1. A straddle-type electric vehicle comprising:
- a rear wheel;
a front wheel;
an electric motor that drives the rear wheel;
a steering handle that turns with the front wheel;
a plurality of operation members that are operated by a driver, the plurality of operation members being mounted on the steering handle and including an accelerator operation member;
a vehicle controller electrically connected to the plurality of operation members and configured or programmed to output an instruction value based on at least an amount of operation of the accelerator operation member;
a motor driving unit electrically connected to the vehicle controller and that supplies a driving electric power to the electric motor in accordance with the instruction value; and
a case including the motor driving unit disposed therein;
whereinthe vehicle controller is disposed outside the case;
a distance from the steering handle to the vehicle controller is shorter than a distance from the steering handle to the motor driving unit in a side view of the vehicle;

Abstract
An electric motorcycle includes a vehicle controller that outputs an instruction value based on an operation amount of at least an accelerator grip, and a motor driving unit that supplies a driving electric power in accordance with the instruction value to an electric motor. The vehicle controller is disposed outside a case that includes the motor driving unit disposed therein. The distance from the steering handle to the vehicle controller is shorter than the distance from the steering handle to the motor driving unit in a side view of the vehicle body, to simplify the cost of the electric wire and the work required to lay out the electric wire.
