The world’s most sophisticated micro-mobility vehicle

Announced in 2022, the Bo M is now engineered for production with hundreds of design advancements to bring more performance, reliability, and quality, all within a form that stays true to the Bo M concept revealed last year. With the final specification and production prototypes now complete, the Bo M showcases a focus on robust and intuitive features, designed in order to improve every journey. It utilises the unique Bo Safesteer technology to create a smooth and stable ride, combined with category-leading motor torque and power ratings, and functional innovations to deliver a sophisticated riding experience.

Bo was founded by two engineers, formerly of Williams F1 Advanced Engineering, and a Jaguar Land Rover designer, giving the company a fundamental understanding of vehicle dynamics and manufacturing, which has been uniquely applied to the Bo M, the first product in a transformative range of Bo lightweight electric vehicles.

Bo Co-Founder and CEO Oscar Morgan said: “Moving to production is a momentous moment for our company. The entire Bo team has worked tirelessly with a common aim; to create a product that will consistently delight our riders. The team has been focused on developing game-changing features, like our Monocurve chassis with integrated Lock and Load hooks, and safety enhancements such as Safesteer, whilst using our experience in automotive design to build visually exciting vehicles people feel proud to own and ride. We are excited to see the culmination of these efforts within the Bo M and I cannot wait for our first riders to take delivery of their M later this year.”

Following 24 months of development and engineering refinement, the Bo M enters production with a raft of technological features and advancements all designed to ensure every rider gets the maximum possible enjoyment from each journey. These improvements include a 100% increase in the chassis strength, and an increase in peak power output from 1,000W to a category-leading 1200W. There has also been further developments with the lighting system, with a maximum headlight power increased to 800 lumens, the addition of automatic temperature control, as well as signature start up and power off light animations. The main chassis section has been retooled, increasing the width for improved ergonomics and battery capacity. This allows for extended range and an even more comfortable stance when riding. 

Bo Safesteer

Safesteer technology is a world-first in micro-mobility vehicles, a dynamic steering stabilisation system developed by Bo to set the benchmark for control and inspire rider confidence. This patent-pending technology, fully integrated within the Bo chassis, assists, and stabilises the steering through bumps, dips, and potholes to keep the rider in perfect comfort and control. Novice and experienced riders often cite stability as their primary concern when riding over mixed terrain. Bo’s Safesteer technology gives a seamless, stable ride and builds confidence at every turn, allowing everyone to enjoy the ride.

Safesteer will deliver the smoothest and most stable ride while at the same time achieving a new benchmark in mechanical simplicity and reliability. The system is based on opposing force from a pair of bespoke wound torsion springs, housed within a unique Bo mechanism that delivers predictable steering correction up to a 50° turn angle. This system works to recreate the natural centring dynamic of a larger wheel and smooth the ride to give Bo riders an exceptional experience every time.

Monocurve chassis and design

Bo’s Monocurve chassis represents a foundational shift in vehicle design and engineering – the single greatest sector advancement since electric scooters arrived in our cities. Alongside strength and reliability, Bo M’s chassis has been designed to enable the integration of multiple sector-leading innovations without adding complexity for the user. Forged from high-strength aluminium, the chassis is revolutionary in the category.  The intuitive, unbroken lines of the Monocurve chassis create the first unibody structure in this sector, designed to true automotive principles, seamlessly combining function with design. The design allows for the steering to be separated from the chassis, forming a robust mounting point for the Lock and Load cargo solution whilst also providing a strong and stable platform for Bo riders.

The precision engineering approach is equally evident on the Bo M’s geometry, which is optimised for stability and ergonomics. Technical features include a wider handlebar at 580mm, a generous 930mm wheelbase for more standing room and relaxed riding handling, and a 76° steering angle for naturally controlled dynamics.

Bo Co-Founder and CCO, Luke Robus said: “We believe in the pursuit of simplicity. From the early sketches to prototypes and through to these pre-production models, the M’s lines come together without complication. This is testament to the rigorousness of our first-class engineering team integrating all the technology we've packed into the M. Never cluttering, or getting in the way of the product's purpose, instead celebrating this newfound simplicity with a design language you'll see in evidence across the range of lightweight EVs we have planned for the future.”

Lock and load

Bo’s all new Lock and Load system is incorporated within the Monocurve Chassis and features dual purpose revolving hooks that act as both secure locking points for the vehicle as well as stable cargo carrying solution. With the hooks mounted through the core structure of the chassis, cargo of up to 10kg can be securely carried, negating the need to hang anything on the handlebars or risking bag swing disrupting the steering, increasing the safety, control, and comfort of each ride. Additionally, the Lock and Load system is magnetically secured, so when not in use as a locking point or cargo loading, they can be spun 180° and hidden within the steerer, preserving the clean lines of the chassis.

Airdeck

Introducing an intelligent, lightweight, and invisible comfort system, the Airdeck, an engineered elastomer footpad, has been created from 11mm EVA anti-vibration foam based on the same material technology found in high performance running trainers. The lightweight deck panel is tuned to reduce road vibrations, removing the need for complex, heavy and largely ineffective suspension systems and increasing the rider’s comfort on longer rides by isolating the feet from any vibrations that result from the road surface.

Performance

Showcasing a blend of performance and elegance, the Bo powertrain features a high torque motor, providing a peak power output of 1,200W and a top speed of up to 35km/h (21mph), with a battery capacity of 655Wh delivering a range of 50km. The Bo team is based out of Bristol, a famously hilly city in the UK, and ensuring hill-climbing performance was a core requirement of the powertrain development programme. The bespoke high current electric motor has been optimised for mid-range torque, maximising efficiency across the broadest rpm-range possible, and the precision throttle map allows for excellent control of output of power and responsiveness. Tested on hills up to 22.5°, this performance specification results in silent, controllable acceleration, with the necessary power to take on the most challenging of roads.

Braking

Bo M features a powerful, low maintenance braking system, with a regenerative e-brake located in the rear wheel, controlled by the left brake lever, adding energy back into the battery under braking and a front sealed drum brake controlled by the right brake lever. The two brake levers give the rider highly intuitive control over which brake to use and when, depending on the situation and the desired feel. They can choose to only use the strong and futuristic-feeling e-braking, or the front drum brake, or both if they need to stop quickly. This gives the rider full control when slowing and stopping and is simple and familiar.

Daytime Running Light (DRL)

With safety in mind Bo’s distinctive Daytime Running Light (DRL) wraps around the Monocurve chassis to create Light Halo, a world-first in the sector, which delivers 270° light visibility. This signature design dramatically increases road presence and awareness from other road users by ensuring both the Bo M and rider are visible from every angle. Complementing the Light Halo, a powerful headlight with up to 800 lumens from three temperature-controlled LED lights housed in an aluminium enclosure, illuminates the road ahead, while a wide-angle high-lumen rear light keeps riders visible from behind in all weathers, flashing brightly under braking.

Bo Co-Founder and CTO Harry Wills said: "Our rider research discovered the majority of people seldom or never fold their e-scooters, so we made a conscious decision to introduce the Bo M with an unbroken Monocurve unibody chassis and eliminate this source of weakness. We’ve packed the M with technology that enhances the rider experience, but tailored to exactly what is needed as a lightweight electric vehicle you can use every day. There are no superfluous gadgets or gizmos that can compromise reliability or detract from the riding experience.”

Bo M is the first in a series of models, with more details to be announced in the coming months. First pre-order deliveries are due to start from November, with further units available from February 2024.
