HARISON B1850 Indoor Bike – Affordable and Practical!

The HARISON B1850 Indoor Bike is an affordable and practical spin bike for home use. Whether you are a beginner or advanced bike enthusiast, the B1850 indoor bike will help you get the best workout possible. No matter if your goal is strength training or weight loss, the B1850 is a beautiful partner!

The HARISON Pro Indoor Cycling Bike has a friction resistance system that is infinite. The felt pad faces down next to the flywheel and connects to the tension knob on the mainframe tubing. By turning the knob clockwise, the resistance increases. There aren’t any settings marked on the knob. You can keep turning the knob until it becomes too hard to pedal.

The B1850 comes with a multi-functional digital monitor. The LCD monitors time, speed, distance, calorie, RPM, ODO, scan, pulse. The workout metrics displayed are time, speed, distance, calories burned, RPM, Odometer, and heart rate.

The saddle is professionally designed to reduce the friction between your legs and the seat while you are riding. The handlebars and seat can be adjusted vertically and horizontally to accommodate your body’s shape and riding posture better. These basic features also make it possible for you to sit or stand while riding, just as you can on a road bike.

B1850 Frame construction

The HARISON B1850 indoor cycling trainer features a heavy-duty 48 mm steel frame. It’s solid enough to support users up to 280 lbs (127 kg), which is not bad for a home use trainer. Most of the tubes in the bike’s construction have a rectangular shape, except for the front fork tubes, which are oval and the round base bars.

Also, all the steel components come with a corrosion-resistant paint finish. The primary colors used are white for the core frame and black for the seat and handlebar tubes. Of course, the frame features several stickers with the “HARISON” logo.

The fully assembled bike is slightly larger than other models. It is 47″ (119 cm) long, and approximately 20″ (51 cm) wide. Therefore, you will need a usage area for it of at least 70″ x 60″ (177 x 152 cm). In terms of weight, the bike isn’t as heavy as other models, mainly because it has a lighter flywheel.

However, it still weighs approximately 68 lbs (30.8 kg), which is twice the weight of the average road bike. Plus, it has a low center of gravity; so, it provides excellent stability. The bike’s rear base bar features two octagonal caps, which can rotate, allowing you to perfectly level the bike on any floor. It is recommended, though, to place it and use it on a mat. If you’re wondering, this HARISON exercise bike doesn’t fold. However, its front base integrates two transport wheels which facilitate its relocation.

An essential element that other spin bikes do not have is the step-up element that connects the seat tube with the mainframe oblique tube. This small horizontal bar is precision-welded to its two adjacent tubes providing superior sturdiness.

It also has a top cover to prevent the wear of its paint in case of repeated use. This gives you the possibility to quickly step on the bike whenever you want to commence your workout or perform specific spin workouts that require you to mount and dismount repeatedly.

Seat and handlebars

The HARISON B1850 comes with a spin seat. Now, as a general idea, these seats are not made for super comfort. The saddle is very slim at the front but does have a layer of padding which is thicker in its rear area. It also has a longitudinal groove, which is meant to improve breathability during seated workouts.

The bike’s saddle has a collar-based standard connection system to the slider. Therefore, in case you don’t find it too comfortable, compatible options for it are widely available. Its comfort can be improved by a gel seat cushion, though.

The seat assembly offers 4-way adjustability. It can move up, down, forward, and backward. Its upright post features several adjustment holes, while the horizontal slider provides a few extra inches of front-back adjustment.

Therefore, the bike can accommodate users between 5’0″ and 6’4″ (153 – 193 cm) with no problem. Also, the seat assembly is designed to hold users up to 280 lbs (127 kg) with no problem.

The HARISON B1850 comes with a multi-grip handlebar. It features two extended side grips, and a loop aero bar in the middle. The aero bar also integrates a device holder on which you can place your smartphone or tablet.

