Solid Build - but big drawback + resistance HACK

Solid Build - but big drawback + resistance HACK
Opinions echo much of the others here:My first at-home spin bike. Previously rode in the gym or studios. Relatively happy so far and does thejob and is a clean-looking addition to the house.Assembly - well packaged, straightforward, not too many steps, all tools providedBuild quality - well done, sturdy, stable and appropriate for my 6' 230lbs, slight wobble in handlebars. Purely quiet which is huge plus, and still feels like a bike. The drop bars on the handles is a major reason I bought this. Seat is plush and comfy with plenty of horizontal and vertical range. Tension knob takes a ton of turns to change the level. Comes with an ipad shelf and water bottle holder, which I chose not to install.Computer - sure I guess it tracks some things, but not really useful, and no RPMs, which is the main one for spin. Upcoming buy is a cadence sensor.Resistance - perplexingly falls short here. Out of the box, the upper end isn't nearly difficult enough. About a level 6 or 7 max. But I was able to tune the resistance by removing the plastic panel, and moving the magnets closer to the wheel (see photo) by experimenting with the tension knob bolt. Discarded the lower bolt as it interferes with the range. Gets it to a more acceptable top end. Next step down the road is to adjust the flywheel closer to the magnets via the axle bolts and hopefully up tension some more.A real improvement on this bike model would be to lengthen the tension knob main bolt to allow greater range and thus increasing tension. And wider threads as it would reduce the turns required to change the resistance. Some attention to this resistance issue would make this an outstanding bike.Workout - yes you can still get a good workout on this bike especially with the suggestions above. If tension not enough, ride faster or longer. I tap into Youtube guided rides and I get the sweat on.Good luck and good riding.

Received the product and I was shocked by the good quality and low price. Seems well made, solid and sturdy. The bike has some some weight to it and is super quiet. It is very simple to put together and it comes with tools for assembly, however, you will need a sharp box cutter knife or wire cutter to cutoff the plastic ties that hold the parts together. Unlike some other products on Amazon, the instructions are in English that is easy to understand and actually make sense. The bike is super quiet, has a simple onboard computer, and is smooth to operate. The handle bar and seat height is adjustable and so is the wheel tension. The seat can be moved closer or further from the handle bar. If you are a smaller person under 5' tall, you may have an issue with the maximum seat setting not being able to adjust it close enough to the handle bar. If this is the case, you may have to look for a handle bar extension. I have not used it long enough to comment on longevity. If I have any issues, I will update my comments. Very happy with this buy so far and highly recommend it.

Shipping:
- The bike arrived as scheduled even during a few heavy days of snow fall and a notice it might be delayed.
- The bike and all it's parts are packaged tightly and protected.

Assembly:
- It took about 40 minutes to build the bike
- instructions are straight forward and easy to understand and all the tools needed are included with the bike.
- Bike is a nice size and does not take to much room, the bike fits on a small workout towel that you would get from a goodlife or other gym. ( see photo)
- they were nice enough to send me a gift of a mat to place under the bike.

Riding The Bike:
- The bike makes almost no noise and is smooth when pedaling
- Magnetic resistance
- feels sturdy and balanced
- easy to roll away to store if you need to
- the red knob to add resistance while pedaling makes a slight squeaking noise when I turn to add resistance or reduce it, this may be because it's new and the metal thread going against the metal handle.
- Handlebars do seem to slightly wobble from the post going into the bike, this may be because I have it on the highest setting for my height so not much pole inside the bike to help it from shifting. It does not impact my riding at all or make it feel unsafe.
- the seat is comfortable

Riders:
- I'm 6"1 220 lbs and the bike fits just perfect for leg length even standing up on the pedals
- My wife is 5"7 140 lbs and the bike was easy to adjust to her level and she enjoys it
- Bike is in a basement with ceiling height of 6" 2, I'm able to ride seated and standing with just a slight bend forward so my head clears the ceiling.

