Be consumers’ and brands’ most trusted partner for bikes and outdoors.

Values in Action

1 — Make Fans. Not Customers
Think differently. It’s a radical force that will lead us down new paths. We’re all in the relationship business. Our job is to build an emotional connection to our brand, products and services. Feeling empathy isn’t just about being nice, it’s about listening and truly understanding. Excellent customer service is an attitude, not a department.


2 — Make Today Count
Every day is race day. No time for guessing – leaders anticipate. Simplify, because nobody likes complicated. It’s free speed. Constantly monitor, improve, and adapt. Become even better tomorrow. We challenge ourselves and others to constantly raise the bar.


3 — Better Together
We are one team – within and across departments and geographies. Everyone puts forward their best effort. We depend on each other, are reliable and committed to meeting deadlines. Together we all create the environment we want to work in. We respect each other in our differences. Always listen to others’ ideas and build on them.


4 — Focus on Impact
To create an impact, we focus on things that really make a difference. We prioritise to achieve our goals faster. To get things done, we take ownership and help get projects over the finish line.

5 — Fail Fast. Fail Forward
We take calculated risks to innovate and move forward. If we fail, we learn from our errors and take immediate action. We admit and share missteps, because failure is part of the process and will only make us better.


6 — Data is King, Heart Rules
If you want to pitch an idea, things to change or simply add value, get prepared and make a case. Influence and inspire others by gathering facts and figures to back up your plans. We run via ideas not hierarchy – talent beats status.


7 —Think Big. Start Small, Move Fast
We are built on efficiency. We make effective decisions fast and consciously. You are safe to take action, having 80% of all information, until proven otherwise. Remember, our choices always affect others: our colleagues, suppliers and, most importantly, our customers. They are never in the room when decisions are made internally.


8 — You Matter
Everybody makes a difference to our team. We all give our best to accomplish our mission. We encourage each other to stay active, healthy and to live well. We also believe in the positive impact bikes and outdoor activities have on our lives. Let’s make our time together matter: at work, on rides and outdoors. This is just the beginning!
