the EEPROM?

    Tsdz2 firmware open source adapted to vlcd5, vlcd6 and xh18

    At some stage Mbrusa has added a limit on the number of EEPROM write attempts in eeprom.c. The original code continually tried rewriting but now it only tries 3 times then throws an error. However, it seems that ui8_error_number does not get reset to zero, so all further failed attempts at...

    No dramas, it was just a thought and with everyone's help here I've learned enough to scratch that idea. :thumb:

    The Cycle Satiator, universal charger for the enthusiasts

    Thanks for the info. If the batteries were at very different SOCs, say one depleted and the other half full, would it be OK as long as the individual batteries can handle the charger's full output once they were behind? So, if I was charging at 8A in parallel I'd need to ensure that each battery...

    The Cycle Satiator, universal charger for the enthusiasts

    Is it possible to charge two batteries simultaneously with a Cycle Satiator? I have two identical EM3ev 52V Jumbo Sharks that I'd like to charge at the same time. Presuming they are off the bike, do I need anything fancier than a splitter for the battery charging ports? How does the Satiator...

    What should low voltage cutoff be on a 52v battery

    I have an EM3ev 52V Jumbo Shark with Samsung 35E cells and am using it with a TSDZ2. The cells discharge cut-off is rated at 2.65V and EM3ev tell me the BMS LVC is set at 2.75V. From what I can gather here, setting my controller's LVC to 0.5V over the cells rated 2.65V should be considered...

    My attempt at a lightweight EMTB with torque based PAS

    How's the torque compare to the TSDZ2, strong enough to get up steep inclines without overheating? And how do you find the torque sensing in comparison? Any delays or motor overrun issues? Did you just use a standard bicycle chain for the drive chain? Any other problems now that you are not...

    New "TSDZ2 Torque Sensor Central Motor"

    I received a couple of spare parts recently and there were some interesting changes. First, the blue gear 609RS end ball bearing was very firmly fixed in place whereas it would spin within the gear on the one that came with my motor. And now the drive side cover has a small amount of machining...

    My attempt at a lightweight EMTB with torque based PAS

    How's this going, did you get the hall sensors sorted out yet? After looking over the thread again I realised that you lock the axles in the brackets and the the hub motor spins as it normally would in a wheel, is that correct? Did you give any consideration to fixing the motor in position and...

    New "TSDZ2 Torque Sensor Central Motor"

    It was pretty easy to pick off the potting and desolder. I then cleaned up the pads with some braid and isopropyl alcohol. Then unscrew the sensor plate and pull the whole plate out with the wires. The hardest part is getting that retaining clip off and back on again. Some flux when...

    New "TSDZ2 Torque Sensor Central Motor"

    Can anyone please tell me where the 3 springs behind the torque sensor should sit? In the long slots by themselves, or around the nipple in the circular holes? There's conflicting info around.. OK Feet's disassembly video shows them in the circular holes, but other repair guides show them in the...

    My attempt at a lightweight EMTB with torque based PAS

    It sounds a bit like a walk mode that is always running, is that the general idea? Do you feel any motor pull or overrun when you stop pedalling, or will it eventually coast to a stop? Is there just the single stall time setting that times out after you stop pedalling, or does it require the...
