The best exercise bike in NZ overall is the 18kg flywheel spin bike from TSB Living, thanks to its heavy flywheel, sturdy frame and 120 kg user rating that together give the smoothest ride in this guide. Riders short on space should look at the folding X-Bike, while anyone wanting a gentler, supported workout will prefer the recumbent X-Bike with rope. This guide compares nine exercise bikes stocked in New Zealand, from belt-drive spin bikes to magnetic folding and convertible models, ranked by what each does best with real flywheel weights, resistance types and user limits.
An exercise bike is one of the easiest pieces of home cardio kit to live with, and it slots neatly alongside a wider setup of home gym equipment and adjustable dumbbells for full-body training at home.

1. Genki Magnetic Exercise Bike – Best Magnetic Spin Bike
Best magnetic spin bike: the Genki Magnetic Exercise Bike pairs a magnetic resistance system with a quiet belt drive, so it gives a near-silent, smooth ride that suits apartments and shared homes where noise matters.
Built around a commercial-style spin frame with a heavy weighted flywheel, it carries the highest original recommended price in this lineup and a 5-star rating across five reviews on Bestdeals, pointing to a more substantial machine than entry-level bikes.
Because the magnetic pads never touch the flywheel there is little to wear out and the ride stays virtually silent. Owners of Genki spin bikes report years of trouble-free use, with one logging more than 5,000 km across two years of riding.
An LCD monitor tracks time, speed, distance, calories and pulse, the seat and handlebars adjust to fit different riders, and toe-strap pedals keep feet planted during standing sprints.
The trade-offs are practical: it ships flat-packed and needs assembling, the console is a basic non-backlit LCD rather than an app screen, and the heavier magnetic frame is harder to move than a folding bike.
Pros
- Near-silent magnetic resistance with quiet belt drive
- Heavy flywheel for a smooth, stable ride
- LCD tracks time, speed, distance, calories and pulse
- Strong owner reliability reports
Cons
- Flat-packed, so home assembly is required
- Basic non-backlit console, no built-in app
Key specs: magnetic resistance with belt drive; heavy weighted flywheel; LCD monitor; adjustable seat and handlebars; toe-strap pedals; Bestdeals product code 37802.
2. Genki Spin Exercise Bike – Best for Bold Style
Best for bold style: the Genki Spin Exercise Bike brings a standout red colourway and a belt-drive spin setup, so it adds personality to a home gym while still delivering a genuine indoor-cycling workout.
The red steel frame is the visual hook, and the belt-drive system keeps pedalling quiet and smooth, a clear step up from older chain-driven bikes. Like its stablemates it holds a 5-star rating across five Bestdeals reviews.
An LCD monitor shows time, speed, distance, calories and pulse so progress is easy to follow, and the adjustable seat and handlebars let more than one person in the household share it.
Genki spin bikes in this class run a stainless steel flywheel that builds steady momentum for a road-like feel. Testers note the ride is smooth at moderate cadence, though it can feel busier at very high speeds.
Trade-offs to weigh: assembly is required out of the box, the bright red will not suit every room, and there is no backrest, so it is built for active cycling rather than relaxed pedalling.
Pros
- Eye-catching red finish
- Quiet belt-drive spin ride
- LCD tracks time, speed, distance, calories and pulse
- Adjustable seat and handlebars
Cons
- Home assembly required
- Bold colour will not suit every space
Key specs: belt-drive spin bike; stainless steel flywheel; LCD monitor; adjustable seat and handlebars; red finish; Bestdeals product code 25582.
3. Spin Bike 18kg Flywheel – Best Overall
Best overall: the 18kg flywheel spin bike from TSB Living tops the list thanks to its heavy 18 kg flywheel, sturdy frame and 120 kg user rating, giving the smoothest and most stable ride here for committed home cyclists.
The 18 kg flywheel is the heaviest in this guide and is what gives the pedal stroke its momentum, smoothing out the dead spots so the ride feels closer to a real road bike. A belt-drive system keeps the noise down.
It measures 99 cm long, 49 cm wide and 97 to 111 cm tall with an adjustable seat, seatpost and handlebars, and the steel frame weighs about 43 kg, which is exactly why it stays planted during hard standing efforts.
