The fixed P20 folder runs 65 and 70 gear inches which is great for spinning along in the 30 kmh range and the new 3 speed P20 runs a gearing of 45/65/80 gear inches which makes it a little more versatile.
I rode the 3 speed home today and took a dip through the valley which meant I had to climb back up nearly 800 -900 feet on grades that went as high as 18%.
It was a bit of a hammer fest.
I removed the dual drive from the 3 speed and am thinking I may upgrade a few parts and reinstall it to give me that nice 6 speed gear range with 25% jumps and allow me to do more seated climbing.
