Description
The e-Hard 11.11 is built on a rigid aluminum frame with modern geometry that provides stability at high speeds and confidence on technical sections. It’s designed for athletic riders who want a versatile e-bike for hills, forest trails, and lighter trail riding. The drivetrain is powered by a high-performance Avinox M2S motor, which offers smooth assistance, quick response, and plenty of power for steep climbs. The e-bike handles naturally, without jerking, and allows for a dynamic ride even on challenging terrain.
A New Standard of Quality for Aluminum Frames
The CRUSSIS MY27 sets a new standard for the quality of aluminum e-bike frames, where premium craftsmanship is the norm. Precisely ground welds, clean lines, and a look that’s almost carbon-fiber-like. The result is a combination of premium design, high strength, and durability that takes expectations for a modern e-bike to a whole new level. Because this is exactly what the standard for a high-quality e-bike should look like today.
SRAM DB8 Stealth – Front and Rear Hydraulic Disc Brakes
A high-performance hydraulic brake system designed for electric mountain bikes. The four-piston calipers provide reliable braking power and good control when riding on challenging terrain. Thanks to the Stealth design, the brake lines are elegantly integrated along the handlebars. The brakes use Maxima mineral oil and are easy to maintain. The ergonomic brake lever allows you to adjust its distance from the handlebars, so you can customize its position to suit your needs. Compatible with SRAM Post Mount adapters.
CRUSSIS e-Hard 11.11 (600 Wh) – a sport e-bike for challenging terrain
The CRUSSIS e-Hard 11.11 (600 Wh) is a sport mountain e-bike built for challenging off-road riding, long climbs, and technical trails. The aluminum frame, 29" wheels, FOX air fork, and powerful Avinox M2S motor create a package that combines strong assistance on climbs with confident handling on descents.
Avinox M2S Motor – Up to 150 Nm
At the heart of the e-bike is the Avinox M2S mid-drive motor, which delivers 130 Nm of torque and can briefly provide up to 150 Nm in Boost mode. The system’s maximum power output reaches up to 1,500 W, so the e-bike can handle even steep climbs and technically challenging sections. Control is provided by the 2-inch Avinox DPC100 OLED touchscreen and wireless handlebar controls.
Integrated Avinox 600 Wh Battery
Power is supplied by an integrated Avinox battery with a capacity of 600 Wh, which maintains the frame’s clean look and contributes to the bike’s low center of gravity. A 12A charger is available for quick recharging. Range varies significantly depending on riding style, terrain, route profile, and other conditions; the manufacturer estimates a range of up to 100–250 km.
FOX AWL 34 with 130 mm of travel
The front features a FOX AWL 34 29" BOOST air fork with 130 mm of travel and a 44 mm offset. It provides the necessary support during more aggressive riding while also responding sensitively to roots, rocks, and other uneven terrain. The BOOST design contributes to the front end’s stiffness and confident tracking.
SRAM 70 T-Type Eagle 1×12
The SRAM 70 T-Type Eagle 1×12 provides a wide gear range. The SRAM XS-1270 Eagle T-Type cassette, with a 10–52-tooth range, offers plenty of gears for steep climbs and faster riding on flat sections. Precise shifting is complemented by the SRAM T-Type Eagle 34-tooth chainring.
29" wheels and Maxxis Rekon tires
The large 29" wheels feature double-walled 30mm CRUSSIS rims and solid BOOST hubs—15×110 mm in the front and 12×148 mm in the rear. The bike is equipped with MAXXIS Rekon 29 × 2.60 tires, which feature a deep tread pattern and provide good traction on gravel, forest roads, and technical trails.
SRAM DB8 Stealth Hydraulic Brakes
SRAM DB8 Stealth hydraulic disc brakes ensure safe deceleration. Large 200 mm discs at the front and rear provide the necessary braking power even during longer descents and intense off-road use.
X-Fusion Manic dropper post
A practical feature for trail riding is the X-Fusion Manic dropper post, which allows you to adjust the saddle height while riding. On descents, this lets you lower your center of gravity and gain more room to actively control the bike.
The CRUSSIS e-Hard 11.11 (600 Wh) is an e-bike designed for riders who want significant motor assistance, high-quality suspension, and components ready for more challenging terrain. The combination of the Avinox M2S drive, a 600 Wh integrated battery, a 130 mm FOX fork, a dropper seatpost, and 29" wheels gives the bike a sporty character and a wide range of uses, from brisk trail rides to more demanding mountain routes.
