Great indoor bike

New to indoor exercise machine, after a lot of research opted for X4s, and after 6 weeks use I happy to say this was a positive purchase. Easy to build together and to link up to Bluetooth to use kinomap. The 4XS offers a range cycling styles mirroring hills and slopes very well. I would highly recommend this bike. Hope you enjoy your cycling.

Fantastic bike with a great price.

Pros: 1) very easy to set up. It took me about 40 mins. But I am slow with assembling things. This is the first product I've bought where they've labelled the tools and given u all the tools ( including an alan key with a phillips screw head. ) 2) pre emotive support. For me this is a large purchase. I received an email from joroto telling me how I can get support. 3) the bike is very sturdy and receptive. It feels premium. 4) the machine has improved significantly. Whilst I'll be using an app it's good to have everything on the screen. 5) apart from you panting, fighting for breath ( pressuring you're unhealthy like me) the machine is very quiet. Cons: 1) the pedals are uncomfortable. If you want to ride barefoot then you'll struggle. But it takes a normal bikes pedal so you can easily replace them. 2) the fitting of the handle bar is a little loose. Not a fault and doesn't make it unsturdy. But it's noticeable. 3) no heart rate monitor; I know I'm being a bit greedy wanting a heart rate monitor but it's the only thing it's missing. 4) slight one but the screen times out quickly it would be good to have the ability to change it in the settings. Things to consider: 1) it's very heavy. I assembled it on my own but if you can get a second pair of hands. 2) the instructions are easy to read. But one change I'd make is put the weights holder on first then the seat as the other way round means you have to re adjust 3) if you have carpet or expensive lino get something to protect the floor. 4) don't forget to remove the stoppers on the wheel before exercising. It's not included in the instructions. If you have common sense you'll be fine but if you're like me it'll trip you up Great bike at an affordable price.

Great exercise bike

Had this for 5 days now and i must say its very good. The only problem I had was the display unit kept rebooting when I put the batteries in which made me wonder if I'd made a mistake getting it. However a quick email to support suggested I put new batteries in not the supplied ones and they gave me the link to update it and video how to do it as well. 5 mins later and it was working properly. It was easy to connect to my android phone and ipad and my polar heart monitor. I've linked to kinomap and find that a very good app to get you started and work your way up to extremely hard workouts. All in all, I think its money very well spent. New update.. the only thing I can find fault with this is that I find the bottle holder is difficult to get to if you have a tablet on the holder, I have to balance it awkwardly to get to it. I will have a look at putting a separate one on somewhere thats more convenient.. Don't let that put you off because this is a very good machine, just as good as a Pelton I think.

Pre-covid, I rode a Peloton bike at the gym every other day for a little over a year. I loved it and it made me love to workout, which I never really liked before. But, covid hit and my gym closed and I didn't want to pay that much money for a bike. After a very long period of no riding, I decided to buy the Cyclace bike. It was great in the very begginging and started making so many squealing sounds and I had to adjust things and grease things regularly and it would still be so loud. The sound was driving me and my family crazy. I eventually sent back that bike and bought this one. I haven't had it for long, but it is just a shockingly good bike. It is very close to the Peloton in smoothness of the belt, flywheel and resistance feel. I only have a couple of issues and they are small/or can't be helped in a bike at this price range. Here they are:Handlebars: I am 5'11" with long arms and normally wouldn't even notice if something was not maybe the best for a shorter person. But, I think it is noticeable on this bike. The handlebars are set in a way that if I have the seat in the place it us supposed to be for my leg height and seat placement where it should be for my thigh length, the handlebars are about a half an inch too far away (see pic...I have it set as close to the seat as posssible). It is not a huge deal to me, but someone with shorter arms may struggle a bit. The handlebars are also a bit wider set than they other two bikes I have used. But, it has these inner bars set at an angle that I really like to use when I am in the saddle. The other thing is that instead of an iPad holder on the handlebars, it has two drink holders. I use it for my iPad anyway, but had to use two small bungee cords to secure it in place so it wouldn't fall during the more intense rides.Resistance: the Cyclace bike had felt resistance pads and I really disliked that. It made a rubbing sound and I knew after I decided to send it back, I would get a bike with magnetic resistance. This bike has that and it is very smooth and can give you as heavy resistance as you could need (our of the saddle too). My only issue is that the resistance starts heavier than the other two bikes. Not too heavy, just I never would have that feeling of my legs just flailing. Which normally doesn't matter, but sometimes at the end of a cool down, I really like to open it up. But, it isn't a big deal. But, the bigger issue to me is how many cranks it takes to get from the lower resistance levels to the higher ones. It feels like the resistance doesn't change that much for several turns and then it heats up pretty quickly. This makes some intervals a little harder when you go out of the saddle with high resistance and then a quick seated recovery. But, I am getting used to it and I am wondering if the company may know of some little tweaks. I haven't reached out to them.All in all this is a really awesome bike. It is so quiet, so smooth and very sturdy. There is no sqeaking and squealing so far. I really hope it stays that way. Peloton is nearly perfect for me, but this bike is so close behind it. When you factor in the cost of both bikes, it is a no brainer to go this route, at least if you are a thrifty person like me.I am so happy with this purchase! The only thing that could make it better is a resistance output, but at this price range, you just wont find that. I use my heart rate to guide resistance.Some things that I use to make the spin experience of even better is:Peloton app (12.99 per month without the bike. Worth it!)Wahoo cadence tracker (it displays on the Peloton app and is so easy to attach to your pedal arm)Spd pedals and clip in shoes (to me it is a must after starting at first with regular shoes).Fitbit- I set it to spinning and use it to watch my heart rate. It really helps to guide how intense I set my resistance.I also use a TV tray next to the bike to hold my a small fan, my weights and my water. It works great and you can just tuck it away when your done (see pic).I also didn't purchase a mat and it works great on hard floors. I do keep a small rug next to it so when I get on a off, I don't scratch the floor with the clips. I leave my bike in the same place, so I don't know how easy it would be to move it around, but it has the wheels on the front.That is it. If you are on the fence, I would absolutely recommend it. If anything changes, I will update my review.