It supports riders up to 120 kg and 185 cm, the highest limits in this lineup, and an LCD monitor keeps track of time, speed, distance and calories.
The trade-offs come from that solidity: at around 43 kg it is heavy to shift and has no folding mechanism, so it needs a permanent spot, and it arrives flat-packed for assembly.
Pros
- Heaviest 18 kg flywheel for the smoothest ride
- Highest 120 kg user weight limit here
- Sturdy steel frame that stays planted
- Belt drive keeps it quiet
Cons
- Heavy at around 43 kg and does not fold
- Assembly required
Key specs: model PR2932; 18 kg flywheel; belt drive; 99 x 49 x 97-111 cm (L x W x H); about 43 kg; max user 120 kg and 185 cm; adjustable seat, seatpost and handlebars; LCD; grey.
4. Spin Bike 11kg Flywheel Orange – Best Budget Pick
Best budget pick: the 11kg flywheel spin bike in orange brings PROTRAIN spin-bike basics at the lower end of the range, so it suits newer riders who want a smooth belt-drive workout without overspending.
The 11 kg flywheel is lighter than the 18 kg model, which keeps both the price and the weight down while still giving steady momentum for everyday cardio. A powder-coated stainless steel frame and belt drive keep it quiet and rust-resistant.
It stands 85 cm long, 48 cm wide and 100 to 109 cm tall, with a seat that adjusts from 75 to 89 cm, a PU-leather padded saddle, toe-strap pedals and built-in pulse sensors, plus an LCD that shows time, speed, distance, calories and pulse.
The orange colourway is the cheerful point of difference for a garage or spare room, and it supports riders up to 100 kg and 175 cm.
Trade-offs: the lighter flywheel feels slightly less planted than heavier bikes during sprints, the 100 kg limit rules out some users, and assembly is required.
Pros
- Lower-cost entry into a real spin bike
- Rust-resistant powder-coated steel frame
- Padded PU saddle, pulse sensors and phone holder
- Bright orange finish stands out
Cons
- Lighter 11 kg flywheel feels less planted in sprints
- Modest 100 kg user weight limit
Key specs: model PR2930; 11 kg flywheel; belt drive; powder-coated stainless steel frame; 85 x 48 x 100-109 cm (L x W x H); seat 75-89 cm; max user 100 kg and 175 cm; toe-strap pedals; LCD; orange.
5. Spin Bike 11kg Flywheel Grey – Best Understated Style
Best understated style: the 11kg flywheel spin bike in grey is the same lightweight spin platform in a neutral grey finish, so it blends into a lounge or office better than brighter bikes.
It shares the 11 kg belt-drive flywheel and a similar footprint of 85 cm long, 48 cm wide and 100 to 109 cm tall, with an adjustable seat and handlebars and an LCD that tracks time, speed, distance, calories and pulse.
The muted grey frame is the main difference from the orange version, which makes it the easier choice for shared living spaces where a loud colour would clash. It supports riders up to 100 kg and 175 cm tall.
Pulse grips and a phone holder let riders gauge effort and follow a class on a tablet, and the belt drive keeps the noise low enough for early-morning sessions before the house wakes up.
Trade-offs: like the orange model the 11 kg flywheel is lighter than premium bikes, the 100 kg user limit is modest, and it arrives flat-packed for home assembly.
Pros
- Neutral grey finish suits shared rooms
- Quiet 11 kg belt-drive flywheel
- Pulse grips and phone holder
- Same compact spin footprint
Cons
- Lighter flywheel than premium bikes
- Modest 100 kg user weight limit
Key specs: model PR66703 (barcode YB-330); 11 kg flywheel; belt drive; about 85 x 48 x 100-109 cm (L x W x H); max user 100 kg and 175 cm; adjustable seat and handlebars; LCD; grey.
6. X-Bike Folding Magnetic Exercise Bike – Best Foldable
Best foldable: the X-Bike Folding Magnetic Exercise Bike folds down on a steel X-frame, so it is the pick for small apartments where the bike has to disappear into a cupboard between workouts.
The folding X-frame is the headline feature, letting the bike collapse for storage behind a door, and at just 16.5 kg it is the lightest machine here to move and fold away one-handed.
