345 Frame Construction

The Stamina 345 upright bike features a steel frame with a small footprint, which is great for apartment use. With all the parts assembled, the bike is approx. 37.4″ (95 cm) long and 19.7″ (50 cm) wide, while its handlebars reach approx. 50.1″ (127 cm) above floor level.

Therefore, it is advisable to allow at least two feet of clearance all around the bike for easy access and safe usage.

The bike is not super heavy, weighing approx—72 lbs (32.6 kg). Therefore, two people should carry the boxed bike. However, one person can assemble it. Once completed, the bike is easy to move as its front base stabilizer has a set of transport wheels. Also, the rear stabilizer features polygonal caps that rotate and can act as levelers.

The bike’s frame combines oval, rectangular, and cylindrical tubes in its construction for improved sturdiness and aesthetics. In addition, all the steel parts are double-coated with a black corrosion-resistant and chip-resistant paint finish. The only exception is the chrome-plated seat post.

The main body of the bike, with all the drive and resistance elements, has a set of extensive, durable thermoplastic material large guards. The small guard at the base of the front upright bar of the machine also integrates a bottle holder.

Seat and handlebar

The Stamina 345 upright bike includes a pretty standard saddle. Its durable internal nylon shell has a top cover made of a high-density gem, and the saddle is larger than the average bike seat. In addition, it has a bit of contouring for improved breathability.

The bike’s seat is four-way adjustable (up, down, front, back). In addition, its vertical post offers seven adjustment positions, while its horizontal slider adds a few extra inches of front-to-back adjustment. Therefore, the bike should be able to accommodate users between 5’0″ and 6’2″ (153 – 188 cm) with no problem, allowing a complete leg extension.

However, taller persons should still be able to use this bike, but they may not benefit from a complete range of motion. In addition, the seat has a maximum user weight limit of 250 lbs (113.3 kg).

The bike includes a multi-grip handlebar. Its side grips are relatively long and have an inner curvature at the front. They also have a layer of PVC foam material for improved contact. Furthermore, they integrate HR pulse sensors, and the fitness monitor can track your pulse.

The handlebar is angle-adjustable. It attaches to the front post of the bike with a small knob that allows you to easily untighten it, adjust its angle, and retighten it at the desired angle. However, the vertical post does not offer any adjustability.

345 Resistance system

Stamina 345 Upright Bike

The Stamina 345 upright bike has a motorized magnetic resistance system. Therefore, you must connect it to an external power source to power up the fitness monitor and adjust the resistance. A standard US-type 3-prong adapter comes with the bike; its output is 9V / 500 mA.

The bike’s resistance system consists of a magnetic brake and a small servo motor that connects it to the fitness monitor. Thus, when you adjust the resistance from the monitor or when one of the programs automatically adjusts the resistance, the motor moves the brake closer or farther from the flywheel, which increases or decreases the resistance.

The main advantage of a magnetic brake is that the tension elements do not touch. Thus, the pedaling motion is smooth, with zero drag and whisper-quiet. In addition, the wear-and-tear of the brake is virtually zero.

The bike offers 16 levels of resistance. The 1-3 difficulty levels offer light resistance, which is great for recovery training or a light warm-up. The 7-10 levels are great for toning leg muscles and improving strength and stamina. And finally, the 10-16 levels allow you to achieve a higher calorie burn and an increased cardiovascular rate in a shorter time.

Drive system

The internal flywheel of the Stamina 345 upright bike is perimeter-weighted. This construction improves inertia and adds stability to the pedaling motion.

Its exact weight is not specified, but considering that the bike’s overall weight is less than 75 lbs (34 kg), the flywheel probably doesn’t weigh more than 20 lbs (9 kg). The flywheel is also bi-directional, so you can pedal in reverse if you want.

The bike has a dual belt drive system. One belt connects the crank pulley to an intermediary smaller pulley, while the second belt connects the flywheel to the intermediary pulley. This type of dual belt drive also improves motion stability and adds a bit of difficulty to the ride.

The integrated belts have a poly-v design for improved traction. In addition, since no chain is involved, the unit’s drive system does not require periodic lubrication.

The bike features a set of large crank arms concealed by two large thermoplastic material discs. The pedals are plastic-made as well. In addition, they have a textured surface and adjustable straps for improved foot stability. Furthermore, they are also weighted, so they always self-level if you remove your feet from them.

