flips in one jump
2019. Nobody had ever performed seven.
2020. A year later, one more.
2022. On a trampoline we built with BERG to make it possible.
Seven. Eight. Nine.
Three world firsts in four years, all performed by Ernest Brenchley and filmed by Radial Flipz.
Seven and eight were done on trampolines that already existed. Nine was different: no trampoline on the planet could throw a jumper high enough to fit it in. So we built one with BERG.
In August 2022, outside BERG’s HQ in the Netherlands, Ernest performed the world’s first nonuple: nine flips in one jump, with the whole crew on the mat and the champagne out minutes later.
Each record clip has done hundreds of millions of views, and together they made Radial Flipz the biggest name in freestyle trampolining.

The trampoline that made nine possible.
No trampoline in the world could throw a jumper high enough for nine flips. So we designed one with BERG Toys.
The answer was size. The Pro 9 is a super trampoline big enough for six double bouncers to work comfortably on the same mat, loading the bed together to throw the jumper higher than any trampoline before it.
From CAD files and mat samples in BERG’s offices to the build outside their HQ, Radial Flipz helped shape it around what an athlete actually needs at the top of a nine-flip jump.
It worked. The Pro 9 carried the world’s first nine flips, then became the stage for BERG Record Breakers every year after.

17 m
The highest point of a single bounce. 13 m in 2022, then 17 m in 2024.
The highest trampoline jump in the world. Twice.
Set twice in the centre of Ljubljana with DD Squad, and Ernest won the competition both times.
The record is simple and brutal: the highest point of a single bounce. DD Squad build a giant trampoline across a bridge in Slovenia’s capital, hang a target over it and run a competition for the best jumpers in the world.
The clips have done billions of views online, making it one of the most viral athletic stunts of the last few years. And we’re not done. The plan is to keep going higher.
The full height record film is coming to YouTube.

Seven flips on a garden trampoline.
An Acon X, the same consumer trampoline anyone can buy, set up in Louis’s back garden.
Most garden trampolines see a few backflips at a birthday party. No custom springs, no super trampoline: just the crew, the back garden and a field of horses watching from next door. The result was the world’s first 7 flips on a garden trampoline.

Coaching the world’s first ten flips.
Twelve months coaching Canadian athlete Connor Copeland to the first ten flips in one jump.
Connor grew up on Radial Flipz videos. When Ernest stopped adding flips, Connor picked up the challenge, did the world’s second nine flips and took ten to BERG. BERG’s first call was to Ernest, to be his coach.
What followed was a year of close one-to-one coaching, a lot of it mental and plenty of it physical, much of it on location at BERG.
Louis Hillier was on the mat the whole way as a double bouncer, pad thrower and general support. Connor performed the world’s first ten flips in August 2026, and it has already done tens of millions of views online.
Our ten flips film is coming to YouTube.

The bounciest trampoline in the world.

Ernest helped BERG turn the Pro 9 into the trampoline that launched the first ten flips.
From June 2025 to August 2026 Ernest brought the design advice, the testing and the athlete’s point of view, and helped manage the project from the first ideas to the finished trampoline.
The whole Radial Flipz team, Louis and Ted Southworth included, came out to test it and push it along the way. The Pro 10 is around 70% bouncier than the Pro 9: the bounciest trampoline ever made.

Live from Record Breakers.
BERG’s yearly event for the world’s best trampoline athletes, live on YouTube with a setup we built in a month.
Our live production labelEvery year BERG flies 30 to 40 of the best trampoline athletes in the world in for Record Breakers, on the Pro 9 and now the Pro 10.
