I was really looking forward to getting this exercise bike, as I have trouble walking due to a disability and riding a bike is easier for me. The description said the bike was made for riders between 5'1" and 6'5". I am 5'2" tall and can BARELY reach the pedals, so that it makes sitting on the extra large seat really uncomfortable. I actually tried putting my walking shoes on AND strapping on another pair of walking shoes to try and make me sit better on the frame. It did boost me up an inch or two, but then my feet quickly became tired trying to stay in the two pairs of shoes and the pedals. Sadly, I couldn't adjust the seat down, only up. I do like the smooth pedaling and how easy it is to adjust the tension, making it either easier or harder to pedal. The Mode button lets you select and lock on to the particular function you want; such as, TIME: your total workout time will be shown; SPEED: this shows your current speed during your workout; DISTANCE: this shows the distance you 'travel' during your workout; CALORIE: this shows the calories burned; PULSE: placing both hands on the metal part on the handle alows the heart rate sensor to measure the number of beats per minute; ODOMETER: shows the accumulated workout distance and then SCAN: this display scrolls through Time, Speed, Distance, Calorie, Odometer, and pulse every 4 seconds. If there isn't a signal (you aren't doing anything on the bike) for 4-5 minutes, the LCD display automatically shuts off. This display takes two AAA batteries that are included. NOTE: This wasn't in the booklet, but I figured out that I could clear the previous session numbers by pressing and holding the 'MODE' button until I could see all zeros. If space is a problem, then you will love how the bike folds for storage. When open, the bike is about 2 feet wide by 3 1/2 feet long, and when closed for storage, the bike is about 2 feet wide by 2 feet long. The instruction booklet listed dozens of parts, but a lot were already used for the "some assembly required". Out of 89 listed parts, I only had to deal with 26 parts. It was fairly easy to put together, even when the booklet didn't list all the steps. For instance, after putting the pedals on the bike, it doesn't tell you how to install the straps. You have to go to the end of the of the booklet under 'adjustments' to find out how to install the pedal straps. Also, on page 12, step 4, it talks about connecting the hand pulse sensor (9a) with hand pulse sensor wire (79), then connect the computer wire (9b) with sensor wire (37) and then it says to see Pic E. But there is NO Picture E! It only goes to Pic C. Also, on picture C, it shows 2 connecting wires for (9a) going to 2 connecting wires for Hand Pulse Sensor Wire (79). BUT, there is only ONE wire of both (9a) AND (79)!!! Some of the wires were already connected, so that could be part of the issue. One last thing I would wish for while using this bike, is more detailed instructions on actually using the bike. Yes, I know. It's just an exercise bike! But when it comes with all the bells and whistles, I want to know how to use those bells and whistles so that I can enjoy the bike to the fullest. Also, the description of this exercise bike claims it has a 400-Pound Weight Capacity, but on the bike itself is a sticker that says the maximum weight capacity is only 325-Pounds!
