Xterra Fitness UB120 Review 2026
The UB120 is the bike Xterra gets most right. It is a plain, non-folding upright with the heaviest flywheel and the highest weight limit in the range, and it regularly sells for under £100. For light, no-fuss cardio at home, that is a lot of bike for the money.
Xterra Fitness UB120
Non-folding upright bike
The verdict
The UB120 is the pick of the Xterra range, and the reason is simple: it is the only one built like a bike you keep in place rather than fold away. The 4kg flywheel is more than double the weight of the one in the folding FB350 and FB150, the frame supports up to 130kg, and the upright stance feels steadier underfoot than the lightweight X-frames. None of that makes it a performance machine, but it does make it the most usable Xterra for regular, gentle cardio.
Where it earns its FitRank is value. At the £199 list price it is unremarkable, but it spends much of its life on offer at around £99, and at that money a non-folding upright from an established brand, with a tablet holder and a 130kg limit, is hard to fault. The compromises are the ones you would expect: a single-button LCD console, manual resistance, no app support, and a height window of roughly 155cm to 185cm that rules out the tallest riders.
Strengths
- Heaviest flywheel in the Xterra range at 4kg
- 130kg maximum user weight, the highest here
- Tablet holder built in
- Strong value when discounted to around £99
- Transport wheels for moving it aside
Watch-outs
- Does not fold, so it needs a permanent spot
- Single-button console is very basic
- No app connectivity or Bluetooth
- Suits riders roughly 155cm to 185cm
- Hand-pulse heart rate only
Ride feel and real-world experience
For an entry-level upright, the UB120 rides better than the folding Xterras, and the flywheel is the reason. At 4kg it still counts as light, so you will not get the planted, road-like momentum of a heavier spin bike, but it carries enough inertia to smooth out the pedal stroke and keep the lower resistance levels from feeling twitchy. The magnetic resistance runs quietly, with eight levels set by hand on the dial, which is plenty of range for steady cardio even if it will not satisfy anyone chasing hard interval work.
Comfort is handled by an oversized, padded, height-adjustable seat and soft-foam multi-grip handlebars, and the 130kg weight limit gives the frame a reassuring margin that the folders lack. The one fit caveat to take seriously is height: Xterra lists the UB120 as suitable for users between roughly 155cm and 185cm, so if you are taller than six foot, look elsewhere in the range or step up a class.
Assembly, size and storage
The UB120 is straightforward to build, arriving largely pre-assembled with the main job being the stabilisers, seat, handlebars and pedals. At 18kg it is light to manoeuvre, and transport wheels at the front let you tip and roll it out of the way. The trade-off for that lightness is that it does not fold, so unlike the FB350 and FB150 it needs a permanent home. Its footprint is compact at 88cm by 56cm, so a spare corner is enough, but plan for it to stay put rather than disappear into a cupboard between sessions.
Console and features
The UB120 keeps things deliberately simple. A clear LCD console operated by a single button tracks speed, distance, time, calories and heart rate through hand-grip pulse sensors, and that is the extent of the electronics. There is no Bluetooth and no app connectivity, so this is a ride-and-go bike rather than a connected one. The useful extra is the built-in tablet holder: prop a phone or tablet on it and you can follow a free spin class on YouTube or stream whatever keeps you pedalling, which covers the entertainment gap most budget bikes leave open.
How it compares
Within the range, the UB120 is the clear pick over the folding FB350 and FB150: it has a heavier flywheel, a higher weight limit and a steadier upright frame, and the only thing it gives up is the ability to fold away. If folding is your priority, the FB350 is the one to read up on; if it is not, the UB120 is the better bike. Against other budget uprights, including the Sweatband house-brand Viavito range, it competes mainly on its sale price. If you want a heavier flywheel, app connectivity and a frame built for harder training, the step up is the £299 JTX Cyclo-3M, the entry point to a far more capable range.
Who it is for
The UB120 suits anyone who wants light, regular cardio at home and does not need their bike to fold or connect to anything. It is a sensible choice for a returning exerciser, a steady daily pedal in front of the television, or a second machine for a spare room, especially at its sale price. If you are taller than six foot, want structured training or expect app classes and a heavier ride, treat it as a stepping stone and look higher up.

Warranty and after-sales
The UB120 comes with a home-use warranty of one year on the frame and 90 days on parts, which is standard for a bike at this price and in line with the rest of the Xterra folding range. It is not the long, multi-year cover you get from premium brands, so it reflects the UB120’s entry-level position, but for a sub-£100 purchase backed by an established name with UK retail support through Sweatband, it is reasonable reassurance.
FitRank breakdown
Performance 3.0
The 4kg flywheel is the heaviest in the range and gives a noticeably smoother stroke than the folders, but it is still light by wider standards, so the ride suits steady cardio rather than intense or standing efforts.
Build quality 3.2
The strongest of the structural pillars here. A 130kg weight limit and a fixed upright frame make it the sturdiest Xterra, though the 18kg mass and short parts warranty keep it firmly in budget territory.
Value 3.6
The highest-scoring pillar. At its frequent £99 sale price, a non-folding brand upright with a tablet holder and a high weight limit is a lot of usable bike for the money.
Features 2.9
Deliberately minimal. A single-button LCD, hand-pulse heart rate and a tablet holder cover the basics, but there is no connectivity, no programmes and no powered resistance.