Pros:
- Very easy to assemble
- Smooth ride
- Provides a great workout
- Does not take up a ton of space
- able to be used/set up for multiple people

Cons:
- Water bottle, laptop mount, workout computer feel cheap compared to the rest of the bike
- Laptop mount makes it awkward to grab the handles bars (no leaning on them or close gripping) we removed it from the bike.
- workout computer, helpful but moved when riding, I use an apple watch so again we removed this as it's not needed.
- Slight squeaking when adjusting the resistance (but i believe just because it was new on the first few rides with the metal handle and thread. (it is not the magnet making the nose just the red knob)

Overall:
I'm very happy with this bike and it is exactly what I wanted, for the price I feel like I got the value for the bike. the small cons of the attachments feeling cheap or in the way are an easy to remove. I would recommended this bike and am enjoying it very much.

Colour Name: Magnetic ModelVerified Purchase
Build quality for all metal parts seemed well made/solid. Plastic on the other hand, not at all. The screw that is used to screw in the pad where we can put a phone or tablet didnt fit the hole. The hole was too wide for the screw so it was just loose. I used another screw that i had left over from something else and i was lucky enough that it fit almost perfectly. Just a little too long so i cut it to make it flush.

The plastic rubbery part of the foot holders came in already screwed in. I wear size 14 so my shoes didnt fit in. Needed to take those off but the product didnt come with a wrench that fit that specific part. Keep in mind that this is a very minor detail since most people dont wear 14's and have wrench kits at home with one that fits this piece. After which i just put the wrench on the inside and used the screw-driver/allen key combo that came with the bike and removed the parts. Im just writing in for those few who dont have those tools at home and will have to buy one with the correct size if they wish to remove those parts like i did.

The part that is used as a holder to secure the screen in place was the weakest link by far. The screw that goes in to secure the screen to the handle's frame was a 1/10 quality. The hole for the screw was a little bit too tight. Luckily, its a cheap and maliable material so you can just clamp in with one hand and with enough grip strenght and force the screw in with the screw-driver/allen key tool that comes with it then screw it in the rest off the way. My only issue is trusting that the inside isnt too badly shredded that it get looser and looser with time. I dont think it will but its another thing to keep in mind. if it happens in a few months or years ill just glue it in place.

This depends mostly on personal preference and body shape but for me the seat is WAY too firm. Its firm to the point that i get serious discomfort after 2 minutes sitting on it. A 25 $ seat cushion will fix this for me. A little context: i weight almost 300lbs and dont have a butt to fit this body type so the extra softness is a must. If you dont have this problem, than youll be all set with this seat alone.

While i started this review with negative after negative aspect, they're just minor issues that I personally had while assembling it. Considering i didnt see any other reviews that stated those same issues, i might have just been unlucky and got a dud.

The thing that matters the most for me which is safety and material strenght is much more than i expected so im happy about it. Dont think anything will break or fail on the bike anything soon even considering my weight and how hard i pedal on bikes.

So for the price, even with the little fixable issues that i had, id say this is more than worth a buy.

Ps: i put 4/5 for the ease of assembly but it still took less than 30 minutes for me to get it complete. It was easy, simple and quick to put everything in place. The missing star is just because of minor fitting problems that took maybe 5 to 10 minutes in total to get around.

I mountain bike and bought this to use when it's too cold or wet outside, part of the home gym I've been building out during the pandemic. First, loved the colors because I just happen to have the black/red theme going with my other weights, etc. But I've now given it a few rides and can report it's a really solid indoor bike for the price.

Pros:
- Super quiet and smooth
- Sturdy and solid, doesn't wiggle and move while riding
- Heavy for sturdiness, but not so heavy you can't easily move it around or into a storage spot
- Good instructions for easy assembly. Took about 30 minutes taking my time.
- iPad fits nicely in the tray, resting against the computer for a good angle. It's nice to bike along to a virtual trail ride video while blasting tunes on the gym stereo.

Cons:
- Like others have said, the little computer is nothing special. It works but is a bit hard to read.
- The pedal straps don't feel deep enough to me and I only wear a size 9. It's more comfortable to ride without using them. You can take them off or just ride using the other side of the pedals.

