Marcy Recumbent Exercise Bike

Props to Amazon Prime shipping. I ordered this and received it within 2 days. The box had 6 hard plastic straps, so I was able to drag the box inside & up a flight of stairs without help. I unpacked all the pieces. This bike was packed very well. As a detail-oriented individual, I noted only 1 piece had broken through its packaging & that piece caused no visual damage. Another packaging compliment: the hardware required for assembly was very well packaged and clearly identified IAW assembly instructions. I read reviews that said it took a couple guys 20 mins to assemble. I was very deliberate & assembled on my own as a single female. It took me about 2 hours, notably trying not to damage my hardwood floor. I also read a review that indicated the manufacturer included extra washers. Not the case. Rather, the instructions have a few typos. 1. Pg 6 says "(in bold) Do not tighten nuts and bolts until instructed to do so". Only assembly instruction 1 tells you exactly when to tighten them, so for the rest of the instructions, tighten as you go. You won't be instructed. Step #2, pg 7 says "secure the front post to the main frame with 4...bolts and 3...curved washers". You obviously need a washer with every bolt. You won't have extras, just follow common sense here vice instructions. When you attach the seat base, you may run into 1 Allen bolt that refuses to engage. Not sure what the deal was with this. No issues with the other 3. Other than one other minor fame vs frame misspelling, step 1G will have you"attach the M8 leverage knob on the floor completely to stabilize the bike before exercising ". There is no rational or practical way to attach the knob ON the floor, as far as I can tell, you screw it into the base frame of the bike. I have triple-tightened every piece of connecting hardware on the bike, yet it's somewhat unstable. When I pedal, the seat rocks slightly forward & backward with the motions of my pedals.Otherwise, this bike seems a good value for the cost. Money was not as big a factor for me as simplicity & ability to assemble & move the thing alone. Assembly was not terrible nor cumbersome, just think perhaps the instructions could use some quality control. The computer seems also to occasionally skip the calories option, so all you have to do is scroll back through to get to it. In summary, this bike will help in getting more fit & burn calories, however the rocking instability seems to stem from the frame connection at the length adjustment knob and I haven't identified a solution to this as yet.UPDATE 3/8/17: have had this bike for a couple weeks... cycled less than "400 calories" on the meter. There is a ticking noise that has developed in the wheel well (for lack of a better term). Since the whole thing is closed off, I have no idea what is causing the noise. If I pedal faster, the noise goes away until I slow down. Overall, I think this bike was overrated. Reduced to 3 stars from 4 because it still works.
