If you're open to something simpler my son custom makes normal wooden ramps. You're welcome to take a look. He started the business at 15 to fund his riding. He's in Andorra for DH World Champs right now, so there would be a bit of a delay on any orders 😊 https://www.thehunters.co.za/ramps

Someone used to import them, but Im not sure if you can get them anymore. I see there is a local company making something similar https://mtbbuddy.co.za/store
