Abstract: A system for estimating the behavior of a cyclist on a bicycle and/or of the quality of a road along a path followed by said bicycle, comprising: a sensor configured to detect the vertical acceleration of the bicycle and to supply a signal representative of the same; a module for estimating vertical impacts configured to: receive at the input the signal representative of the vertical acceleration for a determined time; acknowledge one or more first portions of the signal representative of the vertical acceleration, containing peaks due to vertical impacts, and one or more second portions of the signal representative of the vertical acceleration devoid of said peaks due to vertical impacts, wherein said one or more first portions of the signal representative of the vertical acceleration are indicative of the cyclist's behavior, and said one or more second portions of the signal representative of the vertical acceleration are indicative of the road quality.

Abstract: A system (1) for controlling the motion of an impulsive-type human-powered vehicle (100), includes: a motor (2) associable to at least one vehicle (100) driving element, suitable for generating a total torque/driving force (T); a system (4) for storing energy to be supplied to the motor (2); a sensor (5) for detecting the vehicle (100) longitudinal speed (v); a module (7) for controlling a main torque/driving force (T?) of the motor (2) based on at least the signal representative of the vehicle (100) longitudinal speed (v); a module (9) for determining the vehicle longitudinal acceleration (Ax); a module (8) for estimating the presence or absence of a thrust (Fk) of the user on the vehicle (100); an activation signal when it is estimated the absence of the thrust (Fk) of the user: a deactivation signal when it is estimated the presence of the thrust (Fk) of the user.

Abstract: A dynamo that is connectable to a wheel of a bicycle may include an electric machine capable of alternatively operating as a generator and as a motor and one or more batteries connected to the electric machine in order to be capable of exchanging energy with this latter. The dynamo may also include a control unit configured for commanding the electric machine according to a first mode, wherein the electric machine acts as a generator and is capable of converting rotational mechanical energy of the wheel into electric energy to be stored in the one or more batteries, and according to a second mode, wherein the electric machine acts as a motor and is capable of delivering additional power to the bicycle wheel by withdrawing energy from the one or more batteries. The dynamo may further include one or more command members connected to the control unit.
