The Senza is an innovative system which is designed to render a bike totally secure. Two separate locks are used to accomplish this,both uniquely designed to fit the needs and desires of riders of all ages and experience levels. What makes the system truly innovative is that both locks are not only stored on the bike, but are in fact part of the bike itself! There are no additional parts that the rider has to lug around, Nothing to get tangled, nothing that you can forget or can be stolen, nothing to change the look of your bike. The Senza leaves the rider to do exactly what they were meant to do, just ride!
