Please note: The Bonnell 805 RX is a closed-course, high-performance machine intended strictly for off-road use.

The foundation of the Bonnell 805 RX is engineered around absolute structural rigidity, low unsprung weight, and centralizing mass to achieve unparalleled handling characteristics on tracks and trails alike.

Unlike lightweight electric trail bikes that rely on modified downhill mountain bike frames, the 805 RX is built around a heavy-duty, forged aluminum main frame. This frame structure is robotically welded and stress-tested to absorb the severe impacts of triple jumps, deep whoops, and high-speed rock gardens. The twin-spar configuration cradles the heavy electrical components low in the chassis, bringing the center of gravity downward to make the bike feel incredibly light and "flickable" mid-air.

The bike features a highly aggressive, modern dirt bike geometry layout engineered to bridge the gap between tight trail agility and high-speed stability:

The rear swingarm utilizes hydroformed aluminum to maximize lateral rigidity while allowing a calculated amount of vertical flex. This engineered flex works in harmony with the rear suspension to provide maximum traction when accelerating out of loose, muddy corners under full torque load.

At the heart of the Bonnell 805 RX lies a cutting-edge electric powertrain that provides linear, instantaneous torque without the lag, heat, or maintenance of a traditional combustion engine.

The bike is propelled by an advanced Interior Permanent Magnet (IPM) liquid-cooled synchronous motor. Capable of spinning up to an impressive 12,000 RPM, this motor delivers smooth, unrelenting power across its entire rev range.

The 805 RX features a smart, modular battery bay located directly under the seat. Utilizing a standard 3.9 kWh Core Battery pack packed with ultra-high-drain cells, the entire unit can be unlatched, lifted out, and swapped for a fresh pack in under 15 seconds without the need for a single tool.

To cater to different riding environments, the Bonnell 805 RX is engineered with a modular primary drive setup:

The massive raw power of the Bonnell 805 RX is harnessed and directed by a proprietary EBMX-tuned digital control interface, turning raw electricity into precise, usable traction.

The brain of the electronics suite is the state-of-the-art EBMX X30 sine-wave controller. Operating on high-efficiency field-oriented control (FOC) algorithms, it processes throttle inputs thousands of times per second to guarantee crisp, predictable power delivery without any digital lag.

Riders can manage the machine's behavior mid-ride via intuitive, thumb-accessible handlebar switches paired with a vibrant dashboard display:

Through the official Bonnell companion application (available for iOS and Android), riders can connect to the bike via secure Bluetooth to completely rewrite its riding characteristics:

Power means nothing without control. The 805 RX features race-grade mechanical components to ensure it grips, stops, and dampens flawlessly over the harshest terrain.

The suspension package features premium Sirris A-Kit components, fully adjustable for high/low-speed compression and rebound damping:

To bring a 56 hp machine to a halt, the 805 RX uses an overbuilt hydraulic braking system:

The 805 RX rides on a traditional, full-sized motocross wheel and tyre configuration to maximize trail rollover and footprint traction:

For riders seeking an exact look at the geometry, electrical engineering, and performance thresholds of the Bonnell 805 RX, the following matrix breaks down every official specification:

A: The first production batch of the Bonnell 805 RX is scheduled to arrive at our Patriot Bikes Wakefield showroom in Late October 2026. Because these bikes are in high demand across Europe, there is an estimated 6-week delivery wait time from the moment you secure your pre-order slot. We highly recommend placing a deposit early to lock in your build from the incoming shipping container.

A: No. The Bonnell 805 RX is engineered exclusively as a high-performance, closed-course competition machine. It does not feature indicators, mirrors, a registration plate bracket, or road-legal lighting arrays. It is intended strictly for use on private land, dedicated motocross tracks, and closed enduro circuits. Attempting to ride this model on public highways is illegal.

A: The bike ships directly from the factory in a clean, minimalist Helium White graphics and plastics package. However, if you want to personalize your machine, Bonnell produces two official alternative color accessory packages: Badlands Tan and Outrider Yellow. These custom plastic kits are sold separately and can be ordered directly through the Patriot Bikes parts department.

A: From the factory, the Bonnell 805 RX is delivered with an ultra-quiet, high-strength Belt Drive system. This belt setup provides smooth, immediate power delivery and operates almost silently, which is ideal for stealthy trail and enduro riding. For riders who plan to abuse the bike in deep mud, sand, or professional motocross tracks, an optional Heavy-Duty 520 Chain Conversion Kit can be purchased and installed to replace the belt with a traditional mechanical chain layout.

A: Battery range varies significantly depending on rider weight, track conditions, and how aggressively you manage the throttle. Under intense, wide-open motocross track racing conditions, a full charge will typically deliver 45 to 60 minutes of hard riding. For casual trail riding or tight technical enduro work, you can expect between 2 to 3.5 hours of run time.

The battery compartment is located directly underneath the seat and features a quick-release mechanical latching system. You can open the bay, lift out the depleted 3.9 kWh Core Battery, and drop a fresh, fully charged replacement pack into place in under 15 seconds without using any tools. This allows you to log continuous laps at the track all day long without waiting for a charger.

A: The Bonnell 805 RX features an integrated, secure Bluetooth module that syncs directly with the official Bonnell smartphone app (available for iPhone and Android). Once paired, the app unlocks access to 5 fully programmable ride modes. You can use simple digital sliders to adjust peak kilowatts, phase amps (which controls how hard the bike hits off the line), top speed limits, and throttle curve profiles. This means you can detune the bike into a mild, predictable trail cruiser for beginners, or crank all parameters to maximum for an explosive, professional-grade racing configuration.

A: While the Bonnell 805 RX features a direct-drive automatic transmission (meaning you never have to shift gears manually), the software allows you to map a handlebar lever to act as a virtual electronic clutch. When pulled, the controller momentarily cuts power delivery to the motor. When you snap the lever back out, the controller unleashes a massive, instantaneous pulse of phase amperage directly to the rear wheel. This perfectly mimics the action of "fanning the clutch" on a petrol dirt bike, allowing advanced riders to pop the front wheel over sudden logs, maintain momentum through tight corners, or execute explosive, high-traction race starts off the starting gate.

A: The Sirris A-Kit suspension package provides professional-grade adjustments similar to high-end petrol motocross bikes. The 43 mm inverted front forks and the rear coil shock feature external clickers that allow you to fine-tune both high-speed and low-speed compression damping, as well as rebound damping velocity. The rear shock linkage also allows for mechanical preload adjustment to set the proper rider sag. Patriot Bikes stocks alternative spring rates so we can tailor the internal coil stiffness to your exact naked weight and riding discipline before you collect your bike.

A: Yes, absolutely. At Patriot Bikes Wakefield, we offer flexible, competitive finance options to help break down the cost of your new e-moto into manageable monthly payments. We also accept part exchanges on your current dirt bike, electric bike, or scooter to help offset the initial purchase cost. Speak with one of our showroom team members or submit an online inquiry form, and we will put together a custom financing quote or provide a professional valuation for your trade-in vehicle.
