Speed & Performance
Pure, electromagnetic thrust
The Stealth B-52’s latest electric hub motor technology takes your mission to the next level with improved torque and quicker acceleration while still maintaining its renowned, low maintenance, low profile signature.
This year we increased power by 20% and reduced the motor weight by over 20% to enhance handling and deliver a smooth, controllable punch when it’s time to twist the throttle and cover serious ground fast.
Supported by the B-52’s proven 9-speed sequential Vboxx, you can transmit short bursts of high intensity pedal strokes in parallel with the electric power train to literally double the torque while accelerating hard off the start line or roosting out of corners.
Electrical & Power
Leading the charge
Stealth’s proprietary DC-1 display collects real-time data and vital stats such as speed, battery consumption, range estimation and efficiency to give you accurate, intuitive systems updates at a glance.
In a world where efficiency and reliability mean everything, Stealth’s solid state, digital inverter technology has absolutely no moving parts, eliminating the possibility of wear and tear and reducing periodic maintenance intervals.
In Economy mode, without pedaling, the B-52’s 2.0kWh battery will deliver a range of up to 100km (60 miles) on flat terrain, while a full throttle blast in Competition mode will easily shred a 40km (25 mile) trail when approaching warp speed.
With a 3 hour recharge time, all Stealth customers are given the convenience of plugging in to any 110/240V household outlet to stock up on those vital electrons.
Suspension & Braking
Jump, brake and turn with confidence
Tuned and spec’d by the Stealth team, the B-52’s long travel, heavy duty suspension package gives pilots the confidence to take on the toughest trails without compromising comfort. Air adjustability provides a convenient platform for riders to fine-tune their suspension to suit a wide range of terrain and riding style in just a few minutes.
When slowing down or coasting, pilots have quick access to Regen braking which recovers kinetic energy, feeding it back into the battery pack, further enhancing range and ride time.
If the next obstacle is approaching faster than expected, precise stopping control is supported by Magura’s 4 piston hydraulic brakes clamping down on 203mm rotors to provide German braking accuracy with no more than 2 fingers on the levers.
Frame & Dimensions
Adjustability for a wide range of riders
With over 10 years of intensive R&D, the Stealth B-52’s proven monocoque chassis design has taken thousands of devoted customers soaring to new heights. Built using only the best quality, certified aircraft grade CroMoly alloys the B-52’s latest evolution is as light weight and as tough ever before.
Dimensionally, the Stealth B-52 comes in a large frame size with enough adjustability to suit most riders ranging from 162cm (5’4”) up to 193cm (6’4”) and a maximum rider weight of 120kg.
The B-52’s footprint shares a similar profile to that of a large frame downhill mountain bike meaning that you can still load it on to your heavy-duty bike rack, or easily transport it in an elevator or small van
