HAVANA (AP):Cuba’s iconic vintage cars have all but disappeared and, in their place, small electric tricycles, most of them made in China, have become the primary means of transportation for hundreds of thousands of Cubans grappling with a prolonged fuel crisis.These are no ordinary electric tricycles, many Cubans have outfitted them with solar panels, allowing the vehicles to recharge without relying on the island nation’s strained power grid.The three-wheelers are a far cry from the old-timers that only a year ago cruised the streets spewing clouds of black smoke.“This is how people get around now,” said 40-year-old Liecer de la Cruz, who owns one of these vehicles.The tricycles, with a cost between US$2,000 and US$4,000, are used to transport goods and serve fixed routes once covered by buses.While their price is out of reach for most Cubans, many have sold their older gasoline-powered cars to buy the tricycles. Others got them from relatives abroad, where they are generally cheaper, and some small-business owners even used their profits to invest in them, expecting to recoup the cost.In January, US President Donald Trump threatened to impose tariffs on countries that sell oil to Cuba, which produces only about 40 per cent of the fuel it needs. Since then, just a single oil tanker has arrived on the island, in late March, down from about eight a month previously.The impact on daily life in Cuba has been significant.Rolling blackouts have worsened, exacerbating hardships in a country whose economy has been in crisis for five years. Shortages of food and medicine have deepened, and public transportation has been sharply reduced.Amid the crisis, electric tricycles have become indispensable. They transport goods, serve fixed routes once covered by buses and, in some Havana neighbourhoods, they are used to collect garbage.People with heavy shopping bags can catch rides on the tricycles –  a slow, hot and uncomfortable ride. But it’s better than walking.“If you can pay for it, you just take it; otherwise, you can’t go anywhere,” said Berta Ferrer, a 52-year-old clerk at a store in central Havana where she works four days a week.She pays about CU$500 – less than US$1 – for the ride, a significant expense in a country where monthly salaries average about US$10 for state workers and roughly US$40 for private-sector employees.Electric tricycles from Chinese brands such as Zonsen and Jinpeng have become a common sight on Cuba’s streets. Many are bought in countries such as Panama and shipped to the island by relatives or importers for resale, and they run on gel or lithium batteries. Under an agreement with China, the Vedca brand is assembled in Cuba.Some owners have installed solar panels on the awnings over seats of the tricycle, allowing them to recharge on the go and keep operating despite the island’s energy crisis.“There are so many tricycles in Havana that you can’t spend 10 minutes on a street without seeing countless numbers of them pass by,” said 29-year-old engineer Carlos Álvarez, who owns a workshop specialising in electric vehicles.He spoke as he was installing a mounting bracket for a solar panel on one of the tricycles and acknowledged the investment can be costly – about US$500 – but said it pays off quickly as it helps owners cope with fuel shortages and blackouts.Ricardo Quintero, an engineer who owns one of the tricycles, said he uses it to transport produce to the vegetable stand he runs with his family.“I think this is here to stay,” he said, looking at his three-wheeler.
