Re: Custom spider- need advice on type/grade of steel

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...

Re: Cycle Analyst V3 preview and first beta release

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.

Re: Cycle Analyst V3 preview and first beta release

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...

Re: Cycle Analyst V3 preview and first beta release

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 ...

Re: Cycle Analyst V3 preview and first beta release

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.

Re: Trying to understand controllers and high rpm small wheels...

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...

Re: Cycle Analyst V3 preview and first beta release

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.

Re: Light dirt bike, QS 120 70h motor, custom steel frame

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 ...

Re: 9c hub in 26" rim super slow wind with temp sensor

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...

Re: Light dirt bike, QS 120 70h motor, custom steel frame

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...

Re: Real-time cells voltage display instead of BMS

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.

Re: Real-time cells voltage display instead of BMS

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...

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.
