Take one trishaw – a bit like a tricycle but with two wheels at the front – add two passengers and a volunteer driver, then get out in the fresh air for a pedal.
That's the essence of Cycling Without Age, a movement that started in Denmark 5 years ago and now has over 1,000 trishaws operating in 30 countries around the world.
Here in New Zealand, a large retirement village operator called Arvida is giving it a go, and there are plans to expand Cycling Without Age into the wider community, too.
Could cycling be the key to a happier and healthier old age?
This Way Up visits a retirement community in Rotorua to find out.