Tips and review rebuttals:
- Some people complained in reviews I read about pedals that fall off or a seat that wiggles and can't be tightened, or is uncomfortable. Now that I have the bike and assembled it, I can say pretty definitely that these are all operator/assembly error -- NOT the bike.
- The pedals are CLEARLY marked with warning tags that they are specific left/right, and thread opposite directions for each one. One goes on clockwise, the other counter-clockwise. If someone had problems they likely put them on backward and stripped the threads.
- The seat and instructions also have tags that clearly state to tighten both nuts at the same time when you mount the seat. Here's the trick: The bike comes with tools, including a little socket wrench. It's 13mm, but you need two wrenches to tighten the nuts at the same time. I have wrenches, so I just grabbed another 13mm and it tightened fine. If you don't have a specific 13mm, try an adjustable or at least find a pair of pliers to tighten both nuts at the same time per the directions.
- The seat has THREE ways to adjust it to fit your comfort. Up/down (height), front/back AND the angle or tilt. Many people may not know they can adjust the latter by loosening the same seat nuts as above and adjusting the pitch of the seat. That's in the instructions but people don't always read instructions. Instead they complain.

Overall, I'm very happy with this bike.

5.0 out of 5 stars Works well for my needs at an affordable price
Reviewed in the United States on February 22, 2023
Verified Purchase
I've had this now for about a week. The carton was slightly damaged, and the corner was ripped open. I was concerned that it may have been dropped. (I think it was). However, upon opening, the bike was SO WELL packaged that other than some cracked pieces of styrofoam, the bike was in perfect condition.

It's heavy. Needed my husband's help to move it around and out of the packaging. It came with all of it's fasteners and tools on a shrink wrapped cardboard which is a nice plus instead of bags. Zero chance of anything missing. While the tools were nice, I ended up using a ratchet and sockets, a t-handle allen wrench and a full size phillips screwdriver. This was totally my preference. The included tools will work just fine. I'm just impatient and had the tools handy. Assembly was easy and straightforward.

My husband & I both use this. I really like how easy it is to adjust the seat, seat height and handlebar height. We both have different fitness goals, so this adjustability is very important.

I don't like the toe grips, but that's just me. The seat is a little uncomfortable. Again, it could be just me. Both of these things I can replace. The electronics is a nice touch, but I have a few complaints:

1. If you can switch it to imperial from metric, I haven't figured out how. Not a deal breaker, because I know how to convert.

2. Because my husband & I both use this bike, I wish you could reset the odometer by a long long key press, but you can't. You have to pull the batteries from the back and then re-install.

3. The electronic monitor seems a bit wobbly.

All in all, we're pretty happy with this bike. It was affordable and gave us the features that we were looking for without paying for features we don't want.

4.0 out of 5 stars Smooth, quiet, basic exercise bike with few flaws
Reviewed in the United States on October 13, 2021

Overall, the price was right for this model with a medium weight flywheel and magnetic resistance. The closest model I can compare it to in the American market is the Schwinn IC3, although the IC3 uses fabric resistance, which can add a little noise.

The assembly directions are mostly clear and I was able to get it together myself in about 25 minutes. The most awkward was getting the crossfeet installed, since you have to bend all the way over and lift the bike up while screwing in the bolts. There's no quick way to do this, so perhaps get a friend to help you on this portion to keep your back intact. All necessary tools are included.

There's lots of adjustment available, which is nice. I'm 6' 1" and fit comfortably. I share this bike with my wife who is 5' 8" and she also can adjust it to fit nicely. My only complaint so far after about 5 hours of use is this: the handlebars can either be a little wider, or the device mount could be a little slimmer. I say this because my hands don't have enough flat surface to grip the bars. They are constantly pinched up on the side of the device mount. After about 45 minutes this gets pretty annoying. Using the higher up portion of the bars with the horns and heartbeat monitor just doesn't feel natural to me at this point. Maybe that will change.

When I say basic, it's true. The "computer" has a single button to scroll between a few measurements like distance, time, speed and a guess at how many calories you're burning. There's nothing here that works with any of your fitness apps. You will have to buy aftermarket items like a Wahoo Cadence to get that kind of integration. However, for me, it doesn't much matter. I'm simply using this bike as a backup for my daily cardio workout that goes between 35 and 90 minutes, so I only use the computer for a distance measurement. There are so many fitness routines and POV cycling tours available on Youtube and other places for your iPad that it's mostly unnecessary to stare at the small LCD screen anyway. It's nice that they included the computer, but I like that they kept it cheap to keep the overall cost of the bike down.

Good value, attractive finish and styling, mostly easy assemble and smooth, quiet ride make this a winner in my book.