A silent magnetic resistance system with eight levels covers easy spinning through to a firmer climb, while non-slip feet and a large padded seat keep it steady and comfortable. An LCD tracks time, speed, distance and calories, and there is a built-in phone holder.
It suits riders 155 to 185 cm tall and up to 100 kg, with four seat-height levels to dial in a comfortable position.
Trade-offs: the lighter folding frame is less rock-solid than a fixed spin bike for hard standing sprints, the magnetic system tops out gentler than a heavy flywheel, and it is currently out of stock in Christchurch though available elsewhere in the country.
Pros
- Folds flat for easy storage
- Lightest unit here at 16.5 kg
- Silent magnetic resistance with 8 levels
- Padded seat and built-in phone holder
Cons
- Less solid than a fixed spin bike in sprints
- Currently out of stock in Christchurch
Key specs: model PR6044; magnetic resistance, 8 levels; folding steel X-frame; 16.5 kg; 4 seat-height levels; suits 155-185 cm, max user 100 kg; LCD; phone holder.
7. X-Bike Folding Exercise Bike – Best for Full-Body Workouts
Best for full-body workouts: the X-Bike Folding Recumbent Exercise Bike With Rope adds a backrest, arm supports and pull ropes, so it works the upper body as well as the legs and suits comfort-focused or rehab cycling.
This folding X-frame bike pairs a recumbent-style backrest and arm supports with resistance pull ropes for the arms and shoulders, turning a leg session into a fuller-body workout. The extra-wide, thickly cushioned PU saddle is built for longer, comfortable rides.
A silent magnetic system with eight resistance levels keeps it quiet enough for any time of day, non-slip feet add stability, and an LCD monitor tracks speed, time, distance, calories and pulse. At 20 kg it still folds away for storage.
It suits riders 155 to 185 cm and up to 100 kg, with easy pull-pin and screw adjustments to set the seat.
Trade-offs: the rope and backrest add bulk compared with the plain folding model, the 100 kg limit is modest, and the relaxed recumbent-style position is less aggressive than a true spin bike for high-intensity training.
Pros
- Pull ropes and arm supports add an upper-body workout
- Recumbent backrest and wide cushioned seat for comfort
- Silent magnetic resistance with 8 levels
- Still folds away despite the extra features
Cons
- Bulkier than the plain folding model
- Relaxed position is less intense than a spin bike
Key specs: model PR6045; magnetic resistance, 8 levels; folding steel X-frame; recumbent backrest, arm supports and resistance ropes; 20 kg; suits 155-185 cm, max user 100 kg; LCD.
8. Genki 4-in-1 Foldable Exercise Bike – Best Convertible
Best convertible: the Genki 4in1 Foldable Exercise Bike switches between upright and recumbent setups and folds flat, so one machine covers several training styles in a small footprint.
The 4-in-1 design is the draw, letting riders move between an upright spin position and a more reclined recumbent posture, then fold the bike away when the session is over. Magnetic resistance keeps each mode quiet and low-maintenance.
An adjustable resistance dial and an LCD screen tracking time, speed, distance and calories cover the essentials, and the foldable frame suits apartments and shared rooms. It is the newest pick here, listed without reviews yet on Bestdeals.
Because it converts between positions, it is a flexible option for households where one person wants an upright workout and another prefers a gentler, supported ride.
Trade-offs: as a do-everything folding bike it is a jack of all trades rather than a dedicated spin machine, the convertible joints add setup steps, and the magnetic resistance is gentler than a heavy-flywheel bike for serious sprint work.
Pros
- Converts between upright and recumbent
- Folds flat for storage
- Quiet magnetic resistance
- Adjustable resistance and LCD tracking
Cons
- Jack of all trades rather than a dedicated spin bike
- No owner reviews yet
Key specs: magnetic resistance; 4-in-1 upright and recumbent design; foldable frame; adjustable resistance; LCD screen; Bestdeals product code 73986.
9. Genki Fitness Spin Bike – Best Connected Spin Bike
Best connected spin bike: the Genki Fitness Spin Bike adds Bluetooth on top of a quiet belt-drive setup, so riders can pair a fitness app and follow guided classes, and it is the most-reviewed bike in this guide.
It is the popularity pick, carrying around 30 reviews on Bestdeals, the most of any bike here, which points to a proven everyday spin bike. A belt-drive system with adjustable resistance keeps the ride smooth and quiet.
