Thunderbike

What Thunderbike does

Thunderbike is a German Harley-Davidson contract dealer and custom motorcycle builder headquartered in Hamminkeln, North Rhine-Westphalia. Founded in 2006 by Andreas Bergerforth as a sole proprietorship (e.K.), the company operates an integrated business combining official new and used Harley-Davidson sales, bespoke custom bike manufacturing, proprietary aftermarket parts production, full-service workshop operations, financing, rental, and a branded apparel and accessories retail operation. Its customisation work spans distinct stylistic lineages — notably Chicano lowrider builds on Heritage Softail platforms, Fat Boy and Breakout custom series, vintage Evolution Big Twin restorations, and Shovelhead-era builds — with dozens of named documented projects serving as both portfolio and marketing collateral.

The company's core technology rests on in-house vertical integration: a production facility housing construction and design, CNC machining of aluminium, metal fabrication (Metallbau), and surface finishing (Oberflächenveredelung). Proprietary Thunderbike Parts — including the Big Speed Rad (5 double-spoke, 18–23 inches), Gothik Rad (4 double-spoke, 18–21 inches), Vegas-design pulleys, single-side swingarm kits, air ride suspension systems, El Dorado fork crowns, and bespoke rear fenders — are TÜV-certified for German and EU road registration, an important regulatory differentiator. The KLIKTRONIC electronic gear shifting system is integrated via a proprietary aluminium mounting bracket designed in-house.

Thunderbike monetises through eight primary revenue streams: new Harley-Davidson motorcycle sales (manufacturer retail pricing), used motorcycle sales, custom bike manufacturing and bespoke commissions, proprietary parts wholesale and e-commerce (shop.thunderbike.de), Harley-Davidson original accessories resale, branded and general apparel/accessories retail, service and repair work, and motorcycle rental and financing. Distribution operates through the Hamminkeln showroom and service facility, a proprietary e-commerce platform, an independent dealer network ('Thunderbike Dealer vor Ort') across Germany and beyond, the on-site Thunderbike Roadhouse hospitality venue, and an active events portfolio (Rumble & Thunder, Jokerfest, Late Summer, Kick-Off, Grand Nicholas) supported by participation in major European rallies including European Bike Week Faak and Custombike Show Bad Salzuflen. Primary customer segments are Harley-Davidson enthusiasts and collectors (SMB/individuals), a B2B dealer channel, and general motorcycle retail customers — with international bespoke commissions extending reach beyond the DACH core market.

Broad incumbents

• Küryakyn: Large US aftermarket manufacturer of motorcycle accessories and custom parts for Harley-Davidson, Indian, and metric cruisers. Comparable in that it supplies a wide, branded catalogue of cruiser customisation parts through dealer networks, similar to Thunderbike Parts.
• S&S Cycle: Established US manufacturer of V-twin performance engines, exhausts, and drivetrain components for Harley-Davidson. Comparable as a long-standing, broad-line V-twin aftermarket brand that competes with Thunderbike's proprietary parts in the same enthusiast channels.

Direct peers

• Roland Sands Design: US-based performance and custom motorcycle brand founded by a former racer, producing both complete custom builds and a large proprietary aftermarket parts catalogue (wheels, brakes, exhaust, suspension). Comparable as a custom-H-D-style house with a strong in-house parts brand.
• Rick's Motorcycles: German-based Harley-Davidson custom shop and parts manufacturer with its own in-house production and dealer network. Operates in the same premium cruiser-customisation niche as Thunderbike, competing head-to-head for the German and European custom H-D customer.
• No Limit Custom: Dutch/German custom Harley-Davidson builder producing its own line of CNC-machined custom parts, fenders, and exhausts, with TÜV approval. Directly comparable in business model (custom builds + proprietary parts + dealer sales) and customer base to Thunderbike.

Regional players

Comparable as the B2B distribution layer that Thunderbike's dealer network interacts with and competes against for shelf space.
