All three Heist models use Polygon’s AL6 aluminium frame, which balances weight, strength and cost. Hydroforming and butting techniques allow aluminium to rival carbon for stiffness and ride quality at a lower price[1]. The frame has an upright geometry with a comfortable reach and stable steering – ideal for city streets and bike paths. Mounts for racks, fenders and bottle cages make the bikes ready for commuting and touring.

The Heist X2 comes with a basic coil-sprung suspension fork (about 63 mm travel) and a 3×8 drivetrain. This setup offers a wide range of gears for tackling hills, but the coil fork is heavier and less adjustable. Braking is handled by mechanical disc brakes. Stepping up to the X5 brings an air-sprung fork with more adjustability and a 3×9 drivetrain, along with hydraulic disc brakes that provide stronger, more modulated braking[3]. The X7 tops the line with an SR Suntour NCX or equivalent air fork, a 1×11 Shimano Deore drivetrain and powerful hydraulic brakes. Its wider 45 mm tyres and tubeless-ready wheels make it more capable on gravel and light trails.

On urban streets and bike paths, the Heist X2 feels lively and efficient. The coil fork smooths out potholes, but it adds weight and can bob when climbing. The wide gear range makes it easy to spin up hills. The X5’s air fork feels noticeably smoother and lighter, and the hydraulic brakes inspire more confidence in traffic. I found the extra gears on the 3×9 drivetrain useful when hauling groceries or riding hilly routes. The X7 is the most polished: the single-ring drivetrain simplifies shifting, the fork soaks up bumps and the hydraulic brakes stop with ease. Despite its upgrades, the X7 remains affordable thanks to Polygon’s direct-to-consumer pricing[2].

Choose the Heist X2 if you’re new to cycling or on a tight budget and want a versatile bike for commutes and errands. The X5 is ideal for riders seeking a smoother fork and better braking without a big price jump. If you plan to explore unpaved paths or want the best performance, the X7’s 1×11 drivetrain and premium suspension are worth the investment. No matter which model you choose, you’ll get a durable hybrid with mounts for accessories and room for future upgrades.

The Polygon Heist X2, X5 and X7 prove that hybrid bikes can be tough, versatile and great value. By sharing a quality aluminium frame and scaling components to suit different budgets, Polygon offers options for everyone from casual commuters to adventure-ready riders. Thanks to direct-to-consumer pricing, these bikes deliver features normally found on more expensive hybrids, making them some of the best urban bikes for the money.
