I would never take a brand new board. Too likely you’ve overlooked something, no time to break it in first and make sure it’s not going to fail immediately.
You can increase your gear ratio to improve efficiency. Either a smaller motor pulley or a larger wheel pulley. It’s equivalent to using a smaller wheel diameter or lower kv.
I know I shouldn’t but this one is more water tight and I’m spending a week in Scotland so got carried away with dream lol I knew it while I was doing it based on the spares and tools I was planning taking , taking half the crap now and just my 2 essential boards
This “or” here is deceiving – I used to think that as well, and the math indeed says that.
However, in real life, the higher Kv motors are better because you can run them unsensored and they startup SO MUCH EASIER than a lower Kv motor from a dead stop.
So a 190Kv at 15/40 is better than a 160Kv at 16/36 even though the math says it’s a wash.
Thanks flasher, I already did some hours of reading there but I got lost by all the different ways to do it and techniques etc etc I will try asking there, thanks
i’ve ridden hummie hubs unsensored in the 75kv range… i think if you rewound the same motor to 190kv it would be harder to start since it would put out much less torque for the same motor current.
i think the ideal setup for me would be 4 hubs at 91kv with 120mm tires, 12S and 60a battery limit per motor. in theory this can sustain +50mph on a 35% grade. 14mm steel through axle.
@b264 Taking things a step further, no matter what kv you choose to wind a motor with a given copper volume and winding style, it puts out the same torque for the same copper losses.
