Ruby Gradient Di2
Our city bikes are real chameleons of the urban jungle. Based on this frame, you can build a comfortable city bike that will get you to work quickly and safely, a reliable gravel bike with belt drive and a geared hub, or a minimalist single speed bike. Maybe you are interested in
a different configuration? Choose for yourself!
Remember! At Loca Bikes, our bikes are always made to order. If you would like to change the paintwork or have any special requests concerning the configuration, let us know!
- The geometry, inspired by the gravel bikes, will allow you to cross junctions comfortably, as well as riding off into the unknown on gravel paths
- Our city frames are made by hand in Poland. They go through extensive tests in the factories and have already survived many thousands of kilometres covered in European cities and on cycling tours. The entire design, construction and painting of the frames are also local processes
- Frame made of 7020 aluminium, which is stronger, lighter and has better damping properties than the popular 6061T6 alloy
- Clearance for a max of 700x45c tires
- Front 100x12 mm thru axle
- Full carbon fork and tapered headtube
- Choose from 11-speed, 8-speed or 1-speed (single speed) drivetrain - pick the one that suits you best!
- Hydraulic disc brakes provide excellent stopping power in all conditions
- Possibility to mount full-length fenders, rear rack, and two bottle cages
- On request, we can fit tubeless tires
This bike has been created for an individual order. If you like this direction, we would be happy to create a similar design for you. For this reason, complicated painting is not included in the price - we will quote it for you individually.
The technical details of individual parts and information on frame geometry can be found below.
The price is for a bike matching the specification below. The configuration shown in photos may be different

Geometry
The geometry of Loca Bikes city frames closely resembles our gravels. The wider wheelbase and modified rear triangle allow the fitting of belt drive and gear hub, making our city bikes highly versatile and allowing you to move around the city efficiently in all weather conditions. The balance between stability and responsive handling, will allow you to take the bike to less traveled paths and use it as a gravel bike.
