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

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...

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...

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...

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...

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...

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...

More photos of modding the Sturmey-Archer 5-speed IGH to take the Rohloff Veer belt drive sprocket:

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...

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...

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...

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 :)...

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...

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...