Bluetooth connectivity is the standout feature, letting the bike talk to a fitness app on a phone or tablet for tracking and classes, while the LCD monitor covers the on-bike basics. The adjustable seat and handlebars let it fit a range of riders.
For people who like a structured, app-guided session rather than free riding, the connectivity is what sets this one apart from the other belt-drive spin bikes in the guide.
Trade-offs: it is a fixed-frame bike with no folding option, so it needs a dedicated space, assembly is required, and the app pairing relies on a third-party fitness app rather than a built-in touchscreen.
Pros
- Bluetooth pairs with fitness apps
- Most-reviewed bike here, around 30 reviews
- Quiet belt drive with adjustable resistance
- Adjustable seat and handlebars
Cons
- Fixed frame, does not fold
- Relies on a third-party app, no built-in screen
Key specs: belt-drive spin bike; adjustable resistance; Bluetooth connectivity; LCD monitor; adjustable seat and handlebars; Bestdeals product code 38031.
How to choose an exercise bike
Pick the right type. Spin bikes copy a road bike for high-intensity training and take up little floor space; upright bikes are a comfortable all-rounder; recumbent bikes add a backrest and suit sore backs, joints or rehab. Folding and convertible models trade some stability for easy storage.
Weigh the flywheel. On a spin bike a heavier flywheel carries more momentum, so the pedal stroke feels smoother. An 18 kg flywheel gives a planted, road-like ride, while an 11 kg flywheel is lighter and cheaper but can feel busier at high cadence.
Check resistance and noise. Magnetic resistance is near-silent because nothing touches the flywheel, which is ideal for apartments. Belt-drive spin bikes are quiet too and feel more like real cycling. Both beat old friction-and-chain designs for noise.
Match the bike to the rider and the room. Check the maximum user weight and height, and allow roughly a 2 m by 1.2 m clear area to ride safely. A recovery routine helps too, so it is worth pairing training with the massage guns guide, the elliptical trainers guide for a low-impact alternative, and the fitness trackers guide to keep an eye on progress.
Verdict
For committed home cyclists the 18kg flywheel spin bike is the best all-rounder, with the heaviest flywheel and highest user-weight limit here for the smoothest ride. Choose the magnetic Genki for the quietest spin, the orange or grey 11 kg bikes on a budget, the folding X-Bike for small spaces, the recumbent X-Bike with rope for comfort and upper-body work, the Genki 4-in-1 for flexibility, and the Bluetooth Genki Fitness Spin Bike for app-guided classes.
FAQs
Which type of exercise bike is best for home use?
It depends on the goal. Spin bikes suit high-intensity, road-style training in a small footprint. Upright bikes are a comfortable all-rounder for general fitness. Recumbent bikes add back support and suit joint issues or rehab. Folding bikes are best when storage space is tight.
Does flywheel weight matter on a spin bike?
Yes. A heavier flywheel carries more momentum, so the pedal stroke is smoother and more stable, which is easier on the joints. An 18 kg flywheel feels planted and road-like, while an 11 kg flywheel is lighter and more affordable but can feel busier at very high speeds.
Are magnetic exercise bikes quieter than belt-drive ones?
Both are quiet, but magnetic bikes are the quietest because the magnets never touch the flywheel, so they run almost silently with little to wear out. Belt-drive spin bikes are also quiet and feel closer to real cycling, and both are far quieter than old chain-and-friction bikes.
How much space does an exercise bike need?
Allow roughly a 2 m by 1.2 m clear area. Most bikes are about 1 m long and half a metre wide, but extra clearance is needed to get on and off safely and to move around the bike. Folding models pack down far smaller for storage between sessions.
Is 30 minutes a day on an exercise bike enough?
For most people, yes. A daily 30-minute ride at a moderate to vigorous pace supports heart health, endurance and weight management, in line with general guidance of about 150 minutes of activity a week. Adding intervals increases the benefit without needing more time.
Are budget exercise bikes worth it?
For home cardio, yes. A well-built belt-drive or magnetic bike with an adjustable seat, a usable flywheel and a clear user-weight limit delivers a smooth, quiet workout. The main compromises at lower prices are lighter flywheels, simpler consoles and flat-pack assembly rather than a poor ride.
