the cycle force looks like it has 2-piece cranks, with a little beefier profile. The Kent has one piece cranks that depending on how much you weigh, and how much off-roading you might do, may not be as resistant to bending. (though you'd probably have to be doing some drop-offs or jumps to bend the crankarms). The Kent does have a quick-release seatpost collar though. Might be handy, might not be.

Otherwise probably mot much difference between the two. Have fun riding!
