Case Study


Deliver battle-tested proof of concept of a new electric scooter for Lime. Fix the existing fleet problems in cooperation with the Warsaw office to provide Lime users the best micromobility experience.

Mission Complete


  • Fix the burning vehicle control unit

    Mysterious problem with burning control unit deactivated more than 10k scooters a year. We had to identify the reasons behind it and eliminate the issue.

  • Fix battery functional safety issues in electric bikes

    Battery safety is a critical issue for every electric vehicle.

  • Fix the GPS problem

    When users are unable to locate the vehicle, they resign from Lime’s services.

  • Build the proof of concept of a new electric scooter

Mission Timeline


  • GPS
  • GSM
  • Motor Controller
  • Hardware-in-the-loop (HIL) Testing
  • Internet of Things (IoT)
  • Battery Management System (BMS)


  • We identified unique conditions that caused the control unit to overheat. We proposed 3 alternative solutions to eliminate the costs of repairing 10k scooters a year.
  • We found the long lasting issue with GPS accuracy. Users can now quickly locate the nearest vehicle.
  • We presented the concept of a new scooter system design along with the rideable proof of concept.
  • We helped to fix BMS (Battery Management System) functional safety features in Lime’s electric bikes, securing functional safety.

Client’s Testimonial

I partnered with Krzysztof to create a self-sufficient engineering team supporting Lime’s operational needs of markets throughout the EU and Middle East. We needed to establish technical competency and implement procedures to support relaunching Lime services in over 60 cities across 25 markets as the world emerged from COVID-19 lockdowns in the Spring and Summer of 2020. Working closely with Krzysztof, SquadTec recruited a team of 12 experienced and specifically skilled engineers in less than 2 months. A testament to his leadership and the potential of this product development team!

Krzysztof and the growing team assessed, proposed and implemented Agile tools and operating principles that were immediately applied to Lime’s product development process across internal and external teams in the EU, North America and Asia. They were patient, instructive, dedicated and driven to achieve successful outcomes for all. Collectively, we were able to address and correct inherited technical issues associated with positional accuracy, battery charging, maintenance and safety, and design a working, proof-of-concept system architecture, encompassing HW, FW and SW services, for a new generation of electric scooters.

I am confident that Krzysztof and the teams at SquadTec can make an immediate and lasting impact on just about any product development challenge you throw at them.
