Could I use the Ogio Mach 5 bag for cycling? I commute to work by bicycle and had a recent incident that involved Supermanning over the bonnet of a car and landing on the tarmac. I'm a software developer and carry a high-end laptop with me which was damaged in the fall. A motorcyclist friend recommended the Ogio Mach 5 which is designed for motorcycle riders and has a hard shell. I'm thinking of using this for cycling. 

Has anyone here had experience of this bag? Do you think it would suit cycling? 
Otherwise, any other hardshell bags out there that would carry a 17.3 inch laptop and suitable for cycling? 

My thinking is that MTB riding position is similar to some motorbikers so it could work well.
Trying to stick to objective points. When choosing a backpack for cycling you need to consider a couple of things beyond normal backpack considerations.


Fit - can the straps keep it stable as you pedal or will it flap
around
Weight - does it add too much?
Back ventilation - will you back get too sweaty
Aerodynamics can also be a consideration - shape, flappy straps etc. 


Fit and aerodynamics are probably fine as this is meant for motorcycle use. You'll definitely want to check the weight. Back ventilation could be a problem as it obviously is meant to be worn over a heavy motorcycle jacket.
