## Abstract

To produce an elliptical bicycle that can be used by persons of all ages safely, comfortably and easily, a bicycle with simple and original mechanisms has been created, allowing the user to feel safe when mounting the bicycle and to be able to handle same with ease and pleasure and to enjoy the journey. Using these original designs and mechanisms, a compact bicycle has been created, which is made easy and safe to move from one place to another by the ability to lower the handlebars and at the same time collapse the steering column and by a simple, silent, compact drive system formed by footboards, pedals, a bottom bracket and wheels. The bicycle has the advantage of providing easy and safe travel and has a gear-shifting system that can have between 3 and 12 different speeds and a caliper braking system on the rear and front wheels.

## Claims

### Claim 1

Urban elliptical bicycle with safe, easy and comfortable maneuverability, which includes a main body, handlebars, bottom bracket shell with pedals, connected by means of a chain to a geared hub and footboards, CHARACTERIZED in that it is made up of a pair of pedals (4), one of them with a crankset (5), both pedals (4) coupled on each end to an axle (6) located inside a bottom bracket shell (3) by means of 2 bearings and mounted on said shell, on two bearings, is a rear wheel (2) with a gear (7A) attached, to which a chain (8A) is coupled which, in turn, couples to another similar gear (7C) attached to one end of a variable geared hub (12); a chain (8B) is coupled to the crankset (5) connecting to a gear (7B) attached to the end of a variable geared hub (12).

### Claim 2 (depends on 1)

The Urban elliptical bicycle with safe, easy and comfortable maneuverability according to claim 1, CHARACTERIZED in that from each end of the pedals (4) an arm (14) is connected by means of a bearing, wherein the footboards (15) are arranged, and on the other end of this arm a sealed linear bearing (16) is arranged which moves on a cylindrical shaft (17) supported by means of two supports (19) attached to the main body of the bicycle (1).

### Claim 3 (depends on 1)

The Urban elliptical bicycle with safe, easy and comfortable maneuverability according to claim 1, CHARACTERIZED in that the main body has a total length between 130 and 150 cm and a height between 100 and 135 cm.

### Claim 4 (depends on 1)

The Urban elliptical bicycle with safe, easy and comfortable maneuverability according to claim 1, CHARACTERIZED in that it has a steering column (24) that is foldable by means of an adjustment clamp (27), and arranged on this column are the handlebars (26), the height thereof able to be adjusted by means of an adjustable adjustment pin (25).
