Re: Samsung 40T - 35A 21700 Li-ion battery's capacity test

I see the problem, but I guess the whole point of these tests was to show the different performance at different current draw. His setup didn't change, so we can still get useful information from the results. Technically perfect? No.. but useful.. yes.

I shouldn't laugh but that's actually pretty funny. They make moulds, tools, carbon parts, but can't solder the red wire on properly... The plus side is (because there's always a plus side)... You can now fix it properly and do the other wires while you're at it. And you will know that it is all don...

Re: GNG X1-pro 3000w

maybe the drive gear is smaller on the direct drive vs the chain drive, thus overall same ratio? I don't know for sure but this is certainly possible .. and makes sense.

Re: Wayne’s Dengfu Carbon Fibre FS 27.5” with Bafang M600 (throttle also)

From your description, it seems to me like the issue was at the XT 60 connector (ie if you cut it off, then measure the wire end to the pins and it is ok, the issue must have been with the bit you cut off) was there any way to inspect the rear of the XT60 or was it gooped up? It's possible they have...

Re: Wayne’s Dengfu Carbon Fibre FS 27.5” with Bafang M600 (throttle also)

My guess is a bad solder joint on the back of the XT60 or down at the connection point on the receptacle. Probably easier to open it up and re-solder it, rather than waiting weeks for a replacement??

Re: Using crankset with ANT+ powermeter as PAS

My first thought was a bolt on load cell. With a Bluetooth link to a DAC for 0to5v output. But really you also need to know rotation. Torque alone doesnt cut it. What if you're standing on the pedals? Of course you could put a sensor on both crank arms but twice the cost and complexity. Maybe it's b...

Re: Using crankset with ANT+ powermeter as PAS

Sorry to dig this up.. but I've been thinking about this.. There are many new power meters on the market, I saw one the other day discounted to around $200AUD. which would make an awesome Torque based throttle. Before i get into it, has anyone got any ideas like this, or reasons why it wouldn't work...

Re: Feiwel 27.5+ Bafang M600 Dual suspension emoutain bike

Geometry looks pretty shaky
I agree, the geometry looks very long and steep. Also another gotcha, is whether they use bushings or bearings in the rear linkages. they don't always use bearings by default.

I'd pass on this one.

Re: Wayne’s Dengfu Carbon Fibre FS 27.5” with Bafang M600 (throttle also)

Hmm I can't see any reason why the battery will have any impact on the use of a throttle. It is true that the battery will have CANBUS and UART connections and +5V for a total of 7 pins, Maybe the Throttle is getting the +5v supply from the battery...

That's not the bafang battery it's a battery like Frey use..

I heard that Bafang were making changes to the battery to comply with EN15194 and that November they will have the batteries available.

Re: Carbon Fiber e bike with Bafang M 600 mid installed with throttle

I visited the Enwe factory in China and saw this bike. looks good, I did not get to ride it though as it was a 3D printed model prior to them finishing the mold. It is the same as the Dengfu bike..

Re: My Bafang Ultra Mountain Bike! Frey AM1000

Where did you read this? I'm interested to learn more. I think the EX1 is a great concept. Strong, simple. Etc. Double shifting is a problem with 1x11 or 1x12. Who really needs 11 gears on an ebike.

Re: Dave's 80:1 RC mid drive kit build log

well it's funny but when i first asked the question, before I saw that you tube video, it was actually the sound of the drive that first got me thinking about the similarity between tangent and TQ..

Anyway, it is nice to see various solutions to the reduction problem, all with great success.
