Dualtron Thunder 2 stem snapped while riding, also had multiple defects which were never fixed. I only got the runaround for over a year!
I spent over $5000 on a Dualtron Thunder 2 + EREXX steering damper + EREXX stem clamp + fingerprint scanner + other accessories. My stem snapped while I was riding, as it has done for many other Dualtron owners too (I wish I researched common Dualtron issues BEFORE buying it because all these stem breakage issues are very well known and easy to find, and go back like +7yrs, only being fixed by a stem hinge redesign in 2024) My Thunder2 was defective from the beginning and I sent them over a dozen EXTREMELY DETAILED emails with pictures and video showing all the problems, and all I got was the runaround for over a year! The stem wobbled between 1" to 3" forward/backward with stem clamp fully tightened. Both wheels were severely off balance and/or out-of-round so they actually bounce enough to leave the ground when going over 40mph. The tires were both inflated to over 60psi from the factory when they are clearly marked as "45psi MAX". They never offered to have a local shop look at any of the defects/problems. They never offered to return the scooter to repair or replace it with one that worked correctly. They literally gave me the runaround for over 1yr without fixing ANYTHING that was wrong, and here are the best two parts: 1. After it was out of the 1yr warranty they finally said I need to pay hundreds of dollars to fix the defective parts myself! 2. I ended up buying the parts from them 2wks ago and paying hundreds of dollars (so I can sell this piece of garbage scooter) but they held the parts hostage until I removed a negative review I left on one of their YouTube videos! If you want this stellar level of "quality" in a multi-thousand dollar scooter, and also want this amazing caliber of "service" from the company when you find out it has defective parts and dangerous issues, then you should definitely get a Dualtron...good luck! Check out all the other reviews here and any other sites and you'll see this isn't a 1-off event. It is standard for them.