The quality is excellent and the installation is easy.

Model number X4S was ordered. Installation is easy according to the catalog instructions, and a YouTube video demonstrating the installation process for the same model is also available. The quality is excellent; only the seat is uncomfortable and needs improvement.

My choice was a good one.

I chose this product based on its description and ratings; I now understand why the rating is so high—it truly deserves it. When it arrived, I expected installation service to be included, but I was informed that the delivery personnel only handle delivery! I initially intended to return it immediately, but I asked my brother to help with the assembly; it turned out to be easy, though it does require a second person. The seat isn't particularly uncomfortable—I find the negative comments about the seat strange! The manual does not include Arabic. I recommend this product.

Z2 training

Great indoor spin bike. I use it 3 to 4 times a week. Currently, training for a marathon in August this year. Idea is to do a good chunk of my aerobic Z2 on the bike. However, one small issue is that the 2.4 in adjustment space forth and back on the seat doesn't allow the seat to come forward as much. Thus, it feels awkward and not able to use the whole seat. Most times I am right on the nose of the seat. Is there an accessory attachment that allows the seat to move forward a bit more? But highly recommendable product.

Just used it for the first time and it seems okay. Spent a while finding the most comfortable settings and then spent an hour on it. I'm switching from a recumbent bike so it's taking some getting used to. A few things that bother me: The seat is INCREDIBLY uncomfortable. Extremely stiff and too narrow for my comfort. The pedals are a touch too short and also uncomfortable for me, though I think I can get used to them. Unsure about the seat though.. I see you can buy gel seat covers so may end up doing that. The knob to adjust the levels spins freely and it takes a moment to update the level on the screen, so I'm always guessing at how much I'm changing it, and then having to change it again once the number finally settles on the screen and it's not where I wanted it. I wish they had clicks or some sort of feedback so you can tell how many levels you're changing while turning it. The seat stays firmly in place as far as how far up and forward I set it; however, it spins freely side to side. I haven't figured out if there's a way to stop the spinning yet. And the seat can't move as far forward as the slot allows, and the handle bar can't move as far in either, because the handles on the knobs that're used to tighten them hits on the support bars and prevents you from adjusting them to the furthest extent inwards. But the pros: good range of height adjustments, smooth gliding wheels, doesn't make any noise, and nice range of levels. I'm running it at level 55 pretty comfortably so it leaves a lot of room for me to push myself on it. Overall happy. I think it's going to grow on me.

I like this bike and it was worth the price.

