I just completed my first ride on the Ultra Bee. But I've had a Light Bee for 6 months and rode almost daily.
Update 11072023:
Now that I've had the Ultra Bee a little bit longer though, my perspective has changed some. The Ultra Bee is a much better machine in every way possible. It's a real motorcycle with real motorcycle parts. Also it's a much better bargain than the Light Bee, you get a lot more for your money with the Ultra Bee. I think the Light Bee is overpriced. I thought I would continue to ride the Light Bee daily, and the Ultra only on weekends. I'm finding though that I want to ride the Ultra daily, The Light Bee will be regulated to bicycle trails, sidewalks, and other places that bicycles go. Any serious road riding, or trail riding, I'm taking the Ultra Bee.
