Group Bicycle Tours: Explore at Your Own Pace
For a unique group experience in Copenhagen, consider a bicycle tour. It’s a flexible way for you to see the city, choosing your own route and pace. We can help you customize a special day that suits your group’s preferences. There are many activities to consider.
Bike Options
Choose from our strong city bikes, with either footbrake (脚刹车) or handbrake and 3 gears (挡). Footbrake bikes are suitable for urban groups. Fixed-gear bikes are commonly used by those staying in the flow of traffic, while handbrake bikes with gears or e-bikes are ideal for those less experienced or cycling outside the city.
Guided Tours
Our experienced guides, fluent in multiple languages, can lead your group. They are knowledgeable about all aspects of Copenhagen and can share impressive facts about the city’s past and present. Each guide can accommodate up to 10 cyclists.
Pricing Details
The cost depends on the bike type, rental duration, and whether you require a guide. Here are the rates:

All prices include two locks per bike. A 10% discount on all services applies to groups of 10 or more.

Soon after I took my steps into a research lab as a first-year college student, things went wrong. I left all the enzymes (酶) at room temperature overnight, instead of putting them in the freezer. This could have stopped me from performing experiments on my own, but my mentor (导师) Sauria, who was a postdoc, didn’t show anger or disappointment after I ruined all the newly ordered substances.
I went on to work with Sauria for more years and he set me up for success in science. From the start, Sauria showed a level of trust in my experimental skills that I did not always think I deserved. Even when I used 10,000 times more of an expensive reagent (试剂) than I should have, Sauria didn’t roll his eyes. Instead, he guided me through how the reagent works, making it a teachable moment. He also told me stories of his own mistakes, helping me gain lessons from the situation and do better.
After a few months in the lab, Sauria and I started a project together that required us to write a computer program. That was something I had experience in, and it felt great to teach him. Over the years, he’s always been open to a two-way exchange of information, which has led us to develop many successful projects. We even published a paper together — just the two of us. With these results, my confidence increased gradually during the process.
Looking back, I’m thankful to meet the mentor who drilled into me a desire to learn and gave me freedom to contribute my own ideas. I hope all mentors have their own inner excitement about new knowledge and skills and pass it on to others, because undergraduate researchers aren’t just an extra pair of hands in the lab — we’re also future scientists who need direction and encouragement.

Parks and walkways serve as vital sites connecting communities and providing spaces for relaxation, exercise, and social interaction. However, as the sun sets, these spaces can become less inviting and even treacherous. Effective lighting then plays a role in parks and walkways, which not only enhances their visual appeal but reduces the risk of accidents and criminal activity, reassuring people after dark.
Traditional street lighting systems often pose challenges. Conventional systems typically operate on fixed schedules or photocell sensors, resulting in unnecessary electricity usage during daylight hours or when there’s enough light. Moreover, repair teams may struggle with identifying faulty lights or addressing outages quickly, leading to periods of insufficient illumination (照明). Additionally, poorly designed or outdated fixtures can contribute to light pollution, negatively impacting human health.
The development of street light control systems has addressed many of the shortcomings of traditional setups. Smart lighting technologies, equipped with sensors and communication capabilities, enable dynamic control of illumination based on real-time conditions. The integration of the Internet of Things (IoT) technology and data analytics has reformed modern street light control.
Modern street light control systems have great flexibility, with lighting preferences designed to suit preferences of different parks and walkways. For instance, softer illumination may be preferred in garden settings, while brighter lights may be necessary in high-traffic areas or during special events. Additionally, color temperature tuning allows for adjustments in the warmth or coolness of light, creating different atmospheres and enhancing visibility. The initiative also reduces costs and demonstrates a commitment to the environment.
Apart from authorities, urban planners and lighting designers, successful use of street light control systems relies on more people. Involving local residents and park users in the planning process brings a sense of ownership and ensures lighting solutions that satisfy community needs and preferences. Public feedback mechanisms can also cast some light on visual preferences and usage patterns of the lighting systems.

Bering Sea snow crabs (蟹) are well suited for Arctic (北极的) conditions. But the southeastern Bering Sea is changing to more subarctic conditions through a process called borealization (北方化), according to a report released by the National Oceanic and Atmospheric Administration. It’s a process that’s also happening in ecosystems on land in Alaska. As a result, cold-water species like snow crabs move away or struggle to survive, while species typically found in warmer regions may spread into borealized areas.
“Like an Arctic ecosystem on land around Kotzebue is traditionally tundra and frozen, you don’t have plants. But as you borealize, you get more plants, even trees. So you can imagine what a huge transformation it is to go from treeless areas to forests. And it’s the same type of thing going from ice-associated to ice-free all year,” Mike Litozov, the lead author of the report, said.
This borealization, brought on by human-caused climate change, has more negative effects on snow crabs in the southeastern Bering Sea. That includes shifts in food availability for snow crabs, which means the species may face starvation, and an increased incidence of bitter crab disease. These were all evident in 2018–2019 when the special barrier — a cold pool of water in the Bering Sea — disappeared, bringing on extreme ecosystem changes that allowed different species of groundfish to move further north. Litozov and his team had previously confirmed that a combination of these factors caused the crash of snow crab populations between the years 2018 and 2019, when the species decreased by more than 90%. The population still hasn’t recovered.
After the last two back-to-back years without a commercial fishery, fishermen have also not fully recovered. The new report indicates the fishery may be entirely displaced in the coming decades. “The recent changes are not part of a one-off event and ecosystem-wide changes are expected to continue to affect snow crab populations in the future,” Litozov said.

Think back to when you were a kid. Movement was natural and brought you pure joy. Whether it was racing to the door or jumping on the playground, those moments were filled with excitement. However, as people grow up, the joy of movement gradually disappears.
Heading out into nature is recommended. McGonigal stated that moving outdoors in nature tends to put the brain in a state of heightened awareness of the present moment, which makes you feel energy and a connection to life. You can feel relief from stress and worry.
In addition, you should try joining a group. “These days, who couldn’t use another friend or source of support?” McGonigal said. “Make movement social.
You’ll exercise better by taking an attitude of gratitude. While you’re moving, find ways to appreciate your body, as opposed to monitoring it.
| A.Recalling happy moments proves useful |
| B.Exercise routines become an unpleasant task |
| C.The joy of movement can transform daily life |
| D.McGonigal suggests adopting a mindset shift |
| E.The movement you truly enjoy makes things easier |
| F.This puts you in a condition that’s relaxed and peaceful |
| G.Friendships and communities are formed through such movement |
