Scooter handlebar engineered to balance low weight with practical strength for custom builds. Ideal for riders who assemble or modify scooters, seeking responsive control and neat aesthetics. Is the Envyscooters BLUNT Union Bar the right choice for a lightweight, build-focused setup?

⚡ At a Glance
  • Build Quality: Dimensions 650mm H x 600mm W, backsweep 3, weight 900g, designed for common compression systems
  • Best for: Scooter builders and riders wanting a lightweight bar that makes a build more responsive
  • Not ideal for: Riders lacking an oversized 34.9mm clamp or an SCS adaptor, as these are required for some fits

650mm by 600mm dimensions and a 900g mass give a light, roomy stance. Compatible with ICS or IHC compression, SCS use requires a Blunt SCS Adaptor which is not included.


Light, nimble handling - thanks to the 900g weight

A listed weight of 900g keeps rotating mass lower than heavier bars, so overall scooter mass remains modest. Lower mass around the bars helps quicker initiation of spins and easier flicks during tricks.

Easier manoeuvres and less fatigue when carrying or jumping, making the bar a sensible choice for riders focused on tricks and frequent use.

Comfortable control and stance - with 650mm by 600mm dimensions and 3 backsweep

Height and width of 650mm H x 600mm W combine with a backsweep value of 3 to set hand position and leverage. The geometry encourages a balanced, slightly upright grip suited to stability and precise steering.

Improved balance on landings and steadier control during grinds, useful for riders who prefer a roomy bar for leverage and comfort.

Flexible build compatibility - with ICS or IHC compression, SCS possible via adaptor

Designed for ICS or IHC compression systems, while SCS can be used when fitted with a Blunt SCS Adaptor that is sold separately. The bar requires an oversized clamp of 34.9mm for proper secure installation.

Simplifies integration into most custom builds while signalling the need to check clamp size and adaptor availability before assembly.
