Torque sensors and power controls were developed in the late 1990s. For example, Takada Yutky of Japan filed a patent in 1997 for such a device. In 1992 Vector Services Limited offered and sold an e-bike dubbed Zike.[9] The bicycle included NiCd batteries that were built into a frame member and included an 850 g permanent-magnet motor. Despite the Zike, in 1992 hardly any commercial e-bikes were available.
With different degrees of assistance at your fingertips, riders of varying fitness levels are easily accommodated on the same ride too. Which, depending on who’s setting the pace, can bring a social aspect back to big days out, because you can all ride together and the assistance from the motor makes it that much easier to string a coherent sentence together even on the steepest climbs.

What does this mean for anyone with Stark Drive that was backed with greater then a 250W motor? Quite simply, it means that as long as you have not modified Stark Drive in any way, and depending on your local countries regulations (if they differe with this EU Standard) you are now able to use your bike legally in your location no matter where you are in the EU.
Where in the fitness manual does it say that getting fit has to mean suffering? Nope, being active is getting the heart rate up and keeping the mojo high. The Crossroads is your key to weeknight workouts and rides with the family, offering a refreshing change from treadmills and dumbbells. And with the benefits of a Body Geometry saddle and grips, it's one bike that’ll keep you riding with a face that says 'joy' more than 'suffering.'

An electric bicycle, also known as an e-bike, powerbike or booster bike, is a bicycle with an integrated electric motor which can be used for propulsion. Many kinds of e-bikes are available worldwide, from e-bikes that only have a small motor to assist the rider's pedal-power (i.e., pedelecs) to somewhat more powerful e-bikes which tend closer to moped-style functionality: all, however, retain the ability to be pedalled by the rider and are therefore not electric motorcycles.
