Space Bikers is a cute and fun little game that manages to be kid-friendly and challenging yet fair. The atmosphere and music of the game does come off as a bit generic, but it's not without its charm. The gameplay can be a little buggy but it's fairly easy to avoid. Overall, it's a good (albeit somewhat unimaginative) game with enough fun to be had to make its current sale price of $0.99 USD (usually $1.99 USD?) worth the investment. The publisher, Chillingo, also publishes another Elasto Mania clone called Bike Or Die 2 ($6.99 USD). There are "lite" (demo) versions of both, so you can try both.
