RIVA Basement purple

Lightweight, with contemporary geometry and a short wheelbase, BASEMENT is the best option for those looking for a fast and agile bike. The flip-flop hub allows you to quickly switch from Single Speed to Fixed Gear. BASEMENT marries high-quality materials and components to premium frame engineering.

4130 Cr-Mo
RIVA's frames prioritise comfort, design and technology, which is why they’re produced from 4130 Chromoly, an alloy steel also used in the aeronautical and motor racing industries.

This material is perfect for manufacturing light and durable bike frames, with thinner tubing that doesn’t require reinforcements at the critical joints. This means a super-comfortable ride thanks to its low rigidity. Cromoly’s mechanical resistance is 80% higher than that of aeronautical aluminium, the latter being more rigid, less comfortable and more prone to failure.

Raising the bar
When it comes to choosing handlebars, you normally have three options: comfortable riser bars, racy drop bars or the more-versatile ’.

But why settle for just one type of handlebar, one experience?

To make life easier, RIVA has supplied BASEMENT with all three different types of handlebars. Now you can truly explore every possibility with your bike.

Single Speed or Fixed Gear
BASEMENT has a flip-flop hub for switching quickly and conveniently between fixed gear and single speed operation. 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.

No matter which you choose, Fixed Gear or Single Speed, the standard front and rear brakes will stop the bike when you need to.
