Rocker plate

Are rockerplates available somewhere or do we need to build our own,would be fun to get a even more realistic ride!

I am extremely happy with my Coplate from BikeAcces in the Netherlands.

If you’re handy, build it yourself. Way cheaper.
Any Company that sell those are way too expensive.

I’ll build myself a very primitive one with things that lay around in my cellar.
I’ve read about those only yesterday.

Yes,they seem to be around $400,will probably build my own,thanks.
