POLKA BIKES DIABLO

When we were looking for inspiration for designing a new bicycle, we could not resist the temptation and went down to the depths of hell. As a result we have blended the bloody red frame with arcane black components and finished the new masterpiece with demonic drop handlebars, resembling the devil itself. Let us introduce Diablo - the bicycle dedicated to those, who agree that the forbidden fruit is the sweetest one...

So far we have ridden the advanced machines, whose capabilities we have not been using, on the roads for which they have not been adapted. We have wasted our time to adjust and repair the mechanisms that we do not need, in bicycles which we do not like. Technical progress has equipped us with dozens of complicated instruments. In concept, they are intended to make our life easier, however in practice what is happening is the opposite.

It’s about time to turn things around – we introduce Polka for Everybody!

Our bikes all come with a flip-flop hub, which means they have a freewheel cog on one side of the rear wheel and a fixed cog on the opposite side. This means you get to choose whether you want to run free or fixed, and you also have the freedom to switch back and forth between fixed and freewheel anytime.

Let’s start with freewheel. Freewheel is what most riders are familiar with. If you pedal forward, you will move the bike forward. If you stop pedaling, the pedals will simply stop and you will coast, and if you pedal backwards…well, nothing much is going to happen.

Fixed gear, on the other hand, is slightly different. Fixed gear means that the motion of the pedals is directly connected to the motion of the rear wheel. If you pedal forward, the bike will move forward. If you stop actively pedaling, but the rear wheel is still turning, the pedals will continue to turn. This means there is no coasting, if that back wheel is spinning, so are the pedals. And if you apply reverse pressure to the pedals, you can slow the rear wheel, or move the bike backwards if starting from a stop.
