1. TSB Living 13kg Flywheel Spin Bike – Best Overall
Best for riders who want one solid all-rounder. The TSB Living 13kg spin bike is the best overall pick because its 13kg commercial-grade stainless steel flywheel and quiet belt drive deliver a smooth, road-like pedal stroke without the noise of a chain. The frame is powder-coated stainless steel measuring 99cm long by 49cm wide, with the seat adjusting from 89cm to 101cm and a maximum rider height of 185cm, so it suits most adults up to 120kg. The bright yellow finish stands out next to the usual black gym gear, and the extra-thick padded PU-leather saddle, toe-strap pedals and a five-function LCD (time, speed, distance, calories and pulse) round out a well-equipped budget bike. Built-in pulse sensors and a phone holder are handy touches for following along with an app.
Setup is straightforward and the bike arrives flat-packed at around 40kg, so a second pair of hands helps. Owners across NZ listings call it a smooth, solid ride and good value, with several saying they use it daily. The honest trade-offs: a few report the bike develops a squeak even when fully bolted, the seat is firm until you adjust to it, and the odd unit has shipped with a faulty LCD screen. TSB Living does not publish a specific warranty period or confirm the resistance type on the page.
Pros
- 13kg steel flywheel gives a smooth, weighty ride
- Quiet belt drive that will not wake the house
- Adjustable padded seat, pulse sensors and phone holder
Cons
- Some owners report a squeak over time
- Firm seat out of the box
- No stated warranty period or resistance type
Key specs: 13kg flywheel, belt drive, powder-coated stainless steel frame, LCD console, max user 120kg, max height 185cm, seat height 89-101cm, model PR2931, colour yellow, assembly required.
2. TSB Living 18kg Flywheel Spin Bike – Best for Serious Training
Best for committed riders chasing heavier, more momentum-driven sessions. Stepping up to the 18kg flywheel is the main reason to choose this grey model over its 13kg sibling: the extra mass carries through the dead spot at the top of each stroke, so sprints and standing climbs feel closer to a real road bike. It shares the same powder-coated stainless steel frame at 99cm by 49cm, the PU-leather padded seat adjusting 89cm to 101cm, the five-function LCD with pulse sensors, and the quiet belt drive. TSB also lists adjustable rear suspension and a variable-grip handlebar on this one, plus a phone holder for streaming classes.
Harvey Norman NZ shoppers rate the PROTRAIN flywheel bike around 4.0 out of 5, with one noting the assembly instructions were easy to follow even if a couple of parts were fiddly to fit. The heavier flywheel means a heavier box, near 43kg packed, so moving and assembling it solo is harder than the lighter models. The same caveats as the 13kg carry over: the seat is firm, a squeak can develop, and the rider weight cap is still 120kg, so it is built for road feel rather than heavy-duty commercial loads.
Pros
- 18kg flywheel for genuine road-like momentum
- Adjustable rear suspension and variable-grip bars
- Quiet belt drive and full LCD with pulse sensors
Cons
- Heavy box makes solo assembly awkward
- Still capped at 120kg rider weight
- Firm seat and occasional squeak reported
Key specs: 18kg flywheel, belt drive, powder-coated stainless steel frame, LCD console, max user 120kg, max height 185cm, seat height 89-101cm, model PR2932, colour grey, assembly required.
3. TSB Living 11kg Flywheel Spin Bike – Best Compact Pick
Best for smaller homes, shorter riders and seniors easing into indoor cycling. The 11kg model is the most compact of the three TSB bikes, with a smaller 85cm by 48cm footprint and a lower seat range of 75cm to 89cm that genuinely fits riders under about 175cm. Several NZ owners single it out as a great size for shorter people and older users who found full-size bikes too stretched out. It keeps the same powder-coated steel frame, quiet belt drive, padded PU-leather seat, toe-strap pedals, pulse sensors and LCD console as its bigger siblings, plus a phone holder, so the experience is the same; just scaled down. At around 30kg packed it is also the easiest of the trio to carry inside and put together.
The lighter 11kg flywheel means a slightly less weighty pedal feel than the 13kg and 18kg bikes, which keen cyclists will notice on sprints. The bigger limit is capacity: a 100kg maximum rider weight and 175cm height cap rule it out for taller or heavier users, who should size up to the 13kg or 18kg. A handful of owners also mention that some assembly pieces are awkward to seat properly. For low-impact cross-training alongside it, a set of adjustable dumbbells rounds out a compact home workout corner.
