The biggest complaint about the TVS Jupiter CNG is that it has a reduced storage capacity because of the CNG tank. Partly because they're practical and can carry groceries, bags and other items, scooters are popular in India. A major drawback for many users will be the Jupiter CNG's underseat storage, which is much smaller than its petrol counterpart. This has led to debates as to whether fuel cost savings and environmental benefits trump the loss of convenience. Some say the dual fuel option circumvents this, others say that it’s a fundamental flaw in the design. It also discusses how this might affect different user groups from daily commuters to delivery personnel.
