Endless Sphere

Groovy. Looking forward to it!

Yea, I was just going to say, it's 81.

I still myself attracted to the idea of a mid drive setup with a DD hub in back to be used as a "coaster brake", particularly on long descents when heavily laden. The amount of current to the battery could be regulated by a rheostat and a big ass resistor if needed.

Better tell your friends, then. The MOQ is 20.

From the Ruff Cycles web site: "PORUCHO - Toot-f***ing-Toot...imagine yourself as a young storm trooper swaggering that thing at walking pace down Hollywood Boulevard with a fine female spread legged on roller skates over the back wheel grabing firmly with both hands to your oiled up trapezius muscl...

Probing a little deeper seems to reveal that this is quite likely one of the first incarnations of the BPM motor. Also it just occurred to me, having not too long ago "crossbroken" an earlier model REAR BPM, that it did indeed have a rather oversized stator carrier [EDIT: side cover] bearing, just a...

@Markz I'll have to catch up with you on that another time. I'm all over the idea of mid mounted hub motors these days. @MrNotEnglish You could try asking this guy if his bracket will fit the 1016 you have. But doesn't yours come with a foot welded on with four bolt holes? If so, just use U bolts me...

Oh. Well I'm still considering myself partially right in thinking it's a form of integrated theft prevention. HA!

There doing something similar out here too. Minus the electric assist, but minus the docking stations too.

Old news now.

Why do they have to look so dorky?

I made an account on alibaba just so I could ask about it. No response yet but they want to see my 'business card' and I don't know wtf I'm doing.

It is kinda cool though, huh. Just like in the drawings but nothing like anyone actually ever has.

Right. I knew that bit. I should probably amend the topic to be a bit more specific.

I actually figured as much.... waaaaay after the fact.

I still think someone should buy one of these though.

So, sorry, that first spreadsheet is used to calculate the wheel diameter to be used in the ebikes.ca simulator for mid drive motors?

Is that right?

Looks like a BPM but I've never seen one that doesn't have the cable coming out the axle..

Any thoughts?

Well for what it's worth. I'm still in the process of building my first ebike, but it sounds like we have a very similar idea of what we want to accomplish. Depending on what kind of motor you're using, there may be the option of driving the LEFT side of the BB with another crankset. The caveat the ...

Hey, mechhead, how is the conversion going so far?

I'm having a hard time telling from the pictures if individual chainrings can be swapped out on the M371 but it looks like they can't. My gut feeling is that you're gonna miss not having access from the big ring to the wheel. An old 10 speed crank set might do you better. You'd only have 1x7/8/9/wha...

Derp. I think I knew that and had it backwards.

Note to self: Outrunners have the spinny bit on the outside a la DD hub motor. Inrunners have their hamster wheels inside like the GNG.

There. That seems easy enough to remember.

Never had one. You say "give them up" with such a sense of permanency. What's wrong with outrunners, if you don't mind my asking?

Oh my God!

The general profile looks the same, I agree, but there are differences. This motor appears to be brushless, for one. I almost bought the stupid thing last night, cause I need another project to spend money on...

You should probably buy it and tell us what it's like. I've been eyeing this one up a fair bit myself lately. 13.4 N.m seems a little wimpy, though. And yea, that motor looks kinda familiar...

Switched the ground with the sense wire. All good now.

Thank you for your help.

Ah. I suspected as much. And no, you're right, I should have also mentioned that I am connecting to a generic controller without a CA.

Thank you for your prompt reply. I'll be sure to report back after I've checked into this.
