Pretty much have the bike dialed in now with the 24" tire. able to get to a nice cruising speed of 38-40mph in 7th gear.
next i'm going to build this for the bike: DIY LED Tachomter (RPM gauge)
takes a voltage input and converts to an led bar graph.
i'm thinking that since the white wire voltage increases with rpm, i could use the input from that to use as a signal.
