Hello, Every one I'm Bharat. Today here I've done a futuristic, innovative model bike which major machinery of the bike lies inside of one large wheel , Of course a small wheel at back which support the bike at rest and for other purpose also.

This O-Byke actually runs on two wheel frames which are parallel to each other ( the black one's are wheels and middle center white one is engine. When a person sits on this bike, it calculates the height adjustment needed by the rider's body and automatically adjusts the foot rest position and seat adjustment towards handle .So, that any a person can ride this bike irrespective of rider's height , height ranging from 4'5 feet - 7'0 feet.

Due to single large wheel with wide base ,it gains more stability and balance and even the bike can stand on its own balance with out any stand or support (even when rider is on o-byke )and this balance is mainly due to two wheel frames which are parallel to each other and as the weight of engine is more when compared to rider so that bike has more stable. Now coming to the rear small wheel, its main functionality is to support bike when short height person needed get on to the bike this bike , it automatically tilt the bike about 40-45 degrees , so that rider can get on bike irrespective to height.

It took nearly 8 hours to design this bike and to get an appropriate shape.Here is the tutorial of this O-Byke , while designing this I've changed shape of many object from time to time, to get an appropriate shape. So ,I request viewers please don't get confused about the design while watching the tutorial and also please maintain patience.

Step 1:

Step-1

1)First create a cylinder of large radius and short length such that it looks like a wheel.
Note:this center wheel stands as engine chamber which is situated in between two tire frames .

2)Now create an another cylinder, such that the engine chamber touches it on the circular face and its radius should be larger that the above drawn cylinder.Then just copy, paste this on other side of circular face (or) draw another cylinder with same measurements.

Step 2:

Step-2

1)Now apply Chamfer effect to outer circular edges of two tire frames( two similar cylindrical shapes ).

2)Then again create a cylinder of very narrow length and smaller radius compared to outer tire frame,this is done both the circular faces on opposite sides as shown in figure.

3)Repeat the construction of similar above cylindrical shaped object but with more length and less radius that above case.

Step 3:

Step-3)

Now, its time for creating support to side suspension looking things and upper body.

1) Just create a rectangle( cuboid) such that its length must be from the center of those cylinders to up above the wheel frame ( see the picture) . Create these rectangles on both sides.

2) Then place a cuboid above those two side suspension frames, which joins them( see the picture ).

Step 4:

Step 4)

1) Now create a cuboid as shown and slightly tilt it about 30".

2)Apply fillet effect to those slanted edges.

3)Add another only one cuboid.

Step 5:

Step 5)

1)Place a cuboid at the front part .

2) Apply fillet to both the edges of side suspensions.

3)Now , I've slightly risen the height of that tank shaped part, so that to apply a fillet effect to a curved edge, this gives a nice finishing work and very appealing look .

Step 6:

Step 6)

Now , It's time to create a Handle to O-Byke.

1) Create a cylindrical base as shown and then place a cuboid.

2)Now elongate the cuboid sidewards, then both the surfaces of cuboid which are towards both the wheels are tweaked(slanted) to about 30" .

3) Now to those slanted surfaces, add cylinders such that they act as handles to O-Byke.

4)Select the upper surface to make it slanted as shown.

5)Place a cuboid on that slanted surface , Now apply fillet effect to the both front facing edges, As this gives a nice curvy speedometer.

6)Now apply a fillet effect to both upper and lower circles of Handle base cylinder [ which was created in Point-(1) ].

7)Just go to the front part of bike ( *see last pic of this step).In previous step ,I've said to create that cuboid ,Just click on upper edge and then tweak it as you like .
