MRM EcoPit BOMB 19"/16" Electric Pit Bike

MRM EcoPit BOMB is a powerful electric pit bike built for more experienced riders who want a combination of low weight, strong pulling power and a genuine off-road feel. This is no ordinary children's electric motorbike – the EcoPit BOMB is a capable vehicle with serious power, a quality chassis and components that are up to the demands of faster off-road riding.

The EcoPit BOMB is ideal for riders who have outgrown smaller electric motorbikes and want something more powerful, more stable and more technically advanced. Its dimensions, 850 mm seat height and 19/16 wheels give the bike a noticeably more planted feel and excellent ability over rough terrain.

Powerful QS120 70H electric drive
At the heart of the bike is a powerful QS120 70H BLDC inner-rotor electric motor, known for its strong torque, high rotational speeds and very good reliability. This motor delivers instant power without gear changes, without delay and without the complex maintenance associated with combustion engines.

The motor is mounted centrally in the frame, helping to improve weight distribution and give the bike more natural off-road handling. This makes the EcoPit BOMB feel more assured through corners, on climbs and over uneven ground.

Power that commands respect
The EcoPit BOMB is built for riders who want truly strong electric pulling power. The motor delivers high torque and a quick throttle response, sending the bike surging forwards instantly. At the same time, the electric drive is quiet, smooth and easy to control.

• Motor: QS120 70H BLDC inner rotor
• Rated power: 3000 W
• Peak power: up to 11 kW
• System voltage: 72 V
• Torque: up to 120 Nm
• Top speed: over 80 km/h depending on settings, rider and conditions

FarDriver 72450 – precise power control
Power delivery is managed by the high-performance FarDriver 72450 controller. It provides a very smooth throttle response and more precise control over the power. The result is a bike that is easy to manage at lower speeds yet delivers a sharp burst of power when needed.

72 V / 36 Ah battery
Energy comes from a powerful 72 V battery with a capacity of 36 Ah, designed for a high-performance electric drive. The higher voltage gives the bike stronger pulling power, more consistent performance and plenty in reserve for brisk off-road riding.

A proper pit bike chassis
The EcoPit BOMB is built around a strong steel frame with a lightweight aluminium swingarm. This combination provides a good balance of strength, durability and weight, making the bike ready for regular off-road use, jumps, climbs and faster sections.

• Frame: steel
• Rear swingarm: aluminium
• Top yoke / fork mounting: forged steel
• Handlebars: aluminium, approx. 31" wide, 22 mm diameter
• Chain: heavy-duty 428H

Suspension ready for off-road riding
The front of the bike uses an upside-down fork with approximately 170 mm of travel. Rear suspension is provided by a monoshock with adjustable rebound damping and preload. This allows the bike to be better tailored to the rider's weight, riding style and terrain.

• Front suspension: upside-down fork, 48 mm, approx. 170 mm travel
• Rear suspension: monoshock
• Rear shock adjustment: rebound damping and preload
• Rear shock stroke: approx. 57.5 mm

Motorcycle-specification hydraulic brakes
The braking system is one of this model's key strengths. The EcoPit BOMB uses full hydraulic disc brakes, master cylinders with fluid sight glasses, braided brake hoses and durable discs. The brakes offer strong stopping power that is also easy to modulate.

• Front brake: hydraulic disc, 2-piston caliper
• Front disc: 220 mm, 4 mm wide
• Rear brake: hydraulic disc, 1-piston caliper
• Rear disc: 190 mm, 4 mm wide
• Brake hoses: braided

19/16 wheels – confidence off road
The combination of a 19" front wheel and a 16" rear wheel is ideal for riders who want better ability over rough terrain, stability and a more assured ride over uneven ground. The larger front wheel helps tackle obstacles, while the 16" rear wheel provides good traction and control.

Looks to match the performance
The EcoPit BOMB has sharp motocross styling, durable plastics and aggressive proportions. It looks and feels like a more grown-up pit bike while retaining the benefits of a lightweight electric design.

Who is the EcoPit BOMB suitable for?
We recommend this model for more experienced riders who already have experience with smaller pit bikes or electric motorbikes. With its high power, speed and strong motor, it is not suitable for complete beginners without supervision.

• for more experienced young riders
• for teenage and adult riders of small to medium stature
• for off-road riding, trails, meadows, forest tracks and private tracks
• for riders who want a powerful electric alternative to combustion-engined pit bikes
