Xterra Fitness FB150 Review 2026
The FB150 is the cheapest, lightest and most compact bike Xterra makes. It is the stripped-back version of the FB350, with the same flywheel and resistance but a smaller frame and none of the extras. At £149 it is the lowest-cost way into the range, though for a little more the FB350 is the more comfortable bike.
Xterra Fitness FB150
Compact folding bike
The verdict
The FB150 is Xterra’s most basic bike, and it is honest about it. You get the same 1.5kg flywheel and eight-level magnetic resistance as the FB350, wrapped in a smaller, lighter X-frame that folds away to the slimmest footprint in the range. At 17kg it is the easiest Xterra to lift, fold and store, which is the entire reason to choose it.
The catch is how little separates it from the FB350. For around £20 more, the FB350 adds a lower-back support pad, an accessory tray and a slightly larger frame, and it is the more comfortable bike to spend time on. So the FB150 only really makes sense if the lowest possible price or the smallest possible size is your single priority. For everyone else, the small step up is worth taking.
Strengths
- Lightest and most compact bike in the range at 17kg
- Folds flat on a small X-frame, with transport wheels
- Cheapest Xterra at £149
- Simple and quick to set up
- Magnetic resistance runs quietly
Watch-outs
- Very light 1.5kg flywheel, little momentum
- No back-support pad or accessory tray
- Smaller frame and seat than the FB350
- 102kg maximum user weight
- Basic LCD, hand-pulse heart rate, no connectivity
Ride feel and real-world experience
The FB150 rides much like the FB350, because mechanically it is almost the same bike. The 1.5kg precision-balanced flywheel and eight magnetic levels make for a quiet, light ride that is comfortable on the lower settings and short on momentum higher up. It is built for gentle, steady pedalling rather than hard work, and within those limits it does the job.
The differences are in comfort and size. The seat is oversized and padded with height adjustment, but there is no lower-back support pad, and the frame is smaller and lighter than the FB350’s, supporting the same 102kg maximum. For shorter riders and tight spaces that compactness is a positive; for longer sessions or larger users, the extra room and back support of the FB350 are worth having. As with every Xterra, this is a light bike, so it feels less planted than a fixed-frame upright like the UB120.
Assembly, size and storage
Storage is where the FB150 makes its case. It is the smallest Xterra set up, at 81cm long by 46cm wide, and folds down to roughly 46cm deep, so it disappears into a narrow gap a larger bike could not. At just 17kg it is easy to fold, lift and wheel away on its transport wheels, and assembly is quick, arriving mostly built. If your priority is a bike that takes up as little room as possible, the FB150 is the one in the range that delivers it.
Console and features
The FB150 uses the same basic battery-powered LCD console as the FB350, displaying speed, distance, time, calories, heart rate and an odometer, with a scan mode, and heart rate read through hand-grip pulse sensors. What it does without is the accessory tray, so there is no built-in spot to rest a phone or tablet. There is no Bluetooth or app connectivity either: this is a ride-to-the-console bike with nothing to set up and nothing to pay for after purchase.
How it compares
The decision here is almost entirely FB150 versus FB350. They share a flywheel, resistance and weight limit, so the FB350’s back pad, accessory tray and larger frame are what your extra £20 buys, and for most people that is money well spent. The FB150 wins only on price, weight and folded size. If you do not need a folding bike at all, the UB120 is the better Xterra for the money, and if you can spend more, the £299 JTX Cyclo-3M is a heavier, smoother bike from a brand with full UK support. You can weigh all three Xterras on the range hub.
Who it is for
The FB150 is for the buyer who wants the cheapest, smallest folding bike they can get for light cardio, and who will trade comfort features to achieve it. It suits very tight spaces, shorter riders and anyone on the tightest budget. If comfort over longer sessions matters, or you are a larger rider, step up to the FB350; if folding is not needed, the UB120 is the better choice.

FitRank breakdown
Performance 2.5
Identical drivetrain to the FB350: a 1.5kg flywheel and eight magnetic levels that suit gentle cardio but carry little momentum. The lowest performance score in the range.
Build quality 2.6
A smaller, lighter folding frame at 17kg with a 102kg limit. It is the most compact Xterra but also the least substantial, and the short parts warranty reflects the price.
Value 3.0
The cheapest bike in the range, but the FB350 offers more comfort for only around £20 more, which holds the value score just below its sibling.
Features 2.6
The most basic in the range. It loses the FB350’s back-support pad and accessory tray, leaving a plain LCD, hand-pulse heart rate and no connectivity.
