Calculus Bikes

Dream bikes for real riders

Calculus Bikes is the first South African Bike manufacturer building bamboo bikes. We decided to choose Bamboo as our frame building material of preference along with carbon fibre.

The ride characteristics of a bamboo frame are superior to aluminium or a full carbon frame due to its damping properties. The bamboo absorbs much more of the vibration from the road or mountain.

By using bamboo tubes and carbon fibre as lugs the best of both worlds are achieved: a light, stiff and responsive frame that absorbs the unwanted vibrations.

Custom Engineered Bikes

We know each person is different, each body has unique biometrics and no-one rides in the same manner. At Calculus Bikes, we engineer each bike exactly according to our clients needs to build them their best riding dream bike using Bamboo and Carbon fibre.


The design starts with and ErgoFiT measurement of our client. Measurements, advanced algorithms and years of experience gives us a perfect indication of the ideal position for the rider on his or her bike.

Once we have the rider’s position we design the frame around those parameters taking into account the type of riding the bike will be used for and the desired ride characteristics the rider wants.

The components are also chosen to best complement the design and desired riding characteristics. Whether you choose Shimano or SRAM drivetrain with carbon or aluminum wheels it is all done as part of the design.


With the totally customised design in-hand the build starts.

The building of the frame is done with a combination of techniques ranging from high-tech 3D printing to hand layups of carbon fiber between the bamboo tubes.

When the frame is completed the components are assembled to finish the whole bike before sending it to the lucky new owner.
