Xterra Fitness Exercise Bikes: The Full Range Compared

Xterra Fitness sits right at the entry end of the home cardio market: light, foldable, cheap, and built for casual use rather than serious training. Three models reach the UK, and the appeal across all of them is the same. They take up little room, cost little money, and ask nothing of you beyond a couple of AA batteries. Here is how the FB350, FB150 and UB120 compare, where each earns its keep, and the point at which it is worth spending more.

The short version

All three Xterra bikes are budget machines and we have scored them as such. The two folding models share a very light 1.5kg flywheel, so the pedal stroke is functional rather than fluid. The non-folding UB120 is the pick of the range thanks to a heavier 4kg flywheel, a far higher 130kg weight limit, and a sale price that regularly drops to under £100. If you want something for gentle, occasional cardio in a small flat, Xterra does the job. If you want a ride that feels like a proper bike, or you plan to train with any intensity, this is not the range for you.

  • Heaviest flywheel of the three (4kg)
  • 130kg max user weight, the sturdiest
  • Tablet holder built in
  • Strong value at the £99 sale price
  • Does not fold
  • Single-button console is bare-bones
  • Best for riders 155cm to 185cm
  • No heart-rate readout in the feedback set

The UB120 is the only Xterra that does not fold, and it is the better bike for it. The 4kg flywheel is still light by serious standards, but it carries noticeably more momentum than the 1.5kg folders, so the pedal stroke is smoother and the lower resistance levels feel less twitchy. The 130kg weight limit is genuinely useful and well ahead of the folding pair. Add a tablet holder and a price that frequently falls to £99, and this is the one in the range we would actually recommend. The catch is the height window: Xterra lists it for users between roughly 5ft and 6ft, so taller riders should look elsewhere.

  • Folds flat for easy storage
  • Padded seat with lower-back support pad
  • Accessory tray for a phone or remote
  • Transport wheels fitted
  • Very light 1.5kg flywheel
  • 102kg max user weight
  • No tablet holder
  • Basic scan-style LCD only

The FB350 is the more comfortable and better-equipped of the two folders. You get a larger, padded seat with a cushioned lower-back pad, an accessory tray and a slightly more substantial frame than the FB150. None of that changes the fundamental limitation: at 1.5kg, the flywheel is too light to give the ride any real flow, so this is a bike for gentle, steady pedalling rather than building momentum. As a fold-away option for light cardio in a small space, it is a reasonable buy at £169. Just go in expecting an entry-level feel.

  • Smallest footprint, lightest at 17kg
  • Folds flat, transport wheels fitted
  • Cheapest in the range at £149
  • Simple, quick to set up
  • Same light 1.5kg flywheel as the FB350
  • No back-support pad or accessory tray
  • Smaller frame and seat than the FB350
  • 102kg max user weight

The FB150 is the stripped-back version of the FB350: the same 1.5kg flywheel and eight manual resistance levels, but a smaller frame, a simpler seat and none of the extras. It is the lightest and most compact bike here, which is the whole point of it, and at £149 it is the cheapest way into the range. For the sake of £20, though, the FB350 adds a back-support pad and an accessory tray and is the more comfortable bike, so the FB150 only really makes sense if absolute compactness or the lowest possible price is the priority.

Worth spending more?

Xterra covers the floor of the market, and for occasional, gentle use that is fine. But if you intend to ride regularly, train with any intensity, or you simply want a bike that feels solid underneath you, the jump in quality from here is large and worth it. A heavier flywheel transforms the ride, and a proper console or app connection keeps you coming back.

That is where JTX Fitness comes in. Its bikes use far heavier flywheels, sturdier frames and longer warranties, and they hold their resale value in a way budget machines never do. The JTX Studio Pro is our benchmark indoor bike, and the range scales down to the £299 Cyclo-3M. If your budget can stretch, start with JTX rather than replacing an Xterra in eighteen months.

Who Xterra Fitness is for

Xterra makes sense for a fairly specific buyer. You want light cardio at home without giving up half a room to a machine. You value the folding design and the low price more than ride quality. You are returning to exercise gently, topping up activity between walks, or want something undemanding to spin on while watching television. For all of that the range delivers, and the UB120 in particular is hard to argue with at its sale price.

It is not for anyone chasing fitness gains through structured training, intervals or long sessions. The light flywheels, manual resistance and basic consoles will frustrate you quickly, and the folding models cap out at 102kg. If any of that describes you, treat Xterra as a stepping stone rather than a destination.

Frequently asked questions

Which Xterra exercise bike is best?
The UB120. It has the heaviest flywheel at 4kg, the highest weight limit at 130kg, a tablet holder, and it frequently sells for around £99. The trade-off is that it does not fold and suits riders between roughly 155cm and 185cm.
Do Xterra bikes fold away?
The FB350 and FB150 both fold flat on a compact X-frame and have transport wheels for moving them aside. The UB120 does not fold, so it needs a permanent spot.
Are Xterra exercise bikes any good for serious training?
No. These are entry-level bikes built for light, occasional cardio. The 1.5kg flywheels on the folders and 4kg on the UB120 are too light for intense or sustained training, and there is no app connectivity or powered resistance. For regular or harder workouts, step up to a heavier machine such as those in the JTX range.
What is the weight limit on an Xterra bike?
The two folding models, the FB350 and FB150, support up to 102kg. The non-folding UB120 supports up to 130kg.
Do they need mains power?
No. All three run their LCD console on AA batteries, which are included, and the magnetic resistance is adjusted manually, so there is nothing to plug in.
