SAFE BOSCH SPEED LOCK - NO ERROR CODE 504 Remove the factory 25km/h speed limit and unlock support up to 37km/h. The EPAspeed Box is precisely calibrated to stay below Bosch's tamper protection threshold (35-37 km/h), which helps prevent error code 504 and avoid activation of emergency running mode.
Quick tool-free installation: the integrated snap locking system allows installation in seconds. Simply place the EPAspeed box over the speed sensor near the rear wheel and reposition the magnet. No cables, tools or software modifications required.
Designed for durability and reliability: with a reinforced slim housing, automotive grade potting compound, carbon fibre finish and durable AAA battery, the EPAspeed Box is built to withstand vibrations, moisture and demanding e-MTB driving conditions.
BOSCH-SAFE SPEED DISPLAY RATIO To maintain system stability and avoid anti-tampering detection, the display shows the speed with a ratio of 1:1.5: display shows 20 km/h → real speed 30 km/h display shows 25 km/h → real speed 37 km/h (±1 km/h). The EPAspeed box remains the only completely contactless tuntuning module that maintains the function of the speedometer without the need for smartphone apps or GPS devices.
100% touch-free tuning technology: unlike conventional tuning chips that require wiring or access to the motor, the EPAspeed Box uses advanced wireless non-contact tuning technology and transmits a modified signal without changing the Bosch engine software, firmware or electronics.
