I'm hoping someone can help me out here. I have a mid 90's Dyno beach cruiser that has a Nexus 4 speed hub. If you're familiar with the hub, it's geared very tall, like 1st gear is a 1:1 ratio, then 2, 3 and 4 are all harder to pedal. Since there are a ton of hills near my house I wanted to improve the gearing by swapping the one piece cranks over to a 3 pc set and just use the granny gear up front. I've done this, but the chainline is somewhat off, and it looks kind of funny with only the granny gear. The bike rides fine, but is there anything else I can do? The hub already has the largest cog available, 22T. I'm not sure what the front ring is (small!) but I like the gearing as it is now.

TIA
