Sean McKinney

Everybody in flatland circles just calls him "Spinny." Sean McKinney came up through the Southern California freestyle scene at the tail end of the 1980s, rode the American Flatland League and International Flatland League pro tours through the 1990s and 2000s, and designed a frame — the S&M Sabbath — that's still one of the more collectible freestyle frames of its generation. He's been on staff at S&M Bikes since March 1996, longer than most riders stay with any single sponsor in BMX, and he still gives the factory tours.

A teenage job at La Palma Cycle Center

Born December 11, 1971, McKinney started riding twenty-inch bikes as a kid and picked freestyle over racing around age 13. At 13 or 14 he was hired at La Palma Cycle Center, working alongside Bill Ryan, Turnell "Tuni" Henry, Tommy Brackens and Kevin Hull — Bill Ryan calls him the shop's go-to freestyle grunt (source: Bill Ryan, firsthand, 2026). McKinney told a version of the same story himself in an April 1997 interview with Ride BMX UK, reproduced by 23mag.com: "I was 15 years old, needed a job, had to pay for some stuff. I got hired at a bike shop where I worked with Turnell Henry, Tommy Brackens, Kevin Hull and Bill Ryan. They hired me into this store and I worked with a bunch of pro-racers."

That's not a sponsorship or a team connection — it's a teenage bike-shop job that happened to put McKinney on the sales floor next to working pros. The shop went under, by his own account, precisely because it was staffed by riders instead of businesspeople. When La Palma Cycle Center closed, McKinney moved with Bill Ryan to Power Plus Cycles, Ryan's own shop in Stanton, then landed at Los Alamitos Schwinn, where he worked from about 16 until 21, the last few years running the place (source: Bill Ryan, firsthand, 2026). From there his path ran through Tip Plus and into S&M Bikes — both covered below. That run through the retail side of the industry — shop floor, then a distributor — is the foundation he built the rest of his career on.

Flatland Fugitives and the early-1990s L.A. scene

McKinney rode with the Flatland Fugitives, a Los Angeles-based crew whose videos are still cited as a formative document of early-1990s flatland. He appears in the 1993 video West Coast 4130 and in the group's self-titled Flatland Fugitives tape alongside Day Smith, Edgar and Ivan Plascencia, Andrew Arroyo, Nate Hanson, Jesse Puente and others. Contest footage from the period — the 1994 Bicycle Stunt (BS) series stops in Oklahoma City, Moreno Valley and Chicago, and the 1995 Mysterious contest in San Bernardino — has him lined up next to Dennis McCoy, Jay Miron, Trevor Meyer and the rest of the era's flatland field.

His first major result on record: 7th place in the stuntmen flatland division at the 1994 BS Series round 3 in Oklahoma. That same year he rode the Freestyle World Championships in Cologne, Germany.

Working the industry side while he rode — Primo, 1995

McKinney's day job kept overlapping with his riding career. By the mid-1990s he was working at TIP Distributing, home of the Primo components brand, alongside friends Nate Hanson and Day Smith. In that same 1997 Ride BMX UK interview, he took credit for pushing Primo into freestyle-specific product — starting with the V-Monster tire, which he and Smith spec'd out directly with the Cheng Shin tire factory in Taiwan: tread pattern, sidewall thread count, rubber compound. "We gave them the whole scoop," he said. The relationship was rockier than the product was good — McKinney was blunt in the interview about feeling like sponsored riders were treated as expendable once the products started selling — but the V-Monster tire and the freestyle line that followed became a real part of Primo's catalog in the 1990s.

1996 — Joining S&M Bikes and designing the Sabbath

In March 1996, McKinney got hired at S&M Bikes, working directly under founder Chris Moeller. He handled sales and warranty. Moeller also handed him a bigger assignment: design a freestyle frame to replace S&M's existing Heavy As F**k model, which McKinney thought was a "pile of shit."

The result was the S&M Sabbath. McKinney worked with fellow rider Sean White — who had designed the Morales frame — to turn the spec into real blueprints rather than a rough sketch handed to a machine shop. Production ran through a manufacturer in Northern California, and McKinney has said he made the eight-hour drive up there roughly ten times over the course of 1996 to keep the tooling and welds on track. He deliberately kept his name off the frame graphics — no signature model, just "the Sabbath" — wary of the whole thing turning into a vanity product if it flopped. It didn't. The Sabbath's rear-wheel and brake clearance, which let riders run the wheel anywhere in the dropout without rubbing, became one of its signature details, and the frame shipped in 1997.

The Ride BMX UK cover story on McKinney that ran in April 1997 — timed to the Sabbath's release — was, per 23mag's archive, the longest interview the magazine had run to that point, more than 7,000 words.

The AFL/IFL years — 2000 and 2001

McKinney kept competing into the 2000s on the American Flatland League and its successor, the International Flatland League — the tour Chris Day, Jason Pischke, Sam Peterson, Chad Johnston and Brian Sofer built starting in late 1999. Documented pro-class results include 11th place at AFL Round 1 in Harbor City, California, on March 11, 2000, and 8th place at AFL Round 4 in San Francisco on November 4, 2000. He's also listed as a team rider on the S&M-era roster alongside Matt Beringer in an early-2001 team advertisement.

Revenge Industries, 2002

McKinney launched Revenge Industries at Interbike in 2002 — a component brand operating under the S&M umbrella, built around tires, brakes, grips and a complete 26-inch cruiser. It reached mail-order shelves through major BMX distributors from roughly 2003 through 2008. It was McKinney's own outlet as head of S&M's customer service department, and it ran on the same "sweat the small stuff" approach he'd applied to the Sabbath.

Still at "The Building"

McKinney remains on staff at S&M Bikes' Santa Ana headquarters — riders and staff call it "The Building." He's given factory tours documented on video, and he runs "Flatland Fridays," informal jam sessions held at S&M's warehouse. He was profiled again in 2012 by Twenty Inch on the state of modern flatland, and appeared in a 2013 Ride BMX/TransWorld BMX "Industry Insiders" feature. S&M's own site still marks his birthday every December with a running joke about whether he'll show up to work the next day.

These days McKinney lives in Hawaii. Bill Ryan says he still calls to check in with the old La Palma crew every week (source: Bill Ryan, firsthand, 2026).

Why McKinney matters to BMX

Two things. First, the Sabbath — a frame designed by a rider who'd spent a decade watching what broke on cheap freestyle equipment from behind a bike shop counter, and who built that knowledge into the geometry. Second, staying power: 30 years at one company, in an industry that has swallowed most of the brands that started out alongside S&M in the late 1980s and early 1990s. McKinney rode flatland at a high level through the sport's leanest commercial years and then helped keep one of its most durable brands running from the inside.
