Most urban commuter e-bikes are built to meet a price point — not a performance standard.

They often have high standover heights that make mounting and dismounting awkward in traffic. They offer modest torque, requiring constant downshifting and effort to climb hills. Batteries are small, limiting real-world range. Suspension is minimal or nonexistent, leaving riders to absorb broken pavement through their wrists, back, and hips. And too many are built for short-term ownership rather than long-term durability.

For serious riders — especially active seniors who want to stay strong, mobile, and independent — those compromises matter.

The Optibike G2 Metro was engineered to eliminate them.

Exclusive Power That Changes the Ride

At its core is the exclusive Optibike PowerStorm 750W continuous mid-drive motor, producing a class-leading 190Nm of torque — roughly double what most commuter e-bikes deliver.

That torque transforms everyday riding:

• Easier starts from stop signs and traffic lights — smooth, controlled takeoffs without wobble or strain
• Less shifting required — strong mechanical advantage means fewer gear changes
• Steeper hill-climbing capability — long grades feel manageable instead of punishing
• Reduced joint stress — riders can spin comfortably rather than grind, especially important for those with knee replacements or hip sensitivity

For active seniors, the moment of starting from a stop can be the most unstable part of a ride. The Metro’s torque makes that transition confident and predictable.

Mass Central Design: Stability You Can Feel

Power alone isn’t enough — balance matters.

The G2 Metro uses Optibike’s Mass Central Design, keeping the motor and battery positioned low and centered within the frame. This centralized weight distribution creates:

• Stable low-speed handling
• Solid, confident cornering
• Improved traction when climbing
• A planted, predictable feel at Class 3 speeds

Instead of feeling top-heavy or rear-biased, the Metro rides like a cohesive, grounded machine.

Range That Matches the Power

The G2 Metro is equipped with a massive 1,440Wh battery, roughly double the capacity of many commuter e-bikes. That means:

• Longer rides
• Fewer charging cycles
• Real commuting capability
• Multi-day touring potential

The Gen 2 frame redesign integrates this large battery while maintaining stability and includes a Quick-Swap battery system for riders who want extended range without tools.

Built Around the Rider

Every G2 Metro is hand-built to order in Colorado. During the ordering process, we gather rider height, weight, preferred riding position, and any additional needs so the bike arrives set up correctly.

The Gen 2 frame features a lower standover height, making mounting and dismounting easier — particularly valuable for riders managing reduced flexibility or balance concerns.

True dual suspension (150mm front travel with rear shock options) absorbs broken pavement and uneven paths, reducing impact on the spine and joints.

Seat options allow riders to fine-tune comfort for long rides — from wider, cushioned saddles for upright posture to performance-oriented designs for more active riding.

The optional dropper seatpost adds another level of confidence: lower the saddle at stop signs to place both feet flat on the ground without leaving the seat, then raise it instantly for full leg extension and efficient pedaling.

The Metro can be configured at the factory as a Class 1, 2, or 3 e-bike, or equipped with the optional MMI Multi-Mode Display, allowing riders to select between Class 1, 2, and 3 modes depending on where they’re riding.

For commuting practicality, options such as fenders and rear racks make carrying gear simple and clean. Riders can also select the optional 2700-lumen high-brightness headlight with high/low settings and a matching taillight for reliable visibility.

Why Invest in a G2 Metro?

Yes — the G2 Metro costs more than a basic commuter. But it is built to a completely different standard.

It delivers proprietary 190Nm torque, double-capacity battery range, dual suspension, centralized mass for stability, and hand-assembled quality control — all customized to the individual rider.

For many owners, it replaces car trips. It supports health and independence. It’s a machine engineered to last, not to be replaced in a few seasons.

The G2 Metro isn’t for everyone.

It’s for riders who value performance. For those who appreciate engineering. For those who plan to keep riding strong — comfortably and confidently — for decades.

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.

This is not mass production.
This is precision assembly for serious riders.

