It's natural for everyone to focus on how fast this bike is, but that's only a small part of this bikes, or any powerful electric bikes riding experience. What's eye opening about it is how powerful, and well controlled it is just off the throttle stop. At extremely low speeds in other words. You might be thinking what a waste to have so much power, and only be using a tiny little bit of it, and that would be true for an ice engine, but that doesn't apply to an electric.
We're all used to ice engines that have the least power off idle, and build to maximum power somewhere up near the redline. It's an entirely different feel when you have full power from rpm 1, all the way to top speed. That's what people that haven't experienced a powerful electric bicycle are missing.
Think about how your china girl would be if it only had the power it has off idle, but all the way through the powerband. What a dog that would be. But china girls actually do only have doggie power off idle, and you do have to rev them out to get to the real power. An electric is a totally different animal. It comes off idle with potentially full power at hand from 1 mph. You have to use a steady throttle hand to keep from blasting off.
On my bike it takes a while to get used to operating the throttle without getting whiplash at every stop sign. It's why I'm very reluctant to let anyone ride my bike, because if you're not used to what's fixing to happen you're going to have a high provability of dumping it in about 3 feet.
Once you're used to it though, it makes for a very satisfying feeling riding even at very low speed, because low speed still feels like full power. You don't have to go fast to feel the power. Going fast, and feeling acceleration become separated, unlike an ice engine where it's more hand and hand. It's like having the broadest powerband you can imagine, which in fact it is. It's extremely addicting, and one of the reasons why the electric riding experience is superior to a ice.
