Bounces on platforms

So i have an infinite runner type 2d game. The 2d platforms are generated next to each other. No gaps. When i run the game i can see the platforms are side by side as should be… My player is on a bicycle with a circle collider, ive tried box. Every time my player rolls over the connected platforms he bounces. When the speed picks up, he bounces way in the air. I dont get why. There isn’t anything for him to bounce off of. I have a rigidbody 2d attached. Any help would be appreciated.

image to show the issue

it seems that my collider is going through the land colliders. I have collision detection on continuous. and extrapolate. Ive tried box colliders and circle. Ive messed with physics tab and no luck. Ive messed with gravity, mass, no luck…

Now when i use circle colliders he bounces. Box colliders he gets stuck… Im lost lol

i’m not talking from exprience as i’m a 3D developer, only did 2D on Flash.

this issue is a 3D problem too, but i think only 2D has a solution, use edge collider for the terrain, i guess you use box right now?

I also tried edge but same result

It just seems that the edge collider isnt continuously finding the land collider. It drops below it ever so slightly and then gets stuck.
