SevenRivers
3in1 bike bag

The 3in1 bike bag from SevenRivers made a very good impression in our test. As well as being easy to assemble, the product impresses with its simple, timeless design and wide range of colors. The material is made of waterproof, thermoplastic polyurethane and has a high-quality appearance. As a real multifunctional talent , the product can be used as a carrier bag, shoulder bag and bicycle bag. It offers plenty of storage space, a removable laptop compartment and a front pocket for smaller items. The reflective design elements ensure sufficient safety during transportation and in road traffic. The only thing that took some getting used to was attaching it to the luggage carrier.

Advantages

✅ Convertible into a backpack or shoulder bag
✅ Stylish

The first impression

Packaging and contents

ℹ️ Here we take a closer look at packaging. Sustainability is becoming an increasingly important factor. In addition, adequate protection of the product must of course also be guaranteed. Are the contents of the packaging complete and does the manufacturer make it as easy as possible for me to use the product straight away?

The 3in1 bike bag from SevenRivers is carefully packaged. The product is made of thermoplastic polyurethane. The correct handling and assembly was briefly described in German on a small card for the individual product components . A more detailed description would be desirable. Nevertheless, this is a very good way to send a product.

The pannier is ready for the practical test.

The pannier comes in a timeless design with the color option anthracite, further options are available in the colors grey, jeans blue, olive green and black. Particularly noteworthy is the increased safety in road traffic thanks to the reflectors integrated into the appearance. The workmanship of the bag is of high quality and is characterized by integrated edge protection . This robust finish ensures a long service life and makes the bag particularly hard-wearing. Another aspect worth mentioning is the material used. The pannier is made of 600d TPU material and is PVC-free. The dimensions of the bike bag are 57 x 30 x 15 cm and offer sufficient storage space for personal items.

This is what our practical test showed

We really enjoyed using the 3in1 bike bag from SevenRivers during the test. Assembly is child’s play and can be carried out by anyone. With this pannier, you are perfectly equipped for any situation and can enjoy all the freedom you need when cycling. The high-quality 600d TPU material not only looks good thanks to its fabric look. It is also 100% waterproof and can be easily cleaned with a sponge. Thanks to the individual adjustability of the Smart Connect system and the bike bag, it fits almost any luggage carrier (including e-bikes). Even on bumpy rides, the bag stays firmly attached to the carrier.
The spacious SevenRivers 3in1 bike bag offers 24 liters of space. It can easily fit a laptop, folders and shopping. The bag also has a front compartment and a bottle net. The high-quality materials, pleasant carrying comfort, good functionality and well thought-out safety convinced us in the practical test.

Price/performance ratio

and ratings from consumers

ℹ️ Finally, we examine how the product compares to the competition. Can it keep up with the competition in terms of price and quality? Would we generally recommend buying it? We also look at the consumer reviews and check whether the critical and positive reviews are actually justified.

CriterionRemarkScore achieved*
Price / performance ratioVery good performance in the mid-price segment80 points
Rating cut4.7 out of 5.0 on Amazon85 points

Weighting: 15%
*The maximum score is 100 points

On the Amazon platform, consumers rate the product with an average of 4.7 stars. One common criticism is that the claws for attaching to the bike rack do not open under the weight of the bike bag alone. You have to apply counter-pressure with your second hand. Many customers like the fact that the pannier offers enough space. In our practical test, we were able to confirm that there was enough space and that the assembly was unusual at first. It is easier if you use both hands.

Prices of up to € 179 are charged on the Internet for equivalent products. Very inexpensive products are available from as little as €55. The 3in1 bike bag from SevenRivers is therefore currently in the mid-price segment with a price of € 69.90. For the quality and performance received, the price-performanceratio isgood.
