At Loca Bikes, we produce aluminium frames for our gravel bikes and our city bikes that come with internal gear hubs and a belt drive. The main advantages of our frames are high durability, low weight, well-thought geometry and fine details like hand-smoothed welds. The frames are designed and produced in Poland.
Our gravel, City Man and City Lady frames are made of 7020 aluminium tubes and weigh only between 1.6 - 1.88 kg depending on size.
Along with the low weight of the 7020 aluminium comes its high durability and stiffness which is proven by positive results of extensive stress tests carried out at the factory. Additionally, 7020 aluminium does not require heat treatment which allows for easier repair compared to the common 6061 T6 alloy.
Our gravel and city bike frame production is carried out in Gliwice, Poland where not only tubes are welded together, but also dropouts, bottom bracket shells and head tubes are produced. The frame’s design, painting and quality control are also part of a local process and that all takes place in Wrocław. The tubes come from German mills and have all necessary EN certificates.
In addition to weight and strength, geometry is also a crucial element of a bicycle frame. Our gravel bikes were designed in cooperation with Kamil who runs Kajak Custom - one of the most famous Polish framebuilders. Our gravel bike frames are characterized by a relatively short rear end and a fairly narrow wheel base, providing great maneuverability and excellent acceleration during sprints. At the same time, the short top tube and taller head tube (than on racing road bikes) allow you to take up a comfortable, more upright position, making it the perfect machine for long tours and bikepacking.
Our city bike frames for internal gear hubs and a belt drive have a larger wheel base and more relaxed angles compared to our gravel bikes. This has been done to ensure stability even in the chaos of city traffic. However, they will still surprise you with their nimbleness and acceleration, which are at a much higher level than the city bike with a longer wheelbase. The tapered head tube on both frames provides confident handling, while the carbon fork offers a good level of shock absorption and additional weight savings over aluminum or steel constructions.

Both our city and gravel bike frames are suitable for mounting disc brakes in the flat mount standard. Disc brakes provide much better braking power and modulation than rim brakes.
Stability and stiffness are positively influenced by the use of thru axles made by Polish manufacturer BB Components.
Both gravel frames and city bike frames can accommodate tires with maximum size of 700x43c. Additionally, on each frame you will find dedicated places for mounting full mudguards, a rear rack, and two bottle cages. City frames additionally allow mounting of a central kickstand.
Details make all the difference. That's why our frames have perfectly smoothened welds, the cables are routed inside the tubes for a minimalist look and easy bag mounting, and feature tensioning bolts in the rear dropouts which help keep the rear wheel aligned and the chain/belt properly tensioned on our city bikes.
City Man and City Lady frames are compatible with belt drive. The right dropout can be uncoupled, so if you want to change the drive type, you will not need to make any frame modifications.
Our LOCA city bike and gravel bike frames come with a 5 year warranty.
