    [USA] Will Tariffs come about and lead to higher priced ebike parts

    That was probably 30% plus UPS import handling fees so the best option he could have had as far as I understand it. If it was shipped via USPS I think it would have been 50% (or maybe $100 depending how you read the it). As far as I understand the difference if you pay the 50% or $100 that...

    [USA] Will Tariffs come about and lead to higher priced ebike parts

    As part of this orange man also got rid of the de minimis from China so you actually will pay more or possibly less (the wording is confusing) if it doesn't have a formal import. So what was free under $800 is now 50% or $100 although I'm not clear if that is the lesser or greater of the two...

    Newbie looking for confirmation she’s not crazy before first conversion

    You are generally on the right track but a few thoughts as well. 1. You might want to look at a hub motor instead, if your hills aren't that extreme and you're on paved paths and roads there are not a lot of advantages to a mid drive. Some will will be strongly in favor a hub motor but I think...

    Anyone knows where the "App Settings" in the VESC Tool?

    I think maybe your second attempt seems to be correct, how are you connected to the VESC? Looks like he used both a can-usb adapter and a VESC express but they might require different settings. Also there is a pretty good chance this will not work at all, they may have changed the unlock code...

    Anyone knows where the "App Settings" in the VESC Tool?

    You should make a new thread with exactly what you are trying to do, you haven't really provided any information on what you are trying to do. I guess you are trying to connect to a locked out VESC based controller?

    Should be there on the left, try restarting it?

    Phase Amps VS battery Amps, mosfet controller

    Interesting, I was curious what encoder the Nucular uses, it's an MT6816 but appears to be only set to operate in ABZ mode instead of SPI. I'm not really sure exactly what all the pros and cons of ABZ vs SPI, kinda assume they both require a solid connection to avoid noise and such. I guess SPI...

    Phase Amps VS battery Amps, mosfet controller

    I mean if your controller supports the resolve yeah it will be better, but you may have no issue at all running sensorless, it depends on many factors like the controller and motor. Although in a boat many of the sensorless issues are avoided. I would first try it sensorless and only keep the...

    Phase Amps VS battery Amps, mosfet controller

    I can see reasons why any VESC mfg would want short or no warranties, VESC due to it's expansive settings has some user issues. Lots of settings means you can run a wide range of motors and tune it well to suit most any motor but that also means if you don't know what you are doing (or even if...

    Hub motor off road riding

    Just suspension physics, hub motor means lots of unsprung mass, suspension performance suffers. Just the bumps on my driveway my hub bike handles pretty poorly while my mid-drive bikes are smooth. Possible to improve with suspension tuning I'm sure but you can only do so much. Also larger volume...

    Useing power supplies for charging

    So are you against the converted telecom PSUs already mentioned in this thread, they are often 1000s of watts adjustable voltage in the ranges you are looking for, much cheaper than a lab power supply. You can find them all over aliexpress, just search for like "battery charger 120v" or...

    Dual front motor torque steering - Possible to bias motors?

    The motors should have exactly the same torque if given the same current, motors have no forward or reverse. Unless the person that built it really had no idea what they were doing and those are geared hub motors with freewheels in which case one of them is literally doing nothing at all.

    Phase Amps VS battery Amps, mosfet controller

    Honestly I think most of these controllers that are rated for 500+ amps continuous would be fine if they were water cooled, of the controllers you listed I think only the 75300 would maybe struggle at 250A continuous. Yes in many vehicle applications some of these controllers are unable to...

    Phase Amps VS battery Amps, mosfet controller

    This is sadly the problem, controllers normally cost much more than motors and when you are talking about a used leaf motor which is already probably way way cheaper than it would have been new. This is also why high power motors are often designed around higher voltages so you can use a lot...

    Phase Amps VS battery Amps, mosfet controller

    I mean that motor is way way overkill but I guess there isn't anything wrong with that, most of these large controllers are designed to be plate cooled so a water cooling plate would keep them nice and cool. I'm not sure of the efficiency of running a large motor so far below it's intended RPM...

    Free energy machine

    If big oil has killed all these free energy inventors that's a pretty dumb play on their part, why would you kill them when you could kidnap them and steal their technology, surely there is more profit to be made from free energy than all the work required to extract and refine oil?

    vesc 75100 ESC Hardware and firmware open source

    I've got an encoder working on my 75200 but I had to remove the hall filters which I expect probably has to be done on all or most Flipsky controllers to get them to work.

    Has Anyone Tried to Print Large HTD 5M Pulleys?

    I haven't done it personally but I've seen it done countless times, you just need to get the tooth profile and spacing correct so they all mesh nicely but can always try again if it's off.

    2008 Polaris outlaw 525s ev build

    You can make the mount printed or laser cut and welded or other metal fabrication methods as long as you design it well. You could make a printed mount or a metal mount that are both poorly designed and break or vise versa. I've been using PPA-CF for a few things recently (I have some of the...

    This, also that much unsprung mass will make the rear suspension perform poorly.

    Spintend single 85V/240A controller

    I had the same thought, my guess is he looked at the mosfet's max amp rating vs the controllers max amp rating and thinks the controller can push more amps than it's rating. The answer is well that depends, can you push it a bit harder than it's spec, probably if you're careful but the FET...

    VESC Flipsky 75100 Pro V3 MSUX3k & 72CV 40ah HELP

    You should also see if you can tell what cells they are, if you can see any writing on the side, that would determine how much power you can pull from them.

    Hardware temperature control tsdz2

    The actual thermal conductivity of copper braid or foam will be a small fraction of copper's conductivity. If it will be more or less than pads depends on how much it is crushed and how dense it is but probably better if you fill it right up. Ideally you would replace all the air in them with...

    What motor and controller, dirtbike 60KW plus

    So is that you have a more or less unlimited budget or is that I'm never going to actually build this thing so it doesn't matter. My point is having some vague idea before you start picking parts with reckless abandon to how much it will cost, you could easily end up spending more than a Varg...
