It’s a small ball. Not one you’d throw or catch, though. It’s a bell-ringing ball. You wouldn’t normally associate balls with this application, but this one sure rings a bell – on the bike. All you need to do is attach the magnetic ball to the desired position. Nello, the removable bike bell, is easy to use and comes with an adaptor for non-magnetic bikes, plus three different tones. Nello’s always good for a surprise. Because every time you reattach the bell, the tone changes. So you can either choose your favourite one or let yourself be surprised every time. The ringing ball is available in four different colours.
