Input:
Question: There is a long silver bolt on the bottom.  What is it supposed to do?  Perhaps this is relevant to my previous question about buckling?
Document: My Overall assessment of design and build quality is poor. While using the bike the frame and seat post wiggles, lurches and creaks loudly.The bolt points at the frame and seat are not well placed and it causes the bike to lack sturdiness. The monitors calorie count function was also dead on arrival.At this price range i have to believe that there are better options! My recommendation is to look at an alternative bike.
jumping from 78 to 128 back to 95, etc.) It is overall an uncomfortable ride, though I did like the adjustable seat. It also is touted as being movable, with rollers, well, that's rubbish as the rollers are so tiny you're better off picking it up and moving it, but don't, because it's heavy.For the shipping. Oh my, what hell have I descended into? First bike arrived with the packaging so damaged that I chased the UPS guy to take it back!
With arthritis in back, legs, hips and knees, I found myself moving less and less so I started looking for some way of exercising that would work for quirky, forgetful and uninspired me who lives in the rainy Northwest. I used a recumbent bike in physical therapy a couple of years ago and liked it so that is what I chose. I have been using it daily in the almost two months I have had it and find it works well for me.
We really like this bike - it isn't too big, it has a few fancy settings, it was pretty easy to put together and it is pretty comfortable to ride. I think there were complaints on how the seat kind of needs to be moved manually - but honestly - it is less likely to break the way they have it set up - sometimes too fancy can cause more problems.We like it!
Was a terrible experience. Not Amazon's fault but the manufacturer. The electrical part did not work. This was after my daughter spent hours assembling the bike. All you had to do is plug in the wires to another wire so I know the product was faulty. I wish I would have listened to other reviews. Once we started to assemble we threw the box away. That was my fault but never thought something like this would be faulty. We had to disassemble the bike to ship back.
They've been very good about these returns, and I asked for a discount on a bike if I decide to completely neglect my sanity and buy another bike from them, and they capitulated.Moral to this convoluted story, Do.Not.Buy.This.Bike... unless you're a masochist.
The only part of the instructions where the diagram was hard to understand was for the plug-in on the pulse reader hand grips. Looking at it, we thought it was in the end piece. We finally found it on the left side in the housing under the seat. I like the fact that you can walk though the middle and the seat is pretty much chair height so getting up and sitting down is easy.
The bike itself is great, actually it's pretty fun to use. It's comfortable, rides smoothly, and it's quiet. I'm overall happy with the purchase. The workout programs are good, but there's a couple that I generally use and then ignore the rest.I've seen reviews that say it's flimsy because of the way the walk-through design is bolted together. This can be true if you don't really tighten down the bolts.
The bike is made to last and easy to put together. I especially like the heavier than normal flywheel weight. Most other bikes on the market have flywheels that are only 13 lbs or less. This bike has a hefty one that maintains intertia much better, and makes for a smooth rotation.
Purchase a different brand.
