Question: 230i How do you move the seat back for leg length?
Document: After having major back surgery I needed something for both cardio and leg strengthening . I decided on the bike over a treadmill. Amazingly quiet, extremely comfortable for having had back surgery and a good variety of programs that are easy to set up. The display is very easy to read and understand. Liked the large pedals, with the ability to remove the straps, which I prefer to do. Delivery was excellent with free shipping . Set up was easy with tools supplied.
My whole family uses and loves this exercise bike. It's super comfortable and easy to use. It was a little bit complicated to set up, but the directions were easy to follow and tools were included. This bike is pretty heavy, but the handle on the back and wheels make it easy to move it around. I will be getting an exercise mat to put it on so the carpet doesn't get messed up; you may want to order one along with the bike if you get one.
We haven't had to change the seat adjustment as my husband and I have the same length legs. We are also the same age but we do have to change the weight setting. Entering the info at the beginning takes just seconds. I like how the program remembers the previous settings so you don't always have to start from scratch. It even remembers the intensity level for a particular program.
There are preprogrammed routines or you can program it manually if desired.It is very stable (I weigh about 200 lbs)It doesn't take a lot of room and doesn't weigh a lot... about 106 lbs, and is easy to move around.It is easy to adjust the pedaling distance to get a tighter angle on my knees if desired.The seat could use a little more padding, though.
Had no problems with packaging and arrived within two weeks after ordering. It took around 2 hours to assemble, wasn't hard, just took time and I found no steps missing. I'm a 5'3" woman and find that the seat adjustment works fine for my leg size, I am still not at the closest setting. Very impressed with the quality and workmanship. As other's have stated, when operating it is practically soundless.
Good pre-programmed options. Like the fact that memory saves the last setting so essentially I can zip through settings and start working out quickly. Haven't had to use the fan yet. The workout is noticeablly strengthening my legs and the recumbent seat causes no strain on my back. Highly recommend.
Just a couple minutes of extra work there.The only thing that could be difficult for one person to do by themselves is when you are attaching the seat frame and rail back onto the bike frame, you have to reconnect a wire and stuff it into the frame, before you can set the whole assembly down. You could just as easily build the bike on its side to this point and then tilt it upright when done.The only defect in my bike is the fan didn't work, which is very common.
They just got a delivery of back ordered fans and I was told they are going into Q&A; right now before they will be shipped. My bike didn't suffer from the smelly seat issue that many had, nor do my pedals or the fly wheel make any clunking sounds. The foot straps are easy to install, I don't understand why others had issues with this.I think the bike rides really nicely. The resistance at level 16 is fantastic.
I went back to Sears to get a picture of the bike but the bike was gone. I assume they should fix their home page soon.I really love this bike and would give it five starts if I can again. The flywheel incident did upset me a bit but now I got used to it. I don't think it is a big deal anyway. The Heart beat controlled programs, adjustable ergo seat with shelf, bigger paddles and blue backlit console still makes it much better than the 230.
Don't be alarmed by the pulse counter. If your hands happen to move around during exercise, each time they lose contact with the "pads", that disconnection will be counted as a heartbeat, so the rate may show higher than it really is.
Answer: yes
