    Thanks for the reply! Yes, I suppose I will just have to crack it open if I want to find out for sure. It seems nearly impossible to tell from those disassembled photos. -Jon

    Bofeili Crankshaft Drive

    Many apologies for the necro-bump on this thread, but I am wondering if there is a way to tell (maybe from the disassembled photos) whether the motor is wired in a delta vs. a wye configuration? In my belt-drive / IGH conversion, I may have over-geared the bike... 72T beltring up front, 30T in...

    Rohloff splined sprocket internal diameter?

    Chalo, I’d say I wanted all-weather, low maintenance durability and no more chain grease on my pants. So far… mission accomplished :) Also, to some of your previous points, I guess I got lucky in the sense that my bike’s frame and wheel setup was conducive to the conversion… I get that not all...

    Converting to a VEER Carbon Belt Drive (split the BELT, not the FRAME) and IGH

    All- In case it's useful for others, here's a post on my experience converting my mid-drive e-bike to a carbon belt drive and IGH setup. The frame is all carbon fiber, so it can't be split to pass a Gates carbon belt through in the normal method. The thread below is not very obviously named...

    Rohloff splined sprocket internal diameter?

    Thank you! Even a blind squirrel finds a nut once in a while ;) Short answer to your question: It’s a bitch. Longer version: First, remove axle nuts (which I actually cut external threads onto so I could still use my Rackstand, so… added challenge) Next, drop wheel just a bit so I can...

    My M2S All Go Carbon (Alienozo) w/ Bofeili Crank Drive

    Ok, so I’ve shifted around my modification “phases” a bit due to some unplanned repairs. The chain got caught between the front chainring and the motor housing, and when I pedaled backwards to try to free it (not realizing what had happened), it partially unwound the housing and allowed some of...

    Rohloff splined sprocket internal diameter?

    Also, one footnote… that Veer rear sprocket was harder than woodpecker lips! I tried drilling through it around the circumference of the circle I wanted to cut out and it absolutely scoffed at me. Like… I could barely get the surface finish off and my perfectly new carbide-tipped milling bit...

    Rohloff splined sprocket internal diameter?

    FYI… took me a year to get around to doing it, but it worked :) I ended up being more “lucky” than “good” with regards to the major obstacles one should expect to face in a belt drive and IGH conversion. First, front beltline. In the front on the crankset, I wanted the LARGEST possible...

    What retailers / OEMs use the Lishui LD-LS83 controller?

    More good points, thanks for the insight! This carbon frame is REALLY beefy, but I will take care with its insides nonetheless, as you caution. I very much appreciate a nice, clean-looking, “bike-like” frame without a lot of component bags or bolt-ons that scream “Frankencycle!!!”, so I’ll...

    What retailers / OEMs use the Lishui LD-LS83 controller?

    It takes quite a bit of poking, prodding, and twisting to get the current harness to snug up into the same cavity that the controller goes into… definitely not a lot of space left over for things to rattle around once it’s all in there! As for heat dissipation, I have thought of that as well...

    What retailers / OEMs use the Lishui LD-LS83 controller?

    Thanks for that reply! I do like the Lishui controller but if the KT17A is capable of true FOC control (or is at least sinusoidal) then maybe that would do the trick. It’s the right size, is capable of 48V, and my display is a Kunteng LCD9, so it ought to be compatible out of the box :)...

    What retailers / OEMs use the Lishui LD-LS83 controller?

    Thanks! That looks like a great controller, but it’s still about an inch too long and a bit too tall to tuck into the space I have to work with (inside a carbon frame downtube, above the battery almost where it meets the top tube… and mashed in there with all the wiring, too). The height I...

    What retailers / OEMs use the Lishui LD-LS83 controller?

    Anyone have any ideas on this? Definitely looking for this specific controller for two reasons: 1) Small enough to fit in existing 36v controller’s location 2) I’ve already climbed the learning curve re: re-flashing Lishui controllers with open source firmware and I like the flexibility that...

    Is there a list of controllers compatible with UART protocol displays?

    SOLVED. https://endless-sphere.com/forums/viewtopic.php?f=30&t=106862&p=1661131#top I was able to flash my Lishui controller (after climbing a bit of a "learning curve") with Open Source firmware that enabled me to not only dispense with the pesky speed limit but also select the display...

    Lishui "Open Source Firmware" project / KingMeter 5S

    SUCCESS! Or, at least... more success than I'd had thus far. I will talk through my experience to help fill in the blanks from the wikis below for other novices who may not be as familiar/comfortable with programming. By comparing the wiki at: https://github.com/EBiCS/EBiCS_Firmware/wiki...

    Thank you once again for the assistance! Yes, I’ve seen that wiki and it has been a big help so far. I’m sure this is all second nature once you’ve done it a few times, but it’s all a little daunting for a novice. I’ll have another go this weekend and will report back. Thank you!!! -Jon

    Lishui "Open Source Firmware" project / KingMeter 5S

    Hello again, and I'm sorry to have to keep asking for help! Trying to find the documentation and FAQs on my own, but I'm hitting some "rookie" dead ends. If there's somewhere else I should be looking rather than posting questions here, please send me on my way and I'll try not to bother again...

    What retailers / OEMs use the Lishui LD-LS83 controller?

    See this one here: https://www.lsdzs.com/ls_product/showproduct.php?lang=en&id=137 It's 48V nominal, 25A peak, sinewave, has the connectors I need, and is compact enough to fit in a very space-constrained application I have. The only problem? I can't find where to buy it! Any ideas...

    Lishui "Open Source Firmware" project / KingMeter 5S

    Ok thank you so much! That is great news. I will try messing with the Java GUI first to see if that gets the job done, then will consider erasing/reflashing if not. -Jon

    Lishui "Open Source Firmware" project / KingMeter 5S

    Hello, and thank you for all your hard work on this project! I have a Lishui controller for my Bofeili mid-drive bike... it's an LSW 913-33-5F and the board on it is labeled LSW90B-V02-130509. It seems to meet the requirements laid out in the wiki to be re-flashable. I would like to be...

    Is there a list of controllers compatible with UART protocol displays?

    Ok, so I had a look at the stuff on the Lishui OpenSource reprogramming... looks like there is potential to not only improve performance with some sort of FOC-like control, but also to change the display output protocol. That'll be my "plan A" as it involves utilizing the parts I already have...

    Is there a list of controllers compatible with UART protocol displays?

    Thank you for the reply! That is a very useful clarification. The DPC-18 supposedly works with many Bafang motors… BBS02, BBSHD, Ultra, etc. so, if those use the KM5S protocol as the Lishui does, then perhaps it is the handshake that is the issue. Are you saying that Lishui controllers use...

    Is there a list of controllers compatible with UART protocol displays?

    Hello, ES! I am trying to upgrade the B&W LCD 800S display and Lishui 36V controller currently installed in my M2S All Go Carbon with 350W Bofeili mid-drive motor. I picked up the Bafang DPC-18 display, which communicates via the UART protocol. I hoped it might work with the Lishui...
