Focused Attention to
​Quality and Safety

The bicycle is an invention of immense practicality across the world. Kasai imagines making it even more useful by adding the simple technology of lighting. This is a new idea the 21st century, but can we feel it can be improved upon in ways. We look at sourcing quality materials  and keep tight control over build quality.

• With our innovative design, our dynamo hub exhibit almost the lowest drag in the industry, not that drag should be a deterrence to having reliable and sustainable lighting. One German test claims a cyclist only loses 3 to 5 minutes over a 100km ride. 
• We continually get feedback from long distance cyclotourists to help improve our products
• We source high-quality Japanese copper wire.
• We test for corrosion resistance in multiple environments.​

NEW FOR 2020: We are excited to introduce a new development in Dynamo Hubs....a "Field Serviceable" design that you don't have to ship back to the factory to repair
