Abstract: A swing arm extender includes a body portion having a first side and a distal second side. The first side has a shape and size for interfacing with a frame of a bike/trike at a location where a stock swing arm previously interfaced to the frame of the bike/trike and the second side (opposing the first side) has a size and shape for interfacing with the stock swing arm. There are seats in the first side where bearings are installed, and then a stock pivot pin is passed through the bearings and the frame of the bike/trike.

Abstract: A gear shifter includes a frame and a pivot frame pivotally mounted to the frame. A gear shift lever is pivotally interfaced to the pivot frame by a pivot pin passing through a bore in the gear shift lever. The gear shift lever extends upwardly beyond the frame and a lower section of the gear shift lever extends downwardly into the frame. A fastener passes at least partially though the gear shift lever and interfaces with the pivot pin such that, one position of the fastener locks the pivot pin within the gear shift lever and within the pivot frame and, a second position of the fastener frees the pivot pin from both, therefore facilitating removal of the gear shift lever. The lower section of the gear shift lever is interfaced to a first transmission linkage and the pivot frame is interfaced to a second transmission linkage.
