What it is:
As of July 10, 2017 Bosch is launching a new trail riding feature for Performance Line CX called eMTB mode. This new feature will automatically change between assistance modes depending on pedal pressure for optimal support on different types of terrain, allowing riders to concentrate their full attention on the trails.
The eMTB mode replaces the traditional Sport mode (210% boost) with a “Variable” mode which provides assistance between Tour (120%), Sport (210%) and Turbo (300%). This gives riders ideal power at all times, even at low pedaling frequencies, without them ever having to toggle between support levels. The amount of assistance is dependent on the rider’s pedal pressure (see above graphic), starting with light drive unit support at light pressure and increasing to maximum support as pedal pressure is increased. The system responds almost instantaneously and the rider continues to experience the “natural riding sensation,” whether starting off or accelerating. As soon as the pedal pressure decreases, the power assistance is smoothly regulated downwards. Thus the rider has much greater control when riding through narrow, winding sections of a trail.
How to Upgrade to eMTB Mode:
eMTB mode is compatible with all Performance Line CX Drive bikes. It requires a Bosch Software update, which is complementary for those who purchased their CX equipped bike through The New Wheel, or for a fee of $20 (subject to change). Please make an appointment here.
Update Not Revertible
Please note that the update is not revertible. Sport Mode will permanently be replaced by eMTB Mode on all CX Drive bikes that are updated with new software and standard on all newly manufactured CX Drive bikes.
