DJC Suspension Seatpost Straight Pillar Headless Bike Seat Post Shock Absorber for City Bike MTB 25.4 27.2 28.6 30.4 30.9 31.6mm

They're replacing the wqater mains in our neighborhood and the streets are being torn up daily removing the old pipes and replacing them with new ones. Once they complete the process they will repave all of the streets. In the meantime you feel like you're riding on the moon! My e-bike has no suspension as it's primarily a street bike.The suspension seat post works so well that I decided not to move forward with trying to replace the fork with a suspension fork.This was a much easier and more economical way to greatly improve the ride quality od my e-bike!

Have these in all my bikes. Saves u o especially on long rides. This one is very sturdy and no wobbles. Installs easy.. adjustable too.

I'm happy with this seat post. Definitely adds some comfort to the ride. I took off one star for the weird instructions on how to adjust the suspension.

This seat post works great and makes my bike a lot more comfortable. I bought a cheap Walmart Huffy Rock Creek 26 bike that didn’t have any rear suspension. I put this seat post on it, and now I can ride over bumps and the shock soaks them up. I like how it has an adjustment on the bottom of the post, so you can easily adjust it to be stiffer or softer. Couldn’t be happier with it for the price.

exceeded my expectations

Yesterday this aluminum zoom seat post failed. Almost killed me. I was crossing the street on my Urban Firmstrong beach cruiser and suddenly BAM!!! —- I fell to the ground. If a car had been nearby and rolled over me, I would’ve been dead.Also, look at the picture. That sharp, jagged edge of the aluminum seat post was sticking out past the frame after it broke. As I was going down, if that jagged edge had caught my leg, and an artery, I wouldn’t be here writing this revised review. I would’ve bled out in 30 seconds.First, I had the seat post inserted safely past the insertion point. In other words, I did not have it sticking out too far. I am 210 pounds, 6’2”, and maxed out the length of this Seatpost. Therefore, I was putting more strain on this post then someone would have at a lower weight with it pushed in more.Second, the beach cruiser frame is made of steel. This Zoom seat post is aluminum. Eventually, steel wins.Third, these 1 inch seat posts (25.4 mm) were never intended for adults. They were intended for children. Back in the 1960s and 70s, kids rode bikes with 1 inch seat posts. The bike designers probably did not imagine that adults would also be riding these bikes. The standard stuck. The seat post diameter is simply not large enough. Ideally, it should be larger.Fourth, the thickness of the walls of your seat post is very important. In addition to the material. My recommendation is to get a steel seat post with thick walls from a name brand like Wald. Maybe even change the seat post every year or two if you ride a lot and are heavy.Finally, I originally posted a five star positive review for this Seatpost. However, I feel compelled to warn others of this danger. Not only for this seat post but all 1 inch seat post, especially aluminum inserted into steel. I rode this Seatpost for a couple years without any problems, then suddenly it failed. Catastrophically.I hope this helps people to consider the importance of their seat post, the dangers presented, how suddenly they can fail, and the importance of using a strong, steel, thick seat post especially for 1 inch seat skinny seat posts. Good luck, travel safe, and have fun.

Hasta ahora bien. Ha funcionado y no se siente fuga o pandeo. Llevo unos 300 km y no parece haber desgaste

This adjustable bike post is well made, but there is very little range of movement, and it is way overdamped.
