6,000W CYC X1 Pro Gen 4 Motor
At the heart of the Bonnell 775 MX is the CYC X1 Pro Gen 4 drive system.
This high-performance system produces up to:
- 6,000W peak power
- 280Nm torque at the crank
The integrated torque sensor allows the system to respond to rider input when using pedal assistance, while the full-twist throttle provides another way of accessing the bike’s performance.
This means the character of the 775 MX can change considerably depending on how it’s ridden and configured.
Full-Twist Throttle & Torque-Sensing Pedal Assist
The Bonnell 775 MX combines both pedal assistance and throttle control.
A Lekkie Pacemaker full-twist throttle is fitted, while the motor’s torque-sensing pedal-assist system responds to rider input through the pedals.
The Bonnell Ride Control App also allows compatible power and assistance settings to be adjusted, giving riders greater control over how the bike delivers its performance.
65V 1300Wh Removable Battery
Power comes from the CYC A65 Series 1300Wh battery.
The high-capacity 65V battery uses Samsung 50S cells and features an aluminium enclosure designed to help with heat dissipation.
An advanced dual-layer Battery Management System monitors important parameters including temperature, charging and current.
The battery is removable, allowing it to be taken out of the bike or swapped where required.
Under 4-Hour Charging
Despite its substantial 1300Wh capacity, Bonnell states that the battery can reach a full charge in under four hours using the supplied charger.
Actual charging times can vary depending on battery state, temperature and other conditions.
Bonnell 775 MX Range
Bonnell quotes an approximate riding range of:
- 20–60km
- or approximately 12–37 miles
Actual range will depend heavily on how the bike is ridden. Terrain, rider weight, gradients, temperature, tyre pressures, power mode, throttle use and pedal assistance can all affect the distance achievable from a charge.
Riding aggressively at maximum power will naturally produce considerably different results from riding predominantly with pedal assistance.
Approximately 34kg Total Weight
One of the most impressive aspects of the Bonnell 775 MX is its power-to-weight proposition.
The complete bike weighs approximately:
That relatively low weight is a major part of what separates the 775 MX from many heavier electric dirt bikes. Rather than relying purely on outright power, the Bonnell platform combines substantial electric performance with a chassis intended to remain agile, responsive and manageable on demanding terrain.
Bonnell 775 MX Top Speed
With its standard gearing, Bonnell quotes approximately:
- 37mph / 60km/h with the standard 24T rear sprocket.
Alternative sprockets can change the balance between acceleration, low-speed torque and maximum speed. Bonnell currently quotes approximately 40mph / 65km/h with a 22T sprocket, while larger sprockets sacrifice some maximum speed in favour of greater low-speed torque.
Actual speed will vary depending on gearing, rider, terrain, conditions and bike setup.
Suntour RUX 38 RC+ Dual-Crown Forks
The front suspension is proper downhill equipment.
The Suntour RUX 38 RC+ dual-crown fork provides a substantial 200mm of front suspension travel.
Features include:
- 38mm aluminium stanchions
- 200mm travel
- Adjustable rebound
- Adjustable compression
- 20x110mm Boost thru-axle
This gives the 775 MX the suspension capability required for demanding off-road terrain rather than relying on basic recreational e-bike components.
170mm Suntour Voro Coil Rear Suspension
At the rear is a Suntour Voro Coil shock, delivering 170mm of rear-wheel travel.
The suspension provides adjustment for compression and rebound, allowing the bike to be tuned according to rider preference and terrain.
Different spring rates are supplied according to frame size, while the chassis also provides Comfort and Sport shock mounting positions for further setup adjustment.
Magura MT5 Four-Piston Brakes
With up to 6,000W available, strong braking performance is essential.
The Bonnell 775 MX uses Magura MT5 four-piston hydraulic disc brakes. These are paired with large rotors:
The system provides the stopping performance expected from a serious downhill/off-road machine.
