Description

Bands only · No WHOOP device included · No WHOOP logo

Looking for a high-quality WHOOP replacement band without the branded price tag? Bikers.SG's SportFlex silicone band delivers waterproof, sweatproof, stainproof performance at a fraction of the cost. Every batch goes through multiple rounds of factory quality checks and component inspections — ensuring the metal connectors, clasp fit, and strap durability are on par with the original branded models.

The SportFlex features a high-performance silicone strap paired with a matte silver stainless-steel metal frame in the MG-style curved clasp design. The non-glossy finish gives it a clean, understated look ideal for swimming, training, and high-sweat activities.

Compatible with both WHOOP 5.0 (Peak) and WHOOP MG (Life). We've specifically improved the connector fit for WHOOP 5.0 — addressing the tighter-than-expected fit reported with some branded bands. ECG functionality is supported on WHOOP MG only.

Key Features

  • Not WHOOP-branded – Third-party band, no WHOOP logo. Fully compliant alternative.
  • Factory quality-inspected – Multiple QC checks on components and fit before shipping
  • Improved WHOOP 5.0 fit – Resolved connector tightness issues seen in some branded bands
  • MG-style curved clasp – Matte silver stainless-steel frame with ECG indents
  • Waterproof · Sweatproof · Stainproof – High-performance silicone, safe for swimming and intense workouts
  • Cross-compatible – Fits WHOOP 5.0 (Peak) and WHOOP MG (Life) sensors
  • ECG – Works on WHOOP MG only
  • 4 colour options – Black, Blue, Grey, Green
  • Premium quality, lower price – On-par with branded models, significantly more affordable

Band Care

SportFlex is made of high-performance silicone — waterproof and easy to clean.

  • Wipe clean with a lint-free cloth after each use
  • For a deeper clean, dampen cloth with water or use isopropyl alcohol
  • Rinse with water and let dry completely (lay flat, air dry) before wearing to prevent moisture buildup
  • Clean your WHOOP sensor at least 2–3 times per week to prevent dirt buildup

Skin care note: Silicone is less breathable than knit bands. Extended contact with sweat, soap, or sanitizers may cause irritation. If irritation occurs, remove the band, clean the area with water, and consider rotating to a breathable band like SuperKnit. Keep skin clean and dry, and rotate placement if needed.

Compatibility Notice

Designed and QC-tested for WHOOP 5.0 and WHOOP MG. A small number of units may have a tighter fit — if you experience any difficulty, contact us and we'll make it right with a replacement or refund.

Colour note: Strap colours may appear slightly different in person compared to product images.

Frequently Asked Questions

Is the SportFlex band compatible with WHOOP 5.0 and MG ?
Yes — compatible with both WHOOP 5.0 (Peak) and WHOOP MG (Life). The connector fit has been specifically improved for WHOOP 5.0, addressing the tighter-than-expected fit reported with some branded bands.
Can I swim with the SportFlex band?
Yes. SportFlex silicone is waterproof and sweatproof — built for pool and high-intensity use. Only waterproof bands should be worn when swimming. The silicone material is fully sealed and safe for water exposure.
Does ECG work with the SportFlex band?
ECG works on WHOOP MG only. The matte silver stainless-steel frame has ECG indents but ECG functionality is not supported on WHOOP 5.0. This is a WHOOP hardware limitation, not a band limitation.
How do I prevent skin irritation with the SportFlex band?
Silicone is less breathable than knit bands. Extended contact with sweat, soap, or sanitizers may cause irritation. Keep skin clean and dry, rotate band placement if irritation occurs, and consider switching to a breathable SuperKnit band during extended wear. If irritation occurs, remove the band and allow skin to rest.
How do I clean the SportFlex band?
Wipe clean with a lint-free cloth after each use. For a deeper clean, dampen cloth with water or use isopropyl alcohol. Rinse with water and let dry completely (lay flat, air dry) before wearing to prevent moisture buildup. Clean your WHOOP sensor at least 2-3 times per week to prevent dirt buildup.
Is this an official WHOOP product?
No. This is a third-party replacement band by Bikers.SG. It carries no WHOOP logo and is not manufactured by WHOOP. It is a fully compliant alternative that has undergone multiple rounds of factory quality checks on components, connector fit, and strap quality before shipping.
What colours is the SportFlex band available in?
The SportFlex band is available in 4 colours: Black, Blue, Grey, and Green. Strap colours may appear slightly different in person compared to product images.
Where does the SportFlex band ship from?
All replacement bands ship from Singapore, by Bikers.SG — a registered business under Waaha Technology Pte Limited. Local delivery and self-collection options are available.
