At about 1k miles on this beast. I can't speak for the insides, but as far as the way it runs, its superb. The 3500W Motor and 83lbs weight of the EUC takes some work and technique to master, but with a bit of practice you'll be able to accelerate like a rocket. Easy to go down stairs, on bumpy roads, curbs(up and down), pretty much the most unstoppable electric device out there, I go places no Sherman rider or non-suspension rider would want to go. Also has some really pumping speakers. The Begode Stock pads are decent but you may want an upgrade, and also spiked pedals feel essential for more control.
Three things I don't like, takes a bit of set-up to get the suspension find tuned, not a big fan of the boxy look, 83lbs takes some getting used to. Don't buy this EUC if your not prepared to work with it, gonna take 100 miles of practice to get used to the weight in my opinion. I weight 135lbs, would recommend this EUC for bigger riders as they will be able to get more torque out of it.
Lots of videos on my youtube and IG, if interested.
