Stacyc EXTENDED SEAT POST - 185MM 18/20eDrive

Give growing riders more room and comfort with the STACYC Extended Seat Post (185mm), designed specifically for 18eDRIVE and 20eDRIVE models. This longer seat post raises the riding position, making it ideal for taller kids or those transitioning between bike sizes.

Compared to the stock seat posts (120mm on 18eDRIVE and 135mm on 20eDRIVE), the 185mm length provides a noticeable increase in seat height—helping extend the usability of the bike as riders grow.

Built to OEM specifications, it offers a direct-fit installation and maintains the same durability and secure clamping system as the original component.

Key Features:

• Fits STACYC 18eDRIVE and 20eDRIVE models
• Extended 185mm length for taller riders
• Improves comfort and riding position
• OEM replacement for precise fit and easy install
• Ideal for growing riders needing extra seat height
