Electric motorcycle riding mode calculations and Methodologies

Electric motorcycle come with sport mode, city mode and eco mode. All have different speed limits. Also they have different max torque vs speed relationship so that energy consumption is less and we get more range. So, I need the calculations regarding how to decide these riding modes( sport, eco, city) how to fix speed limits and corresponding max torque limits for electric motorcycle so that range of motorcycle will be more in eco mode, less in city, and min in sport mode
