C14 SP (seat post version)

In some cases, for example if your seat clamp is positioned very low, it may make sense to install the C14 directly on the seat post itself. We developed the C14 SP for this purpose. The two-part holder clamp of the C14 SP allows for quick and easy installation without having to dismantle the seat post.


The C14 SP taillight for e-bikes as a seatpost version.

Optionally with brake light function. Due to the G-sensor, the C14 detects braking and lights up brighter for a short time.

The 45 lumens rear light is made of black anodised CNC-machined aluminium, the optics of robust polycarbonate.
The C14 SP is waterproof and impact resistant according to IP68 and IK09. Due to the latest COB technology and
powerful Fresnel lenses, the C14 SP achieves all-round high visibility while reducing glare. The special arrangement
of the 14 LEDs and a sophisticated lens system also create a particularly homogeneous light characteristic.
The C14 SP is connected directly to the motor of the e-bike and is compatible with all current e-MTBs. An adapter
cable is required for installation on Bosch, Brose and Yamaha motors. This has a length of 13 cm. The C14 SP is
StVZO-approved and has a mounting width of 50mm.
The delivery includes inlays to increase the circumference from 31.6 to 30.9 mm. The two-piece clamp of the C14 SP
allows for quick and easy installation without having to dismantle the seat post.

Extra:Cable guide for light cables
