The exercise bike, dubbed HR Bank, was designed to provide urban dwellers with a reliable source of clean energy, but, perhaps more importantly, also for those in need of power during emergencies like natural disasters or wars.

“Our idea was that a person who bought an HR bank could not only use it as an external battery, charged from the sun or the grid, but in the absence of an external power source, could generate energy by pedalling,” said CEO Jonas Navickas.

A lot of thought has gone into this design with it not only being portable, but also storing a very useful 2kWh of power. Pedalling is not its only source of energy as it can also charge from the grid, car batteries, solar or wind power.

It is not only a clean source of power, but pedalling daily on it will help keep its owner fitter and healthier too.

The downside probably is the price of around €3,000 but I suppose you have to factor in it is a very useful battery storage, an exercise bike, and an emergency generator all rolled into one (saving some space too).
