Endless Sphere

Would probably make more sense to see it all assembled in the model but I believe you. I wanted to speak up if by chance it was an error and you were going to pay a bunch to have one made. I agree with the suggestions about trying to make it flat so it can be waterjet or laser cut. That is way cheap...

Whats up with that hole on the bottom left breaking through the wall of the raised ring?

I think they default to 1mohm when you reset them. My 25 amp controller shunt is 4.66 mohms. That is very likely what happened.

Sounds like you might not have your shunt value set properly in the CA setup menu. If you are running a grinfineon controller then the shunt value should be written on the bottom of the controller. It will be some value expressed in milliohms. In the CA calibration menu there will be a shunt value s...

I read the CA manual for wiring. Id like to do pass thru wiring with the grin shunt and have the throttle wire ONLY going from the shunt to the controller green wire. But at the handlebars, do I plug the throttle directly into the CA unit controller connector with ALL 3 wires as normal or only red ...

The red V+ needs to be connected to your battery positive wire. The main controller positive terminal Is a safe bet. If the controller turn on wire comes straight from the battery then I suppose that would work as well.

Yikes! $6500? Are those fatbike tires on narrow bicycle rims? The proportions look a little weird as well. Its always nice to see more options on the market but that's almost enough for 2 Sur-Rons! I like the general frame design more than the common sheetmetal box ebike frames. How did you happen a...

The controller only cares about electrical RPM. You need to know the number of magnets in the motor to calculate this. E-RPM is the number of magnets divided by 2 times the motor RPM. I have a scooter motor with an 8" tire that has 30 magnets. At 1000 motor rpm that would be be 15x1000=15k eRPM. Hop...

Yes. The CA3 has no means to limit anything unless it is between the throttle and controller.

With your throttle wired directly to the controller your CA is just a fancy information gauge.

Everything I can find is $40-50 for shipping. I can promise you this anchor is not worth that to ship. I know I'm shooting my own sale thread in the foot here but here in the US we shoot everything In all seriousness its really not worth it.

It hadn't occurred to me that the fork length dictates the overall dimensions but that makes perfect sense. The issues you had with the Votol sound frustrating. Thats the kind of thing I was afraid of. Sounds like you got through it. I like tinkering with stuff but I get so little free time to work ...

Its from the old days when controller choices were more limited and all the hubs had small phase wires. Over volting was the easiest way to get big lower with little money. As long as you are not trying to go 35mph I still think this is the best way to have a powerful bike with a $40 controller smal...

How well setup is the Votol when purchased with a motor? Does it require that you learn how to program it or is decently rideable from the start. I ask because I would ultimately want a Nucular to Pair with a qs but given the wait time and the low price of the Votol it would be a nice temporary solu...

Rear.

Cant believe I forgot to say that in there. Sorry.

I cant speak for all cheap cell monitors but with the cell log 8s disconnecting just one wire to turn them off still resulted in uneven drain on the cells. The only way to prevent the drain was to totally disconnect the unit from all the wires.

I am trying to put together as many frame options as possible and Futr beta is pretty much perfect ish for my taste and battery size requirements, however, the price for a new one is prohibitive at this stage. The Beta is a bit of money but you need to make sure you are being realistic about used m...

The good old cell log 8 has been discontinued. This looks like a nice replacement assuming they get them back in stock. It does LiFe and balances which is cool since the old cell log used to pull the cells out of balance over time. Its nice that you'd only need 3 instead of 4. https://www.progressiv...

Beautiful work! It looks really tough. Excellent color choices as well. I am curious if you will get any side to side wobble? The vertical sheetmetal plates That join the swing arm to the main frame box look like they could use some bracing between them to prevent it from racking when viewed from th...

Is the 22 tooth Freewheel large enough to drill through to bolt a larger sprocket? Just ignore the teeth and use the material as a flange. Ive also seen people run bolts through at the root of the freewheel sprocket teeth since they are round. Its like half a hole so the sprocket cant spin because ...

Could you post a list if the motors you have successfully programmed to these controllers? untill now: QS 205 QS 260 QS 273 QS 138 Xofo mid drive Bafang mid drive Mxus 3K Mxus xf40c 1000w Mxus 5k Cyclone Bafang hub motor ME 1507 Zero 75-7 Bionx hub motor There is no motor that I had problems with m...

I impulse bought this stuff a while ago and don't have any use for it. Save it from the scrap pile! If I have to risk my life to go mail it then I might as well get enough money for beer. Items are pretty rough looking but maybe someone wants them. The golden motor I believe is a BLT-500. I took the...

Hello This has been sitting around too long so I should probably sell it. Its in awesome condition and has very little use on it. Its always been stored inside. Its the slowest winding that I know of at 12 turns. Its perfect for a cargo bike or a low speed cruiser. If you have a high voltage setup l...

Slipper clutch is set to break away at a particular torque. It is not an on off switch and you likely wouldn't even feel it working. It just slips away the extra torque while still transmitting some. You DO NOT need sine wave or FOC for smooth takeoff. Those are neat and more refined control strateg...
