Description

DK 180347 B1 1 Transport System Field of invention The present invention relates to a transport system comprising a bag that is configured to be attached to a bicycle and to a method for attaching a bag to a bicycle. Prior art There is an increasing awareness towards transportation by using bicycles. Economic instability and ever-increasing climate change are just two of the many reasons riding a bike is a good alternative to driving a car or a bus. Many cities around the world are trying to promote the use of bicycles in an attempt to reduce traffic congestion and improve air quality, as they are considered by most traffic experts to be a key to urban mobility. Transportation by means of a bicycle is associated with a lot of advantages. It is much easier to finance a new bicycle than a new car.

Bicycles have a low manufacturing footprint when compared to cars. All manufactured goods have environmental impact, but bicycles can be produced for a fraction of the materials, energy and shipping costs of a car. Furthermore, bicycles produce no pollution when in operation and they also eliminate the oil, fuel and hydraulic fluids dripped by automobiles onto the road. In addition, bicycles save taxpayers money by reducing road wear. Using a bike for transportation is an effective way for losing weight and improve the overall health for the person riding the bicycle. Furthermore, in many cities bicycling is faster and more efficient than taking a car.

One of the challenges when riding a bicycle is storage room for personal stuff (laptop computers, tablets, sports equipment and the like). Even though there has been developed a variety of rucksacks for cycling, it is

DK 180347 B1 2 a major disadvantage that riding a bicycle with a rucksack will cause a sweaty back and leave the rider with a wrinkled jacket or shirt. Accordingly, it is rear to see business people riding a bicycle with a rucksack prior to a meeting.

Therefore, prior art bags are typically attached to a rear rack of the bicycle. This introduces an instability for the rider due to the high vertical position of the bag. Moreover, this option is not possible for bicycles that are not equipped with a rear rack.

Equipment (e.g. a handlebar basket) mounted on the handlebars of a bicycle is used for small items such as shoes, small plastic bags with groceries. However, these type of equipment is not well-suited for carrying a large and/or heavy bag (more than 10 kg, preferably at least 12 kg such as 15 kg or 20 kg). Accordingly, is would be desirable to have a transport system that can be used when riding a bicycle that is not equipped with a rear rack. WO 2011/116758 A2 discloses a holding device for attaching containers to a carrier, in particular for attaching panniers or similar containers to a luggage carrier. The holding device comprises a rod, rail, strut or plate. The holding device comprises variable attachment points for the attachment of elements for fastening the holding device to the carrier. The holding device, however, is not or user-friendly. Therefore, it is desirable to have an alternative that is easier to use. It is an object of the present invention to provide a transport system that can be used when riding a bicycle that is not equipped with a rear rack. It is also an object of the present invention to provide a transport

DK 180347 B1 3 system that is more stable than the prior art transport systems and that allows for save transport of large and/or heavy bags.
