Bike Lockers: Structure and Design

Bike lockers will appear in the upcoming years, mainly in every city of Europe. The trend of ecological and healthy transportation comes into our lives. People need to leave a bike or an e-scooter in the place where Locker will protect the transport from rain, thieves, and vandals. Few companies already produce the boxes, but most make mistakes and can’t take the market over. In this article, I gathered the main features of the bicycle locker structure and design. To make reading clear, I sorted the rules by topics.


Bicycle lockers can be anywhere: near Shopping malls, Offices, Schools, hotels, garages, museums, train and metro stations, public places, homes, garages, etc. It is possible to make different lockers for each location, but the locker price will be overwhelming. For this reason, companies try to make one universal model for any location. Some companies offer additional features, like the Bluetooth locker, a green roof, e-charging, or a different color. These changes are not crucially affecting the construction but help to reach the needs of the customers.

Safebikely, they have the best design for now.


Bicycle lockers should be compact. One rectangle must include two bicycle slots on two sides.

The bicycle should enter the locker starting from the rear wheels.

The basement may be made for each rectangle separately for the ease of transportation or changing the sizes if the amount of boxes does not satisfy the demand. However, you will get the double layer of the inner walls. So, the basement can be made for all of the planned sections.

The¬†walls between slots can be made out of¬†the¬†metallic grid or¬†with patterned or¬†transparent material. It is made for¬†safety reasons. The¬†outer walls can also be patterned or¬†transparent. It depends on¬†the¬†safety requirements from the¬†government or¬†a¬†company. But¬†the¬†box must not¬†lose the¬†primary purpose¬†‚Äď the¬†safety of¬†a¬†bike.

The lock on a box must be covered from the rain. The lock can become rusty soon, and the opening of the door will be a tragedy.
Handles must be comfortable and keep warm temperature. On hot or cold days, the metallic handle can reach an enormous temperature so that it will be uncomfortable or even risky to touch the handle. They can be either made of a material like wood or can be covered by a sunlight.

The locker must be easy to clean. There should not be details that make cleaning impossible, like too sharp angles or too small patterns.


If we want to place the boxes on the street, we should not make them too high; otherwise, boxes can damage the view of a city and can be banned to use in the city.

The size should be well suited for standard e-scooters (like Ninebot or Xiaomi), city bikes, road bikes, and MTBs. Let’s assume that the max size of Mtb can be XL (22 inches frame) with 29 inches wheels. Don’t count any unique bikes that are too high or too long, a bike with four wheels, or a bike with too wide handlebars.

For example, I took Cube Stereo Hybrid 160 with a frame length of 128,9 cm and 73,9cm (29 inches) wheels. That means that the length is 129+74=203cm + 2-5cm. The manufacturer of steel usually uses 2m and 2.5m width of a steel sheet. So we must satisfy 2m. In this case, we put the bicycle not straight but under angle.

The¬†height is equal to¬†half of¬†a¬†wheel 37cm + frame and¬†handlebar size 65cm + 7-10cm- + additional space 3-5cm, so it is 115 cm-120. don‚Äôt forget about the¬†height of¬†a¬†basement and¬†the¬†‚Äúfeet‚ÄĚ to¬†make the¬†construction stable.

The width is equal to the size of the handlebar. Mtb handlebar has a maximal of 61 cm. Don’t forget about the real part. The width of tires (excluding fatbikes) and the end of the frame are important. So, the width in the form should be 65-75 cm. The manufacturer uses a 1.5m, 2m, 2.5m sizes of the sheet, so we can use 75 cm for 2 walls, or 67 for 3 walls (but it’s hard to measure it right), or 62.5cm for 4 walls using 250cm sheet. Don’t forget about the angled laid bike.

we see that in this example the size of a box is too large and it could be lower if we assume that most of the people use normal-sized bikes, however, don’t forget that e-scooter must have enough space there too, maybe the scooter can be laid on a wall to save space


The purpose of the box is to protect the bicycle; the design and sustainability come next.
The material used should last long and should be easy to clean and produce. The material should be water, cold, and dirt resistant. However, the price of the material should not be extremely high unless it is corten steel.

Why can corten be a good idea? If we implement corten steel, we don’t need to care about cleaning it, and through times corten will look better. Corten seems nice with a green roof. However, this is an assumption. Probably due to its size, it will look unpleasant.

That is just a pot for the flowers, but it looks like the bicycle locker.


Color should be neutral. It is better to use one color. The color may differ due to different surroundings and company styles. If it is a specific material, like corten, we save the initial color.

