JFOYH Coil+Oil Shock Absorber Adjustable Damping Hydraulic Rear Shocks For MTB/E-Bike/Scoters, 125MM/150MM/165MM/190MM 550LBS/1000LBS/1500LBS

Mounted this on a 5 year old Iron Horse 29er that still had the original coil shock with hundreds of miles on it. I’d put an air fork on the bike a couple years ago and that’s been a great upgrade. But I didn’t want to deal with an air shock in back…for the terrain I ride, it’s just not worth all the pedal bob and servicing that come with air. This hits the happy medium. Practically no pedal bob due to a heavier spring, but with the rebound cranked way down, it sucks up a lot of the bumps comfortably and without the pogo stick effect of a basic coil spring. Especially on areas where any kind of tracked vehicle has left washboard terrain in its wake. And it should be pretty much maintenance free beyond cleaning it now and then. I’d make sure to grease the bushings and bolts before install. Came with two standard short 8mm bolts and one longer bolt for mounting to the rear rockers.

Better than a spring, adds some dampening to the ride. I installed on a SunSeeker Fat Tad CSX and fit was perfect, it's 5/8" longer than stock but this wasn't a problem. I do wish it was offered with different springs as the 650 pound one is a bit stiff for my weight (195). 450 would be nice. But it does improve the ride, not as jaring as stock so a good update.

I bought these to modify and install on my Ecomobl M24PRO electric skateboard. The board has 4 wheel double wishbone suspension and 165MM was the exact length of the factory shocks and springs. I ordered these with the lowest spring rate I could get and sourced 150LB springs that would work with them because the 650lb were way too stiff. I like them so much I bought a set of EXA 290's as a drop in replacement for my Propel X4S. Both boards had hollow shocks from the factory and the ride is incredibly improved with these! The board feels more stable, and being a skateboard, the deck stays flatter over undulating terrain so the rider isn't having to compensate for steering upsets with their feet. Thanks to these characteristics it's not nearly as fatiguing to ride fast over rough terrain and I don't get off with sore feet! I'm not sure what people mean that their rebound adjuster doesn't work, mine makes a huge difference and I leave it as fast as I can in those application. I liked them so much I basically bought them twice, the 290's were a drop in for the Propel which came stock with 260's, from what I can see EXA 290 and 291R like these only differ by the rebound adjustment knob.

Works better than expected

Shock feels great on my Razor mx650, and I was satisfied initially. Rebound adjustment knob fell off during normal use within a month and is missing. Impossible to adjust now, very disappointing.

Rear shock was in the process of destroying itself that came with my Cyrusher Kommoda ebike. It was leaking a tad of oil while being a squeak machine with 400 miles on it. It was also WAY too heavy being a 750 pound unit. The only time the rear suspension compressed was going over curbs. Probably how I damaged the default mystery gosuxe brand that goes and sucks. Proper name for it. Much MUCH better now that I swapped the rear shock. Still a tad much with the 650 pound spring but its night and day better. Only issue was the weirdo sized bushings that this bike uses. Had to press out the bushing in the JFOYH and then, with MUCH effort swap those bizzare bushings in the Kommoda over to the new shock. But it seems to work. No more squeak and the rear suspension does flex a bit over bumps.

I bought the 1500LB suited for a 230Lb person(s) but it’s way too stiff and I weigh 225lb.

The media could not be loaded. Installed it on a electric unicycle. I thought it would at least handle my body weight, 230 pounds. Installed it, test out how much resistant it has, it couldn't even handle me doing my standing pushup pressure on it . . . 650p, I am very disappointed, wish there was a 1500p or at the least 1200p.Edit: the supplier saw my review and they designed a 1500lb version just for me. Great customer service, beyond and above. I would give them a 5 star but I still have to test out the suspension to see if it does the job. The design of my electric unicycle suspension is also flawed, so I'm going to have to redesign my own suspension arm and test this suspension and see how it will work.

Great replacement for the original shock that decided to pack up.Delivery was quick and packaged well

Semble bonne qualité, bien emballé, sera utilisé comme remplacement de suspension a l’air pour un unicycle electrique Begode Master. Note dans les instruction d’usage il est spécifié qu’il ne devrait pas être utilisé pour un usage agressif comme freeride, downhill, ou jumping ce qui pourrait endommager le coil et annuler la garantie…

Bon

Very happy. I an heavier and would bottom out with stock shock now no problem straight out of the box spring placement as well just perfect for me and my application

After riding with this coil shock and it's extremely bouncy. It does not dampen the compression, only the rebound. Even the rebound adjustment does barely anything.
