EMotorad T-Rex Air
The EMotorad T-Rex Air is a hardtail mountain e-cycle for city commutes and light trail riding, priced from Rs 36,999, built around a throttle you can twist for instant power plus genuine 5-level pedal-assist, with EMotorad's claimed range going up to 65 km on a charge. It's aimed at riders who want the option to switch between full electric assist and honest pedalling on the same bike, not racers chasing outright speed or anyone shopping for the lightest possible frame.
Is the EMotorad T-Rex Air right for you?
Best for
- Daily commutes of roughly 15-25km round trip, where the 65km claimed figure leaves real-world cushion even after typical dropoff
- Riders who want a working throttle for traffic and stop-start riding, with 7-speed pedal-assist as a backup once the battery runs down
- Mixed tarmac-and-broken-road routes, thanks to front suspension and MTB-pattern tyres on both wheel sizes
- Buyers who want a large, removable 468Wh battery they can pull out and charge at a desk or in an apartment without a dedicated charging point
Think twice if
- Anyone wanting the lightest e-cycle to carry up stairs or onto a train - the high-tensile steel frame puts this near 22kg, heavier than aluminium rivals in its class
- Riders who need hydraulic disc brakes for hard technical trail use - the T-Rex Air uses mechanical (cable-actuated) discs
- Buyers planning serious off-road jumps or technical single-track - it's a hardtail with front-only suspension, meant for light trail and street, not aggressive MTB riding
- Anyone assuming this is automatically paperwork-free - a working throttle plus a 300W motor takes it past the 250W pedal-assist-only threshold that's clearly exempt from RTO rules, so this needs local confirmation, not an assumption

Variants, specs, on-road price and running cost
A pedal-assist e-cycle up to 250W and 25 km/h needs no RTO registration, road tax, licence or insurance in India, so the on-road price is the ex-showroom price. Throttle or higher-power models may need registration - check the variant spec.

Charging and living with it
Charging times vary by variant and charger; see each variant above. Most owners charge at home from a standard socket, and many packs are removable so you can carry the battery indoors to charge. The T-Rex Air pairs a working throttle with a 300W motor, above the 250W pedal-assist-only threshold that's clearly exempt from RTO registration, licence, and insurance in India. Confirm the current registration position with your local RTO before buying, particularly if you intend to ride mostly on throttle rather than pedal-assist.
Strengths
- Confirmed throttle plus 5-level pedal-assist, usable as a pure e-bike or a geared cycle
- Large 468Wh (36V 13Ah) removable battery with strong claimed range (up to ~65km PAS)
- 7-speed Shimano Tourney gearing
- Competitive price around Rs 36,999-37,499
Watch-outs
- High-tensile steel frame makes it heavier (~22kg) than aluminium siblings
- Mechanical (not hydraulic) disc brakes
- Basic hardtail with front-only suspension

FAQ
What's the real-world range on the T-Rex Air, not the claimed figure?
The 65km number is EMotorad's own claimed figure, almost certainly recorded in the lowest pedal-assist level, on flat road, with a light rider and no cargo. There's no independent real-world test figure published for this model. Ride on throttle, use higher assist levels, climb hills, or carry weight, and expect meaningfully less - plan around less than half that figure if you'll lean on the throttle often.
Is the T-Rex Air pedal-assist only, or does it have a throttle?
Both. It ships with a working throttle for power on demand without pedalling, plus 5 levels of pedal-assist, so you can ride it as a proper electric bike in traffic or as a geared cycle with an electric boost when you want to pedal.
Do I need registration, a licence, or insurance to ride this?
This is the one thing to check locally rather than assume. A pedal-assist-only e-cycle at 250W or under is exempt from RTO registration, licence, and insurance in India. The T-Rex Air's 300W motor and functioning throttle push it past that clean exemption in a strict reading of the rules, so confirm the current position with your local RTO before you buy, especially if you plan to ride mostly on throttle.
How long does it take to charge, and what does that cost?
EMotorad hasn't published an official charge time for this 468Wh (36V, 13Ah) pack, so it's safest to plan on charging it overnight rather than assume a quick top-up. Whatever the exact time, the running cost is trivial - a full charge draws a small fraction of a household electricity unit, so it costs only a few rupees.
Which variant should I buy - the 27.5-inch or the 29-inch wheel version?
Both use the same 468Wh battery, 300W motor, and 7-speed drivetrain, and sit only Rs 500 apart in price. The 27.5-inch wheel feels a touch more agile for tight city riding; the 29-inch wheel rolls over broken road and gravel more smoothly and tends to suit taller riders better. Choose by your height and where you'll mostly ride, not by spec sheet.
