Heart attacks, seat grabs and heel clickers will be among the tricks on show at a Nitro Circus style event which will be used to raise money for Cure Kids this weekend.

Wheels 4 Cure Kids will see more than two dozen freestyle motocross riders and BMX riders do three shows in the carpark of popular Tauranga shopping centre Fraser Cove on Saturday.

Last year's Wheels 4 Cure Kids amazed a crowd of about 5000 outside Worlds End Bar in Fraser Cove and raised $15,000.

Event organiser Luke Price said if you had never seen an event like it, it would be worth the trip down to Fraser Cove.

"I honestly think you would be blown away by what we do on our machines," he said.

"Whether it be BMX or motocross bikes, it's breath-taking and spectacular to see the boys do huge back flips only holding on to their seats. It's pretty cool and crazy stuff that we do.

"It's pretty much a Nitro Circus line-up."

Six men would be performing on their motocross bikes and at least seven would be riding BMX bikes.

Last year's event nearly raised $15,000; after show costs $9000 was donated to Cure Kids.

This year Mr Price said he hoped to donate more than $10,000 to the cause.

Mr Price said the lineup would include New Zealand's best free sport athletes including Levi Sherwood, a two times world champion free style motocross rider and Jed Mildon as commentator, who could not perform because he injured his leg a few weeks ago.

Mr Mildon was the first person in the world to do the triple and quadruple back flip on a BMX.

Mr Price would also perform himself doing "heart attacks", "seat grabs" and "heel clickers".

The day would also include live music, auctions, raffles and children's rides, he said.

"It's just a good cause, I've got two kids myself, it just feels right to support this cause."

Mr Price said a show like this would normally cost about $80 and they were offering it for a gold coin donation.

"So bring your wallets, donate and get behind this great cause because it's a bloody good one."
