    Help Me Find My Size

    The Payback bike seat security system locks down your seat post and saddle with Fortified security bolts. If either are ever stolen, we'll replace them with a brand new one. That's a Fortified promise. Basic Payback seat post security is only $15. Add $10 for a saddle bolt which enables your anti-theft guarantee. The key to the Payback is in its proprietary tool for unlocking. You can unlock and adjust your seat in a snap, but would-be-crooks are left scratching their heads.

    Payback accommodates all 5 of the major seat post sizes, and all modern saddle bolt sizes (if you have an old bike with a horizontal bolt, sorry!) So unless your post and saddle are super unique, you're covered!
