ABSTRACT:
A bicycle seat power adjustment mechanism includes a two-direction activation switch mounted on the handlebars and a power supply mounted on the bike frame or under the seat. The power supply would typically be a battery pack, and may be used in conjunction with a generator powered by the motion of the bicycle. An electric motor drives a bevel gear combination that causes an interior drive shaft to rotate. The drive shaft is contained within the seat mounting post and a receiving member of the bike frame. The drive shaft is threaded so that, depending upon the direction of rotation, the drive shaft is moved up and down within a seat post receiving member of the bicycle frame. The direction of rotation is controlled by the activation switch. A rotation inhibition mechanism is provided so that the seat does not tend to rotate when the device is activated.
