From beginners to intermediate and elite cyclists, this Sunny ASUNA Minotaur 7150 can satisfy all workout needs. The magnetic resistance level and the belt drive mechanism provide a silent and maintenance-free workout — the tension knob functions for resistance adjustment and emergency brake.
The 33-pound aluminum and high alloy steel flywheel provide a high inertia exercise for users up to 330 pounds. The Sunny ASUNA 7150 cycle features front-drive design, which means the drive mechanism is located directly under the sweat zone. However, you don’t need to worry about sweat getting into the drive system because there is a durable guard that covers all around the wheel.
The handlebars offer multi cycling grips and also two water bottle holders to keep you hydrated. There is also another water bottle holder on the side of the frame. The racing seat is very comfortable. There are parallel seat rails that run along the underside leaving the middle hallow for extra comfort and adaptability. Pedals are dual-sided with spd cleats and toe cages.
The materials on the posts of the seat and handlebars are high-grade aluminum, which reduces the weight of these parts for more effortless adjustment. All the positions are numbered/marked. So, let’s say someone else uses the bike and change the seat adjustment: it’s going to be easy for you to adjust the seatback the way it was.

7150 Frame construction
The Sunny ASUNA Minotaur 7150 features a massive structure, with a one-piece, all-steel frame, with precision machined welding points. The only frame parts that attach to the mainframe via bolts are the bike’s bases.
The bike can withstand users up to 330 lbs (150 kg). Therefore, considering its bulky frame and the thick bar of the seat, it should be able to support even heavier users. However, the 330 lbs are its specified maximum user weight capacity.
Most of the bike’s frame is powder coated with industrial-grade corrosion-resistant and scratch-resistant paint. The only color available for this bike is black (at least for the moment). The ASUNA logo is in blue, while the Minotaur name is white. The seat and handlebar posts and sliders feature a chrome finish, also corrosion-resistant.
The ASUNA Minotaur 7150 has a footprint a bit larger than other indoor cycling bikes. With the frame fully assembled, it is 57″ (145 cm) long, and 27.2 (69 cm) wide. This larger footprint, along with its 132.8 lbs (~60 kg) weight, plays an essential role in its overall stability.
Plus, both base tubes feature adjustable stabilizers with rubber caps. Therefore, you can be sure that it won’t rock or wobble even if you engage in some of the hardest spin workouts.
Seat and handlebars
The seat supplied with the ASUNA Minotaur 7150 is a spin bike seat featuring a large longitudinal groove to promote healthy blood circulation during seated workouts. However, like most spin bike seats, it’s not designed for comfort. Although well cushioned, it still is a slim seat, and for a user new to spinning may seem uncomfortable.
But it has a standard design, and compatible replacements are widely available. Besides, you can always improve its comfort with a gel cover.
The seat can be adjusted up, down, back, and forth. It’s adjustment span is 10″ (25.4 cm), from 28.5″ (72.4 cm) to 38.5″ (98 cm). Differently put, the bike can accommodate users between 5’0″ and 6’7″ (153 – 201 cm).
The handlebar features a multi-grip design, with integrated aero bars and bottle holders. Just as the seat, it is 4-way adjustable, offering an adjustment span of several inches vertically and horizontally. The whole handlebar is padded with high-density foam to provide a secure, comfortable grip.
Both the seat and the handlebar feature large, adjustable levers, easy to grip and turn. Thus, setting up the bike for your size shouldn’t take up more than one minute.
Like most other commercial spin bikes, the ASUNA Minotaur 7150 uses a manual friction resistance system. It consists of a leather pad attached to the tension dial atop the central tube of the frame.
The brake pad is concealed by the plastic cover, which also shields the top part of the flywheel.
To add resistance, you have to turn the dial clockwise; this enables the brake pad to apply more friction onto the flywheel, resulting in higher pedal resistance.
There aren’t any resistance settings or “clicks” specified on the resistance knob. You have to tighten it until you obtain the desired resistance. The knob also acts as an emergency brake; you can push it down to immediately stop the flywheel.
The ASUNA 7150 features a 33 lbs (15 kg) aluminum and steel alloy flywheel. This flywheel is a bit lighter than for other Sunny Health & Fitness exercise bikes, such as the SF-B901B, for example.
But it can generate a very consistent momentum. It’s also perimeter-weighted, which means that the pedaling motion is very smooth and steady.
The flywheel is bi-directional. In other words, the bike gives you the possibility to pedal in reverse. When pedaling in reverse, it will retain its tension, though.
The bike uses a belt-drive, powered by a heavy-duty belt, designed to last for many years of use. This belt drive comes with two main advantages. One, it quieter than a chain; in fact, the bike generates very little noise when in use. And second, it doesn’t require any maintenance.
Since it’s a commercial-grade bike, it comes with a very solid crankset with steel crank arms, which can hold the entire weight of the rider with no problem. Also, the pedals supplied with the bike are dual-sided. They feature SPD elements for spin shoes on one side and toe cages with straps on the other.
The bike’s Q-Factor (spacing between the pedals) is 140 mm. This is a pretty narrow Q-Factor, offering superior biomechanics that improve comfort and optimal efficiency.
Differently put, your feet are positioned on the pedals naturally, without any extra lateral stress on the ankles or knees. This results in longer workouts and a lower chance of developing any post-workout joint pain.
7150 Assembly and Maintenance
The ASUNA Minotaur exercise bike comes partially assembled. The flywheel, the belt, crankset, resistance pad, and their covers are already attached to the frame. Therefore, you will only have to connect the two bases, the seat, the handlebars, and the pedals.
This shouldn’t take longer than 20 min. All the tools required for the assembly are (included). Also, the supplied manual offers all the necessary assembly instructions.
Since the bike doesn’t have a chain drive, its transmission doesn’t require any maintenance. Therefore, you only have to check for loose bolts and parts from time to time. Also, in case the resistance pads develop a burnt scent due to friction, lubricating them with a little bit of silicone lubricant is an excellent solution.
