2014 Bosch Active Line and Performance Systems
Bosch's new 2014 drive system is already grabbing the headlines with the design awarded a Red Hot Design Award. There are two main versions of the system: Active Line and Performance Line. The former is found on most bikes while the later is found mainly on bikes prices at £2500 and above. The Performance line is more sporty with assistance up to 275% (up to 60nm torque) provided while the Active Line provides up to 225% assistance (up to 48nm torque) and as a result a longer battery range making it ideal for touring.
One of the key differences from the 2013 system (now referred to as Classic) is the smaller sprocket size. This works as the gearing is inside out with one pedal revolution equalling two and a half turns of the small sprocket. The advantage of this is that it is more difficult for the chain to come off and also gives a higher ground clearence.
Another key difference is the number of readings the three sensors take (speed, cadenance and torque) which is now 1000 readings per second compared to 200 per second on the Classic system.
The batteries options remain the same (300wh and 400wh) however they now slot into position much easier particularly in the case of frame mounted batteries. They also support charging directly on the bike. The remaining differences are largely cosmetic e.g. slightly larger Intuvia Display and new motor design.
