FastTrack Bikes, Inc. is thinking of developing a new composite road bike. Development will take six years and the cost is $ 199,000 per year. Once in production, the bike is expected to make $ 297,128 per year for 10 years. The cash inflows begin at the end of year 7. Assume the cost of capital is 9.2 %.

With costs remaining at $199,000 per year, how long must development last to change the decision?
