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

Yeah I know about the ex1. But the largest cog is still hard up against the wheel which is where the chain line is the worst (with respect to wheel clearance)

So even though it's 8 speed it doesn't solve the chain/wheel clearance problem.

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

maybe 12-speed cassette with 4 of the inner gears removed, offsettting the cassette towards the drive side.

It would be a frankenbike anyways not something worthy of retail to consumers.

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

the issue is chainline... to get the chain past the big fat tires you need to move the motor out-ward, but since the motor is only 'so-wide' you end up shifting the whole thing to the drive side, which is a problem on the non-drive side... might be possible but I don't think you can just drop in a n...

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

The idea behind the m600 is not all-out power.. Bafang make the ultra 1000w for that. Its intended to be a light (er) weight but go-anywhere motor.

Its intended to be compared with the Bosch, Yamaha and Shimano ebike drives.

I'm doing that as well with my design (but I'm getting a part from Digi-Key) one day I'll get around to finishing it and actually building one up

It looks like a CAD shot of this company's bike: www.fangbikes.com Apparently the Carbon mould is completed, and prototype frames are being ISO standards tested in May so real bikes should be available from June/July on wards.

Looks like this one:

Re: GNG X1-pro 3000w

That is 14S, 5000mAh, so 51.8V nominal. Enough to power the drive certainly, but I would want two of those sticks... at least.

have you got the orientation of the board correct?? note that when you flip the board over, assuming your layout shows Pin 1 as Top-Right on the Brain board (the square pin), your Brain Board pin 1 actually goes to this pin shown... so note that there is a PIN translation, and you need to be careful...

Re: Lebowski's motor controller IC, schematic & setup, new v2.A1

I think Bas mentioned earlier, that it is a safety mechanism at startup so we don't blow stuff up.. it's also if there is a short, not just if the motor is moving.

Re: My RC Mid Drive with Single Stage Reduction

I have to add to this, the torque sensing factory bikes are very natural "super Legs" you don't actually notice that it assisting you, until you turn it off, then pedal up the same hill... The downside is that you are still the one doing the work. there is no "throttle blip" over obstacles, if you d...

Re: Lebowski's motor controller IC, schematic & setup, new v2.A1

Also I was thinking of making isolated phase feedback reading on my board. So from what i see controler brain needs only digital signal with less than 2.5V meaning 0 and higher up to 4.9V meaning 1? Would that work? Or is there some rising edge function? I could make this work with some isolated ci...

Yep. I used a lab power supply to test my Lebowski controller.

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

I haven't actually ridden the m600 yet. But I owned and thrashed the previous 350w torque sensor model on an enduro bike and I am confident that it was "right up there" with the likes of Bosch and Shimano. The torque control was excellent, very natural feel, good torque and much quieter than the Shi...

no bearings either, you can see some sort of plastic bushings on all linkage pivots. I doubt it will last considering the places you can go with an ebike. There is a plus side.. If the bike is cheap enough, rip the drivetrain, bars, grips, gears, wheels and M600 motor off of that frame, and put it i...