I found it easy to assemble the bike. The bike is very quiet during the the ride and I am really enjoying it. The seat is a little too hard and I am getting a gel seat to place over the current seat

Almost perfect

I've had 3 home spin bikes now and this one has been the best - heavy weight, highly stable ride, 4-way adjustability on both seat and handlebars, a monitor that actually logs most metrics - including RPM (something strangely lacking in many home bikes). Easy assembly on top of it all.Magnetic resistance is solid - it does not take many spins of the resistance knob to feel significant change. I am really enjoying the bike. Only issue for me is that the flywheel is advertised at 40lbs but is really 35lbs. Still a solid weight for good calorie burn but misleading is never cool.Nevertheless, you cannot go wrong with this bike. Maybe complain about the flywheel and see if you can get a discount

Great bike and great customer service

Waited to review the bike. But I've had it for over half a yr. I have ridden it about 5 times a wk since getting it. The only issue is the screen that keep track of the workout went out. I emailed customer service about the issue. They emailed back within 24 hours and I had a replacement screen in a few days. Easy 5 stars for the bike and customer service.

Exceptional quality for the price point

We are really pleased with these bikes, spent along time looking into which one to get.Very good quality and easy enough to set up although the tape within the box was annoying.If you are a regular spin goer then the heaviest setting is not as heavy as it could be but we’ve done two different Les mills sessions on them and they do the trick.Highly recommend if you are thinking about it and not sure which one to go for given the amount on the market but for this price point they are excellent value.

A good bike; it's a shame it isn't compatible with JOROTO's own app. Stability is excellent, and assembly is incredibly simple.

JOROTO has an Excellent Customer Service, Highly Recommended!

I ordered the JOROTO X4S bike, but unfortunately, the wrong model was delivered due to a warehouse error.The response from JOROTO's customer service, particularly Tiffany, was exceptional. She was highly responsive and worked diligently to find a solution that was fair and convenient for me, given the logistical challenges involved. The company took full responsibility for the mistake and quickly provided a complete and satisfactory resolution, processing a full refund for my original order.This dedication to resolving issues efficiently is truly commendable, and I highly recommend purchasing from JOROTO based on their commitment to customer satisfaction.I am rating this 4 stars because while the service was 5-star, I am still unable to comment on the quality of the X4S product I originally wanted to purchase. Overall, a great experience in how a company should handle problems.

Price was extreme for the issues that came with the Joroto X4S (honest review, not paid promotional)

Purchased the pricey Joroto X4S & have had it for a few days (not a long-term review, nor a paid promoter)Good:1. Quiet & stable so far2. Easy to put togetherBad:1. Seat extremely uncomfortable & will HAVE to be replaced ASAP!2. Handlebars are a problem. Even though they move horizontally & vertically, they only go so far & make it ergonomically challenging for anyone over 5'10".3. Handlebars have zero padding for hands & are hard as a rock, so after a short 5 minute spin, without the ability to move the handlebars higher to a better position, the palms take a beating from the weight of the body leaning forward into the bars (& the seat is too uncomfortable to ride without hands)4. The electronic pad that comes with the bike connects to a cord that goes to the fly wheel. The problem is that the cord is spring-style & pulls down on the electronic wiring that's connected underneath the box that's connected to the handlebars. The wiring nearly broke off the electronic board after the initial connection on Day 1Overall, 3 stars is the max & I'd give the Joroto X4S. The price was extreme for the issues that came with it. The problems could easily be rectified with a bit of engineering & if Joroto were smart, they'd provide their gullible consumers *free of charge* re-designed replacements as soon as possible, starting with the seat & the handlebars!Would I recommend the bike? Not unless they fix these issues. It's too much to spend for disappointment.

Smooth comfortable ride but malfunctioning monitor and unresponsive gear knob lets it down

Assembly:The bike is reasonably easy to put together, but it's important to ensure all bolts and screws are fully tightened. If not properly secured, the bike can feel unstable—especially under higher resistance or when standing on the pedals.Performance:Once assembled, the bike operates very quietly and provides a smooth ride, which is a definite plus.Main Issues:Defective Monitor:The biggest issue I’ve encountered is the monitor. It appears to be defective—I can’t access the factory mode to accurately calibrate the resistance. As a result, the wattage, calorie count, and resistance readings are essentially meaningless, which defeats much of the purpose of having a monitor in the first place.Unresponsive Resistance Knob:The resistance dial is sluggish. It requires several turns before any noticeable change in resistance occurs. This may be related to the monitor calibration issue, making it difficult to fine-tune workouts.Tablet Holder Design Flaws:The tablet/iPad holder is fixed in one position and lacks a top securing mechanism. This makes it easy to accidentally knock your device off—particularly when reaching for a water bottle during your workout.Monitor Visibility:The display is clear and easy to read while seated, but becomes unreadable when standing on the pedals—limiting its usefulness during certain types of workouts.Overall:While the ride itself is quiet and smooth, the issues with the monitor and resistance control significantly impact the bike’s usability. If these issues were resolved, I’d be happy to give this a much higher rating.
