Just the other day took delivery of an Ayro 311 ( https://ayro.com/ayro-311/ ) all electric autocycle/golf car/reverse trike, and something went horribly wrong at only around 20 miles on the speedo! And it had about 16 miles on it when I got it. All was fine for a few miles, and I even had it at top speed of 50, but shortly after that, there was a horrible mechanical sound, and then I lost all power. Something mechanically broke in motor or transmission. Would not respond to accelerator pedal at all in forward or reverse until I manually pushed it a little bit while in gear, and then horrible impacting/grinding sound resulted with accelerator pushed. The dealer apparently contacted the factory, and determined it sounds like a bad motor, and factory is sending them a new one. They'll come get the 311 when it comes in, unless they decide to attempt to swap it out at my house (about an hour away from West Palm Beach dealership). I hope "when" the Elio comes out y'all don't have similar issues!!! BTW: my 311 is serial number 34.
