The problem

Fuel costs eat your day.
Pure EVs cost you range.

Petrol and CNG prices don't move in your favor. Pure electric autos solve running cost but create a new problem - limited range, long charging waits, and a whole new vehicle to finance. Retrofyx doesn't ask you to choose. Your engine stays exactly where it is - run electric in the city, switch to fuel whenever you need to go further.

Pilot program

A limited early-access pilot

1 of 2 slots open

We're running a small early-access pilot to validate performance in real conditions before opening Retrofyx to more drivers. This is a limited pilot, not a general public offer.

Where we are today

  • Kit is undergoing internal road testing with logged performance data.
  • We're working through the regulatory approval process required for road use.
  • Pilot vehicles are tested in a mix of controlled and real-world conditions.

What early access means

  • Direct input into the product as we build it.
  • Priority consideration for future units and cohorts.
  • A committed partner on our side through the pilot period.
Apply

Apply for early access

Takes two minutes. We'll reach out if your vehicle is a fit for the current pilot phase.

Only Bajaj RE, BS4 (2014–2018) is supported right now. Other models are welcome to apply for the waitlist.

This form is a draft - connect it to your inbox, CRM, or Google Sheet before launch.

About Retrofyx

Built for the millions of autos already on the road

Retrofyx Mobility is an electric hybrid retrofit company based in Bangalore, Karnataka. We build kits that convert existing petrol and LPG/CNG auto-rickshaws into electric hybrids - without removing the engine you already rely on.

Pure EVs ask a driver to give up something real: range beyond the battery, the ability to keep working when charging infrastructure isn't there, and a vehicle he already owns outright. Our kit keeps the existing engine in place and adds an electric motor alongside it, giving three usable power sources - Electric, Petrol, and LPG/CNG - instead of forcing a choice. Fitment takes under 60 minutes, and any regular roadside mechanic can service the vehicle afterward.

Our first working prototype was built and tested within two months of starting. We've filed a patent application and registered the Retrofyx trademark. Retrofyx was founded by engineers and industry veterans with a combined background in EV hybrid retrofitting, electrical and electronics engineering, and vehicle systems design.

Millions of petrol and LPG/CNG autos are already on the road. We think converting them is faster, more affordable, and more practical than waiting for a full fleet replacement most drivers can't currently finance.

FAQ

Questions drivers actually ask

Is this legal to drive after fitment?

We're working through the regulatory approval process required for road use as part of this pilot phase. We'll be upfront with pilot partners about status at every step - this isn't a general public offer yet.

What happens to my vehicle during the fitment?

Fitment takes under 60 minutes. The electric hybrid system is added alongside your existing engine - the engine itself isn't removed or replaced.

What if my auto isn't a Bajaj RE, BS4 (2014–2018)?

Apply anyway and select the waitlist option. Additional models and manufacturers are planned after this pilot.

How long does the battery last per day?

70+70 km range per swap, across two 3.36 kWh battery packs. Actual range depends on drive mode, load, and terrain.

What's the actual cost?

₹50,000 for the kit, on-road, inclusive of GST, battery not included. See the pricing section above for the two battery ownership options and their true cost over time.

If I'm not selected for the pilot, what happens?

Nothing is taken from you by applying - you'll be added to the waitlist for the next cohort as we expand beyond the current 2-unit pilot.
