COO HARO Bicycles



Engineering Design

In close co-operation with our customers and frame factories we turn your ideas into reality.

Together with our customers, we use 3D design models to take us from the initial concept through to the finished bicycle.



Logistic & Distribution

Our philosophy is to provide the right product at the right time in the right place. This applies to the finished bicycle and e-bike just as much as to the parts needed to build them.

With our global warehouse service, systematic monitoring of lead times and material requirements, and a highly refined logistics and distribution strategy, we can offer our customers reliability, flexibility and optimum delivery capacity. To achieve this, we use modern tools that ensure transparency, generate reports, and deliver rapid response times and the very best after-sales services.



Quality Control & Repair System

Quality is the key to success and is in our DNA! Therefore, we work every day to optimize our workflows. At Kenstone we work with a vendor evalution system to improve the collaboration with our suppliers.

We know that a good result starts right at the beginning. That’s why we inspect all incoming goods carefully before we start production.

As a special service for our clients we offer QC checking online.
