01 · Overview
The short version
Mimo started as a bike and scooter sharing product and later expanded into a broader mobility and charging ecosystem. The app needed to support multiple product categories: bikes, scooters, phone power banks, EV chargers and CarPlay experiences for EV charging. I worked with Mimo for more than five years as a freelance product designer, helping redesign the mobile app, evolve the product structure, design new product flows and support the transition from a single-purpose rental app into a multi-product mobility and charging experience.
02 · Context
Where it started
Mimo is a mobility and sharing product in Armenia. Public app store descriptions position it around bike, scooter, power bank and EV rental services, with users able to find nearby products, book, unlock, ride, charge and pay through the app. As the company added new product lines, the app had to evolve. A product that originally focused on scooters and bikes needed to support very different user intents: someone looking for a scooter, someone needing a phone charger, someone charging an EV, or someone using the experience from CarPlay. The challenge was to keep the app simple while the product ecosystem became more complex.
03 · Problem
What was broken
The main product challenge was designing a single app that could support multiple product categories without making the experience confusing.
- The app started around scooters and bikes, then expanded to power banks and EV charging.
- Each product had different user intent, usage context and interaction flow.
- Users needed quick access to the product closest to their current need.
- The homepage had to evolve from a single-product entry point into a multi-product discovery layer.
- EV charging introduced a different mental model than scooter or bike rental.
- CarPlay required a simplified in-car experience with minimal distraction.
- Hardware touchpoints needed to feel connected to the digital product experience.
- The product had to stay understandable for users who only came for one category, such as scooters, bikes, power banks or EV charging.
04 · My Role
Where I stood
I worked as a freelance product designer across multiple product phases for more than five years. My role included redesigning the mobile app experience; designing bike, scooter, power bank and EV charging rental flows; designing the CarPlay experience for EV charging; rethinking the homepage when Mimo became a multi-product app; designing the Fast Decision experience to help users quickly choose nearby products; designing advertising/story-style banner patterns inside the app; supporting visual and interface decisions for physical hardware touchpoints; and collaborating with the team and with a design colleague on product and hardware-related design. This was not only a UI redesign — it was a long-term product evolution project across mobile UX, service design, hardware touchpoints, multi-product IA and mobility experience design.

06 · Constraints
What shaped the approach
- The app had to support multiple product categories without overwhelming users.
- Different products had different usage contexts: riding, charging a phone, charging a car and using CarPlay.
- Users needed fast decisions based on location and availability.
- The product had to remain useful for users who came for only one category.
- EV charging and CarPlay required simpler, safety-conscious flows.
- Hardware touchpoints had to visually connect with the app experience.
- The homepage had to scale as more product lines were added.
07 · Process
How it moved
Initial app redesign
The work began with redesigning the app experience for bike and scooter sharing. The focus was on making discovery, booking, unlocking, riding and payment flows clearer and easier to use.
Multi-product expansion
As power banks and EV charging were added, the app needed a new structure. I worked on adapting the product experience so each category had its own logic while still feeling part of one system.
Homepage redesign
When Mimo became a multi-product app, the homepage had to become a product discovery layer. The goal was to help users understand what they could do immediately without forcing them through unnecessary complexity.
Fast Decision feature
The Fast Decision feature was designed to show the closest relevant products and help users quickly decide what to use. This supported real-world behavior: users often open the app because they need something nearby right now.
EV charging and CarPlay
EV charging introduced a different type of interaction, with longer sessions and different status information. CarPlay required an even simpler experience that could work safely in a car context.
Hardware touchpoints
Together with a colleague, I also worked on visual and interface-related design for physical charging stations and related product touchpoints, helping the digital and physical experience feel connected.
Story-style banners and communication
We added promotional and informational banners inspired by story-style patterns, giving the product a flexible way to communicate offers, updates and product messages inside the app.
08 · Key Decisions
Choices that mattered
Design Mimo as a multi-product system, not separate isolated features.
Why: Scooters, bikes, power banks and EV chargers needed different flows, but users still needed one coherent app experience.
Make the homepage a decision layer.
Why: As the product expanded, users needed a faster way to understand what was nearby and what action they could take immediately.
Use Fast Decision for location-based product choice.
Why: In mobility and charging use cases, proximity and availability are often more important than browsing. The experience needed to support quick, practical decisions.
Keep each product flow focused on its real-world context.
Why: A scooter ride, a phone charging session and an EV charging session are very different behaviors. The UX had to respect those differences.
Simplify CarPlay for the driving context.
Why: CarPlay experiences need to reduce distraction and focus only on essential actions and status information.
Connect digital and physical product design.
Why: Users interact with Mimo not only through the app, but also through scooters, bikes, power banks and charging stations. The experience needed to feel connected across touchpoints.
09 · Solution
What we built
The result was a more scalable product experience that could support Mimo's growing ecosystem of mobility and charging services. The app evolved from a bike/scooter sharing product into a multi-product experience with dedicated flows for scooters, bikes, power banks, EV charging, CarPlay and fast nearby product discovery.
- Bike and scooter rental UX
- Power bank rental UX
- EV charging flow
- CarPlay experience
- Multi-product homepage
- Fast Decision feature
- Story-style banner system
- Hardware touchpoint design
10 · Product UX
Designing for the team
The UX work focused on making a complex multi-product app feel simple in real use. The key was to help users quickly understand what is available, choose the right product and complete the relevant action without unnecessary friction.
- A homepage redesigned around multiple product categories.
- Fast Decision logic for nearby available products.
- Separate flows for scooters, bikes, power banks and EV charging.
- CarPlay experience for simplified EV charging interaction.
- Story-style banners for product communication.
- Hardware touchpoint visuals connected to the app experience.
- Scalable structure for future product additions.
11 · Impact
What changed
The work helped Mimo evolve from a bike and scooter sharing app into a broader multi-product mobility and charging platform. The redesigned product structure made it easier to support new services, create product-specific flows and give users faster access to nearby mobility and charging options.

13 · Key Learnings
What I keep
- This project reinforced that product complexity should not become user complexity. Adding new product lines is not only a feature problem — it is an information architecture, interaction design and service design challenge.
- The biggest lesson was that each product category needs its own flow, but the overall experience still needs one clear system. A successful multi-product app helps users act quickly without forcing them to understand the entire product ecosystem.
- It also showed how important it is to connect digital and physical touchpoints. In mobility and charging products, users experience the brand through the app, the vehicle, the station and the moment of use.
