Try Rocky Mounts
Roughly the same price, and you don't have to use up a cleat.
I've been using one of their clutch fork mounts and some extra of the hardware they talk about to integrate it to the tiedown system (bought a wheel holder and use the Rocky Mount hardware to attach it to the bed so it won't move around) for over 2 years, and I can't complain at all.
EDIT: You want the Clutch SD towards the bottom. Also, if you call they will sell/send you some of the extra hardware. Also, their screws are torx, and that's better security because someone's unlikely to have one of those on hand to steal something.
One other quick question: if it is a beach cruiser, you may want to be sure that your front wheel(s) have quick release axles. Otherwise, it will be a pain using a mount that requires removing the front wheel.
