1904
The NSU Neckarsulmer 4 PS, introduced in 1904, marks a significant milestone in motorcycle history. Emerging from a nascent industry, this early model helped shape the future of two-wheeled transportation. While other manufacturers were experimenting with motorized bicycles, NSU aimed for a more purpose-built machine. A direct competitor in this era was the similar sized and powered Hildebrand & Wolfmüller, though the NSU offered a different approach to engine placement and overall design.
Powering the Neckarsulmer 4 PS is a single-cylinder, four-stroke engine displacing 482.0 ccm (29.41 cubic inches). This engine, while modest by modern standards, was sufficient to propel the motorcycle to a top speed of 70.0 km/h (43.5 mph). Fuel capacity is a reasonable 9.00 litres (2.38 US gallons), allowing for a decent range before refueling. The motorcycle itself is relatively lightweight, tipping the scales at 80.0 kg (176.4 pounds), which contributes to its manageable handling characteristics.
Given its age, the riding experience on the Neckarsulmer 4 PS is undoubtedly unique. Forget about modern suspension and braking. This machine requires a hands-on approach, demanding constant rider input and awareness. The upright riding position offered a clear view of the road ahead, essential given the limited stopping power. Comfort was likely a secondary consideration in its design, with a focus on basic functionality over luxurious amenities. Expect a direct connection to the road and a raw, unfiltered motorcycling experience.
The NSU Neckarsulmer 4 PS was primarily targeted towards individuals seeking a practical and relatively affordable means of personal transportation in the early 20th century. It would appeal to those fascinated by the pioneering days of motorcycling and who appreciate the mechanical simplicity of early machines. It's a piece of history that provides a tangible link to the origins of modern motorcycles. While not a machine for everyday commuting in today's world, the Neckarsulmer 4 PS offers a glimpse into the past and an appreciation for the progress made in motorcycle design over the last century.
✅ Why buy this bike?
• Simple and robust single-cylinder engine design allows for relatively easy maintenance and repair, crucial for early motorcycles. • Direct belt drive provides a simple and efficient power transfer, minimizing mechanical losses compared to more complex systems. • Lightweight construction contributes to nimble handling and maneuverability, especially beneficial on unpaved roads common in that era. • The 4 PS engine, while modest, offered sufficient power for solo transportation, exceeding the capabilities of bicycles. • The minimalist design and lack of complex components made it relatively affordable compared to other early motorized vehicles. • Its historical significance marks it as an important early example of motorcycle engineering and a pioneer in personal transportation.⚠️ Things to consider
• The single-cylinder engine produces significant vibration, leading to rider fatigue on longer journeys. • The belt drive system is susceptible to slippage in wet or muddy conditions, reducing traction and power delivery. • Limited braking capabilities pose a safety concern, especially at higher speeds or on downhill gradients. • The lack of suspension results in a harsh and uncomfortable ride, particularly on rough surfaces. • Starting the engine can be challenging, often requiring manual effort and potentially resulting in kickback.Rule of thumb: under 125cc / 15HP → A1, under 47HP → A2, above → A.