The box lock

There can be three types of locks in the locker: no locks, key (password) lock, and Bluetooth (Wifi or cellular) lock. Each type has its scenario of usage:

  1. No locker can be used, e. g., in schools, shopping malls, or other locations, where lockers are not used for a direct profit. Instead, people can use their locks, then the purpose of the box is to keep safe the details of a bike: wheels, cranks, saddle, or forks. These parts are popular in the darknet.
  2. A Key or a password lock can be used near houses (e. g., in the courtyard), offices, etc. That means that only members of one community will be able to use the bicycle parking slots. The boxes can also be used for profit by renting out the slots for months or years.
  3. A Bluetooth (Wifi or cellular) lock can be used for mass usage. These boxes can be placed anywhere and are typically used for profit. The owner can be the shopping mall, business center, University, or even a government.

structural stability and safety

The¬†box must not¬†fall or¬†disassemble due to¬†external forces like vandalism, punching, or¬†obviously¬†‚Äď using a¬†screwdriver.
That means that only an authorized person can disassemble a box, e. g., with special instruments.

other examples

By this link, you may find different companies who produce or use bike lockers. I used their photos in this article.

Holy Bike, my project of a bike locker will use all of the rules mentioned above to make the most comfortable and well-looking Bike Box

COR-TEN¬ģ Steel

Ziedlejas welness resort

COR-TEN¬ģ steel became popular among architects. There are three reasons for¬†that:

  • Corten needs zero maintenance.
  • Corten changes colors and¬†becomes more beautiful year after year.
  • Corten is a¬†sustainable material

COR-TEN¬ģ was invented for¬†building coal carriages in¬†1930s America. Corten steel plate might look like it‚Äôs rusty. Still, thanks to¬†clever manipulation in¬†its processing, the¬†outer oxidization protects the¬†steel from further corrosion, as¬†well as¬†making it look excellent indeed. There‚Äôs no¬†need to¬†paint Corten, and¬†it changes the¬†color itself over time. Last century Corten was the¬†metal of¬†choice for¬†containers and¬†other shipping elements. More recently, though, it‚Äôs become the¬†material of¬†choice for¬†many artists, architects, and¬†interior designers. Corten steel cladding is popular and¬†often used for¬†buildings, giving it a¬†tough coating against the¬†elements and¬†an¬†industrial-looking edge.

How is it made

Weathering steel is an alloy, which is what makes it so resistant to the elements. The addition of nickel, copper, and chromium at the production stage means that a protective patina will develop on the surface of the metal over time.

Patina Formation Process

Under the influence of the wet and dry cycles, the rusting process of this steel initially proceeds in the same way as with ordinary metal. However, over time, the rust develops into a layer of patina, and its color changes from orange-brown to light or dark brown.
The¬†rate of¬†change and¬†the¬†final color depends on¬†the¬†ambient atmospheric conditions and¬†contaminants in¬†the¬†air¬†‚Äď sulfur will accelerate the¬†oxidation process and¬†give the¬†patina a¬†darker color. Frequent changes in¬†dry and¬†wet conditions will also accelerate oxidation.

types of¬†COR-TEN¬ģ

There are 5 types of¬†corten: cold-rolled COR-TEN¬ģ A, hot-rolled COR-TEN¬ģ A, COR-TEN¬ģ B, C, and¬†D. You can find more on¬†ssab website

With which materials to use

Wood, glass, concrete, and bricks are the perfect combinations for corten steel. As always in architecture, you are allowed to use up to 3 different materials for the façade. The most popular combination is: concrete, glass, and corten steel.

WU, glass, corten steel with a small amount of metal on the other side


Corten steel Sheet is also excellent for¬†a¬†variety of¬†punching styles. Round, square or¬†rectangular holes, texts, logos, images¬†‚Äď the¬†possibilities are practically unlimited. The¬†backlighting of¬†the¬†panels will highlight the¬†selected design.


I have found two types of¬†corten steel¬†‚Äď the¬†normal one and¬†the¬†weathered corten steel. I guess the¬†weathered steel has higher protection from rain etc.

The corten weathered steel sheet costs from 41£ (55$) per m2 with 1.5mm width to 200£ (250$) with a width of 6 mm.

The corten weathered steel sheet costs from 120£ (150$) per m2 with 1.5mm width to 350£ (450$) with a width of 6 mm.
However, this is a retail price; the wholesale price will be lower. The company that I used to get the price is located in the UK; their prices for labor are high. Therefore, in Russia, this technology costs less.

note: the dollar prices are not precise, and the price excludes VAT

Green roof

A green roof is a sustainable and ecologically friendly solution.

Types of flowers

There are 2 flowers available: sedum and wildflower. A sedum blanket system requires less growing medium than a wildflower blanket system.

The retail price for sedum is 40£/m2

The¬†price is mentioned without VAT in¬†¬£, where 1¬£¬†= 1.17‚ā¨¬†= 1.38$. The¬†price in¬†Europe is lower.
