Description

One Bike. Every Terrain. 21 Ways to Ride It.

This new multi-function electric mountain bike combines a clean integrated wheel design with the full versatility of a 21-speed Shimano gear system and a powerful lithium battery — giving you a single bike that handles mountain trails, urban commutes, fitness rides, and long-distance adventures with equal confidence. Whether you’re climbing steep inclines or cruising flat city roads, 21 gear levels and 5 pedal assist modes mean you always have the perfect setting for the moment.

Motor & Performance

• 500W high-speed brushless motor delivering up to 50Nm of torque for strong climbing ability and smooth, confident acceleration
• Top speed of up to 20 MPH (32 km/h) — suitable for trails, bike lanes, and urban roads
• 5 levels of pedal assist (PAS) allowing riders to fine-tune motor assistance from gentle boost to full power support
• Throttle mode for full electric power without pedalling — ideal for headwinds, steep inclines, and tired legs
• Cruise control function maintaining a consistent speed without holding the throttle — ideal for long-distance flat riding

21-Speed Variable Gear System

• 21-speed Shimano derailleur system — the standout feature of this bike, offering a huge range of gear ratios suited to every riding scenario
• Lower gears make steep uphill climbs effortless — combined with PAS motor assist, even the most challenging gradients become manageable
• Higher gears allow fast, efficient riding on flat roads and downhill sections
• Smooth, precise shifting between all 21 speeds for a seamless, natural riding experience across all terrain types
• Works independently of the electric motor — giving you full manual cycling capability when you want exercise without electric assist

Integrated Wheel Design

• Integrated wheel construction — spokes, rim, and hub combined into a clean, unified design for a sleek, modern aesthetic and improved structural rigidity
• Integrated design reduces the risk of spoke damage on rough mountain terrain
• Clean, uncluttered visual profile that distinguishes this bike from standard wire-spoke mountain e-bikes
• Combined with integrated down-tube lithium battery for a streamlined, cohesive frame appearance

Battery & Range

• 48V removable lithium-ion battery integrated cleanly into the down tube for balanced weight distribution and a tidy frame profile
• Range of 22–25 miles in pure electric mode and 44–50 miles with pedal assist on a single charge
• Full charge in approximately 4–6 hours on a standard household outlet
• Battery features power-off, over-current, and overcharge protection for safe, reliable daily operation
• Zero emissions — no fuel costs, no oil changes, significantly lower running costs than a car or petrol motorcycle

Suspension, Brakes & Build

• Front suspension fork with lockout capability — engage suspension for rough off-road terrain, lock it out for faster, more efficient road riding
• Dual mechanical disc brakes with instant power-cut system — motor cuts automatically when brakes are applied for added safety
• Lightweight aluminium alloy frame — strong, corrosion-resistant, and responsive across varied terrain
• 26-inch mountain tyres with knobby tread for confident grip on dirt, gravel, mud, and mixed surfaces

Multi-Function Features

• Integrated LCD display showing speed, battery level, PAS mode, trip distance, and odometer at a glance
• LED headlight for safe visibility during early morning and evening rides
• Rear cargo rack compatible for commuting utility
• 85% pre-assembled out of the box with installation video support and one-year warranty on motor, battery, and charger
• Max load capacity of up to 265 lbs (120 kg) for a wide range of adult riders

Ideal For ✔ Mountain trail and off-road riding ✔ Long-distance leisure and fitness cycling ✔ Urban commuting with occasional off-road capability ✔ Riders wanting maximum gear flexibility across varied terrain ✔ Buyers seeking a multi-function e-bike that handles everything from mountain paths to city streets
