Beyond the Ebike: A Deep Dive into the Optibike R22ET Everest
For decades, Jim Turner has been engineering electric bikes that push the boundaries of physics. His flagship creation, the R22ET Everest, remains the gold standard for a category he calls “E-Venture”—a machine designed for long-distance exploration and high-altitude performance that effectively eliminates range anxiety.
In a technical discussion in Paonia, Colorado, Turner and Brandon Mason discussed how the R22ET Everest is built to outlast the rider, even in the most demanding conditions in the world.
300 Miles of Freedom: The Dual-Battery System
The defining feature of the R22ET Everest is its industry-leading 300-mile range.
“I don’t want to get in my car,” says Turner. “I want to ride to the trail, ride the trail, and ride home.”
The R22ET Everest achieves this through a 3.3kWh dual-battery system. This “Out and Back” technology features a physical switch, allowing the rider to deplete the first battery and keep the second in reserve for the return journey. With nearly five times the capacity of a standard electric mountain bike, the Everest is a tool for true adventurers.
The MMI “Transformer” Interface
The R22ET Everest is a “chameleon,” capable of adapting to different legal jurisdictions and terrains via the Multi-Mode Interface (MMI). This allows the rider to configure the bike on the fly:
- Class 1, 2, and 3: Limits the bike for legal use on multi-use trails and roads (up to 28 mph).
- Moto Mode: Unlocks the 2500W peak potential of the motor for off-road use on forest service roads, reaching speeds up to 36 mph.
This flexibility ensures that you can commute at high speeds to a trailhead and then switch to a legal trail mode once you arrive.
“True Power” Performance vs. The Industry
Performance on the R22ET Everest is measured by True Power—the ability to maintain 1700W of continuous output without overheating or “conking out” on steep grades.
- Continuous Power: 1700 Watts.
- Peak Power: 2500 Watts.
- Torque: 190 Nm (Nearly double the torque of a top-end Specialized bike).
Billet Aluminum and “Heirloom Quality”
The construction of the R22ET Everest sets it apart from mass-produced ebikes. While the frame is carbon fiber, the battery case is machined from solid billet 6061 aluminum. This racing-motorcycle approach to engineering provides incredible stability at 35 mph and ensures the bike can be serviced and rebuilt for decades.
By utilizing Mass Central Design, Optibike keeps the battery weight low and centered. This design enhances handling, acting like a keel on a boat to stabilize the bike as you navigate technical single-track or high-speed gravel roads.
