Foi o melhor investimento que fiz. Uma bicicleta completa, com materiais de qualidade e acabamentos impecáveis!


Tenho vários tipos de bicicletas, mas nenhuma é tão bonita e boa quanto esta. Cada componente, cada detalhe parece ter sido cuidadosamente escolhido primando pela qualidade, funcionalidade e estética.

André Arigony Souto

A bike atende todas as expectativas. E faz grande sucesso em Porto Alegre. E o atentimento é impecável. Recomendo 100 % a compra.

Glaucia MX

Bike perfeita, sem defeitos e linda demais. Moro em um lugar onde partes do asfalto são péssimas pra se deslocar e andar com a Basement foi surpreendentemente confortável.

Rodrigo Hubner

Bike perfeita! Acabamento primoroso é o diferencial da RIVA, também como o atendimento. Muito satisfeito com a compra. Parabéns à todos envolvidos, RIVA.

Basement SP also brings an unprecedented innovation, it is the first bike with the saddle coated with Pinãtex, replacing the animal leather with a material produced from the fiber of pineapple leaves that has the same physical properties and strength of leather. An exclusive RIVACycles.

Produced in Italy and Spain out off fibers from Southeast Asia, the material is handcraftedly applied on our saddles by SRD Brazil so you get the best finish and gripping.

At Basement SP you can choose the handlebar of your choice: Drop, Riser, Bullhorn and Pursuit. And of course, we have the finishing of your choice, with ribbons or handles.

CR-MO 4130

BASEMENT's frameset is produced with a special steel alloy in chromium-molybdenum SAE 4130, also used in aeronautical applications and in the construction of vehicles for automotive competitions. The frames are built with double-butted tubes, of variable thickness, which allow the application of the right thickness in the right place, guaranteeing durability without adding unnecessary weight.

Welded through the TIG welding process, the frame has integrated chain tensioners with the dropout, making the transition from Single Speed to Fixed even easier.

Singlespeed or Fixed Gear?

BASEMENT comes with a flip-flop hub that offers a smooth transition between Fixed gear and Singlespeed.

The flip-flop type hub comes with two sprockets, one on each side of the hub, to give you the possibility of a "fixed pedal" (sprocket without freewheel) or with freewheel (conventional ratchet).

In fixed-gear mode, the sprocket has no freewheel, meaning when the pedals turn, your legs go with. If you want to feel really connected to the bike and the street, this is the way to do it.

If you prefer a more relaxed ride where you can coast down hills like on any other bike, simply flip the back wheel over and use the freewheel sprocket.
