I'm a 5'4", 70 year old women. It can be hard to get my leg over the middle to get on the bike. Little high. It also needs two wrenches to tighten the peddle. One for the bolt and one to keep the peddle from turning on the other side.
Saying that, I think the bike is great. Love the comfortable seat and the quite ride. The arm exerciser is also nice. Keeping your arms toned at my age is not easy but this exerciser is great for that.

Found this bike by chance after being put on a diet by my doctor. For the price, it's a great buy. The rundown for me goes as follows.

Pros:
-Great for shorties like me. I'm 5'2" and finding a bike that fits my stature is hard. This one nails it.
-Foldable, which is super convenient if you live in a small space like I do.
-Straightforward. It's fairly easy to use. You don't really need to read the menu instructions but they are available.
-Isn't too difficult to assemble. It took me closer to an hour to do on my own, but a lot of the screws were already in where they should go, which is helpful. If you have soft hands, do as the booklet says and wear gloves! The instruction booklet lays it all out for you to easily understand.
-Good tension options for a challenging workout. I don't need much, but for me, putting it past level 3 will get me sweating, which is good.
-Relatively quiet. There is a soft clunking sound that will go off every 4 to 5 rotations but it isn't anything loud. Other than that, it's pretty quiet. You can barely hear it over the tv.

Cons:
-The seat could be way better. I don't know in what universe this seat is soft, but it isn't this one. Doing 37 mins of exercise the first time left me with a numb and bruised bottom. I had to order a seat cushion, so hopefully, that will help. I assume this will vary from person to person depending on one's weight, but I would never call this seat comfortable. At least the seat is wide.
-If you are short like me and use the last seat adjustment hole, you have to adjust the seat up, putting it higher by a notch or two in order to fold the bike properly. When you don't, the pointed edge of the seat knocks into the cellphone/mp3 holder, preventing it from closing fully. I just went ahead and removed the holder.
-It's tricky to get on and off the bike. If you have some joint issue or a disability, this could be a major drawback. I have to swing onto the bike like it's a horse because the handle bars connected to the seat get in the way. But they can be removed. It'd just be better if they could be folded back.

Other than that, it's an overall great bike for the price. But of all the cons, I really wish the seat was more comfortable. I could've saved myself money from having to buy a bike cushion, which aren't cheap at all.

EDIT: buying a bike seat cushion and bike-riding shorts helps a lot with the saddle soreness!

EDIT TWO 3/22/21: I have been successfully losing weight and building muscles in my thighs and calves using this baby 4 to 5 times a week!

I purchased this bike for a 2nd bike to have because my first one I put in our camper. 1st bike much cheaper and been using about year and half. a true recumbent bike that has several positions from played back to upright. The description of this bike says 2 positions, wrong. There is only 1. But you can sit straight up or simply lean back on the backrest. However, the backrest is super short and cannot be moved up. It hits on my very lower back so doesn't give much support. The seat is AWFUL. Super hard... but it is wide. Also, the counter is not accurate at all. I time my 1 hour work out on my watch and it is never correct. I do not believe the distance is either. I know how far I can go in an hour and it is not accurate. I contacted customer service to return the bike. They offered me a small refund to keep it. I thought about it and the bike does provide a good workout, just not comfortable. I decided to keep the bike, take the small refund and use it to buy a new gel seat cover. I am hoping this helps. If you want a straight up ride, with no option to recline the bike, it works. But if you are looking for a recumbent bike, this is not it.

I felt like this was pretty easy to assemble. It folds up very easy and I love that to help with storage. I'm 250 and it holds me up great it doesn't feel unsteady and I'm about 5'8 or so and it's perfect fit for me. The seat is adjustable so it could go higher or lower so I feel it would fit someone shorter or taller than me with no problem. The seat is a little hard but reviews on almost ever bike I saw said that so I'll just buy a pad for it. I was worried about this purchase and I just want to say I love it so if your skeptical about this like I was hopefully this review helps!!

I was looking for a foldable/moveable bike for moderate exercise. I also didn't want a computer screen -- just one more thing to break/repair! Just a simple interface works for me -- I remember how many bikes/treadmills at the gym were out of commission b/c of the computer screen!

So far, the bike has been excellent -- it is very quiet, the resistance settings are fine for a moderate rider.
The bike was pretty easy to set up. I did have 1 issue that wasn't clear in the instructions. I called the number and got it resolved quickly.
****Definitely order a gel or foam seat pad for this bike -- the seat is about 11" wide, 10" long. If you order the bike, order a seat pad at the same time.*****

NOTE-- the distance and speed measurements are in Metric units -- kilometers (km) and kilometers/hour (km/hr). A km is about 2/3 of a mile (actual is 0.625 mi). So, just take about 2/3 of the reading, and it's close enough! So if you're riding at 24 km/hr, that's about 16 mi/hr (roughly -- it's actually about 15 mi/hr). If you rode 9 km, it's about 6 miles (5.59 actual). This is not a deal breaker for me. If it's important to you, have a post-it note of target km or km/hr values that you need.

Some reviews complained about the noise of their bike - maybe they need to tighten the fittings.
Also, some reviews complained about not enough resistance -- I think if you are a serious/heavy bike rider, you probably need to look in a different price range than this bike!

This bike has been perfect for me so far. Highly recommend it.
