    Lower Power from a Cyclone

    I am thinking about using a Cyclone (mini or 3000w) to replace a 1000w front hub drive. I would like to cut back the power to about 1000 watts for safety reasons. I will not be the only one riding it. Scott from Luna sales says the Cyclone controller is not programmable and there is no way to do this. Is this correct? Can I dial down the stock controller? Alternatively could I use my existing controller (1000 watts) and match up the wiring? Would the motor overload the controller or would the controller simply limit the amps going to the motor?

    Thanks

    This actually is possible--but in a more indirect way.

    With the Cyclone Bluetooth controller option, you can indeed decrease the power-output settings--to "soften up" your Cyclone--but no, you cannot just tell it "limit to 1000W". It isn't that simple.

    The (stock) Cyclone controller doesn't work in "watts" -- but in amps. Because it can operate at a range of voltages 36V-72V; its "max" 60A won't add up to the same number of watts--depending of course on your system's voltage (Volts x Amps = Watts).

    I have the 4KW Cyclone (it wasn't much more money--and had a higher efficiency-rating). It's WAAAAAAY more power than I need, and to save myself constant parts-replacements, I've turned it WAAAAAAAY down from what it was stock. So, the long answer is yes--you can adjust some settings within the Bluetooth Controller's Android App, if you wish to "soften" things up too. Comparing your amperage draw before and after adjusting, you will be able to notice that amperage can indeed be limited by changing the settings.

    If you persisted, I believe that through that Bluetooth Cyclone Controller's App--by tinkering, and monitoring and adjusting, and testing again and again--you could probably fine-tune it down someplace close to "maxing out" at approximately whatever amperage (when multiplied by your system voltage) came out to about 1000 Watts.

    Having said that, I also believe you'd be better off just turning it down until it "feels" right--rather than concerning yourself so much with the precise number of watts. A mid-motor won't behave exactly the same as your old hub-motor did. The Cyclone uses the bike's chain and gears--so that's a whole other set of mechanical advantages at play--while a hub-motor's gear-ratio (if a geared hub) is generally fixed (though there are a couple two-speed hubs out there on the market). Point is, for these, and probably dozens of other reasons, a linear comparison of 1000W systems--mid-drive versus hub-drive--isn't likely to yield parallel performance. I think it's too much of an apples and oranges thing. I like both types of systems--and I'm crazy enough to be using both types on the same bike!

    I hope that helps--but maybe I've just muddied the waters.

    Best of luck with your project!

      I am looking at adding cyclone 300w midrange for hill climbing gear ratio advance torque. My little fat bike already has rear hub motor that works. Going to add that cyclone with it's own controller/its own battery/its own throttle switch/ pretty much making it a two powered bike. Only using the rear hub for emergencies&lighting because it's already set up on programmer. So I wish you the best on your conversion, I am 60 yr old man&want more power not less. I think your conversion sounds like you thought this thru a lot, so I believe you succeed. Not very helpful but at least I found someone in similar circumstance for a model. Good luck