A layer of high-density foam material covers the whole handlebar to provide a secure grip. Also, its side grips integrate metallic pulse sensors, while the included exercise meter can monitor your pulse. Some of the more expensive spin bikes do not have a pulse reading function, so this is a plus.

B1850 Resistance System

The HARISON B1850 indoor cycling bike is equipped with a mechanical, magnetic resistance system. This means it doesn’t offer automatic resistance control and does not require connection to an external power source.

The bike’s resistance system consists of a felt pad that is attached to the tension knob on top of the bike’s main tube. If you turn the knob clockwise, the brake pad applies more friction to the flywheel, which leads to an increased pedaling difficulty.

The brake system does not have pre-determined settings. You tighten the brake on the flywheel until you get the desired pedal tension. The tension knob also has the emergency brake function; you can press it down to instantly stop the wheel from spinning.

This exercise bike comes with a slightly lighter flywheel than other bikes. It weighs only 29 lbs (13 kg), while for most other spin bikes, the flywheel weight starts at 40 lbs (18 kg).

But the flywheel features a perimeter-weighted structure. This leads to a very consistent pedaling motion even with a low friction factor, which is excellent for spin workouts.

The flywheel allows pedaling in reverse. However, coasting is not possible on this bike. The pedals continue to spin for as long as the wheel is spinning. Thus, when pedaling in reverse, you will get the same resistance as when pedaling forward.

B1850 Drive System

The bike’s drivetrain involves a heavy-duty belt. As a general idea, a belt transmission comes with several advantages. For example, you won’t ever have to lubricate it, it generates less vibration than a chain drive, and the pedaling motion is very smooth and quiet.

Last but not least, this HARISON exercise bike has a solid crankset. It features steel crank arms that can hold users up to 280 lbs (127 kg) in a complete standing up position. The pedals are made of durable nylon material but do have a steel core. They have toe cages but do not have SPD clips for spin shoes. Their threads are 9/16″, though, so that you can find replacements for them in any bike shop.

The LCD included with the HARISON B1850 bike is slightly better than a fundamental unit. That’s because it also shows RPM and pulse, along with the primary readings – time, distance, total distance (odometer), speed, and calories burned.

Speed and distance are in imperial units (you cannot set to metric). Also, for the pulse reading function, you will have to use the integrated sensors. The console is not telemetric, so it cannot read your pulse through a chest belt transmitter.

The console is straightforward to use. It only has one button. By pressing this button repeatedly, you can scroll through the metrics and select the one that you want to view.

It also has a Scan function; so, when the Scan function is selected, the meter rotates all the values showing each one for several seconds. Also, by pressing and holding the button for a few seconds, you can clear all the metrics to zero.

The console does not have any preset programs or online connectivity. It has a standard LCD and requires one AA battery as its power source. It starts up when you press its button or when you begin pedaling. Furthermore, it also has a sleep mode to which it will enter if there is no input on the bike for a few minutes.

B1850 Assembly and Maintenance

The bike’s drive and resistance elements (flywheel, crank, belt, and brake) are already attached to the mainframe. For assembly, you’ll have to connect the base bars, the pedals, the seat post and saddle, the handlebar post and handlebars, and the console.

This shouldn’t take more than one hour — a set of necessary tools for the task (is included). Also, the process is quite straightforward, and the manual provides clear step-by-step assembly instructions.

Since the bike has a belt drive system, its transmission doesn’t need lubrication. Therefore, in terms of maintenance, you only need to periodically check for loose bolts and parts, and re-tighten them if required.

  1. I may consider getting this as a holiday gift for myself. I’ve had an old exercise bike for the last six years, and the chains aren’t working anymore, so I think this might be the perfect replacement. What sealed the deal for me was the fact that you can adjust the seat of the bike to your liking. I have never had anything like that. I’m bookmarking this article for the next time I get paid so I can order this. 

  2. Hello Robert, thank you for taking the time to put this post together and for sharing these remarkable insights regarding Harison B1850 indoor bike.
