Australian company Stealth Electric Bikes, high-performance electric vehicles leader, unveils its new off-road range homologated 2022.
After signing strategic partnerships earlier this year with C-Creative of San Marino for the design and development of its new vehicle platforms and also Vmoto Soco Italia for the synergic development of the sales and after-sales network in Italy, Stealth’s new products are set to change the way to think about light weight personal mobility and off-road recreation.
Technical improvements have been made in several areas, from CrMo monocoque chassis, to the high torque direct drive hub motors.
The frame and swingarm on the H-52, F-37 and B-52 models have been completely redesigned with updated geometries and improved ergonomics to improve high speed stability with provide a more comfortable cockpit for the rider.
Handling over rough terrain has also seen a significant improvement with updated suspension and the wheel diameters increased from 24” to 27.5” across the board.
The new range is equipped with motocross derived brakes and 250mm rotors ensuring shorter stopping distances, more precise lever control and no chance of brake fade on the gnarly downhill trails
The high torque, direct drive hub motors used on the H-52’s, F-37’s B-52’s have all undergone a number of optimisations with improvements in cooling provided by a combination of circumferential heat transfer fins and ferro-magnetic cooling technology.
Throttle mapping and power delivery have also been improved to provide operators with more control and a much smoother ride.
On both of the H-52 and B-52 variants, the most powerful in the range, NCM battery technology has been improved to increase energy density and overall capacity and range by up to 25%.
The latest generation Stealth B-52s, (available in Q1 of 2022) will no longer use the traditional Suntour 9 speed Vbox and will be replaced by Stealth’s proprietary Hex Box transmission. Tougher than ever, the Hex Box’s oil bath transmission provides new B-52 pilots with 6 pedals speeds, all controlled by a new electromechanical gear shifting mechanism. Doing away with the old fashioned cable operated gear shifter simplifies the system and has it’s own in-built in power source which will allow pilots to continue to shift gears even after the main traction battery has been depleted.
The off-road range currently consists of the following versions: P-7, P-7R, F-37 and H-52 which wil all be available from the beginning of December from Stealth dealers across the world and will be followed up by the B-52 which will come online early in 2022.
As an extension to the family, Stealth will be introducing L1eB homologated variants known as the H-52S, B-52S and F-37S which fall into the same registration category as most 50cc motorcycles/scooters across Australia, Europe and the UK. The new “S” models will benefit from all of the technical improvements made to the off road models with the addition of lights, indicators, mirrors, mudguards and license plate in order to meet the registration requirements of the vehicle.
The homologated variants will be available at Stealth dealers from March 2022
The new homologated version of the Stealth Electric Bikes range will be displayed at EICMA in Milan, Hall 22 stand Q20.
