ASUNA 5100 Magnetic Belt Exercise Bike

Exercise bikes are a fantastic way to get fitter and healthier as they offer a low-impact, safe cardiovascular workout.   Cycling on an exercise bike is not only good for weight loss, but with regular activity you can decrease your blood pressure and improve your heart health.   The Asuna 5100 bike can be used for both easier and harder workouts, but it comes into its own when used for spinning or interval training.

As this bike is specifically designed for spinning workouts and interval training, the ASUNA 5100 Magnetic Bike is great for people who want to take their exercise regime to the next level.

Frame and Build

Sunny ASUNA 5100 Magnetic Exercise Bike

The ASUNA 5100 Magnetic bike is  a solid build and the frame is made of good quality commercial grade steel.  In fact, the only plastic parts on this bike are the belt guard and a few other protective components.  The bike is heavy and sturdy enough not to slip or move when doing a high intensity workout.

Feels like a high quality gym spin bike

The maximum user weight is 300lbs.

The lowest seat setting: 28.5″ (saddle to pedal) with the highest seat setting being 40″ (saddle to pedal).  Users who are 6’4″ have reported that is bike is comfortable for them to use.

The bike is a sleek design and will fit easily into the corner of a room or a small space.   It certainly takes up much less room than other cardiovascular equipment such as a treadmill or a cross-trainer.

What makes the ASUNA 5100 Magnetic Exercise Bike different?

Flywheel

Sunny ASUNA 5100 Magnetic Exercise Bike

This stationary exercise bike is built with a 37.5lb flywheel.   While this is not the heaviest flywheel on the market, it is perimeter weighted which means it will provide a natural and smooth consistent cycling motion and a near silent operation.

The magnetic resistance works by turning the knob conveniently located below the handlebars.  When the knob is turned clockwise or anti-clockwise, more or less magnets will pass over the flywheel subsequently increasing or decreasing drag.  The advantage of this system is that there are no clunky gear changes or brake pads to wear out and that resistance can be changed subtlety and quickly to suit all fitness levels and workouts.  High resistances will provide a gives a truly heart pounding workout!

Pedals

The pedal provided are reversible so you can use SPD clips or wear trainers with support from a foot cage.  With a specially coated non-slip surface, foot slippage is minimized and comfort and safety prioritized.

Comfort

5100-3-180x180Comfort is a major factor when choosing a new exercise product.  We love that the ASUNA 5100 Magnetic Bike comes with a fully adjustable seat.  This will be adjusted not only up and down but forward and aft, allowing users to find the most comfortable seating position throughout their workout. The handlebars are also fully adjustable and are covered by rubber foam.   The ergonomic design of the handlebar allow multiple positioning options for a truly comfortable and natural ride.

There are 2 conveniently placed water bottle holders (bottles not provided).

Assembly

Sunny ASUNA 5100 Magnetic Exercise BikeThe ASUNA 5100 Magetic Bike comes pre-assembled.  The main part of the bike (e.g. the frame, flywheel, resistance mechanism and belt) are already assembled when delivered for your convenience.  All you need to do is attached the pedals, seat, handlebars and the bases.  This takes roughly 20 minutes with minimal inconvenience.

The ASUNA 5100 Magnetic Bike has transport wheels attached to the bike so it can simply be tilted and rolled into a suitable location.

What are Others Saying about the Asuna 5100?

Sunny ASUNA 5100 Magnetic Exercise Bike

This checks all the boxes and glides smoothly underneath me

Easy to assemble and super smooth sturdy ride

Any Negatives?

Due to the shipping weight of the bike (around 110lbs) it can be difficult to move into flats and apartments.

The bike seat is not the most comfortable saddle as it is designed to replicate a road bike and also be used as a spin bike (e.g. peddling in a standing position some of the time).  For extra comfort, you may wish to purchase a gel saddle like this one from Schwinn:

There is no in-built console with this ASUNA bike 5100 which means it can be difficult to monitor time, distance, calories burned etc.   However, with the growing popularity of wearable technology, such as Fitbits, that can monitor individual activity levels 24/7, this shouldn’t be an issue with most exercisers.

ASUNA 5100 Magnetic Belt Drive Commercial Indoor Cycling Bike Silver Review Summary:

This is the one of the best indoor/spinning bikes for home use that we've seen. With its exceptional build quality, it really feels like a gym bike.

If you are looking for a great way to work out in the comfort of your own home, then this is the bike for you.
