Stages Cycling has just pulled the cover off the SB200, a new indoor smart bike that throws out one of the most familiar ideas in indoor training: the heavy flywheel. Announced on October 5, 2026, it is the brand’s first ground-up product since Giant acquired Stages following its 2024 bankruptcy, and it lands right as riders across the Northern Hemisphere are moving their training indoors for the winter.
What Happened
The SB200 is only the second smart bike Stages has ever built, following the SB20 in 2019. Where the original relied on a 55lb (25kg) flywheel to generate road-like inertia, the SB200 uses a two-stage, freewheeling drive system that creates the same sensation with a freewheel weighing roughly half as much. The whole bike tips the scales at 32.2kg (71lb) and rolls on caster wheels, so it is designed to be shoved into a corner rather than bolted into a pain cave.
Resistance comes from an electromagnetic brake that delivers 400W at 40rpm, more than 1,500W at 12rpm, and a ceiling of 2,500W for sprint efforts. Stages quotes a price of $2,399 (£2,100 / €2,399), with US units shipping from launch day on October 5, the UK following on November 1, and the EU on November 9. It pairs with Zwift, Rouvy, and MyWhoosh over Bluetooth and WiFi, and Stages’ own app adds up to 40 structured workouts.
Why Ditching the Flywheel Matters
For a decade, the unspoken rule of premium smart bikes was simple: a bigger, heavier flywheel meant a more realistic ride feel. Spinning mass smooths out each pedal stroke and mimics the momentum of a real bike coasting down the road. The trade-off is weight, bulk, and a machine that is miserable to move.
Stages is betting it can break that trade-off. “We wanted the SB200 to be more practical and mobile, which meant lighter,” global marketing director Matt Pacocha explained, describing the shift away from the SB20’s 55lb flywheel. By generating inertia through the drive system instead of raw mass, the SB200 aims to feel like the road while weighing far less than its predecessor. If it delivers, it is a meaningful signal for the wider indoor market, where rivals from Wahoo, Wattbike, and Tacx have largely stuck with the heavy-flywheel formula.
The Specs That Stand Out
Beyond the drive system, the SB200 is loaded with the adjustability serious trainers expect. The steel-framed chassis fits riders from 147cm to 208cm, crank length swaps between 165, 170, 172.5, and 175mm, and stabilisers at the base replicate a tyre’s contact patch to allow a touch of natural lateral movement. Interchangeable foot pads let you dial the feel from compliant to rock-solid.
Shifting is handled through 10 programmable buttons with presets for Shimano, SRAM, and Stages’ own Dream Drive, a virtual drivetrain spanning a 0.5:1 to 7:1 ratio range. An integrated display shows power, gear, cadence, and ride time at a glance, so you can run a session without staring at a second screen. For anyone who has wrestled a fiddly trainer app mid-interval, that on-board readout is a quietly practical touch.
What This Means For You
The timing is deliberate. October is when outdoor miles dry up and structured indoor work pays the biggest dividends, and a $2,399 smart bike is a direct pitch to riders weighing a dedicated setup against a wheel-off trainer. If you are shopping, the SB200’s headline advantage is livability: a machine you can actually move is one you are more likely to use.
Hardware is only half the equation, though. A smart bike is only as good as the plan you run on it. If you are setting up for winter, start by building an aerobic foundation with a proper base training block, then layer in intensity with proven sessions like Ronnestad 30/15 intervals. Track your load with Training Stress Score so you build fitness without digging a hole, and do not forget that the gains are made while you sleep and recover, not just while you suffer on the bike.
Key Takeaways
- Stages launched the SB200 smart bike on October 5, 2026, its first ground-up product since Giant’s acquisition.
- It replaces a heavy flywheel with a two-stage freewheel to create road-like inertia at roughly half the spinning weight.
- The bike weighs 32.2kg, rolls on casters, and tops out at 2,500W, priced at $2,399 (£2,100 / €2,399).
- It works with Zwift, Rouvy, and MyWhoosh, fits riders from 147cm to 208cm, and shipped in the US from launch day.
- A smart bike only pays off with a plan, so pair it with structured base and interval work this winter.
