The split axle wheel system may include a wheel having a first side and a second side. The first side and the second side may each include a rim. A spoke array and a drive ring gear may be attached to the rim. A chain may be wrapped around the driving ring gear, which is connected to a motor to rotate the wheel. The spoke array may include an opening with a bearing inside of the opening. A split axle bracket may run through the bearing and through the drive ring gear and may attach to the swing arm assembly of the motorcycle. ## Claims ### Claim 1 A split axle cycle wheel assembly comprising: a wheel comprising a first side and a second side, wherein the first side and the second side each comprise a rim; a spoke array mounted to the rim, wherein the spoke array comprises a center portion forming an opening; and a bearing within the opening of the spoke array; a drive ring gear mounted to at least one of the first side and second side of the wheel; a pair of split axle brackets each comprising a first end and a second end, wherein each split axle bracket runs through the bearing of the first side and the second side of the wheel; and a swing arm assembly configured to attach the wheel to a cycle, wherein the swing arm assembly comprises a first arm and a second arm each attached to the second ends of the pair of split axle brackets. ### Claim 2 (depends on 1) The split axle cycle wheel assembly of claim 1, further comprising a brake system comprising: a brake rotor attached to the brake rotor; a brake caliper, wherein the first end of the split axle bracket is attached to the brake caliper; and a brake line running from the brake caliper to a brake master cylinder of the cycle. ### Claim 3 (depends on 1) The split axle cycle wheel assembly of claim 1, wherein the second end of the pair split axles comprise a splined shoulder and a threaded end, and the first arm and the second arm comprise a splined opening, wherein the splined shoulder fits through the splined opening, and a threaded nut is screwed to the threaded end, thereby connecting the swing arm assembly to the split axle. ### Claim 4 (depends on 1) The split axle cycle wheel assembly of claim 1, wherein the spoke array comprises the center portion and an outer portion, wherein the outer portion comprises a plurality slots, wherein the rim comprises a plurality of cleats that align with the slots and wherein the spoke array is removably attachable to the rim by fitting the plurality of slots within the plurality of cleats and using a plurality of screws to screw the spoke array to the rim. ### Claim 5 (depends on 1) The split axle cycle wheel assembly of claim 1, wherein the spoke array comprises a plurality of arms comprising threaded openings, wherein the drive ring gear is attached to the spoke array by screws running through openings in the drive ring gear and screwing into the threaded openings. ### Claim 6 A split axle cycle wheel assembly comprising: a wheel comprising a first side and a second side, wherein the first side and the second side each comprise: a rim comprising an outer portion and an inner portion; a brake rotor; a brake caliper; a spoke array mounted to the rim and the brake rotor, wherein the spoke array comprises a center portion forming an opening; and a bearing within the opening of the spoke array; a drive ring gear mounted to at least one of the spoke arrays on the first side and the second side of the wheel; and a first split axle bracket and a second split axle bracket each comprising a first end and a second end, wherein each of the first ends is attached to the brake caliper on the first side and the second side of the wheel and each of the second ends runs through the bearing on the first side and the second side of the wheel. ### Claim 7 (depends on 6) The split axle cycle wheel assembly of claim 6, further comprising a cycle comprising a swing arm assembly comprising a first arm and a second arm, wherein the split axle bracket on the first side attaches to the first arm and the split axle bracket on the second side attaches to the second arm. ### Claim 8 (depends on 7) The split axle cycle wheel assembly of claim 7, wherein the second end of the split axle comprises a splined shoulder and a threaded end, and the first swing arm and the second swing arm comprise a splined opening, wherein the splined shoulder fits through the splined opening, and a threaded nut is screwed to the threaded end, thereby connecting the swing arm assembly to the split axle. ### Claim 9 (depends on 7) The split axle cycle wheel assembly of claim 7, wherein the spoke array comprises the center portion and an outer portion, wherein the outer portion comprises a plurality slots, wherein the rim comprises a plurality of cleats that align with the slots and wherein the spoke array is removably attachable to the rim by fitting the plurality of slots within the plurality of cleats and using a plurality of screws to screw the spoke array to the rim. ### Claim 10 (depends on 7) The split axle cycle wheel assembly of claim 7, wherein the spoke array comprises a plurality of arms comprising threaded openings, wherein the drive ring gear is attached to the spoke array by screws running through openings in the drive ring gear and screwing into the threaded openings.
