The MTen4 is a deeply fraught piece of equipment. With a few minor manufacturing improvements, it could be great.
1) fix the battery cable issues. Probably sorted in newer versions
2) waterproofing. As manufactured, the MTen4 will fail in the presence of mist. This is easily remedied with a tube of rtv silicone, but begode should be doing this in the factory
3) stronger axle. At 220lbs, I'm right at the weight limit, and I've already broke one axle. I won't be doing any curbs or drops on this new one
It's still just about the most fun you can have on one wheel, and perfect for urban environments. I wish other manufacturers would make similar scale wheels.
