Shadow Edge Tube
The all new Shadow Edge Tube hides the Bosch Battery Pack completely inside the down tube and provides therefore a nice shape and look of the frame, nevertheless the battery can be removed out of the down tube. This intelligent and innovative lid-mechanism is developed by corratec and patent pending. The lid of the battery housing is made of High-Grade-Polyamid with Glass Fiber Reinforcement and therefore its super strong and robust. The integration of the battery prevents the whole electronics in case of dirt and other external influences. The edge of the Shadow Tube is shaped very nicely and provides a sportive look. The special design of the edge improves the stiffness of the frame and causes more stability and security of the E-Bike frame.

BOOST-Standard
The BOOST standard offers new constructive freedom, but only for 29 ' and 650B Plus wheels.
The rear wheel hub grows in its width from 142 to 148 mm. There is an increase of 100 to 110 mm in the front wheel hub. Therefore, in the frame with the BOOST standard, 27.5 rear wheels with plus tires can be fitted in addition to the usual 29er wheels.
The crank also pushes 3mm outwards, which provides additional stability in the area of the bottom bracket and the larger chain length generally provides more space.
This additional space, in the otherwise constantly cramped bottom bracket area, can be used to increase tire-freeness or create a stiffer rear body by using larger bearings.
Wider rear and front hub.
Stiffer wheels and more space in the bottom bracket area.
Larger tire-free for Plus bikes.
