Does it have a smooth - no jerking motion?

No it doesn't have a smooth no jerking motion. I found out too that the more you crank on the tension the worse it gets.

It can have some jerking on the higher settings, but it gradually becomes smoother over time. Mine doesn't jerk at all any more.

Yes. The motion is smooth. This unit must be securely mounted. What I did was use water hose clamps (Advance Auto) to mount this unit to the bottom of a plastic milk crate.Then I secured the milk crate with two wood screws (Home Depot) to a piece of approximately 3/4" thick x 1 1/4" wide x 4ft long wood (Home Depot). I then secured the 4ft long piece of wood to a table with 6" screw clamps, and 2"x4" studs on the bottom so that I would not damage the table. Much of what I needed for secure mounting, I already had. Use your imagination for secure mounting. I just finished using my unit. The important thing to remember is, THIS UNIT MUST BE SECURELY MOUNTED. Yes. The motion is smooth. This unit must be securely mounted.

It is rather a smooth motion but you must remember to pre moisten the plunger and it will move more smoothly. I use it to feed my old finicky cats or give them supplements and it has held up rather well through multiple cleanings.

No, not a smooth ride at all. The adjustment doesn't help with smoothness either.

I would consider it smooth. There is a very minimal amount of texture; just enough to keep it from being slick smooth.

It does have a bit of a texture on the board but nothing distinct enough to keep it from moving. Just keep your fingers light and your wrist up so there is not so much weight pressing down and it should glide as smoothly as needed.

Yes the ride is smooth. I did have to secure the rubber tips with gorilla glue to keep them in place when pedaling on carpet, but overall there were no problems with the equipment.

It glides smoothly but does make a slight noise. Not sure of WD-40 would help but it is worth the price.

Yes, very smooth operation. I find it simple to use and easy the changer the belt. Recommended item.

Nope. The mouse wheel is quite stiff, in a solid feeling way. it does not spin freely.

No "clicking" but a smooth intuitive turn of the control knob. No problem unless you crave the feed back.

No it's smooth and silent. I hate squeaky anything anywhere and my bike is no exception. Amazing pedals but watch your shins!

I would say there is very little vibration...very smooth and light, as well. I use mine for trimming what my rider mower can't get.

It's toggle-able between smooth and click scroll. Click scroll may be loose depending on your preference. Seems fine for me.

nah its smooth. takes a around a second to close the valve so that prevents the hammer effect. I dont think it's powerful enough to instantly close the valve. I have it run for 15 minutes daily to top off my pool in the morning. If it caused noise, I would have set it on fire by now.

No it's not vibrates, and this is the best machine ever have, I am truly happy with it

No, poor feature as the power driven wheels click and don't rotate smoothly without resistance. It moves but not easily and likely impacts the life of the drive feature.

Seems smooth and not jerky to me but I think it depends on leg strength to begin with. As your leg muscles stretch and get stronger, the pedaling should become less jerky, if jerky is what is happening now.
