Mine work fine from walking speeds. They produce more light at higher
speeds, but at slow speeds you don't need it, because you're not
moving fast.

That's my experience too. The last time I recall not having enough
light at low speeds was in a dark campground with a pre-halogen dynamo
light with lousy optics. That was about 1980, IIRC. With the modern
LED dynamo lights, it's never even come close to happening, even at
walking speed.
