For people with taste

We go to great lengths to continually improve our lights, and this front light is a good example. The second generation of the waterproof V521s is more than 15 % brighter than its exceptional forerunner. The Terraflux 3 lens and a new high performance LED make this possible! An integrated soft start and an overload protection preserve the LED and make sure the light is compatible with most E-Bike light ports between 5 V and 12 V. The V521s has the latest technology, whilst the timeless design of the housing remains the same. 

Bosch HBM

The specially developed bracket for Bosch displays offers a clean installation option for our e-bike lights. For this newly developed part, Supernova introduces its proprietary Pure Carbon Composite (PCC) material. PCC is produced in ultra-high density and carbon reinforced, which makes it stiffer than aluminum while saving 50% of the weight. The material is absolutely resistant to UV radiation and to aging. It has excellent heat transfer properties.

Daytime running light

Many accidents happen because cyclists are being overlooked during daytime. A strong daytime running light can prevent this, so we recommend riding with lights on at all times. Our energy efficient V521s make this very easy. With their integrated daytime running light they improve your visibility at any time of day.
