DK Helio Frame

Product Overview

The DK Helio is a street and park BMX frame built with responsive geometry for technical riding. Featuring a 21" top tube and 13.6" rear center, this frame balances quick maneuverability with stability for transitions and street obstacles. The 11.9" bottom bracket height and steep angles (75° head tube, 72° seat tube) provide low center of gravity and agile handling. Accommodates up to a 26-tooth sprocket.

Key Features

• 21" top tube – Standard length suits riders approximately 5'7" to 6'0" or those who prefer balanced positioning between compact and stretched-out feel
• 13.6" rear center – Short chainstay length increases back-end responsiveness for quick manuals, tailwhips, and technical tricks while maintaining landing stability
• 11.9" bottom bracket height – Higher BB position compared to race frames improves pedal clearance for grinds and reduces hang-up risk on street obstacles
• 75° head tube angle – Steep head angle provides quick steering response and nimble front-end feel for technical street and park riding
• 72° seat tube angle – Steep seat angle keeps rider weight centered over the bike and positions saddle forward for better balance during seated riding
• 26-tooth sprocket maximum – Clearance for up to 26T chainring accommodates modern street and park gearing with shorter rear ends

Compatibility and Ideal Use Cases

This frame is designed for standard BMX components including Mid BB bottom brackets, integrated or external headsets (verify head tube specifications), and 25.4mm or 31.8mm seat post clamps depending on seat tube diameter. The 26T sprocket clearance works with most modern street and park setups using cassette hubs or freecoasters paired with 25T or smaller sprockets. Best suited for street and park riders who prioritize technical trick performance, quick handling, and responsive back-end feel. The 21" top tube works well for average-height riders; shorter riders (under 5'7") may prefer 20.5"–20.75" options, while taller riders (over 6'0") should consider 21.25" or longer. The short 13.6" rear center excels for manuals, hop tricks, and quick rotations but may feel less stable for riders who prefer longer, more planted setups. The higher 11.9" BB and steep angles suit technical street riding with frequent grinds and ledge work rather than transition-focused or race applications.
