When Karachi-based Bykea launched in 2016, the bike-taxi model was a whole new concept for Pakistan. Today, the company has 60,000 drivers, with more than 1.7 million monthly active users on its app. Affordability has played a critical role in popularizing bike-taxis as a mode of transportation in the country, according to Rafiq Malik, Bykea’s chief operating officer. He said that while e-scooters are useful for making deliveries, they are not apt to ferry passengers.
