  Next, (3) power running will be described. FIG.6 (c) is a figure which shows the riding method which rides using the driving force of the said electric motor. A wheel-in motor and a one-way clutch (not shown) are fitted to the axle of the front wheel 20, and a rotation switch (not shown) built in the right handle grip 41 at the tip of the handle bar 43 is inserted to install an electric motor. When activated, the output of the electric motor is transmitted to the axle of the front wheel 20 via the one-way clutch, and travels with power. In such power running, the electric motor is started from the stopped state of the electric three-wheel kick skater, and when the predetermined speed is reached from the beginning, both feet are aligned with the footrest plate in parallel and standing on the footrest plate. You may ride on it.

  Further, (4) the case of running with kick and power will be described. In the combined use of kick and power, at the start of movement, the travel is started by placing one foot on the footrest plate front portion 62 and kicking the rear ground with the other foot. When a certain speed is reached, both feet are aligned with the footrest plate in parallel and stand on the footrest plate, the switch is turned on, the electric motor is activated, and the vehicle runs with power. In this case, since the one-way clutch is fitted to the front wheel axle as described above, there is no sudden acceleration or sudden deceleration due to the rotation of the electric motor when the electric motor is started, and the vehicle shifts to power running with a smooth movement. And when running continuously, the burden on an electric motor can be reduced by sometimes using kick running together.