In the ebike industry, “peak power” is often used as a marketing gimmick. Many bikes claim high wattage that they can only sustain for a few seconds before the motor begins to overheat and throttle down. For the 2026 Optibike G Series, founder Jim Turner focused on a different metric: 1600W of Continuous Power when in the OHV mode on the Altus.

In this technical update, Turner explains the engineering shift required to move from the R17 platform to the G Series and why “True Power” is the only number that matters when you’re facing a 40% grade hill.

The Heat Sink

One of the most visible differences on the G Series is the massive integrated heat sink. Jim Turner points out that most European and mass-market ebikes don’t have heat sinks because they simply don’t produce enough power to generate significant heat.

“When you’re putting out 1600 watts continuous power, there’s a lot of heat coming out of the controller,” Turner explains. By mounting the controller directly to a large heat sink, Optibike ensures the G Series can maintain its full power output for the entire duration of the battery charge, even in 100-degree weather.

Continuous Power vs. Nominal Ratings

While standard ebikes are often rated at 250W or 500W, the G Series E Venture series offers a massive leap in performance:

• Optibike G Series: 1600 Watts Continuous Power.
• Standard Ebikes: 250W – 500W (Nominal/Peak).

This power allows for higher speeds and easier climbing on forest roads and steep terrain where traditional motors would stall. Because the motor is “overbuilt” for this level of output, it also boasts incredible longevity, lasting far longer than motors pushed to their absolute limits.

Torque and the “Diesel” Experience

While wattage provides the speed, 190Nm of torque provides the “chug.” Jim compares the G Series to a diesel engine; it has the raw strength to keep moving even as the hill gets steeper. This high torque means riders can stay in higher gears longer and shift less frequently, making the riding experience more intuitive and less fatiguing.

Advanced Frame Engineering

To support this level of power, Optibike redesigned the frame from the ground up:

• Low Standover Height: Using reinforced carbon fiber to provide a rigid platform that is easy for riders of all ages to mount.
• 170mm Travel: A massive amount of suspension travel packaged into a low-center-of-gravity design.
• Bolt-in Motor: A new motor housing that is easier to service, quieter to ride, and allows for shorter wiring—improving overall electrical performance.

Built for Decades, Not Seasons

Unlike the “disposable” nature of many modern ebikes, the G Series is designed to be an heirloom-quality investment. Optibike continues to service bikes built in 2008, and the G Series follows this same philosophy. The motors are designed to be rebuilt, not replaced, ensuring your bike stays on the trail for decades.

When designing the 2026 Optibike G Series, Jim Turner didn’t just want a bike that was fast; he wanted a bike that felt “rock solid” at 35 miles per hour. In a recent technical discussion, Turner revealed how the design of the rear swingarm and shock geometry has changed the game for high-performance ebikes.

For riders with previous injuries or those tackling aggressive off-road terrain, suspension isn’t just a luxury—it’s a necessity for safety and comfort. Here is how Optibike is approaching ebike suspension differently than the rest of the industry.

The Science of the Leverage Ratio

One of the most critical aspects of the G Series is the leverage ratio. Jim Turner explains that the way the shock is leveraged relative to the rear wheel determines the ride characteristic. Many lower-quality ebikes act like a “pogo stick,” offering no real damping or progression.

Optibike tuned the G Series to have a specific curve:

• Flat Performance at the Start: This keeps the bike stable and prevents “pedal bob” when you are putting power down.
• Plush Progression: As the suspension moves through its travel, it gets stiffer to absorb massive hits without bottoming out.

Stability at 35 MPH: The “Bridge of Doom” Test

A common issue with lightweight ebikes is that they feel “scary” or “twitchy” at high speeds. Brandon Mason notes that the G Series feels like a dedicated downhill mountain bike, even when hitting speeds of 35 mph.

“These bikes at 35 miles per hour, you don’t even think you’re going 35,” Turner says. “It’s rock solid. You should be feeling something, but you aren’t.”

