I am impressed with the build, craftsmanship, and strength of the H8. The selection of gears available is a real plus compared to the other bikes out there. What brought that 18 year old feeling back again and a smile wrapped around my face was the speed. Hold on. Though I truly will only use that speed rarely to give the bike longevity, it's a hoot. The only thing I hae an issue with is the mirrors don't fit, with or without the spacers, it will have to have the type that go into the ends of the handle bars. I bought an extra battery at the time of purchase, just wished they had a coupler or blender to go with it. Other than that, I hope next year, a 4000w 60/72V model is available!
