Announcing the Optibike G2 Altus: The Ultimate Hand-Built E-Venture Bike
The Agile, Custom-Tailored Brother of the Legendary R22 Everest
For years, the Optibike R22 Everest has stood as one of the rarest, most capable high-performance electric mountain bikes in the world. Built in small numbers and engineered without compromise, it was designed for riders who demand extraordinary performance and uncompromising quality.
Now, we are proud to introduce its more agile sibling: The Optibike G2 Altus.
The Altus brings our premium engineering philosophy into a dynamic, mountain-focused platform. It delivers serious torque, long-travel suspension, and full custom adaptability in a nimble, carbon fiber chassis.
This is not just another mass-produced e-MTB. It is an E-Venture.
What Is an E-Venture? Coining a New Era of Electric Biking
Most electric bikes on the market today are built around restrictions and mass-market compromises. They are locked into a single regulatory class, choked by software limits, and built with cheap components designed to hit a price point—not to last.
We coined the term E-Venture for a completely different class of machine.
An E-Venture bike is a premium, high-performance electric adventure bike built for riders who refuse to be limited by bike paths. It is designed for those who want to cover serious distance across real, rugged terrain without sacrificing comfort or control.
America’s landscapes are vast. We have:
- Millions of acres of BLM and Forest Service land with endless OHV trails
- High, demanding mountain passes
- Remote desert plateaus
- Long, steep backcountry climbs where a standard e-bike motor would quickly overheat
The E-Venture platform was engineered for this exact reality. It blends the capability of a high-end electric mountain bike with intelligent adaptability and hand-built reliability.
Hand-Built and Custom-Tailored to You
When you reach a certain point in life, you stop settling for “off-the-rack.” You know the value of precision engineering and equipment that works exactly the way you need it to.
Unlike mass-produced bikes, every Optibike G2 Altus is hand-built and custom-tailored to the individual rider. We understand that a 6’2″, 220lb rider has vastly different needs than someone who is 5’9″ and 170lbs.
When you order an Altus, it is custom-built to suit your specific body mechanics and riding style. From dialing in the premium long-travel suspension to match your exact weight, to optimizing your riding position to eliminate joint stress and lower back fatigue, your Altus is a bespoke machine built specifically for your next adventure.
MMI: The System That Puts You in Control
At the core of every E-Venture model is Optibike’s proprietary MMI (Multi-Mode Interface) system. MMI changes everything by giving the power of choice back to the rider.
Instead of being permanently locked into a single legal class, you select the appropriate operating mode for your environment:
- Class 1 (Pedal assist only, 20 mph limit)
- Class 2 (Throttle active, 20 mph limit)
- Class 3 (Pedal assist, 28 mph limit)
- High-Power Off-Road Mode
One premium machine. Multiple legal personalities. Traditional e-bikes dictate what you cannot do. The Altus allows you to adapt to wherever the trail takes you.
Off-Road Mode: A True Moto-Style Experience
When riding on private land or across America’s 18,000+ miles of remote OHV forest roads, the Altus unlocks its full Off-Road capability:
- 1600 watts continuous power
- 2400 watts peak output
This delivers a distinctly moto-style feel. You get immediate acceleration and powerful, sustained climbing authority that turns grueling, steep grades into a thrilling ride. It doesn’t just give you a short-lived burst of power; it provides real, sustained momentum designed for long climbs and loose terrain where true capability matters.
This is the essence of an E-Venture. It protects your knees, expands your range, and lets you conquer mountains on your own terms.
Premium Suspension and Agile Performance
Where the Everest dominates extreme expedition riding, the Altus brings that same E-Venture DNA into a highly agile, aggressive mountain platform. It climbs fiercely, descends with absolute confidence, and remains perfectly composed at high speeds.
The G2 Altus Delivers:
- 170mm front and rear premium suspension travel (custom-tuned to your weight)
- A lightweight, ultra-strong carbon fiber frame and swingarm
- Mass-centralized battery placement for a perfectly balanced center of gravity
- An upright, customizable geometry designed for all-day riding comfort
A Drivetrain Built for Real Power & Zero Headaches
We know that a broken derailleur in the backcountry ruins a weekend. That’s why the Altus features the legendary German-engineered Rohloff Speedhub 500/14 14-speed internal gear hub.
This bulletproof system provides:
- Sealed internal gearing that is impervious to mud, dust, and rock strikes
- Exceptional durability under high-torque loads
- A perfect, straight chain line that drastically reduces wear
- A massive gear range to conquer the steepest American landscapes
When you invest in a custom-built e-bike, drivetrain integrity is not optional. The Rohloff system aligns perfectly with the E-Venture mission: zero maintenance headaches, flawless performance, and lifetime reliability.
The Evolution Continues: Start Your E-Venture Today
The Everest proved what was possible. The G2 Altus expands that vision, bringing the custom-built E-Venture platform to discerning riders who want intelligent adaptability, plush suspension, and uncompromising American-built performance.
It’s not about riding within the limits of a mass-market toy. It’s about choosing a machine that expands your limits.
That is the E-Venture promise.
