-\section{Research gap}
-Despite this progress, limited research has examined the adaptation of open-source motor controllers to LowTech and 
-repairability constraints. To date, researchers have not addressed the challenge of designing a controller that can 
-be locally fabricated, repaired with standard components, and secured against unauthorised wireless access requirements 
-that are critical for decentralised, community-operated fleets.
+\section{Research Gap}
+
+The literature presented in the previous sections shows that significant work has been carried out on BLDC 
+motor control strategies, especially for torque ripple reduction, efficiency improvement, and dynamic performance 
+optimisation. Open-source projects such as VESC also provide high-performance and flexible solutions for electric 
+mobility systems.
+
+However, most existing works mainly focus on control performance and do not consider low-tech constraints such as 
+local manufacturing, hardware repairability, or component accessibility. In many existing controllers, the hardware 
+design remains difficult to reproduce or repair without specialized equipment or advanced electronic knowledge.
+
+In addition, the integration of wireless communication introduces new security concerns. While BLE connectivity 
+simplifies configuration and monitoring, unauthorized access to controller parameters could create safety risks, 
+especially for electric cargo bikes operating in public spaces.
+
+To the best of our knowledge, there is currently no open-source motor controller that simultaneously addresses 
+high-performance control, local manufacturability, repairability, and BLE security for decentralized cargo bike 
+applications.
+
+This project therefore aims to explore a modular and repair-oriented motor controller architecture compatible 
+with VESC while remaining adapted to the constraints of the Manufacture Autonome Décentralisée (MAD).
