I'm planning to upgrade my wife's Boardwalk SS hub to internally geared hub. Which hub do you suggest and how much do you think the bike shop will charge? Originally thinking about a 3-speed hub to keep tings simple but scared that the first gear might not be light enough top get her up hill.
We are just leisurely riders who go at a fairly moderate pace and converse a lot while riding.
Also, most the hubs that I have reviewed online come with either coaster brakes or roller brakes. Can someone please explain to me what roller brakes are? Can't seem to find a good definition online. Definetely don't want coaster brakes.
