INTERNAL CABLE ROUTING

Internal Cable Routing inside the frame for protection and a stylish design.

IET - Integrated Engine Technology

Constant improvement and desire for better design lead to an engine bracket forged out of high grade aluminium.

• Improved stability and stiffness by forged high grade aluminium
• Save connection between frame and engine
• Service- and maintenance friendly engine and battery position
• Protection from external forces
• Design-orientied Bosch integration concept
• Compatible with all Bosch drive units

BK30 Optionales ICR (Internal Cable Routing)

Optional ICR (Internal Cable Routing) offers
significant benefits by routing all cables
internally through the frame or cockpit, resulting
in a clean, tidy, and aerodynamic appearance.
You can choose to route the cables
either through the headset, ensuring a
sleek look, or through openings in the down
tube, which facilitates maintenance. Note
that most of our bikes come standard with
ICR through the head tube.

BK30 T47A Bottom Bracket

The T47A Bottom Bracket combines the
best of the T47 and BB standards. With an
asymmetrical configuration – T47 external
bearing cup on the drive side and T47 internal
cup on the non-drive side – it offers flexibility
for various crank spindles such as 30
mm, 29 mm DUB, 22/24 mm GXP, and 24
mm Shimano.

650B Wheel Size

650B wheel Size is the new MTB standard. The 650B wheel is not a compromise between 26“ and 29“. It combines the advantages of 26-inch models (weight, torsional stiffness and agility) with the advantages of the 29“ impeller (increased smoothness, rollover behavior, increased cornering stability).

29" Wheel Size

Large wheels roll better. 29 inches require about eight percent less energy than the 26-inch version. The 29“ wheel takes longer to get going, but rolls easily and quickly over rocks and roots, which brings an additional advantage – more comfort.

Larger wheels roll over obstacles more easily. The ability of a wheel to roll over obstacles is proportional to its size. A 29" wheel, which is about 10% larger than a 26" wheel, can roll over 10% larger obstacles. The larger diameter wheels have more angular momentum so they lose less speed to obstacles and rough sections.

29" bikes tend to offer taller riders a more "natural" frame geometry.  

26" WHEEL SIZE

26“ wheel size is suitable for shorter people who are looking for a very versatile bike.

28" WHEEL SIZE

28-inch roll easier than the 26-inch version. The 28“ wheel takes longer to get going, but rolls easily and quickly over rocks and roots, which still brings an additional advantage – more comfort.

DI2 Ready

The frame is by default already prepared for the electronic gear shifting of Shimano, in case you want to update to this new type of gear shifting at a later point.

Dropper Seatpost

Dropper Seatpost with control lever on the handlebar or seatpost.

THROUGH AXLE

Through-axles have the advantage that they are larger in diameter than conventional 9 mm axles and thus are significantly stiffer.

180 kg system weight

The bike exhibits the worldwide most stable and safest corratec e-bike frame and can carry up to a total of 180 kg system weight.

BK30 Boost-Standard

The Boost standard enhances the stiffness
and stability of bicycle wheels
through wider hub flanges and steeper
spoke angles. This results in more effective
and precise bike handling. The wider
rear end allows for even shorter chainstays,
further increasing agility. The bearing
points can be made wider and therefore
stiffer, improving the frame‘s robustness.
Additionally, the wider rear hub enables a
greater variety of chainrings and increases
clearance at both the fork and rear
end, which is particularly beneficial when
using wider tyres.
