In a move that could reshape India’s two-wheeler landscape, Sun Mobility has launched a nationwide initiative to convert aging internal combustion engine (ICE) scooters into battery-electric vehicles (EVs) — offering a cost-effective, scalable, and sustainable solution to India’s urban mobility challenge.
🔧 Turning Old into Gold: The Retrofit Revolution
Dubbed as a “second life” for scooters, this retrofit program targets the over 200 million ICE scooters currently plying Indian roads. For approximately ₹30,000 per vehicle, Sun Mobility will replace the petrol engine with an electric drivetrain compatible with its innovative battery swapping network.
Rather than scrapping old scooters or spending on new EVs, owners — particularly fleet operators — now have a compelling middle path: revive, retrofit, and recharge.
“This is not just about technology — it’s about inclusivity and speed. Retrofitting is the fastest way to bring millions into the electric mobility fold,” said a Sun Mobility spokesperson.
🔋 Battery Swapping Makes It Seamless
What truly sets Sun Mobility’s offering apart is its integration with a countrywide battery swapping infrastructure. With over 600 swap stations in 22 cities, retrofitted scooters can now replace drained batteries in under a minute — eliminating the need for at-home charging or range anxiety.
This plug-and-play ecosystem not only reduces vehicle downtime but also brings down monthly operational costs by up to 40%, a major advantage for delivery fleets, logistics providers, and shared mobility services.
🌍 Going Global: Kenya, Southeast Asia Next
While India is the primary focus, Sun Mobility is eyeing global markets too. The retrofit program is slated to debut in Kenya, with plans to expand into Southeast Asia, where ICE two-wheelers dominate the streets and electrification is still nascent.
This global play is backed by solid funding. The company recently raised \$57 million from Helios Climate, a fund focused on climate solutions. State-owned Indian Oil Corporation is also a key investor and collaborator in the swapping infrastructure.
📦 Commercial First: Fleets Drive the Shift
Sun Mobility’s retrofit solution is being positioned primarily for business and fleet use, not individual consumers — at least initially. This includes:
- Food and e-commerce delivery companies
- Logistics operators using two-wheelers
- Aggregators and ride-hailing startups
These groups stand to benefit the most from lower fuel and maintenance costs, easier compliance with urban EV mandates, and reduced emissions footprints.
🛠️ Beyond Scooters: Commercial Vehicles Too
The retrofit model isn’t stopping with two-wheelers. In collaboration with Bluwheelz, Sun Mobility is also converting Tata ACE light commercial vehicles to electric — enabling swappable batteries and significant savings for small businesses.
♻️ Why Retrofitting Matters
Retrofitting ICE vehicles offers three key benefits:
- Affordability – No need to buy new EVs when old ones can be revived.
- Sustainability – Cuts manufacturing emissions and delays scrappage.
- Speed – Fastest way to scale electric mobility under new regulatory pushes.
Delhi and other Indian states are increasingly enforcing ICE bans for last-mile delivery. Retrofitting provides an immediate compliance pathway.
