Three-wheelers are experiencing dullness as commuters are reluctant to hire them, claim sources. They mention that this is adding to the difficulties of three-wheeler operators who have seen their business ilde almost for the two months of April and May. While companies like Bajaj Auto have upgraded their three-wheeler range to BSVI, the dull business prospect of the segment, at least in the short-term, is likely to pull down the grades, state sources. They draw attention to the cautious approach of the lenders as well, as they face the grim prospect of a good number of their existing loans turning into NPAs. The sources also point at the SIAM data for FY 2019-20, which has shown a nine-per cent fall in domestic volumes of three-wheelers amounting to 6.36 lakh units roughly. They, in addition, stress on the lesser availability of permits and a steep price increase because of BSVI too.
