Well, it’s a bit ironic, because Onloop himself has blurred the lines. He sells mass-produced completes. “Mass produced” is a bit of a stretch to say since he’s a one-man show (mostly), but there are models that you can choose that are made in multiple copies. Enertion is the same as Boosted and Evolve, except he sells kits and parts as well. In terms of customization, Enertion gives even less than say, Mellow Drive, because you can get a Raptor deck in all shapes and sizes as long as it’s rigid black carbon.
@laurnts, we agree. Numbers can lie, but gather enough of them controlled conditions, and they tell a better story than “my board can do a decent hill.”
I do. My e-skate isn’t a longboard but my snowboard that gives the same feeling not only when there’s no snow, but when I go flat or uphill. That’s what I tell people who say I’m lazy, btw: yeah - you try pushing your skate at 40 kmh uphill.
Also, you forget the brake. I accept that I’m a perfectly irresponsible father and bad longboarder who can’t slide so can’t really bomb hills, but I love taking steep downhills while being able to control my speed. My 10 year old daughter, who can’t kick or footbrake well, followed me down a succession of 20% curves and we both had a ball. We kept the speed down low on the knife’s edge between safety and thrill.
That’s backwards. Highest torque for all electric motors is at V=0, which is why a Tesla will slaughter sports cars out of the gate, but lose ground later on. The torque curve then drops gradually until the field weakening phase, where it drops drastically until it hits maximum rpm. The beginning of the field weakening is called the max rated speed.
I agree with you that torque tells a better story than hill grade, although the latter includes a bit of legal liability in there, i.e. the product can climb steeper hills, but will probably overheat and kill your motors. Still, a easily understandable and more precise middle ground might be nice. When I just see “Climbs hill grade 15%” I assume that they mean “it can carry the max rated load up that hill for an indefinite period of time without overheat, regardless if there was a running start or from a dead stop”. I’m pretty sure though, that that’s assuming much too much.
So, back to torque. Mellow published their torque curve. It’s a calculation, which still makes it a claim, since it was done before they setup their testing rig. The fact that torque doesn’t change until 40km/h is mind blowing. You know how you have to brace yourself when hit the throttle? When I did a testride of the board, even up near 35 km/h, I’d get that exact same kick. Crazy.

I’m curious about torque curves of other motors perform so I’ll make a new thread though…