Even though the bike has a durable crank assembly, the bike is not made for pedaling while standing up or for spin workouts. Even if it may hold you with no problem, these workouts are not advisable as they may damage the internal parts and result in much higher wear and tear for the pedals.

345 Fitness monitor

The Stamina 345 upright bike has a mid-range fitness monitor with a multi-window LCD with a blue LED backlight for improved readability. It tracks time, speed, RPM, distance, calories, watts, and pulse.

The speed and distance are in Imperial units (mph and miles). The pulse reading function is hand-grip only. You must hold on to the sensors integrated into the seat handlebars for the monitor to read your pulse. Unfortunately, the monitor cannot read the pulse from a wireless transmitter.

The monitor is incompatible with any fitness apps and does not have Bluetooth connectivity. However, it has plenty of programs to keep you motivated. To begin with, it has a Manual Mode which allows you to adjust the resistance as you like during the workout.

The following 12 programs are preset. These adjust the resistance automatically. They have different layouts and cover various types of workouts. There’s also a Watt Control program. And finally, there are four heart rate programs, three preset for 55%, 75%, and 90% heart rate, while the fourth is custom.

The monitor offers target-setting functions for time, distance, calories, and watts. If you select a time, distance, and calories target, it will count down from the specified value until you reach zero and complete your current goal. The watt target is a bit different. If you choose a watt target, the monitor will automatically adjust the resistance to keep you close to the selected target watt.

A Body Fat function and a Recovery function are also available. These have quick access keys on the monitor. The Body Fat function calculates your Body Mass Index based on your data input (age, gender, height, weight). The Recovery function counts your pulse at the end of the workout and determines your fitness level, rating it between F1 – excellent and F6 – poor.

Assembly and Maintenance

Stamina 345 Upright Bike

The base body of the bike comes pre-assembled. The drive and resistance elements are already in place, attached to the mainframe, and concealed by plastic guards. You only need to connect the two base stabilizers, the seat post, the seat, the handlebar post, the handlebar, the fitness monitor, and the pedals.

Consequently, this may take more than an hour of your time, but the process is relatively simple. Also, the manual provides clear assembly instructions, and all its tools come included.

The bike’s internal parts are pre-lubricated from the factory and should not require maintenance for a long time. Therefore, in terms of care, you only have to keep the bike clean, wipe the sweat that may fall onto the frame at the end of the workout, and periodically check for loose bolts and parts and retighten them as required.

  1. The Stamina 345 upright bike provides a lot of exciting and helpful feedback. On top of this is the magnetic brake, whose tension elements do not touch for a smooth and quiet ride. And having a brake with no wear and tear shows you need not worry about its maintenance.

    • Hi there; thanks for stopping by and sharing your thoughts with us. Please let me know if I may further assist you with exercise equipment. I’m always happy to help.

      Kind regards, Robert

  2. This is probably one of the most thorough reviews of any exercise equipment I have seen! The questions I had regarding size, weight, and connectivity were laid out in easy to read format. The pros seem to outweigh the cons considering everything from purchase to setup is pretty straightforward; however, I am sure that the connectivity issue would deter many people from purchasing. Do you think they will upgrade with better connectivity in the future?

    • Hi Kelly, thanks for stopping by and sharing your thoughts with us. I don’t think Stamina will upgrade to monitor to have Bluetooth connectivity any time soon.

      However, the Sunny SF-B220045 SMART Upright Bike has Bluetooth connectivity and is comparable to the Stamina bike. Both bikes are upright. If you are interested in any other type of bike, please let me know, and I’d be happy to help you find what you are looking for.

      Kind regards, Robert

  3. This is exactly the bike I think I’d enjoy for several reasons. 

    It has several pros that seem to fit my needs, including a large padded seat, Adjustable handlebars, and a bottle holder for when I get thirsty from pedaling so much.

    Compared to other reviews on exercise equipment you have done, this one has caught my attention the most to help aid in my exercise routines. So I will keep it on my radar. 

    Thanks for the article.

    • Hi Jeremy, thanks for stopping by and sharing your thoughts with us. Please let me know if I may further assist you with exercise equipment. I’m always happy to help.
