What is a prototype?

A prototype is a preliminary model of something. Projects that offer physical products need to show backers documentation of a working prototype. This gallery features photos, videos, and other visual documentation that will give backers a sense of what’s been accomplished so far and what’s left to do. Though the development process can vary for each project, these are the stages we typically see:

Proof of Concept

Explorations that test ideas and functionality.

Functional Prototype

Demonstrates the functionality of the final product, but looks different.

Appearance Prototype

Looks like the final product, but is not functional.

Design Prototype

Appearance and function match the final product, but is made with different manufacturing methods.

Production Prototype

Appearance, function, and manufacturing methods match the final product.

Svolta is the first backpack that doubles as a high-performance handlebar bag that can fit any bike.

Svolta is a trendy backpack that transforms into a bike handlebar bag quickly and securely, with limited fuss - in seconds!


Roll-top for adjustable volume and easy access

The rolltop can be easily adjusted depending on the content of your bag. The materials and assembly techniques provide 100% waterproof protection.

The front pocket is always accessible, featuring a water-resistant zipper

The front pocket is designed to be easily accessible while riding, perfect for carrying your smartphone or small items.

Key loop and quick access pocket

The front pocket is always accessible providing a main compartment with a water-resistant zipper and two easy access pockets with key loop, to get what you need on the go.

Water-resistant Top Lid closure + harness conversion, ready to ride!


During handlebar bag mode, the top semi-rigid lid, together with the internal compression bands + fabric flaps, provide enough protection from rain and moisture.

In case the perfect storm is hitting you on a ride, you can still close the bag with the rolltop + the top semi-rigid lid, ensuring full waterproof grade.

Safe access with one hand while riding

Stretchable bottle pocket + bungee loop 

Hydration and extra space on the outside of the bag are achieved by the  stretchable pockets, available on both sides, we opted for a special stretchable Lycra that ensures great durability and smooth look. The bungee loop has a double function that will allow you to carry an extra tall bottle or attach your favorite yoga mat to it!

Adjustable chest strap (detachable)

The chest strap provides extra ergonomics and comfort, including a double effect adjustability and the limite stretch system to let you breathe fully while riding. The strap is designed to be detachable for anyone who likes a more minimalistic approach. 

Shock Proof

 The bottom of the bag has a structure with foam and PE plastic foil to provide extra protection for your belongings.

360° Reflective design for improved safety

 All the graphic inserts and details are made with high reflective materials to enhance safety while riding into the dark.

As a handlebar bag it can carry 4L and as a backpack up to 18L. When it comes to the material, Svolta is completely waterproof and made of RipStop Nylon fabric PU coated (eco-friendly and extremely durable). It is designed to last long and resist any wear off.

 Available Colors: we picked two styles, SAGE grey and Stealth black, we recommend you to get both, in case you don't pick the one that represents your riding spirit the best... 

To create great products with stunning design, the selection of perfect materials is crucial. So that we can provide the best performance and durability.

We source our material from trusted partners. All the materials selected are then tested before the sampling process, to ensure they are fulfilling the specifications required for the design.

Sentier is offering multiple innovative products to their customers globally, now you have a chance to get a great discount on these products by adding them to your Svolta order, follow the instructions below.

 Svolta required 2 years of development, first to finalize the set of features and ensure a perfect market fit, then to develop a stunning design that worked smoothly in any scenario. We need your help to collect the funds needed for the first production batch and make SVOLTA the most innovative backpack, available to all the bike lovers around the world! 

The product development started 2 years ago, when Andrea the founder of Sentier Gear came across a challenge on his trip from Innsbruck across the Alps, to the top of Ultentall on his road bike. ( 3500m+ gain and +190Km ) He wanted a bag that could dynamically adjust volume and functionality depending his needs while riding without compromising the comfort and safety in any scenario. There at around 2000m on Giovo Pass (Jaufen Pass) the initial idea of a bag that could work as both backpack and compact handlebar bag struck him. This was followed by a lot of research, technology, and testing required to perfect the final product. 

Most of our designs were born on a bike, but it's quite important to fix the ideas on paper and start to develop features list and tech sheets before starting the prototyping phase.

 To create innovative products, you have to get your hands on material and technologies, that’s why we develop every detail and create all our samples in our workshop. This is the prelude to the TESTING phase, of course on our bikes, we are lucky to be able to enjoy our rides while testing some new samples!

 We love to hear your opinion and appreaciate if you like to share the SVOLTA BAG project on social media and with your inner circle of friends! 


Thank you to all the backers for supporting this project and to Kickstarter again for existing and sharing this amazing platform to make products a reality.

A special thanks to all the people that supported Andrea and Sentier in this ambitious project, as Andrea said "This is the first time I feel to have designed a product for my people, so thank you all for the inspiration!"

Risks and challenges

Since the launch of our first Kickstarter, the Bike Trolley, our team has been working night and day to dial in the design, production, and logistics to create the most innovative and performing Bike Trailer for you. We have learned a lot from our first Kickstarter and are confident we can deliver again the most innovative and performing product you'll love.

Over the past year, we've collected feedback from thousands of customers and bike lovers worldwide. Our team started developing SVOLTA over one year ago, based on the needs of our most influent and active customers, and finally, we are ready to present you the most innovative backpack that transforms to a handlebar bag for any bike.

We understand and acknowledge that no project comes without risk and challenges. Despite our planning, there are circumstances that may be out of our control. If we are met with these events, we promise to communicate with full transparency to you, our backers, and work to resolve all issues in a timely manner.

What matter to us is to provide the best quality products in the shortest delivery time, without compromising technology and materials.
