What makes a Deluxe lower than a Heritage? Is it the suspension or the frame? We are considering a different bike for my wife. She is on a Dyna Low Rider now, but has difficult on long rides. I am thinking a Deluxe or Heritage may be an easier ride for. She can reach the ground on a Heritage, but can reach much better on a Deluxe. But if the Deluxe is a harder ride than the Heritage, that would probably not be a good choice, even though it is lower. She tried a Road King Classic. The ride was great, but it was too much of a reach to the ground. We did wonder if a Road King was lowered enough, how that might be. Any comments will be appreciated, and thanks in advance.
