each one of said first and second folding mechanisms is configured to: a. position its bottom frame in a fixed position relative to its rear frame when said locking mechanism secures a locking frame to one of a rear end of said seat frame, and a seat connected with said seat frame; and b. enable its bottom frame to move when said locking frame is detached from said rear end of said seat frame or said seat, and its respective anchor and locking frame touch the ground. ### Claim 3 (depends on 2) The folding tricycle of claim 2, wherein said first and second folding mechanisms are further configured to enable folding of said first and second rear wheels towards each other in order to minimize the overall dimensions of said tricycle. ### Claim 4 (depends on 2) The folding tricycle of claim 2, further comprising: a wheel fork connected between said front wheel and said handlebar; said wheel fork is connected with said handlebar through said one of said front frame and said front bearing member. ### Claim 5 (depends on 1) The folding tricycle of claim 1, wherein said handlebar is telescopic. ### Claim 6 (depends on 1) The folding tricycle of claim 1, further comprising two safety bars connected with said seat frame. ### Claim 7 (depends on 1) The folding tricycle of claim 1, further comprising at least one telescopic bar connected with one of said seat frame and a seat. ### Claim 8 (depends on 7) The folding tricycle of claim 7, further comprising a handle connected with said at least one telescopic bar. ### Claim 9 (depends on 7) The folding tricycle of claim 7, further comprising a canopy connected with said at least one telescopic bar. ### Claim 10 (depends on 2) A method of folding a folding tricycle, comprising: a. providing the folding tricycle of claim 2; b. detaching said locking frame from one of said rear end of said seat frame and said seat; c. lowering said locking frame to the ground thereby lowering said first and second anchors to the ground; and d. pulling said seat frame towards said first and second rear wheels, thereby placing said front wheel in between said first and second rear wheels; and pushing said seat frame towards said handlebar, thereby folding said seat towards said handlebar. ### Claim 11 (depends on 1) The folding tricycle of claim 1, further comprising two sliding parts rotatably connected with one of said seat frame and a seat; and a parent bar connected with a second end of said first and second support frames; said locking mechanism connected with said sliding parts and further configured to secure said sliding parts to said parent bar in said unfolded position and release said sliding parts from said parent bar thereby enabling said sliding parts to slide along said parent bar and said tricycle to be folded into a position where said front wheel is positioned in between said first and second rear wheels. ### Claim 12 (depends on 1) The folding tricycle of claim 1, further comprising two rear supports, each fixed relative to its respective rear frame; each rear support intended to limit the movement of its respective bottom frame. ### Claim 13 (depends on 1) The folding tricycle of claim 1, further comprising a front support configured to limit the movement of said front frame relative to said seat frame and to fixate the angles between said first and second bottom frames and said front frame; and between said front frame and said seat frame thus creating a stable tricycle structure in said unfolded position. ### Claim 14 (depends on 11) A method of folding a folding tricycle, comprising: a. providing the folding tricycle of claim 11; b. unlocking said locking mechanism thereby releasing said sliding parts from said parent bar and enabling said sliding parts to slide along said parent bar; c. sliding said sliding parts upwards along said parent bar up to a point where the angle between said first and second bottom frames and said front frame passes an over-center position; and d. sliding said sliding parts downward along said parent bar. ### Claim 15 A folding tricycle, comprising: a first rear frame rotatably connected on a first end thereof with a first end of a first bottom frame; a second rear frame rotatably connected on a first end thereof with a first end of a second bottom frame; said first rear frame rotatably connected on a second end thereof with a first rear wheel; said second rear frame rotatably connected on a second end thereof with a second rear wheel;

wherein said tricycle is configured to be folded into a position where said front wheel is positioned in between said first and second rear wheels. ### Claim 16 (depends on 15) The folding tricycle of claim 15, further comprising first and second anchors; said first and second anchors fixed respectively relative to said first and second support frames; said first rear frame, said first support frame, said first anchor and said first bottom frame are connected to each other on first ends thereof thereby creating a first folding mechanism; said second rear frame, said second support frame, said second anchor and said second bottom frame are connected to each other on first ends thereof thereby creating a second folding mechanism; said first and second support frames are connected on second ends thereof with said locking mechanism; each one of said first and second folding mechanisms is configured to: (a) position its bottom frame in a fixed position relative to its rear frame when said locking mechanism secures said locking frame to one of a rear end of said seat frame, and a seat connected with said seat frame; and (b) enable its bottom frame to move when said locking frame is detached from said rear end of said seat frame or said seat, and its respective anchor and locking frame touch the ground. ### Claim 17 (depends on 16) The folding tricycle of claim 16, wherein said first and second folding mechanisms are further configured to enable folding of said first and second rear wheels towards each other in order to minimize the overall dimensions of said tricycle. ### Claim 18 (depends on 16) The folding tricycle of claim 16, further comprising: a wheel fork connected between said front wheel and said handlebar, said wheel fork is connected with said handlebar through said one of said front frame and said front bearing member. ### Claim 19 (depends on 15) The folding tricycle of claim 15, wherein said handlebar is telescopic. ### Claim 20 (depends on 15) The folding tricycle of claim 15, further comprising two safety bars connected with said seat frame. ### Claim 21 (depends on 15) The folding tricycle of claim 15, further comprising at least one telescopic bar connected with one of said seat frame and a seat. ### Claim 22 (depends on 21) The folding tricycle of claim 21, further comprising a handle connected with said at least one telescopic bar. ### Claim 23 (depends on 21) The folding tricycle of claim 21, further comprising a canopy connected with said at least one telescopic bar.
