The Mobile Bar

The Mobile Bar is a mobile coffee bar from the Vogelenbuurt in Utrecht Noordoost. The business does not have a fixed public location. The bar is set up at varying spots in the neighborhood, depending on the weather and schedule. According to the company, current times and locations are shared via Instagram. The mention of Hopakker 59 on Google Maps is outdated, as no coffee is sold there anymore.

Behind The Mobile Bar are the identical twin brothers Sens and Imme Gerritsen. They were born in 2006 and grew up in Utrecht. After attending Het Zonnewiel primary school in De Bilt, they completed their havo (pre-university education) at the Stichtse Vrije School in Zeist.

The first mobile bar originated as a profile paper for high school. The brothers bought a second-hand espresso machine and designed and built the bar themselves. In May 2023, they also submitted the accompanying research and business plan. A business registration lists April 2023 as the start date of the enterprise, under KvK number 89961412.

According to the brothers, their first instructions on working as a barista came from their half-brother. In the summer of 2023, they began serving neighbors. To do this, they opened the garage where the mobile bar was stored.

The concept revolves around coffee, tea, and related products from bars that can be transported by bicycle or cargo bike. Within Utrecht and the immediate surroundings, the business uses a cargo bike. For more distant destinations, an electric delivery van is used.

Activities include street sales and participation in private, corporate, and cultural events. The Mobile Bar now reports having two mobile bars. This allows the business to operate at two locations simultaneously. It is not a regular cafe with fixed opening hours, but a mobile setup with a varying program.

For coffee, The Mobile Bar uses Fairtrade coffee from BOOT Koffie. Various organic teas from this supplier are also on the menu. In addition, hot chocolate, decaffeinated coffee, cow’s milk, and plant-based milk are mentioned.

The larger bar operates with a two-group Sanremo D8 espresso machine. Previously, a Wega IO was used. The smaller bar uses a two-group Sanremo Zoë Compact. Available information primarily describes espresso and espresso-based drinks. Manual filter methods, such as pour-over, AeroPress, or French press, are not publicly documented.

The menu changes partly with the season. In summer, iced coffee drinks are mentioned. For autumn, the company mentions pumpkin-spice latte. An early menu description listed, in addition to coffee specialties, fresh tea and hot chocolate.

According to the founders, the mobile bar was present at neighborhood and cultural events such as those hosted by IJsclub Siberia, the Klapstoelconcerten, UITfeest, Tweetakt, and Le Guess Who? at TivoliVredenburg. The company also lists weddings, birthdays, corporate gatherings, openings, open days, and multi-day festivals as types of assignments.

Makers/ROCMN published posts about activities featuring The Mobile Bar, free coffee or tea, and a barista workshop. The available text does not clearly indicate whether Sens and Imme conducted the workshop themselves. The company also collaborated with ice cream parlor Il Mulino on a temporary winter café, scheduled for weekends from December 13 to February 15.

Recurring tastings, public cuppings, or independently organized exhibitions are not publicly documented.

The Mobile Bar states that it considers origin when making product choices. The Fairtrade coffee used comes from BOOT Koffie, which, according to available information, maintains direct relationships with coffee farmers. The operators make some of the baked goods themselves. Other products come from the local supplier BijGijs, which offers products without added sugar and options without gluten or lactose.

No public information was found regarding reusable cups, waste measurements, water consumption, renewable energy, or published emission data. As a result, a broader assessment of environmental performance is not possible based on the available material.

Votulastkrant published a profile on the brothers and the origin of the bar in December 2023. The Nuk followed up with an article on July 31, 2024, and also distributed a video version. A profile appeared in Het Financieele Dagblad on July 29, 2025.

No coffee prices, formal rankings, or mentions on award lists were found in the examined public sources. The available reporting focuses primarily on the young founders, the school project, and the development toward mobile entrepreneurship.