Pros
- Compact footprint and low seat suit shorter riders
- Lightest of the three to move and assemble
- Same belt drive, LCD and padded seat as the larger models
Cons
- 100kg weight and 175cm height limits are restrictive
- 11kg flywheel feels lighter on sprints
- Some assembly parts fiddly to fit
Key specs: 11kg flywheel, belt drive, powder-coated stainless steel frame, LCD console, max user 100kg, max height 175cm, seat height 75-89cm, model PR66703 (SBIKE-01 / YB-330), colour grey, assembly required.
4. Genki Belt Drive Spin Bike – Best Budget Buy
Best for first-time buyers who want the most bike for the least money. The Genki belt-drive spin bike pairs a 13kg flywheel with a quiet belt drive and a sturdy steel frame rated to 120kg, which is a lot of hardware at the budget end. Resistance is adjustable through a friction knob with an emergency stop brake, and the package includes practical extras you do not always get this cheap: floor levellers for uneven floors, transport wheels to roll it out of the way, an LCD that tracks time, distance and calories, and adjustable handlebars, pedals and a padded saddle. The black-and-red frame looks the part next to pricier bikes.
Owner feedback across NZ and Australian listings is broadly positive on the quiet ride and value, but budget build quality shows in a few areas. The most common complaint is a pedal working loose or cross-threading over time, so checking and tightening the cranks early is wise. Taller riders note the handlebars and seat sit a little low at full extension, and one owner mentioned surface rust appearing where sweat was not wiped down, which is worth a quick towel after each ride. Genki does not publish exact assembled dimensions, so measure your space against the gallery photos before buying.
Pros
- Strong value with a 13kg flywheel and 120kg frame
- Transport wheels, floor levellers and emergency brake included
- Quiet belt drive praised by owners
Cons
- Pedals can loosen or cross-thread over time
- Bars and seat sit low for very tall riders
- Assembled dimensions not published
Key specs: 13kg flywheel, belt drive with adjustable friction resistance, steel frame, LCD monitor, transport wheels, floor levellers, emergency stop, max user 120kg, BestDeals product 38031, assembly required.
5. Genki Magnetic Exercise Bike – Best for Quiet Rides
Best for apartments, early mornings and anyone who hates equipment noise. This Genki model swaps the usual friction pad for magnetic resistance, which combines with a belt drive to give a near-silent ride; there is no pad rubbing the flywheel, so it stays quiet even at higher resistance. Magnetic resistance is also lower maintenance because nothing wears against the wheel. Owners describe it as compact and easy to assemble, with one reporting more than 5,000km logged over two years with no visible wear, which is a strong durability signal for a budget bike. The padded saddle and adjustable setup follow the familiar indoor-cycle template.
The honest caveat here is information: BestDeals lists this bike with a magnetic, belt-drive description but does not publish the flywheel weight, dimensions or rider weight cap on the page, so confirm those details with the retailer before buying if they matter to you. On the experience side, the saddle runs firm like most bikes in this class, and one long-term owner noted light rust forming from sweat, so a wipe-down after sessions helps. Magnetic bikes also usually cost a little more than friction equivalents, which is the price of the quiet.
Pros
- Magnetic resistance gives a near-silent ride
- Low maintenance with no pad wearing on the flywheel
- Owner reports of long, trouble-free use
Cons
- Flywheel weight, dimensions and weight cap not published
- Saddle is firm like most in this class
- Magnetic resistance usually costs a little more
Key specs: magnetic resistance, belt drive, adjustable padded seat, LCD monitor, indoor cycling bike, BestDeals product 37802, model not specified by retailer, assembly required.
6. Genki Indoor Cycling Bike – Best for Heavier Riders
Best for larger riders who want a budget bike that will not feel flimsy. The standout figure on this Genki model (sold as model YS-7702) is its 150kg maximum user weight, the highest in this guide, supported by 50mm thickened frame tubes with a scratch-resistant coating and a shock-absorption system. It runs a 13kg chromed flywheel with a whisper-quiet belt drive and adjustable friction resistance, plus an emergency stop button for sudden halts. The black-and-red bike includes a PU-leather saddle, pulse sensors in the handlebars, transport wheels and levelling knobs under the rear stabiliser, and an LCD that cycles through scan, time, speed, distance, calories, odometer and pulse.
For the money it is a lot of frame and capacity, and the shock absorption is a genuine comfort plus on a hard floor. The usual budget limitations apply: the LCD readouts, especially the pulse reading, are best treated as rough guides rather than gym-grade data, and a friction pad will eventually wear and can squeak, needing occasional adjustment. Stock is also limited at the time of writing, so it may not hang around. A fitness tracker gives far more accurate heart-rate and calorie numbers if you train to data.
