The most likely and immediate reason your e-bike has power but won't move in the rain is the automatic power-cut feature in the controller, a standard safety mechanism to prevent short circuits and electrical hazards. In the UAE, sudden, heavy downpours common in winter months can quickly overwhelm the water resistance of many consumer-grade e-bikes. The controller, acting like the bike's ECU, detects moisture ingress and shuts down the motor system, even if the battery and display still have power. According to advisories from the RTA Dubai regarding micro-mobility vehicle safety, water-related electrical faults are a leading cause of roadside malfunctions. A 2023 report by the UAE Ministry of Energy and Infrastructure on sustainable transport noted the need for enhanced ingress protection (IP) ratings for vehicles in the region's climate. If this happens, do not repeatedly attempt to restart it. Safely move the bike to a dry, shaded area, disconnect the battery, and use a dry cloth to wipe external connectors and the controller housing. Allow it to dry thoroughly for 24-48 hours, preferably in an air-conditioned space, as humidity can slow the process. If it still doesn't work, the controller or a sensor (like the brake cut-off sensor) may need professional inspection, as internal corrosion can occur. For popular models sold here like the MG ZS EV (for comparison's scale) or e-bikes from AW ROSTAMANI or Al-Futtaim dealers, always visit an authorized service center to maintain warranty and ensure correct, safe repairs. The cost of a controller replacement in the UAE can range from AED 300 to AED 800, depending on the model, which is a key factor in the total cost of ownership for an e-bike in the long run.
