The Firefox Firestorm 27.5D is positioned as a hard-tail mountain bike aimed at riders who want a capable trail/fitness bike that can handle urban roads, light trails, fly-overs and mixed surfaces. Its design spans from everyday commuter paths to casual trail rides.
“This bike is built to bring off-road capability into city-and-trail use—ready for real world mixed surfaces.”
In this review I’ll cover the frame/fit/design, drivetrain/performance, comfort, brakes & steering, wheels & saddle, and complete with a verdict (and pricing for the Indian market).
The Firestorm 27.5D uses an alloy hard-tail frame—solid in build, giving a good mix of rigidity and durability for the price. According to specs the frame is described as “Alloy Hardtail” with a geometry aimed at comfort rather than racing.
The geometry offers a more upright posture than aggressive trail bikes, which helps for mixed use (commute + trail). The suspension fork adds to usability over rougher roads. Fit-wise the 27.5″ wheel size means it can suit a range of rider heights (typically medium frame sizes).

Built to handle both city corners and light trail lines—with an alloy frame that balances control and durability
With a 3×8 (24-speed) set-up, the Firestorm 27.5D gives a wide gearing range which is advantageous for climbing, accelerating on flats, and maintaining momentum. For example, the freewheel spec lists 12-32T steel in some sources.
In practical riding, shifting felt reliable, the Microshift derailleurs performed without major lag, and the gear spread gave one flexibility for moderate uphill efforts as well as faster flats. The 3-ring front (e.g., 24/34/42T in one spec) helps with low-gear ease

In the real-world ride, the drivetrain keeps up in varied terrain—climbs, flats, trails—with enough flexibility for most casual or intermediate riders
Comfort is a strong point here: the suspension fork (though moderate travel) smooths out rough roads/trail lumps; the 27.5″ wheels give good rollover and stability; and the geometry provides a comfortable ride posture.
Because the bike is built for mixed terrain rather than race posture, you’ll get a more relaxed ride feel: less forward lean, easier handling, and confidence on uneven surfaces. The seat and grips are industry-standard—adequate but not top-tier premium.

If your ride mixes city roads and trail segments, the Firestorm delivers a comfortable, responsive ride rather than a harsh race feel
The mechanical disc brakes give a meaningful upgrade over rim brake setups: better wet-condition behaviour, improved modulation, and more control on descents. The spec lists JAK 7 mechanical disc brakes in some sources.
Steering is precise enough for trail usage; the harder tail, decent frame and appropriate fork mean the bike corners well and holds its line. The upright geometry helps in traffic or commuter scenarios as well.

Confident braking and controlled steering make this bike ready for mixed surfaces and unpredictable urban/trail conditions
The 27.5″ wheels (double-wall alloy rims, 36H in some spec sheets) provide good strength and durability. The tyres (~2.0″ width) strike a balance between trail grip and urban roll. One spec mentions Kenda tyres sized 27.5″ × 2″.
The saddle is typical for this segment—comfortable for moderate distance rides, but riders who extend to longer trail adventures might choose to upgrade to a more ergonomic saddle.

Solid wheel/tyre combo plus a comfort-oriented saddle to support both city commuting and occasional trail fun.
Overall, the Firefox Firestorm 27.5D is a compelling option for riders looking for a versatile hard-tail MTB that covers both urban and light trail use, without heavy premium cost. It balances durability, component spread and ride comfort for everyday fitness and moderate adventure.
