What Wattbike does

Wattbike is a UK-based designer and manufacturer of precision smart indoor cycling equipment, founded in 1999 in partnership with British Cycling's Performance Director Peter Keen and operating from Nottingham. The company's product portfolio comprises the Atom (precision home cycling, ±1% power accuracy with electromagnetic resistance and 1,000 readings/second), the Proton (premium smart bike for guided home workouts and shared household use), the Air-Pro (self-powered commercial/elite conditioning bike launched 2025), and the AtomX (commercial smart bike). Core proprietary technology includes the Pedalling Effectiveness Score (PES), Polar View pedalling technique visualisation, and an electromagnetic resistance system, with the free Wattbike Hub App and subscription-based Hub+ providing structured training, VO2 Max testing, Healthspan Score tracking, and integrations with Zwift, Rouvy, and Strava.

The business model combines one-time hardware sales (Atom £2,349, Proton £1,649, Air-Pro £2,999) with a recurring Hub+ software subscription, accessories, servicing, and reconditioned units. Wattbike serves three primary customer segments in parallel: elite athletes and professional sports teams (all 20 Premier League clubs, 12 Champions League winners, 6 of 6 Six Nations rugby teams, British Cycling, USA Cycling, Australia Cycling, NFL, US Navy SEALs, British Army), commercial gyms and health clubs (Virgin Active, Third Space, Bupa, David Lloyd), and serious home fitness enthusiasts reached via wattbike.com DTC e-commerce with regional storefronts for the UK, US, Ireland, and Australia, plus financing through DivideBuy (Zopa Bank). Distribution spans six continents through direct sales, a dedicated commercial division at commercial.wattbike.com, showrooms, and international distribution partners.

Since July 1, 2025, Wattbike has operated as a wholly-owned subsidiary of Interactive Strength Inc. (NASDAQ:TRNR), a multi-brand fitness roll-up that also owns CLMBR, FORME, and (as of March 2026) Ergatta. Wattbike's individual revenue is no longer disclosed separately; TRNR reported $11.5 million full-year 2025 revenue with Wattbike consolidated from July 1, $20.7 million 2025 pro forma including full-year Wattbike, and >$30 million 2026 pro forma guidance. Stephen Loftus leads the brand as CEO, with co-founder Ian Wilson (1979 World Rowing Champion) among the founding team.

Direct peers

• Stages Cycling: Stages manufactures commercial indoor bikes (Stages SC) and power meters used by elite cycling teams. Overlaps with Wattbike in commercial gym and professional cycling markets, both prioritizing power measurement accuracy and durability.
• Peloton Interactive: Peloton is the most direct competitor in the connected indoor cycling market, offering premium smart bikes (Bike, Bike+) with subscription-based content. Wattbike competes on accuracy and elite validation; Peloton competes on scale, content library, and brand.
• Echelon Fitness: Echelon offers connected smart bikes (EX-7s, Smart Connect Bike) at lower price points than Wattbike, targeting the connected home fitness segment with subscription content. Direct competition in the DTC connected bike market.
• Keiser (Keiser M Series): Keiser M3i and M Series indoor cycles are commercial-grade indoor bikes used in health clubs and studios. Direct overlap with Wattbike's commercial AtomX offering in fitness facilities and performance labs.
• Wahoo Fitness: Wahoo's KICKR smart trainers and KICKR Bike compete directly with Wattbike's smart bikes, particularly for serious cyclists and triathletes. Both focus on power accuracy and integration with Zwift/Rouvy, serving overlapping enthusiast and professional segments.
• NordicTrack (iFit): NordicTrack's Commercial S22i and similar studio bikes compete in connected indoor cycling. NordicTrack/iFit leverages broader equipment range and instructor-led content, overlapping Wattbike's home fitness segment with broader mass-market positioning.
• Garmin (Tacx): Garmin's Tacx smart trainers (Neo, Flux) compete directly with Wattbike in the high-end indoor training market. Both target serious cyclists needing accurate power data; Garmin adds a broader wearables/cycling computer ecosystem advantage.

Emerging players

• Zwift: Zwift is the dominant virtual cycling platform and a Wattbike integration partner. While complementary today (Wattbike hardware integrates with Zwift), Zwift's own smart bike (Zwift Ride) represents emerging direct competition in the connected indoor cycling stack.
• MYZONE: MYZONE provides heart-rate-based fitness tracking for group fitness and commercial gyms. Complementary ecosystem player that overlaps Wattbike's commercial/fitness club segment with performance-tracking infrastructure rather than hardware.

Broad incumbents

• Bowflex: Bowflex is a broader incumbent in home fitness equipment. Their VeloCore indoor cycling bike and JRNY platform overlap with Wattbike's home fitness segment, though Bowflex competes more on variety of equipment than cycling-specific precision.
