Viavito SB1 Review 2026
The Viavito SB1 is a capable budget connected bike, with Bluetooth 5.0, Zwift and Kinomap support and a tidy LED turning knob. The catch is its own stablemate: the cheaper Satori has a heavier flywheel and more resistance levels, which makes the SB1 a harder sell.

Budget connected upright bike

The verdict
Taken on its own, the SB1 is a perfectly good budget upright. The 6kg flywheel gives a smooth enough ride for steady cardio, the 16 levels of computer-controlled magnetic resistance cover the range most riders need, and the LED turning knob makes adjustments quick and intuitive. Bluetooth 5.0 connects it to Zwift and Kinomap, and there is an integrated tablet holder, a water bottle holder, adjustable bars and front transport wheels. As a connected bike for the price, it does the job well.
The problem is the comparison sitting right next to it. The Satori costs £120 less and has a heavier 9kg flywheel and double the resistance levels. The SB1’s Bluetooth 5.0 and turning knob are genuinely nice, but they do not outweigh a lighter flywheel at a higher price. Unless you find the SB1 heavily discounted, or you specifically prefer its knob control and styling, the Satori is the smarter buy from the same brand.
Strengths
- Bluetooth 5.0 with Zwift and Kinomap, no subscription
- LED turning knob for quick resistance changes
- Integrated tablet and water bottle holders
- Adjustable bars and front transport wheels
Watch-outs
- Lighter 6kg flywheel than the cheaper Satori
- Only 16 resistance levels, half the Satori’s
- Costs more than the better-specced Satori
- Basic console and largely plastic construction
Ride feel and real-world experience
On the bike, the SB1 rides smoothly enough for its purpose. The 6kg flywheel is lighter than the Satori’s, so it carries a little less momentum, but for steady cardio and app-led rides it is perfectly pleasant, and the 16 levels of computer-controlled magnetic resistance cover the range most riders will use. The LED turning knob is a nice touch, letting you dial intensity up or down quickly and intuitively mid-ride.
The position and fit are good for a budget bike. The handlebars adjust, the seat is large and padded with horizontal and vertical adjustment, and the oversized pedals with straps keep your feet secure. There is a water bottle holder and an integrated tablet holder for your own device. As with the rest of the range the construction is largely plastic and the console is basic, but nothing here feels flimsy for the money.
The thing you cannot ignore while riding it is that the cheaper Satori does the fundamentals better, with a heavier flywheel and twice the resistance levels. The SB1 is a good bike that happens to be outshone by its own sibling, which is the central fact of this review.
Assembly, size and setup
The SB1 arrives boxed for home assembly, taking most owners around 40 minutes to an hour with the supplied tools. It is a manageable upright that sits on front transport wheels, so one person can move it into place once built. As with any budget bike, check the pedals and bolts are fully tight after the first few rides.
Living with it: noise, footprint and storage
The magnetic resistance keeps the SB1 quiet, so it suits a flat or shared home, and the transport wheels make it easy to reposition. The construction is largely plastic and the console basic, in line with the price, but it is perfectly fine for steady home use. Upkeep is minimal beyond the occasional wipe-down and a periodic bolt check.
Apps and connectivity
The SB1 connects over Bluetooth 5.0 to Zwift and Kinomap, so you can ride virtual routes, join structured workouts and gamify your sessions on your own tablet in the integrated holder. As with all Viavito bikes there is no subscription: you bring whichever app you like, on its own pricing, or ride on the console alone. The newer Bluetooth 5.0 connection is a small edge over some rivals for stability, though in practice the app experience is much the same as the Satori’s.
How it compares
The comparison that matters most is with the Viavito Satori, which costs £120 less and has a heavier 9kg flywheel, 32 resistance levels and a higher 140kg user weight limit against the SB1’s 6kg, 16 and 100kg, making the Satori the better buy unless the SB1 is heavily discounted. Against the Reebok i-Bike, another compact connected bike, the choice is close and comes down to price on the day. If you want a spin-style ride instead, the Viavito Veloria is the range’s indoor cycle, and the specialist JTX Cyclo-3M is the more durable step up.
Who it is for
Buy the SB1 only if you find it discounted close to or below the Satori’s price, or if you specifically prefer its LED turning knob, Bluetooth 5.0 and styling. For almost everyone else, the cheaper, heavier-flywheeled Satori is the better choice from the same brand. If you want a spin-style position, look at the Veloria; if you want a more durable specialist bike, step up to the JTX Cyclo-3M.

Warranty and after-sales
Viavito covers the SB1 with a 2-year home-use warranty, provided you register within 28 days of purchase, otherwise one year, supported through Sweatband. Keep your proof of purchase. As a budget bike with largely plastic construction, its long-term durability is less proven than a premium brand’s, so factor the warranty term into your decision.
FitRank breakdown
Performance 3.4
A 6kg flywheel and 16 magnetic levels give a smooth-enough ride for steady cardio, but it is outdone by the cheaper Satori’s heavier flywheel and wider range.
Build quality 3.6
Largely plastic but well enough assembled, with adjustable seat and bars and transport wheels. Fine for the price.
Value 3.3
The weak point. At £349 it costs more than the better-specced Satori, so it only makes sense when discounted.
Features 3.9
Bluetooth 5.0, Zwift and Kinomap, a turning knob and useful extras. The feature set is its strongest card, and it is genuinely good.