This stability was tested on Colorado’s “Ridge of Doom,” a 45% grade route usually reserved for downhill mountain bikers. While others struggle to go down it, the G Series is engineered to ride both up and down with total control.

Packaging High Travel with Low Standover

One of the hardest engineering feats in bike design is fitting a high-travel suspension system into a frame with a low standover height. Most bikes sacrifice one for the other. By redesigning the swingarm to move backward during compression, Optibike has achieved a massive amount of travel (170mm) while keeping the bike accessible for shorter riders.

The “One Complaint” Philosophy

Jim Turner’s approach to manufacturing is famously uncompromising. He recalls a story from the early days of Optibike when he told his team he only wanted one specific complaint from customers.

“I want one complaint from people: It’s too expensive. A terrible complaint is, ‘It’s scary,’ ‘It handles like crap,’ or ‘I don’t have fun.'”

This is why every Optibike is built with top-tier brakes, wheels, and tires. There are no “garbage parts” or low-quality components. When you are traveling at high speeds off-road, the quality of your equipment is the difference between a great ride and a dangerous one.

For 20 years, Optibike has been at the forefront of the electric bike revolution. To celebrate two decades of production, founder Jim Turner has unveiled the 2026 G Series—a platform built on 30 years of design expertise and direct customer feedback.

In a recent sit-down with Brandon Mason, Jim Turner explored why the G Series isn’t just another ebike, but a high-performance machine designed to redefine the riding experience.

Designed for Every Rider: The “One Size” Philosophy

Unlike traditional bike companies that carry over “legacy” designs from road bikes, the G Series takes its cues from motocross. Jim Turner explains that standardizing the frame size allows for perfected handling.

“Standard bicycles make all these frame sizes, but a motorcycle is one frame size for a reason,” Turner says.

By utilizing carbon fiber, Optibike achieved an incredibly low standover height, making it accessible for riders from 5’2” to 6’4”. This design ensures that the bike remains agile and stable, whether you’re navigating a steep Colorado trail or a casual gravel road.

“True Power” vs. Peak Power

The market is flooded with ebikes claiming high wattage, but Turner warns of the difference between peak and continuous power. The G Series features 750 Watts of True Power.

• Optibike True Power: Continuous 750W output that won’t overheat or “poop out” on a 40% grade hill.
• Massive Torque: Delivering 190 Nm of torque, nearly double that of competitors like the Specialized Turbo Levo.

Innovative Technology: BioSmooth and Whisper Ride

Optibike isn’t just about raw power; it’s about the quality of the ride. The G Series introduces several features:

BioSmooth Technology

This technology evens out the pressure on your pedals, protecting your knees and joints. It allows riders to stay in the “aerobic zone” longer, making it an ideal tool for weight loss and fitness without the muscle fatigue typically found on conventional bikes.

Whisper Ride

Despite having double the torque of most ebikes, the PowerStorm motor is engineered for quiet operation. Through years of development, Optibike has ensured you hear the trail, not the machine.

Mass Central Design

By keeping the motor, battery, and shock low and centered, the G Series offers a “buttery smooth” and stable ride. Jim compares it to a keel on a boat, providing a stabilizing effect that prevents the bike from being tipsy at high speeds.

Built to Last: An Heirloom Quality Investment

The G Series is not mass-produced; each bike is custom-built in Colorado. From the solid billet machined parts to the dyno-tuned motors, these bikes are built to be heirloom quality.

“We’re still servicing bikes from 2008,” Turner notes, highlighting a level of longevity unheard of in the modern ebike industry. When you buy an Optibike, you aren’t just buying a product; you’re getting a machine custom-tailored to your height, weight, and riding style.

Is the G Series Right for You?

While Jim admits the G Series isn’t for the casual “around-town” rider, it is the ultimate tool for adventurers, older riders looking to keep up with younger family members, and those who have been frustrated by the limitations of mass-market ebikes.
