One thing that happened to me, and I see it going on here at least in the form of upgrades for more power and distance. These ebikes are just so much fun that they leave you wanting more and more. To satisfy the urge for more, I ended up getting this Black Kawasaki Ninja 250. Great MPG, huge fun, tons of power, and I can still enjoy rides on my Ebikes in their stock condition. I really don't think I would have got the Ninja if it weren't for the Ebikes reminding me how much fun biking is. I still use the Ebikes just as much, the Ninja will take away some car usage.
