I loved the second game in the series and beatable without money or hours and hours of grinding to try to earn enough money to get the next bike. I spent about 4 hours playing in my first week. Each bike costs wayy more to buy than the previous one, with rewards remaining pretty much the same.Each race gets you about $100, the next bike is 15000. I am pretty much out of coins. I think between the first 3 bikes I have earned just that. and have spent it on mostly required performance upgrades.
