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.
With long adventures on the road, a custom titanium bike with bespoke geometry makes every ride special.
From a weekend long ride to crit race the luxury of titanium is un-beatable.
On gravel roads nothing feels as incredible as a custom titanium bike with bespoke geometry.
Each tube, angle and mounting is specifically designed for the rider's ideal application
Mountain and Adventure
On the mountain or ultra distance adventures the details of the design cannot be overstated. Bespoke geometry ensures that the handling can be tuned to perfection for every rider.
