Enyring : support for e-bikes development with swappable batteries
ENYRING, a subsidiary of Yamaha Group, is developing an innovative mobility solution. Based on a Battery-as-a-Service approach, it combines eBikes, battery management infrastructure, battery swap stations, and a mobile app into an integrated ecosystem. The goal is to make urban cycling more practical through smart product design and modular infrastructure.
Project abstract
ENYRING set out to design a fleet of intelligent electric bikes (City, Sport, Longtail and Cargo) built around a removable battery system. The aim was to allow users to easily recharge and swap batteries at dedicated stations in under a minute. The eBikes were designed to be robust, modular, and well-suited for shared urban use.
▪️ Solution
Kickmaker supported ENYRING from the early design phases to the development of the first functional prototypes, addressing mechanical, industrial, and logistical challenges. We focused on creating a modular design, simplifying assembly, and adapting key components to ENYRING’s unique technical and business requirements.
▪️ Objectives
We supported ENYRING’s teams in:
-
Mechanical development of the three models (MTB, hybrid, cargo)
-
Optimizing design for scalable, reliable industrial production
-
Preparing initial production series with detailed technical documentation (SOP)
-
Sourcing components aligned with performance specs and target costs
Technical developments
As a technical partner, Kickmaker played a key role in the mechanical design and production readiness of Enyring’s e-bikes.

-
Complete mechanical design using SolidWorks, including chassis, protective covers, battery/motor mount points, user interfaces, and accessories
- Design for Manufacturing (DFM) studies: part count reduction, material choices suitable for industrial processes (plastic injection, machined aluminum, welded tubing)
-
Development of functional prototypes to validate structural integrity, battery positioning, sensor integration, and user comfort
-
Design for Assembly (DFA): optimized assembly process, use of quick fasteners, and simplified production line workflows
-
Strategic sourcing: all components selected for reliability, availability, and compliance with EU standards
-
Technical documentation (SOP): illustrated assembly guides, part lists (BOM), end-of-line testing procedures, and quality control protocols
Key achievements
Thanks to our expertise in multi-disciplinary and multi-partner project management, in mechanical engineering, electronics and embedded software, in prototyping and preparation for mass production, we enabled ENYRING to:
-
Structure the entire bike range around a modular, scalable system
-
Validate key technical functions early on through mock-ups and functional POCs
-
Launch their initial production runs under controlled, industry-ready conditions
-
Build the foundation for future local or European manufacturing with market-specific sourcing
