Power, Perfected — The Grin Technologies All-Axle Assist on Santana Tandems

Описание: Not all electric assist systems are created equal. And when you’re designing power for two riders, compromise simply isn’t an option.

That’s why Santana Tandems partnered with Grin Technologies—the most respected name in precision electric-assist engineering—to create a system that feels less like a motor and more like an extension of the ride itself.

The result is the Grin All-Axle Assist system on a Santana tandem: seamless, intelligent power delivery designed specifically for the unique demands of tandem cycling.

Unlike generic e-bike conversions, the Grin system is purpose-built. It integrates cleanly into Santana’s geometry and drivetrain, preserving the balance, handling, and ride quality that Santana tandems are known for worldwide. Power is applied smoothly and predictably, whether you’re rolling away from a stoplight, climbing sustained grades, or holding pace into a headwind.

What sets the Grin All-Axle system apart is control. Torque-based sensing delivers assistance that responds intuitively to rider input—no surging, no lag, no artificial feel. Just confident, quiet support exactly when it’s needed. For captains and stokers alike, the experience remains unmistakably Santana: stable, refined, and deeply connected.

Equally important is transparency. Grin’s open, data-driven ecosystem allows riders to fine-tune performance, monitor system health, and trust what’s happening beneath them. It’s electric assist engineered for cyclists who care about how things work—not just that they do.

Whether you’re extending your riding years, tackling bigger terrain, or simply riding farther together with ease, the Santana + Grin partnership represents electric assist done right—no shortcuts, no compromises.

Because when two riders share one bike, power should never overpower the experience.
