Question: Can it be used without electricity?
Document: Will try Nautilus next. Will change review if I can get product fixed without taking it anywhere.
Do not let anyone tell you that they put this bike together without help. Just getting on the monitor take four hands. On issue we found was the instruction booklet. When mounting the back of the seat the instruction booklet shows four holes in the metal unit................wrong. You just attached the back plastic piece to the front and that is it.
If you don't take your hands off for very long it will go back to the correct number pretty quickly. I bring this up because the equipment I've used in the gyms gets to the correct pulse very quickly.
The display is clear and bright and you do not have to have bright lights on to see it. So far I use the Quick Start but intend to pursue the routines once I am used to it. I started at 10 minutes a day, went to 15 and am now at 20 minutes a day.
I have used the bike nearly every day for months now, and it is precisely what I have needed. It's sturdy enough to move around and take my over-exhuberant sprints. It keeps good stats, exactly what I was looking for, and the exercise programs, while simple, are enough to keep me going.
Yes there are no instructions but it reads on the bottom of the console just as the Nautilus bike in the gym reads, it offers the instructions for manuel or a course. I used the manuel last night. Today I gave the "my nautilus" button a go. I set up my profile, and then with a little back and forth created my own "custom course". I like that feature as it then stores all the stats in your profile.
Don't buy this unless you are sure your delivery guy is able to deliver this 115 pond box without smashing it. After I got my bike I assembled it and found that, due to the frame being bent, the belt connected to the pedal was misaligned and kept coming off. This is a heavy metal frame so it must of took quite a blow to bend it. It came in a very heavy and big box so I guess it was too much for amazon shipping companies (UPS) to handle correctly.
It includes a cup holder in the console and water bottle holder on the console shaft. There is a book holder at the top of the console which you might use to hold you Kindle or iPad for either reading or streaming media.The console is pretty big and is easy for my old eyes to see while using the bike. It is not very intuitive to operate however so I recommend downloading the PDF and keeping it handy until you get used to the interface.
Instructions for assembling the bike were easy to follow and the bike itself is comfortable to ride. I have used institutional recumbent bikes in the past and find the nautilus to come close in performance. The only real difference is in the weight of the bikes themselves. The Nautilus is a little less steady than the institutional bikes especially when it is being worked hard.I believe that I made an excellent choice when I purchased a Nautilus over the other brands that I considered.
The bike arrived quickly with no damage to the outer box. It put it together myself in a few hours. The bike worked fine for a few months. The position of the handle bars was mildly annoying, but I got used to it. I love that my iPad stays firmly on the book rest and the bike doesn't move too much when pedaling. The fan blows way over my head, so there is no way the air stream could reach me, even if I tilted the console.
Answer: no
