Changing sprockets on Shineray X1

[VroomVroom]

So I've decided to do the most important change to my Shineray x1 (150gy-11a) bike that I need.
The bike gets to 5th gear within no time at all and revs very very high whilst cruising. The 2nd/3rd gear are useless so I skip
through them in seconds.

I'm trying to find suitable sprockets for my bike but not sure where to find. I believe the current setup is 14/45.

What should I change the sprocket size to?

What size chain will I need for the new sprockets. Anyone know a good source for a genuine DID O-ring chain on taobao?


Any help is appreciated. Thanks.

You can get everything you need at the moto market north side of Chengdu just outside the 3rd ring road on highway105.
Don't try and gear that thing up too high , it's easier and faster to change the front, up one tooth is probably all it will take.

14 I think is biggest you can easily get but look in taobao I think I saw some!
I have 14/43 that's about the max it will pull without loosing a lot of hp
Revs lower same basic speed and slightly less pick up but not much
Mine what same as yours and 5th at 50km
Revved okish at 80km but anymore was high rpm
Now it's pretty good

I went the parts market and they didn't have suitable sized sprockets so I gave up.
I'm not sure what sprockets would be suitable for my bike on taobao. The ones advertised for my bike don't seem to offer any options.
