Escape Collective
In for review: Polygon Helios A – Is this a budget-friendly do-it-all race bike?

mai 2025 · Alex Hunt

Polygon’s Helios A undercuts the big brands and claims to offer all-round race performance. Can it deliver on both price and ride?

Points forts

  • Undercuts big brands on price

  • 34 mm tyre clearance for versatility

  • Ability to swap between proprietary aero seatpost and standard 27.2 mm round post

  • Potential for greater compliance and comfort with round seatpost

Points faibles

  • Brand seemingly unsure how to define the bike (race or endurance)

  • Frame geometry remains fixed, limiting transformation into a true endurance bike
