STEALTH B-52 Groove Duro Razorback MT7

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 Magura MT7 offers a 4 piston forged caliper, with a unique 4 pad monoblock configuration. This upgrade is better suited to more extreme riding styles. The aluminium 2-finger brake lever with tool-less reach and bite point adjustment, provides precise braking control with ergonomic comfort.

The American made MRP Groove 200 fork is an air/oil/coil inverted design which ensures a supple ride over harsh terrain. This 200mm suspension upgrade offers adjustable preload, compression, rebound and bottom-out adjustments.

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 drivetrain performance in order to optimize power output and range.

Smooth and predictable enginelike 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.
