Every Spoke bike shows your power in watts and your zone as a colour. You don't need to understand the numbers to use them, but here's what's going on behind the screen.
What FTP means
FTP, or functional threshold power, is roughly the highest power you could hold for an hour. Your zones are slices of it: Zone 2 is 56 to 75 percent, Zone 4 is 91 to 105 percent and so on.
Why zones beat numbers
Two riders in Zone 4 might be pushing 150 and 300 watts. They're working equally hard. Zones let a whole room follow the same cue, whatever their fitness.
Zone 1, blue: recovery
Zone 2, teal: endurance
Zone 3, amber: tempo
Zone 4, orange: threshold
Zone 5, pink: max effort
How your first rides set it
You don't need to take a test. Your first three rides estimate your FTP from your hardest efforts, and the bike updates it as you get fitter.
