2 rubber plug for the front drive contact The rubber plug are equipped with a nose and trigger under pressure contact of the underlying sensors. The function is contactless. The welds on the aluminum frame are all neat and clean executed In the rear driving contact plate two rubber plugs are also used, which triggers the rear sensors of the TROTTER. The sensor board are screwed below the contact plate. All four sensors activate the driving contact. A SAMSUNG battery with an output of 48 V 4.4 AH is built into the TROTTER. Under the front driving contact plate is the sensor board of the front driving contact screwed. The control plate is installed in the front part of TROTTER. At the same location in the back the battery is installed. This part of TROTTER is protected with a sealant against water penetration. I have now switched on the TROTTER. The driving process is triggered when both driving contact sides are pressed. Forward weight triggers the driving process from the front and vice versa. Here you can see the absolutely solid framework of TROTTER. The wheel is on the left side of TROTTER slightly recessed to accommodate the tire fill. The rim on the right is manufactured very nice and under the outer cover is the driving motor. By unwanted descents from the TROTTER, it develops little scratches which aren’t very noticeable. The front and rear bumpers are well manufactured and fitting in the frame. As a wear and tear part is not the bumper, but behind an inserted single metal plate. The axle is inserted from below into the frame and secured with a fitting and 4 screws on each side. This gives a clean look of TROTTER because you can’t see the suspension while driving. I have unfortunately filmed the power supply upside down. The data is later displayed. The connection box for the charger is located on the TROTTER’s back. Just opposite to the on-off switch. Here, the light flashes red and green, which refers to a charged TROTTER. After switching the Trotter on, 3 light flashs and 3 beep tones signalize the readiness for use. The start of the TROTTER is somewhat bumpy in the beginning, since the board immediately switches to the driving mode, when both driving contacts are triggered. The TROTTER has excellent carving properties and tight curves make fun. Removing the feet of the driving contacts stops TROTTER.
