I just bought an electric tricycle. The seat was hard on it, so I upgraded to this seat with the back rest huge improvement. Do yourself a favor if you buy any bike and the seat is uncomfortable, replace the seat with this one. You will not be sorry.

Needed a different seat for my MoonCool Trike bike since the one that came with the trike is too small. This MoonCool bike seat has a large cushioned seat area and the back is adjustable. The seat will slide back or forward only by .5-1”, but the back rest will adjust up and down . It definitely looks and feel like much better quality than the seat that came with my trike.

Comfortable saddle. Nice color and works well. The back does give additional support but also limits the ability to get on or off the bike from the back of seat.

someone said it didn't fit there tk1, well it does. the 7/8 round post holder is easy to remove. then flip over your old seat over loosen the hex head bolt till the rail mount opens up and mount the new seat on the rails. tighten hex head works great, seems comfortable but like the back plate for the sturdiness so I don't slide backward 8 /18/25 I have an update while switching the bike stem on to the seat I discovered that in China it's ok to match an iron bolt with an aluminum locking nut. needless to say I stripped it. I replaced the bolt with a 10mm hex head bolt 1.50 thread about 1/2 longer and a 10 mm nylon nut drill out aluminum locking nut you need it put the nut on top of that works great really tight. The old bolt thread size is 1.25 couldn't find, don't forget small thin washer for the base of the bolt hope this helps

I bought this as a replacement seat for my electric scooter. It arrived on time & well packaged. It seems very sturdy and good materials, sadly it was not big enough for my needs. I'm a big person and it was a bit uncomfortable for me. If it were just a few inches bigger & the front tip shorter I would have definitely kept it.

Feels great.

The bars were welded to close together to get the bolts in so i had to drill out the holes slightly. The mounts were welded on crooked so the seat leans to the side. The seat itself is made of thin plastic. I weigh 200lbs and if I lean either way slightly the seat wants to bend and dump you off. Complete junk.
