Built around everyday freedom
Easy to ride. Ready for more.
The Melody combines a very low step-through frame, upright comfort and intuitive power delivery with the practical accessories most riders would otherwise need to add later.
Long-range battery
The frame-integrated 48V 14.4Ah battery supplies 720Wh and uses Samsung 21700 lithium-ion cells.
Comfort-focused chassis
A 100mm suspension fork, swept handlebar, adjustable stem, ergonomic grips and sprung cruiser saddle reduce fatigue.
Confident stopping
Tektro hydraulic disc brakes with 180mm front and rear rotors provide smooth, controlled braking.
Equipped for the day
Full fenders, integrated lights and a MIK HD Click Go rear rack make the Melody useful from the first ride.
Clear cockpit information
The stem-integrated VeloFox color LCD keeps speed, assist, battery, range and ride data easy to see.
Power that adapts to you
Choose a natural feel or effortless cruise.

Torque mode responds to how firmly you pedal for a familiar bicycle-like sensation. Cadence mode supplies steady support whenever the cranks are turning. A thumb throttle and walk mode add control when starting, maneuvering or handling a loaded bike.

Questions riders ask
Magnum Melody FAQ
Is the Magnum Melody a Class 2 or Class 3 e-bike?
It is delivered in a Class 2 configuration with a 20 mph throttle. Its pedal-assist system can be configured for assistance up to 28 mph where Class 3 operation is legal. Always follow local trail and road rules.
Can I switch between torque and cadence sensing?
Yes. Torque mode varies support according to pedal pressure for a natural ride feel, while cadence mode provides steady assistance whenever you pedal.
Can the battery be removed for charging?
Yes. The 720Wh battery is integrated into the frame but removable, so it may be charged on or off the bike.
Will every rider get 55 miles of range?
No single range figure is guaranteed. Rider weight, cargo, terrain, temperature, tire pressure, wind, assist level, throttle use and riding speed all influence real-world range.
What rider size does the one-size frame accommodate?
Magnum lists a minimum rider height of 5 ft 1 in. The adjustable-angle stem and 32–39 in saddle-height range provide fit flexibility, but an in-person sizing check is recommended.
How much can the rear rack carry?
The included MIK HD Click Go rear rack is rated for up to 55 lb / 25 kg. The bike's maximum total load is 330 lb / 150 kg.
Does it arrive with lights, fenders and a charger?
Yes. The Melody includes integrated front and rear lighting, full-coverage fenders and a 54.6V 2A charger.
