Nothing to dislike. Eats road bumps like they don't exist. May be not for the outdoor slammers, but for the City with occasional dirt road - flying colors. My butt is happy!Work Great. Makes my ride much more enjoyable. ThanksGreat adjustability from soft to firm according to rider weight or terrain. Very quick and easy install. Riding is like night and day now and no need to rise up off seat going over bumps. Eliminates pressure on lower back and butt. Best upgrade I've done to my e-bike!I am having problems with my seat post and after contacting the service dept they do not honor warranties for any shock bought on AmazonThree month review. This is my first suspension seatpost so I can't compare it to anything else but for my ebike conversion commuter, I am loving this (and so is my butt, back and neck)!60yo male I weigh 190lbs (86kg) and right out of the box the preload is just perfect for me with no adjustments needed. It's not too bouncy yet 'gives' at the right moment for dips and bumps. The difference between this ride and stock is like night and day. In fact the ride is so smooth you could carry a cup of coffee in your hand without spilling it. And I have... not once but several times.Just make sure you measure your seatpost to get the right fit or it won't be a pleasant experience. Five stars!There is no cover to seal the working portion of this seat post and it came with a seat post sleeve to make it fit my seat tube. Unfortunately I ordered a size too small and seller is forwarding me a new sleeve to make it fit properly. This does work and it is comfortable to ride. I would give it 5 stars if it actually fit with out the sleeve but I do recommend it for added comfort riding.Very good product. You absolutely need this if you bike a lot. This will help your back and spine A LOT!
