So I bought a V11 during the prime day sale for $1600, which I still think is a great deal. However I learned the hard way that you can't push that wheel in "fancy" mode. I tried to ride up a roughly 4 inch high curb at walking speed, and it fried a mosfet. Fully dead, can only get power to connect to the app while plugged in. It has rolling resistance, which means fried mosfet.
I returned it to amazon, no questions asked, easy-peasy.
If you have a V11, DO NOT USE "FANCIER MODE" (which lets you pull more power and hit 34mph), unless you want to fry your device. If you don't believe me, youtube "overheat hill V11" to see how fragile this thing is.
So I put a bid on a craiglist brand new S18 and after watching lots of videos on it (including overheat hill) I'm convinced the wheel will cut out before it allows damage to come to the control board.
This setback hasn't deterred me at all. EUC riding is the most fun thing ever, and I cannot wait till I pick up my S18 tomorrow.
Dirt trails terrify me. With only one wheel, it seems easy to lose traction. I know it's not really like that, especially if you get a knobby tire, but it's an irrational fear. After all, the only accident I ever had on an EUC was hitting a gravel patch on pavement and high-siding.
But you should absolutely do it if it's not something that freaks you out. It looks super fun! Just be sure to gear up. Lots more things to hit in the woods.
