Foldable, ultra-lightweight tricycle having an electric motor
First Claim
1. Ultralight tricycle with electric propulsion comprisinga base frame (15) fitted with two front wheels and one driving back wheel (9),an electric engine (10) to drive said driving wheel,a powering battery (11) to provide electric current to said electric engine and,a driving shaft (3) extending from the base frame and including a steering wheel (4) to be maneuvered by a user to control steering and speed of the tricycle,the tricycle being designed to switch from an unfolded configuration where said driving shaft is in a position almost perpendicular to said base frame and bound to it in order to allow the user positioned on the base frame to maneuver said steering wheel to ride the tricycle, to a folded configuration where said driving shaft is lowered toward the base frame to allow the user to seize said steering wheel to pull the tricycle rolling on its two front wheels while keeping the rear wheel away from the ground;
- said tricycle further comprisinga tachymeter to measure a speed of the tricycle anda slowing down/braking command unit (20, 20bis) connected to said tachymeter and suited to command transformation of said engine into a generator of electric current provided to said battery when the speed of said tricycle exceeds a preset speed ranging from 20 km/h to 30 km/h in order for the tricycle to slow down as a result of said engine becoming a generator and acting like a brake.

Abstract
Ultralight tricycle with electric engine including a base frame (15) fitted with two front wheels and one driving back wheel (9), an electric engine propelling the driving wheel, and one steering wheel (3) including a steering wheel (4) maneuvered by the user in order to control the steering and/or speed of the tricycle, the tricycle being designed to switch from the unfolded configuration allowing the user positioned on the base frame to ride the tricycle into a folded configuration enabling the user to seize the steering wheel in order to have the tricycle rolling on its two front wheels while keeping the back wheel away from the ground. The tricycle includes a tachymeter that measures the speed of the tricycle and one slowing down/braking command unit connected to the tachymeter and suited to command the transformation of the engine into a generator of electric current provided to a battery when the speed of the engine exceeds a preset speed ranging between 20 km/h and 30 km/h so that the tricycle slows down as a result of the engine being turned into a generator acts as a brake.
