1.Reflex Knee Guards: Great protection for frontal impacts to the knee cup and upper shin. Polypropylene construction.
Bionics: Excellent protection as it encapsulates the whole knee joint and is constructed from more stiffer thermoplastic shell. The chassis also incorporates an aluminium insert on the front end of the knee for added rigidity. Upper shin is also well protected.
*Polypropylene is more flexible while thermoplastic of the quality levels on the Bionic is a lot more rigid.
2.Reflex: Can be worn under most jeans/trousers easily.
Bionics: Unless you wear baggy cargos/trousers with lots of room it's next to impossible to fit the bionics under regular jeans/trousers.
* This means that the Reflex guards are a lot more practical for day to day use or a ride to the office as well.
3.Reflex: Fulfills the need of regular bikers that do the usual weekend tours/city commutes.
Bionics: Does all that the Reflex does and also very good for stunters and motocross racers.
*For complete leg protection both types need to be worn with full length riding boots.
4.Reflex: Does not result in tank scratches/scuffs.
Bionics: Get ready to place protective decals on the sides of the gas tank or come up with innovative solutions. For eg. I intend to put small strips of dual sided industrial strength tapes on the inner sides of the guard and stick a medium thick sponge on the same.
5.User friendliness: Reflex: Havent' used them personally so cannot comment.
Bionics: Tend to loosen over the course of a ride. I don't know if this is due to my thin legs but would like to mention that I always find myself pulling them closer to the knee every now and then during long rides.
*Reflex users please comment on the same.
6. Bionics are shaped so as to flow with the entire knee joint which is why it is basically a two-piece chassis that bends when you bend your knees. (Leads to a fairly audible clasping sound between the 2 pieces when you walk. I find it cool. Some find it annoying)
Reflex does not flow with the knee joint.
Hope this clears your doubts.
Lastly: I'm selling my Bionics. Wanna buy?
