According to some embodiments, a manually-powered movable device comprises at least one wheel configured to move when a user operates the device, an electrical energy generating assembly, wherein the electrical energy generating assembly comprises a magnet assembly and a coil assembly, wherein the magnet assembly is configured to move when the at least one wheel is moved, wherein the coil assembly is configured to remain stationary relative to a frame of the device when the at least one wheel is moved, and wherein relative movement between the magnet assembly and the coil assembly generates electrical energy, at least one wire assembly coupled to the electrical energy generating assembly, and at least one output device coupled to the at least one wire assembly and configured to contribute to creation of a desired effect.

A bicycle light that is constructed and arranged to be supplied with input electrical power. The power can be supplied by multiple power sources, or not. When there are multiple power sources, the bicycle light includes a circuit that is adapted to deliver power to the light source from any of the power sources. The bicycle light can have an electrical power output, and a circuit that is adapted to deliver power to the light source and the power output.

A dynamic training system provides elevated load and energy demand on a rider of a moving bicycle out on the road or track. Resistance to movement of the bicycle is provided by a resistance unit which may include an eddy current brake. A processor may generate a control signal that adjusts the resistance to replicate the effort of riding a predetermined course or training protocol. Multiple riders at different times or locations can compete on a common virtual course. A stronger rider can be restrained by a heavier imposed load to keep pace together with a weaker rider, without compromising total power expenditure to keep the riders together.
