I've test ridden countless bikes. Internally geared hubs are beautifully crafted pieces of engineering, hiding their complexity in a simple cylinder with the ability to shift at standstill. But, their big downside is you cannot shift under load. Trying to shift while pedalling with a medium effort (or greater) just leaves them stalled in the gear you're currently in. You have to ease off a little, and then they snap into place.
I've searched high and low for a seller that has any bike fitted with a Nuvinci hub, and have come up short. I'm desperate to test drive one. I want to buy one and retrofit it onto my Trek Lift+ (pedelec). The Nuvinci is apparently very content to shift under any load, at any speed - and to an any ratio you like on an infinite spectrum.
