Bicycle, modifiable for uphill, downhill and/or trail conditions

A bicycle comprising a Frame (1), a Front Wheel (9), a Rear Wheel (10), a Drivetrain Assembly (11), a Pedal Assembly (6), a Seat Assembly (5), Handlebar Assembly (7), a hard Tail (2) or a movable Tail (2), which is supported by a Suspension Assembly (4) and a hard Fork (3) or a telescopic Fork (3), the mutually slidable parts of which are interconnected by a Suspension Assembly (4),

• wherein a center of the Front Wheel (9), a center of the Rear Wheel (10), a Bottom Bracket (6.1) center, a Seat (5.1) connection and a Handlebar (7.1) connection form the vertices of a pentagon, the shape of which is slope-modifiable by at least one positionally adjustable vertex, when Suspension Assemblies (4) are unloaded,
• wherein
• the position of the Bottom Bracket (6.1) center is adjustable by means of the Pedal Assembly (6), which has one connection movably attached to the rear side of the Tail (2) or to the Rear Wheel Axle (10.1) of the Rear Wheel (10) by means of a Spacing Unit (6.3) and the other connection rotatably and slidably attached to the Frame (1) or to the Seat Assembly (5) or to the front side of the Tail (2) by means of a Support Unit (6.2), wherein this connection is lockable against sliding by a Bottom Bracket Lock (6.4);
• the position of the Seat (5.1) connection is adjustable by means of the Seat Assembly (5), having a Seat Carrier (5.3) movably attached to the Frame (1) by two slidable Connections (5.4) and (5.5) and is lockable by a Seat Lock (5.6), wherein the Pedal Assembly (6) is movably attached to the Frame (1), by a hard connection of the Bottom Bracket (6.1) to the movable Tail (2), or by connection of the Bottom Bracket (6.1) concurrently with two movable connections, where the first of them is provided by means of the Distancing Unit (6.3) to the rear end of the Tail (2) or to the Rear Wheel Axle (10.1) and the second one by means of the Support Unit (6.2) to the Frame (1) or to the Seat Assembly (5);
• the position of the Handlebar (7.1) connection is adjustable by means of the Handlebar Assembly (7), having the Handlebar (7.1) attached movably with respect to the Fork (3) by means of the Handlebar Carrier (7.2) and lockable by a Handlebar Lock (7.3) and/or a Handlebar Carrier Lock (7.4);
• the position of the Rear Wheel (10) center is adjustable by means of the Tail (2), which is movably connected to the Frame (1), wherein there is also other connection of the Tail (2) to the Frame (1) by the Suspension Assembly (4) and a Regulating Assembly (8), containing an Extensible Joint (8.6), wherein the position of the Tail (2) with respect to the Frame (1) is adjustable and lockable by the Regulating Assembly (8), when the Suspension Assembly (4) is unloaded;
• the position of the Front Wheel (9) center is adjustable by means of the telescopic Fork (3), the mutually slidable parts of which are interconnected by the Suspension Assembly (4) and by the Regulating Assembly (8), containing a Reducible Joint (8.7), wherein the mutual position of the slidable parts of the telescopic Fork (3) is adjustable and lockable by the Regulating Assembly (8) when the Suspension Assembly (4) is unloaded.
