Business Context

1

Post-IPO Scale Pressure

Following its 2024 IPO, FLYE entered an accelerated expansion phase requiring standardized, scalable operations across 40+ physical locations, with continued expansion into new markets.

2

Fragmented, Offline-Driven Operations

Without an integrated digital infrastructure, operations relied heavily on manual coordination, scattered spreadsheets, and multiple third-party tools resulting in workflow fragmentation, operational friction, and limited scalability.

3

Rental Became a Core Growth Pillar

To enhance capital efficiency and unlock recurring revenue, rental was positioned as the foundation for scalable, asset-light growth.

Outcome

Customer-facing
iOS & Android app

SaaS platform for office
and store operations

Impact

Significantly improved operational efficiency across all departments

The Challenges

Navigate Ambiguity

Both the product structure and business rules were undefined at the start. Without a PM, "Build an app for our rental business." was the only brief I got. From there, I defined the requirements, pulled in the stakeholders, led the research, and delivered the end-to-end design process.

Driving alignment in environments without design culture

In an organization driven by sales and finance rather than product, it's difficult to advance a complete design process.

Phase 1 - Discover

Scope

The rental product line is where the digital transformation begins.

The first launch prioritizes the Rental Module (Flex Rental and Rent-to-Own) on top of a shared Infrastructure Layer that will eventually support other business lines like Retail, Repair, and Protection Plans.

Research 1: Concierge MVP

Behavioral Research through a Lean Concierge MVP

Before investing in a full digital product, we first validated the business model with lightweight tools a Wix landing page, in-store posters, QR codes, pricing sheets, and manual spreadsheet tracking.

What have we clarified from the Concierge MVP

01

Operational workflows and user Journey

02

Problems hindering business scaling

03

Multi-stakeholder needs and pain points

Research 2: Competitive Analysis

Competitors sacrifice one side of each trade-off. We can win by designing for both:

Onboarding Speed vs Predictability

Transparency vs Cognitive Load

Flexibility vs Control

Research 3: Vendor Research

Determining whether to buy or build for each part.

Phase 2 - Define

Personas

Three key personas

Rent-To-Own Customer

Age: 29 | Delivery Courier

" I can't afford a full upfront purchase but needs immediate access to a reliable bike. "

Complete onboarding as quickly as possible.

Understand total payment and ownership timeline

Track payment status clearly

Flex Rental Customer

Age: 23 | Graduate Student

" E-bikes would make getting to the beach with friends this weekend much easier. "

Pick-up / Drop-off easily

Avoid hidden fees

Get a bike immediately without large upfront cost Understand total payment and ownership timeline Track payment status clearly

Store Staff

Age: 32 | FLYE Store Staff

" I hope the rental process is simple, since I have many retail and repair customers to handle  "

Saving time on contract preparation and answering customer inquiries.

Sync inventory, orders, and related information smoothly.

Avoid mistakes in payment or contract records

Rent-To-Own User Journey

Flex Rental User Journey

Problems

Problem 1

Excessive Manual Data Entry

Manual data entry is time-consuming and error-prone especially for Rent-To-Own contracts, where staff must enter customer and order information separately into both the contract and the backend system.

Problem 2

Information Overload

The website already contains all the information customers need, but since it's presented all at once without stage-by-stage guidance, customers still frequently ask staff questions that are already on the site.

Problem 3

Inventory Coordination

Running retail and rental in parallel means a larger vehicle selection, with a complex bike lifecycle to manage. Depreciation data was tracked manually, and group rentals make inventory coordination even harder.

Problem 4

Lack of Self-Service Path

All payments go through staff via POS. Installment payments for RTO frequently run into issues, requiring customer service to constantly follow up and resolve.

Rebranding

Correct the Positioning to lay the Digital Transformation Foundation

1. Match the Logo System with the Business Model

Before

Appears as a low-end DTC brand

Failed to reflect the brand's full service-driven DNA

One Logo for Everything: Blurring accountability for third-party product

The brand name Fly E-Bike could not be trademarked

Inconsistent logo & wordmark usage

After

A full-service urban e-mobility platform

Clear brand architecture separating products, services and platforms

Preserved brand recognition while evolving the identity

Consistent visual identity across all touchpoints

Available for trademark

2. Reinforce the Brand Value through a new Slogan

Before

This is not real us

What differentiate us from other e-mobility brands and why our our customer love us:

Professional Services

Friendly staff

Extensive store network

After

This is us!

  1. Author a brand book to ensure brand consistency across digital and physical touchpoints.

Phase 3 - Develop

Process Artifacts

Aligned with stakeholders through different deliverables to clarify and validate requirements.

Iterations

Mobile App: Iteration as Validation & Refinement before development

Can users complete critical tasks independently without external guidance?

Example 1: [ "Ready for pickup" status page for the RTO order ]

Goals:

Guide customers to pick up their e-bike at the store.

Consolidate essential order details into an easy-to-scan view.

Learnings

  1. What I Learned from Addressing These Challenges

Navigate Ambiguity

Break things down into steps and tackle them step by step.

Get something out quickly to trigger feedback.

Strategic focus > Perfectionism

Driving alignment in environments without design culture

Frame design as a business tool, that's what earns buy-in.

Visual artifacts drive stronger buy-in than text alone

Be confident as the design decision-maker. Hesitation shifts the burden onto others and makes it harder to earn trust.

  1. What I Would Do Differently

Advocating for adequate resources early

I took on responsibilities as a design lead role early than I expected in this project. So I underestimated the scope as it came. In addition to leading this project, I was also handling marketing, brand, and other design tasks across the company. I had to work overtime every day to keep up with the workload.

Looking back, I would have communicated the project scope earlier and advocated for additional design resources. This experience taught me to assess challenges honestly and communicate them early.

Build the design system early

I held off on building the design system until after the second version of lo-fi prototype which meant dealing with inconsistent components and a lot of cleanup later. Starting it earlier would have saved time and kept things more consistent, without getting in the way of creative exploration.
