Smart chip of the 3rd generation with the possibility to set the speed limit of the e-bike. With the SpeedBox 3.0 tuning chip you can freely adjust the speed limiter of the e-bike. After installing the chip, the e-bike display shows real data such as maximum speed, average speed, daily distance and range. You activate the SpeedBox 3.0 chip on the e-bike display. After pressing the ‘Walk' button, the display briefly shows 9.9 km/h. From this moment you can drive with unlimited speeds - 40 km/h, 50 km/h and even more than 60 km/h. Press the ‘Walk' button again to cancel the chip function. The display shows 2.5 km/h and the speed limit of 25 km/h is switched on again. The e-bike then works as before installing the chip. We thought of e-bikes that do not have a classic control panel with walk button. In this case, simply use the combination ‘- + - +' . Then the SpeedBox is activated. You can also easily deactivate the SpeedBox. To set the maximum speed, change the mode: Turbo - Sport - Tour - Eco - Tour - Sport - Turbo. The current speed limit is then displayed. To change the top speed, briefly press the ‘Walk' button or turn the rear wheel 360°. The displayed speed of 2.5 corresponds to a top speed of 25 km/h, 3.0 corresponds to a maximum speed of 30 km/h or 9.9 corresponds to a maximum speed of 99 km/h etc.. The last displayed limit is saved after five seconds of inactivity. Includes: Crank arm puller. NOT COMPATIBLE WITH SMART SYSTEM!
