I would like something for trail riding,
I haven't ridden a surron, but I think I'd like one. It's an actual "dirtbike". Dirtbike pegs. Dirtbike seat. Dirtbike balance.
I own a pretty fast downhill bicycle frame modified with a MXUS 3K and Nucular 12F. 11kW peak. 100km/h. It is a lot of fun.
BUT, its still a bicycle, with a bicycle seat, and a big fat hub motor in the back wheel. Fast as fck in a straight line, but in my opinion, hub motor bikes handle like shit. It's just physics. The rear wheel is nearly 1/2 the weight of the bike. There's no way to fix such a massive unsprung weight in the back wheel. No amount of suspension tuning will make it better than a traditional chain drive. No matter what madrhino says, his bike might be the best handling hub bike on the planet, but still not better than most traditional drivetrain bikes. It's just not physically possible. The ratio of wheel mass is very close to the sprung mass, so their natural frequencies are very close, which means that the transmissibility of force is very high = bad handling. Put simply, when the wheel hits a bump and goes up, it forces the bike up, and there's not enough bike mass to react and push the wheel back down. You make the spring harder to push the wheel down harder, but it also has the effect of pushing the bike up harder. You just can't "tune" it out.
Hub motors have a lot of good traits though. Simple. As mentioned, usually pretty quiet. Low maintenance. Decent power available. Relatively cheap. Easy to convert. Maintain the bicycle look for legal reasons, or for the use of high quality bicycle components. Satisfaction of DIY conversion. For these reasons, many people go that route, including myself.
But back to the surron. It doesn't suffer from that massive rear wheel mass, and also has a traditional motorbike seat, so you can slide/move your weight forwards and backwards easy like on a traditional dirt bike. So balance is much better.
So based on my history of riding dirt bikes, and the fact that a surron is more like a traditional dirt bike, if you don't have any legal issues riding the surron, then that's what I'd suggest.
And wrt controllers, if you go on the Nucular "Telegram" app chat, you'll see a lot of happy customers running their 24F on surrons (with upgraded battery packs).
