    Grin Satiator: Any way to force battery recognition'?

    I stupidly left my ebike on all night and, this morning, found the battery totally flat. Hooked up the Satiator but, even after being connected for 3 hours, it is not recognizing the battery as being connected. Is there any way to force the charger to start charging?

    CYC PHOTON

    What was the sprague clutch's failure mode? Gradual or sudden? If sudden, did it strand you by making the bike un-pedalable? Did the sprague clutch failures occur at about the same miles? I am thinking in terms of pre-emptive replacements. When cleaning & lubricating, did you just put grease...

    TSDZ2 Large Sprag Clutch: What Causes Wear?

    Not the clutch in the blue gear, but the larger one. Is it worn more, the more hours that the motor is assisting? Vice-versa? Is the failure mode sudden/total or gradual? Mainly, can failure strand the rider by rendering the bike not pedal-able even without motor assist? Finally, can...

    TSDZ2: How to Set Odometer?

    Big thread indeed! I found a post by the developer that said v0.20.1c-4 contains a fix for the problem. Thanks! Now all I have to do is: Find out where to DTL that version from Figure out how to make my little PC/Motor hardware interface thingie flash the motor's mobo. TSDZ2 Motor...

    CYC PHOTON

    28 gets me a stump-pulling low gear. That said, I get spun out in top gear at 18-19 mph. But the motor is on a tadpole trike and not a bike and the trike has it's limitations - which make a really-low Low and not much of a High reasonable for a semi-cripple like me: It's seriously heavy with...

    CYC PHOTON

    FWIW, I am running a 28-tooth ring on my Tongsgeng. The answer is a 104 BCD adapter available for cheap on Amazon: https://www.amazon.com/gp/aw/d/B07Z4HY3Q4?psc=1&ref=ppx_pop_mob_b_asin_title

    CYC PHOTON

    As a tall TSDZ user, another Photon feature that catches my eye is the ISIS crank compatibility. I would like very much to try my 180's (left over from my MTB days) on a mid-drive.

    CYC PHOTON

    Two questions: What prompted the replacement? TSDZs just worn out? Did you ever replace the TSDZ's blue drive gears or sprague clutches? If so, how often?

    CYC PHOTON

    Can anybody who actually has a Photon confirm or deny that it accepts the de-facto standard 104BCD chain rings? Either way, your Photon model? I would note that, although my TSDZ2 did not accept 104BCD rings out of the box, I was able to buy an adapter for cheap on Amazon that gives me access...

    TSDZ2: Calibration for Real-World Human Power?

    I am trying to set up my TSDZ2 w/aftermarket firmware so that the "Human Power" readout bears some relation to reality. Not having access to any of the bike power meters, I am fiddling around with Settings.Torque Sensor.Weight on Pedal and one of the Settings.Assist Levels.Power Assist values...

    TSDZ2: How to Set Odometer?

    Open-Source Firmware Version 20.1c-22 When I go to Settings/Various/Odometer and change the number, it jumps to 1,400-and-some miles when I exit "Change" mode. IIRC, I succeeded in changing the odometer value once in the past, but do not recall doing anything different. What might I be missing?

    TSDZ2 OSF: Unable to Change Odometer

    At first I thought it was my 860c being on the way out. Then it failed completely and I flashed/installed a new one. But, even with the new 860c, I am unable to change the Odometer value. It increments & decrements while in Edit mode, but reverts to the original value when I exit Edit mode...

    TSDZ2: Is my use Light, Medium, or Heavy? Maintainence Schedule?

    TSDZ2 mounted on a ICE Adventure HD tadpole trike running through a Rohloff 14-speed hub. Trike + rider = 308#. No throttle connected, PedElec only. Used mainly to help on hills and against headwinds once I start to feel like I am "Grinding". Typical range w/that use on a "52V 14AH... 40...

    TSDZ2 Sprag clutch

    With a failed clutch, can the bike still be pedaled - albeit without electric assist?

    TSDZ2 blue nylon gear: failure mode?

    Sounds like a candidate for pre-emptive replacement whenever the nylon gear is replaced.

    TSDZ2 blue nylon gear: failure mode?

    Not charging to over 80% or discharging below 20%, I get between 30 and 45 miles on a charge from my 52v 700wh battery from https://www.electrifybike.com/collections/batteries/products/52v-40-amp-14ah-super-shark-e-bike-battery. Basically, the battery has considerably more miles in it than I do...

    TSDZ2 blue nylon gear: failure mode?

    It is possible that I'm finally going deaf, but most of my life I have been kind of neurotic about noise and I can barely hear my nylon-geared TSDZ2 except when I am pushing 400 watts through it - then I can hear some noise, but it is comparable to the noise my Rohloff hub makes in 7th...

    Can you ballpark the number of miles on that bike?

    How many watts is full power? 500?

    TSDZ2 blue nylon gear: failure mode?

    Does the blue nylon gear on Tongsheng's TSDZ2 tend to fail catestrophically/totally or gradually? i.e. does it give off warning noises vibrations that tell one that it needs replacing, or does it tend to just totally strip the teeth?

    TSDZ2: Pre-emptive blue nylon gear replacement?

    Can anybody cite a number of miles for pre-emptive replacement of the blue nylon gear on Tongsheng's TSDZ2? One guy said he does it at 800 miles, but his use case seemed extreme compared to mine. I have mine mounted on a tadpole trike, capped at 400w, and used as seldom as I can - mainly when...

    My econo-e-bike

    If that ThudBuster is the origional single-bolt version, I strongly advise replacing it with a two-bolt version. Reason: They break. The head of the bolt shears off. Mine broke and I escaped with minor injury after being suddenly introduced to the bike's top tube. A guy in California...

    How to maximize battery shelf life?

    INR (lithium nickel manganese) chemistry. I have two batteries and it turns out that each one has more miles in it than I do, so I want to store one against the day that the other wears out. Assuming a life of 500 full charge/discharge cycles and keeping the active battery between 20 and 80...
