Honda Explores Electric Sidecar Innovation

Motorcycle sidecars have become a bit of a relic in the modern world. Though they still attract a small, loyal following, their use often comes with various handling complications. Honda’s latest development—a power-assisted electric sidecar—seeks to address some of these issues, potentially reviving interest in sidecars as a way to increase a bike’s carrying capacity. Here’s everything to know.

Sidecars were adapted for motorcycles in the early 1900s, providing a budget-friendly way to transport more passengers. However, with the rise of affordable cars in the 1950s, sidecars eventually fell out of favor. 

Today, few riders use sidecars or know how difficult they are to handle. Uneven acceleration is a problem, braking is tricky, and turning is a unique challenge. Honda’s concept, revealed through a recent patent application, offers an innovative solution: an electrically powered sidecar that addresses many of these handling issues without requiring modifications to the motorcycle itself.

Honda’s sidecar design uses load sensors on the two connection points where the sidecar attaches to the motorcycle. These sensors communicate with a control unit inside the sidecar, which manages an electric motor powering the sidecar’s wheel. The motor draws energy from batteries housed within the sidecar, and the motorcycle itself can be either gas or electric-powered without needing any direct connection to the sidecar’s control system.

When the load sensors detect acceleration from the bike, causing a yaw, the sidecar’s wheel applies power to counterbalance the forces. Similarly, if the bike slows down, the sidecar’s wheel brakes to maintain stability.

The system would also assist with cornering. For right-hand turns, the sidecar’s sensors would signal the wheel to brake, helping the bike navigate the corner more easily. In left-hand turns, the sidecar’s wheel would accelerate to counter the forces, creating a more balanced turn. While the setup doesn’t allow the bike to lean like it normally would, it should significantly improve stability.

The big question remains: Is there enough demand for an electric-powered sidecar? Although the patent application shows Honda’s interest in exploring the concept, it’s uncertain if the idea will progress beyond the drawing board. However, the company’s investment in this solution hints at intriguing possibilities for the future of motorcycle sidecars.
