Why CALCULUS
We're a small company based in Hermanus, South Africa who loves the journey of creating bespoke bicycles.
We know each person is different, each body has unique bio-mechanics and no-one rides in the same manner.
At Calculus Bikes we believe every rider should have a perfect ride.
We engineer each bike according to our clients' exact needs and ensure that the finished product is the best possible version of their dream bike.
