Rider is an Indonesian apparel and underwear brand best known for men’s underwear, singlets, and everyday basics. It operates under PT Mulia Knitting Factory, a family-owned textile manufacturer established in 1955. Unlike many contemporary fashion labels that outsource production, Rider’s identity is rooted in decades of vertically integrated manufacturing within its parent company [1].

Note: This article refers to the RIDER underwear and apparel brand from Indonesia. It is distinct from other unrelated products or entities sharing the “Rider” name.

Rider is recognized as one of PT Mulia Knitting Factory’s two strongest domestic men’s underwear brands, alongside SWAN BRAND [2].

1955: Establishment

The origins of Rider trace back to the founding of PT Mulia Knitting Factory in 1955 by Phan Tjen Kong. The company began operations as a garment factory specializing in men’s underwear, producing early brands including PIPE’S, APPLE, SWAN BRAND, and RIDER. Consequently, the Rider label has been integral to the company’s manufacturing history since its inception rather than being a later retail addition [3].

1967–1979: Second and third generations

In 1967, Max Mulyadi Supangkat, the founder’s son, joined the business as the second generation of leadership. During his tenure, the company expanded its garment exports to Europe, the United States, and Canada. Domestically, Max broadened Rider’s distribution network, establishing it as a market leader in Indonesia [4].

The third generation, represented by Henry Supangkat, entered the company in 1979. Under Henry’s direction, Mulia Knitting Factory evolved from a garment assembly operation into a comprehensive textile manufacturer with capabilities spanning knitting, dyeing, yarn spinning, and garment production [5].

A defining characteristic of Rider’s corporate development is its vertical integration. In 1984, Mulia Knitting Factory constructed a new facility on approximately 70,000 m² of land in Jakarta, equipping it with machinery imported from Japan and Europe [6].

To secure raw material supply, the company established PT Mulia Spindo Mills in 1989 as a dedicated spinning operation. This created a fully integrated production chain:

Cotton/yarn → spinning → knitting → dyeing/finishing → garment manufacturing → finished Rider product

This structure allowed the group to maintain strict control over fabric quality and production consistency, factors critical to the comfort and durability of basic apparel such as underwear [7].

During the economic crisis of 1997–1999, Mulia Knitting Factory prioritized its export market while upgrading its integrated facilities to meet international standards. This export-oriented strategy was vital for sustaining operations during a difficult period for the Indonesian economy [8]. As a result, the company developed a dual identity: a strong domestic consumer brand and a competitive export-manufacturing business.

The fourth generation of the founding family entered the business in 2004. Hanan Supangkat, son of Henry Supangkat, took a leading role in the development, marketing, and distribution of Rider’s men’s underwear line [9].

Under this new leadership, the company placed greater emphasis on Rider as a consumer brand. Initiatives included the “RIDER Living Healthy” positioning and product innovations such as RIDER Anti Bacteria, which utilized Swiss technology and became a significant marketing campaign [10].

Historically, Rider has positioned underwear as an essential everyday product rather than primarily a fashion statement, encapsulated by its long-running slogan:

“The Power of Underwear”

While maintaining this core association, the brand has expanded into broader lifestyle categories. The official website currently categorizes Rider Styles into:

• Active
• Classic
• Lifestyle
• Premium
• Sport [11]

This reflects a wider positioning where Rider serves as both a specialist underwear label and a provider of men’s lifestyle basics.

While men’s underwear remains the core offering, Rider’s manufacturing scope is extensive.

Underwear

• Briefs
• Sport underwear
• Other men’s underwear styles
• Anti-bacterial underwear
• Children’s underwear

Apparel

• Singlets
• T-shirts
• Polo shirts
• Men’s apparel
• Women’s apparel
• Children’s apparel

Beyond finished garments, the company also manufactures cotton yarn and knitted fabric [12]. The official domestic brand portfolio comprises:

Rider distinguishes itself through substantial in-house textile manufacturing. The company lists its primary production location as Jakarta with the following assets:

• 1,600 employees
• 32,000 spinning spindles
• 150 knitting machines
• 70 dyeing & finishing machines
• 750 sewing machines

Stated monthly production capacities include:

• 250,000 kg of knitted fabric
• 100,000 dozen knitted underwear
• 10,000 dozen T-shirts
• 10,000 dozen polo shirts [14]

This vertical manufacturing structure remains a key competitive advantage for the brand.

Rider products predominantly utilize Australian cotton, with most items described as 100% cotton [15]. This material choice aligns with the brand’s traditional focus on comfort, breathability, durability, and practical design for everyday wear. Functional innovations, such as the Anti Bacteria range, complement this cotton-centric philosophy [16].

Indonesia is central to Rider’s identity and commercial success. The brand maintains a wide distribution network across major retailers and department stores, including Matahari, Hypermart, Indomaret, Alfamart, Ramayana, Metro, SOGO, AEON, and Yogya [17].

Additionally, Rider operates dedicated House of Rider retail showrooms in locations such as Jakarta, Bekasi, Palembang, Surabaya, and Pekanbaru. Distribution has further expanded into online commerce channels.

Although strongly identified with Indonesia, the parent company’s operations extend globally. Export markets include the United States, Canada, Europe, Asia, and Japan. The company has also manufactured products for international brands such as Polo Ralph Lauren, Tommy Hilfiger, OshKosh, Antigua, and PVH [18].

It is important to distinguish between Rider as a consumer brand and Mulia Knitting Factory as an export manufacturer; while related, they serve different market segments.

Readers should differentiate between two related but distinct entities:

RIDER

The RIDER underwear and apparel brand is associated with PT Mulia Knitting Factory and is primarily known to consumers for its clothing products [19].

Rider Group

Rider Group is a broader corporate conglomerate with interests extending beyond consumer apparel into textile manufacturing, retail, agriculture, trading, and military and police equipment. These diverse businesses share a common corporate history and values [20].

The business has progressed through four generations of family leadership:
