The Bonnell 775 MX v2 is built for riders who want the pedal layout of an electric mountain bike with the acceleration and structural confidence of a lightweight dirt bike. At approximately 75 pounds, it is substantially heavier than a conventional e-MTB, but that added mass supports a high-output platform designed for steep climbs, rugged descents, and aggressive trail riding.
With a claimed 6,000W peak output and 280 Nm of torque, the 775 MX v2 isn’t meant to feel like a mild pedal-assist bicycle. Its moto-style twist throttle, high-discharge battery, long-travel fork, and powerful hydraulic brakes place it in a specialized hybrid category between a high-performance e-MTB and a compact electric dirt bike. You can compare them at Ronster Bikes.
6,000W Motor and 280 Nm of Torque
The Bonnell 775 MX v2 uses a CYC X1 Pro Gen 4 motor rated for up to 6,000W of peak power and 280 Nm of torque. This output gives the bike the force needed to attack steep embankments, loose climbs, and deep sand where lower-powered electric mountain bikes may lose momentum.
Acceleration is controlled through a moto-style twist throttle rather than relying solely on conventional pedal assistance. The result is a direct, dirt-bike-like response that requires careful throttle control on technical terrain, loose surfaces, and narrow trails.
65V 1300Wh Samsung 50s Battery System
Power comes from a 65V, 1300Wh battery pack built with Samsung 50s cells. The configuration is designed for a high discharge rate, allowing the motor to sustain strong acceleration rather than delivering only a brief peak burst.
Actual range will vary according to rider weight, terrain, throttle use, elevation changes, temperature, tire pressure, and riding mode. Aggressive hill climbing and repeated full-power acceleration will consume energy much faster than steady trail cruising, so riders should plan battery use around the intended route rather than relying on a single theoretical range figure.
Over-40-MPH Trail Platform
The Bonnell 775 MX v2 is described as capable of exceeding 40 mph, or approximately 64 km/h. At that speed, it demands motorcycle-level attention to braking distance, surface conditions, protective equipment, and trail access rules.
Its 75-pound weight contributes to stability at speed, but it also affects low-speed maneuverability. Riders should expect more momentum when entering turns, braking before obstacles, or correcting a line on loose ground. The bike is better suited to open, demanding terrain than to slow, highly technical singletrack requiring frequent hops and rapid direction changes.
Downhill-Ready Suspension and Braking Hardware
A 200mm SR Suntour dual-crown front fork provides substantial travel for absorbing downhill impacts, rough landings, braking bumps, and uneven rock sections. The long-travel setup is aligned with the bike’s high-speed, downhill-focused character rather than lightweight cross-country riding.
Stopping power comes from Magura MT5 four-piston hydraulic brakes paired with oversized 220mm floating rotors. This combination is intended to manage the Bonnell’s speed and mass during repeated hard braking, long descents, and high-load trail approaches.
Riders should still set brake reach, pad condition, rotor alignment, and suspension settings to their weight and terrain. Powerful hardware cannot replace proper braking technique or adequate reaction distance.

What the v2 Factory Upgrades Fix
The 775 MX v2 addresses several structural and durability concerns associated with the earlier v1 configuration. The changes focus on wheel protection, spoke strength, rim reliability, pedal clearance, rear suspension, and drivetrain adjustment.
The result is a platform more deliberately matched to its motor output. These are not cosmetic revisions: each upgrade targets a component exposed to high torque, heavy landings, repeated impacts, or the additional mass of the bike.
Rear Wheel Protection with a Factory Tannus Insert
The v2 replaces the standard tube setup with a factory-installed Tannus insert. This adds protection against impacts and reduces the risk of a rear-wheel failure when the bike is ridden aggressively over rocks, ledges, and rough landings.
A tire insert does not make the wheel immune to damage. Correct tire pressure, rim inspection, and appropriate line selection remain important, particularly because the bike’s weight and torque place substantial loads on the rear wheel.
Thicker 13-Gauge Spokes and a Welded Rim
Bonnell equips the v2 with thicker 13-gauge spokes instead of the standard-gauge spokes used on the v1. The stronger spoke specification is intended to improve wheel resilience under high torque and impact loads.
The rim also changes from a standard pinned seam to a welded construction. This supports a more dependable tubeless seal and reduces one potential source of air loss during demanding trail use. Riders should still check spoke tension, rim straightness, and seal integrity as part of routine maintenance.
Shorter Cranks for Improved Pedal Clearance
The v2 uses shorter cranks to reduce pedal strikes. This is particularly relevant on a heavy, high-torque bike ridden through rock gardens, rutted climbs, and uneven singletrack, where long cranks can contact obstacles or the ground during technical pedal rotations.
Shorter cranks can improve clearance, but riders must still choose lines carefully and remain aware of the bike’s larger frame and moto-style weight distribution.
Heavy-Duty Rear Shock and Integrated Chain Adjuster
The rear suspension is upgraded from the earlier entry-level air or coil configuration to a heavy-duty coil rear shock. This change is intended to provide more dependable support under the bike’s weight, high-speed landings, and repeated downhill impacts.
The redesigned integrated chain adjuster replaces the v1’s fixed positioning. This gives the drivetrain more practical tension adjustment and can simplify setup and maintenance as the chain and components wear.
Extreme Climbing Ability on Loose Terrain
The 280 Nm torque figure is the Bonnell’s defining trail advantage. It gives the 775 MX v2 the ability to maintain momentum on steep embankments, deep sand, and loose climbs that can overwhelm conventional e-MTB power systems.
This output also requires restraint. Too much throttle can break rear-wheel traction, unload the front end, or make a technical climb harder to control. Riders will get the most from the motor by modulating throttle input, choosing a balanced body position, and matching power delivery to the available grip.
Pedals, Trail Access, and Legal Classification
The 775 MX v2 retains functional pedals, which may provide access to certain trails or riding areas that exclude full electric dirt bikes. However, the presence of pedals does not automatically make a high-powered e-bike legal everywhere.
Trail access, road classification, speed limits, power thresholds, throttle rules, registration, insurance, and equipment requirements vary by jurisdiction and land manager. Riders should verify the applicable rules before using the bike on public roads, bike paths, or managed trails.
Handling a 75-Pound Hybrid E-Bike
At approximately 75 pounds, the Bonnell does not handle like a lightweight 50-pound electric mountain bike. It can be more difficult to bunny-hop, lift over obstacles, flick through tight turns, or recover quickly from a poor line choice.
That weight becomes an advantage on fast descents and rough terrain, where it contributes to stability and a planted feel. The trade-off is a more physical riding style: riders must plan turns earlier, brake decisively, and use body positioning to manage momentum.
Who Should Buy the Bonnell 775 MX v2?
The Bonnell 775 MX v2 suits experienced riders who specifically want a high-output hybrid rather than a nimble cross-country e-MTB. It is a strong match for riders prioritizing steep climbing, high-speed trail stability, downhill hardware, and structural upgrades over portability and bicycle-like agility.
It is less suitable for riders who want a lightweight bike for carrying upstairs, tight woodland singletrack, long-distance pedal touring, or low-speed technical riding that demands frequent manual lifts and quick direction changes.
Final Buyer’s Verdict
The Bonnell 775 MX v2 is a specialized, high-adrenaline trail machine. Its CYC X1 Pro Gen 4 motor, 65V 1300Wh battery, 200mm dual-crown fork, Magura four-piston brakes, factory Tannus insert, reinforced spokes, welded rim, shorter cranks, heavy-duty coil shock, and integrated chain adjuster create a far more robust package than a conventional e-MTB.
It lacks the nimbleness of a traditional mountain bike, and its 75-pound weight demands deliberate handling. But for riders seeking a powerful, dirt-bike-style hybrid with pedals and substantial v2 durability improvements, the Bonnell 775 MX v2 is a compelling apex e-bike platform.
