It made sense to me.
I actually just bought one. Got the idea from this thread. I am working on a friend’s all blacked out beach cruiser. He lives in a flat area (Richmond VA) and mostly rides to the local breweries . He was complaining that he needed his bike to go faster. Well for some reason it came new geared ridiculously low. Like granny gear. It is a single speed coaster brake. Bought during Covid, so maybe it was due to lack
of parts.
Anyways, I am going to re-lace the rim onto the SA kickback and use a smaller sprocket. Goal is to have a fast and 38% faster gear. No cables!
I am really excited about this. Just got the hub yesterday and still need to calculate spoke length.
If this goes well, I may build another.
Thanks for the idea!
