    • does fit tk1
Color: Black with Grey
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 ... show more

The only reason I didn’t give it five stars is because I don’t think the material that it’s made with is very good. However, the comfort factor is very high. I am a big guy. I weigh 250 pounds. It handled my big ass. And the backrest is great. You can push against it and pedal….. makes a huge difference. Mike ... show more

    • Sturdy well made seat but does not fit my needs.
Color: Black
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. ... show more

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. ... show more
