I bought a computer( cat eye) for Terratrike path 8. But i didn,t have mount for the sensor and i called terratrike people and they immediately sent me one in an envelope for free( in two days). now my cat eye computer works perfectly and i clocked on a flat terrain maximum speed of 19 mile/per hour on fourth gear. I really like path 8, it takes some time to adjust the seat ( recline position) that is most comfortable. Now i enjoy my path 8 every day. Any suggestion from you guys regarding how to increase the speed of path 8. May be upgrading to 26 wheel will help a lot in speed enhancing. Any good suggestion to increase speed.
