There are Two Wheelers, Three Wheelers and Four Wheelers running on the Road.

What i observe in Two Wheelers i.e Bikes is there is no storage mechanism
for keeping extra Tyre/s which can be useful to the Driver in case there
is a tyre puncture while traveling on the road.

In Two wheelers Scooters, the Tyre has a smaller circle radius,the extra Tyre
in a Scooter is fixed behind the rear Tyre seat.

In three Wheelers Auto rickshaws the extra Tyre is kept near engine placement
i.e rear/back door

In four Wheelers viz cars, jeeps the extra Tyre and fixing tools can be kept in the storage mechanism i.e rear door.

In four Wheelers heavy vehicles viz Buses, Trucks, Lorries etc the extra Tyre can be kept down below fixed.

Is there any way to Keep a Storage mechanism for Bikes two wheelers ?. What could be the design for the same if it is to be achieved ? can we keep the Tyre below the seat where the driver is seating ?

Note : Observed that the Tyres for each of the two, three and four wheeler vehicles is a circle and has a Different Radius and circumference.

Thanks & Regards,
