Claim:
1. A tiltable electric tricycle comprises: (a) a front frame, (b) a front fork mounted to the frame, (c) a front wheel with a hub motor, (d) a seat, (e) a steering handle bar, (f) a pair of laterally spaced rear wheels on a common axle, (g) a rear frame with a horizontal support element for the rear wheels and a shaft attached perpendicularly to the horizontal support element, (h) a pair of footrests, (i) a battery to power the hub motor; furthermore the front frame has a bottom tube oriented along an axis line pointing to the ground contact point of the front wheel and the shaft of the rear frame is inserted into the bottom tube of the front frame and thereby is rotatably connected to the front frame; furthermore the front frame has a horizontally oriented metal plate at the rear end of the bottom tube positioned above the support element of the rear frame to restrict the extent of tilting of the front frame relative to the rear frame, and when the front frame is tilted relative to the rear wheel support element to a certain extent, an end of the metal plate touches the rear wheel support element and thereby limit the extent of tilting of the front frame; furthermore the rear frame has two quick release clamps on the support element for securing the axle of the rear wheels and the axle of the rear wheels can be released quickly from the quick lease clamps so that the axle with two rear wheels can be separated from the rest of the tricycle for easy transportation.
