The Cosmic 29 TROY 21 Speed is positioned as a value-friendly 29-inch wheel MTB/fitness bike that gives you the big-wheel feel, full gearing, suspension and disc brakes — without breaking the budget.
“Designed for versatile riders who want one bike for city, rough roads and leisure rides.”
In this review we’ll explore frame, drivetrain, comfort, brakes & steering, wheels & saddle, then wrap up with a verdict and pricing/availability insights.
The steel hard-tail frame is a solid foundation. Steel adds weight compared to premium alloys, but it gives durability and often more forgiving flex over rough surfaces. With 29″ wheels, the rollover benefits are real: you’ll feel less prone to small bumps or uneven patches. For riders of average height (~5’6″ to 6’0″) this can be a comfortable fit; those much taller or shorter should check effective reach and stand-over clearance.
In use, the bike felt stable: the large wheels and sizeable frame gave a planted feel. While the suspension front helps, being a steel hard-tail means it will not absorb everything like a full-suspension bike—but that’s not its purpose. The design prioritises value and usability over ultra-light racing.

A 29-inch hard-tail with disc brakes and full gears — very few bikes in this price bucket do all three
The 21-speed (3×7) gearing offers decent flexibility. For varied terrain – from city roads to moderate climbs – the gear spread works. The components (Microshift/shim-tourist level) may not offer race-level precision, but for everyday riding they perform well.
In practical ride-testing, shifting was smooth for normal loads; heavier climbing or sudden terrain changes required conscious shifts and attitude—but that’s expected at this class.

With 21 gears you feel prepared, not overwhelmed
Comfort is favourable for its category. The front suspension fork helps soften bumps; the large 29″ wheels smooth out road chatter and small obstacles. The upright-ish geometry (as common in bikes of this type) keeps you more relaxed rather than aggressive.
The saddle and contact points are decent for moderate rides; for very long rides you might want to upgrade the saddle or grips. The bike handles rougher patches better than many narrow-wheel road bikes.

Ride longer, ride smoother — thanks to the 29″ rollover and suspension front
Dual disc brakes (front + rear) are a strong feature in this segment. Compared to rim brakes or V-brakes, discs give better stopping power, reliability in wet/dusty conditions and improved modulation. That’s a real plus in diverse riding conditions (Indian urban + semi-rough roads).
Steering is stable thanks to the 29″ wheels and geometry tuned for control rather than twitchy race feel. The fork suspension also helps keep the front wheel planted over rough surfaces.

Disc brakes plus stable steering mean more control on every descent, turn or surprise surface
The 29-inch wheels are among the standout specs. They give you advantage in rollover, momentum, and stability. The tyres (~2.40″ width) are wide enough to offer good grip but not so wide as to penalise on-road speed significantly.
Rims and hubs appear aimed at durability rather than premium weight savings, which is appropriate for this price. The saddle is basic but serviceable; if you do long rides you may consider upgrading it later. Tyre pressure, saddle angle and handlebar position will all influence ride experience—worth spending some time tuning.

Large wheels + wide tyres = more confidence on mixed surfaces
Overall, the Cosmic 29 TROY 21 Speed is a very good value proposition for riders looking for a one-bike solution that covers commuting, fitness rides and occasional rough roads/trails. It offers big wheels, full gears, front suspension and disc brakes—features many budget bikes skip.