Pros
- 150kg weight capacity, the highest here
- Thickened frame tubes and shock absorption
- Whisper-quiet belt drive with full LCD readouts
Cons
- LCD and pulse readings are only rough guides
- Friction pad wears and can squeak over time
- Low stock at the time of writing
Key specs: 13kg chromed flywheel, belt drive with adjustable friction resistance, 50mm thickened frame, shock absorption, LCD monitor, pulse sensors, transport wheels, max user 150kg, model YS-7702 (BestDeals product 79270), colour black and red, assembly required.
How to choose a spin bike in NZ
Flywheel weight: Heavier flywheels carry more momentum and feel smoother, closer to riding on the road. In this guide that ranges from a light, beginner-friendly 11kg up to a road-like 18kg. For most home riders, 13kg is the sweet spot, while keen cyclists will prefer the heavier wheel.
Resistance type: Friction resistance uses a felt pad pressing the flywheel; it is cheap and gives a strong, tactile load but the pad wears and can squeak. Magnetic resistance is near-silent and low maintenance because nothing touches the wheel, but it usually costs a little more. Choose magnetic if quiet matters most.
Fit and weight capacity: Check the seat height range and maximum rider height and weight before buying. The compact 11kg bike caps out at 100kg and 175cm, while the Genki YS-7702 supports up to 150kg. Taller or heavier riders should size up rather than push a bike to its limit.
Noise, space and extras: Belt drives are quieter than chains, which matters in apartments and shared homes. Look for transport wheels, floor levellers and a phone holder if you stream classes. Measure your floor space against the assembled dimensions, and plan for flat-pack assembly on every bike here. An elliptical trainer is worth a look if you want lower-impact cardio instead.
Verdict
For most New Zealand home riders, the TSB Living 13kg Flywheel Spin Bike is the best all-round choice, balancing a smooth 13kg flywheel, a quiet belt drive and a comfortable adjustable seat. Keen cyclists chasing road feel should step up to the 18kg model, while shorter riders and smaller spaces are best served by the 11kg. On a tight budget the Genki belt-drive bike delivers the most value, the Genki magnetic bike wins for near-silent rides, and the Genki YS-7702 is the pick for heavier riders thanks to its 150kg capacity. For recovery between hard sessions, a massage gun is a worthwhile add-on.

FAQs
What is the difference between a spin bike and an exercise bike?
A spin bike mimics a road bike, with a forward-leaning riding position, a heavy flywheel and resistance you adjust by feel for standing climbs and sprints. A standard upright or recumbent exercise bike sits you more upright with preset programmes and is gentler. Spin bikes suit interval and high-intensity training.
How much should you spend on a spin bike in NZ?
Budget belt-drive spin bikes in NZ start around the low hundreds, mid-range bikes with heavier flywheels and better consoles sit higher, and serious or commercial-grade bikes run well over a thousand dollars. For most home riders, a solid 13kg flywheel belt-drive bike offers the best balance of price, ride quality and durability.
Is a heavier flywheel better on a spin bike?
A heavier flywheel carries more momentum, so the pedal stroke feels smoother and more road-like, which is why keen cyclists prefer 16kg to 18kg wheels. Lighter 11kg to 13kg flywheels are easier to start and fine for general fitness. On magnetic bikes the resistance system matters more than raw flywheel weight.
Magnetic or friction resistance, which is better?
Magnetic resistance is near-silent and low maintenance because nothing touches the flywheel, making it ideal for apartments, but it costs a little more. Friction resistance uses a felt pad for a strong, tactile load at a lower price, though the pad wears and can squeak over time. Choose based on noise tolerance and budget.
Can you lose weight using a spin bike?
Yes. Indoor cycling burns significant calories and a vigorous session can burn several hundred calories, so paired with a balanced diet a spin bike supports weight loss. Consistency matters more than intensity at first; regular rides of 30 to 45 minutes several times a week deliver steady, sustainable results over time.
Are spin bikes good for your knees?
Spin bikes are low-impact, so they are generally gentle on knees compared with running. Set the seat height so your knee has a slight bend at the bottom of the stroke, avoid pushing too much resistance too soon, and warm up first. Anyone with existing knee issues should check with a health professional before starting.
Do spin bikes need maintenance?
Yes, but it is light. Wipe the frame down after sweaty sessions to prevent rust, periodically check and tighten the pedals, crank bolts and seat clamp, and keep the bike on level floor. Friction bikes need the felt pad replaced when worn, while belt and magnetic systems need very little attention.
Is it OK to use a spin bike every day?
For most healthy adults, daily spinning is fine if you vary the intensity, mixing easy recovery rides with harder interval days rather than going flat out every time. Listen to your body, allow rest if you feel run down, and build duration gradually. Beginners should start with three to four sessions a week.
