Buying bikes are the hardest part. For career power requirements goes higher. One bike costed 250000. And we can only earn 1000-1500 points in endless mode. I've to 2500 games to buy a bike and loose all my money for it. And then after games in career mode in can only earn upto 30000 maximum then again ive to play endless or other modes other than career to buy another bike bc power needed goes higher and again ive to play 3000 games to buy a new bike. Kills time that makes it boring.
