Any of the three bikes with an X suffix denotes that the motor is a 1000 watt motor without a set speed restriction as compared to the speed limit 750 watt version. The Wavecrest Tidalforce M-750 was based on The original military experimental M-313 model. The M-313/M-750X was the first electric bike to be made and tested by Wavecrest Labs.

Nameplates on electrical motors show their power output, not the power input (the power delivered at the shaft, not the power consumed to drive the motor). This power output is ordinarily stated in watts or kilowatts. In the United States, the power output is stated in horsepower which, for this purpose, is defined as exactly 746 watts.
A much larger capacity VFR model, the VFR1200F, was revealed at the Tokyo Motor Show in October 2009. [3] [4] The new 1,200 cc (73 cu in) narrow-angle SOHC V4 engine [5] does not use the V-Tec design of the smaller VFRs. It has an optional six-speed push-button operated dual clutch transmission with three modes: automatic, sport and manual.
In terms of electromagnetism, one watt is the rate at which electrical work is performed when a current of one ampere (A) flows across an electrical potential difference of one volt (V), meaning the watt is equivalent to the volt-ampere (the latter unit, however, is used for a different quantity from the real power of an electrical circuit).
The motor from a 3.5 in floppy disk drive. The coils, arranged radially, are made from copper wire coated with blue insulation. The rotor (upper right) has been removed and turned upside-down. The gray ring inside its cup is a permanent magnet. This particular motor is an outrunner, with the stator inside the rotor. DC brushless ducted fan. The ...
For electrical motors, a similar kind of information is conveyed by the service factor, which is a multiplier that, when applied to the rated output power, gives the power level a motor can sustain for shorter periods of time. The service factor is typically in the 1.15-1.4 range, with the figure being lower for higher-power motors.
Boulton & Watt engine of 1788. Centrifugal governors were invented by Christiaan Huygens and used to regulate the distance and pressure between millstones in windmills in the 17th century. [4] [5] James Watt designed his first governor in 1788 following a suggestion from his business partner Matthew Boulton.
