STEALTH B-52 MRP Groove Duro Razorback MT5

B-52 stands at the forefront of the Stealth range, offering pilots a world-beating, all-terrain experience, ramped up by the 5.2kW electrical motor, which is paired with traditional pedal power.

A real-world synthesis of motocross capabilities and mountain bike dynamics, the B-52 holds a global reputation as one of the finest electric bicycles ever made, maintaining its pedigree through unsurpassed durability and bombproof construction.

The B-52 best suited to open, faster flowing trails where high speed is a priority.

The Duro Razorback offers excellent traction in loose and muddy terrain. The aggressive knobby tread pattern allows riders to attack the harshest trails at high speed with confidence and accuracy.

The Magura MT5 is designed to deliver outstanding performance in a wide range of conditions. The adjustable lever reach and ergonomic-matched 2-finger brake lever allows for as much brake power as you need.
The standard issue 8”, DNM USD-8 forks soak up unforgiving hits with ease. Compression and rebound adjustments can be made on the fly, allowing for precise tuning whether on the smoothest roads or the harshest landings.

Constructed from aircraft certified CrMo alloys, the monocoque frame displays exceptional torsional rigidity under the most extreme loading conditions. The battery fastening system allows for easy battery change overs for those who want to extend their ride.

The DC-1’s unique trip computer is the brains behind each model of the Stealth range. At a glance, the rider gains immediate status of speed, battery usage, and power output. The DC-1 monitors system temperatures and drive train performance in order to optimize power output and range.

Smooth and predictable engine like braking is activated by simply pressing and holding the regen button. Using the regen on long down hill runs reduces brake pad wear by converting kinetic energy to electricity, which is then fed back to the battery, extending the bike’s range.

The direct drive brushless DC hub motor has only one moving part guaranteeing low maintenance and running costs. Traction, reliability and efficiency is optimized through this advanced design producing virtually no sound emission.
