Rear Hub Motor 48V-52V 1500W

When it comes to converting a standard bicycle into a high-performance electric machine, nothing cuts through the noise like raw, reliable power. The Rear Hub Motor 48V-52V 1500W is exactly that — a precision-engineered, full-conversion kit designed for builders who refuse to settle for mediocre output. Whether you’re tackling steep gradients, hauling load across uneven terrain, or simply demanding more from your build than a budget kit can deliver, the Rear Hub Motor 48V-52V 1500W gives you the hardware to make it happen. This is a complete drivetrain solution, not a partial upgrade — and every component in the box has been selected to work as a unified, high-output system.

The 1500W rear hub motor sits at the centre of this kit, and it defines everything about how this build performs. Brushless motor technology eliminates the friction, heat, and wear associated with traditional brushed designs. There are no physical contact points between rotor and stator — power transfer is magnetic, clean, and continuous. The result is a motor that runs whisper-quiet, generates minimal heat under sustained load, and demands virtually zero routine maintenance. Spin it hard for an hour on a demanding trail and it comes back for more. That’s the benchmark brushless technology sets, and this motor meets it without compromise.

48V and 52V — Dual Voltage, Maximum Flexibility

Voltage compatibility is one of the most important considerations in any e-bike conversion build, and the Rear Hub Motor 48V-52V 1500W handles both without modification. At 48V, you get a well-rounded performance profile — strong torque delivery, reliable acceleration, and broad compatibility with the most widely available lithium battery packs on the market. Move up to 52V and the character of the build shifts noticeably. Peak power increases, acceleration sharpens, and the motor operates with greater electrical efficiency — higher voltage means lower current draw at equivalent power output, which translates directly to reduced heat in both the motor windings and the controller circuitry. Less heat means longer component life, more consistent performance over time, and a system that holds its output curve even during extended hard use.

This dual compatibility also makes the Rear Hub Motor 48V-52V 1500W an excellent choice for staged builds. Start with a 48V battery pack today, upgrade to a higher-capacity 52V system as your build evolves — the motor accommodates both without any changes to the core drivetrain.

The 36V-52V 35A Controller — Precision Power Management

Every 1500w ebike kit lives or dies by the quality of its controller, and this one ships with a 36V-52V 35A unit that’s tuned specifically for high-output hub motor applications. Running at 35 amps continuous, the controller manages motor phase switching with precision — power delivery is smooth and progressive across the entire throttle range, with no jerky step-up, no hesitation at low speed, and no power drop-off at the top end. Throttle response feels natural and linear, which matters enormously when you’re navigating technical terrain or managing speed through variable conditions.

The controller’s wide voltage range — 36V through to 52V — gives this 1500w ebike kit exceptional battery compatibility. Whether you’re running a standard 48V downtube pack or a high-density 52V triangle battery, the controller adapts without modification. For builders looking to push beyond the included controller toward higher-amperage configurations, our 48V-72V 45A eBike Controller is a direct upgrade path that pairs cleanly with this motor platform. And for those exploring a lower-output starting point before stepping up to the 1500W tier, the Rear Hub Motor 36V-48V 500W provides useful context on where this kit sits in the wider performance range.

Complete Kit — No Missing Parts, No Guesswork

The Rear Hub Motor 48V-52V 1500W ships as a fully specified, ready-to-install conversion package. Every component needed for a complete rear electric motor for bike installation is included in the box — there’s no separate sourcing required, no compatibility hunting, and no last-minute parts orders delaying your build. Here’s exactly what’s included:

• 1500W rear wheel MTX brushless hub motor
• Front wheel MTX
• Motor controller 36V–52V 35A
• UKC1+ display
• Twist throttle — Surron style
• Torque arms — 2 sets
• Wiring harness & connectors
• Brake cut-off levers

This is a complete rear electric motor for bike conversion — rear motor, front wheel, controller, display, throttle, torque arms, wiring, and braking interface all included. Nothing is an optional extra. Nothing is left to chance.

MTX Wheel Construction — Built for High-Power Applications

Both the rear hub motor wheel and the included front wheel are built on the MTX rim platform. MTX is a double-walled aluminium rim construction that’s become the standard choice for high-power hub motor builds precisely because it handles the elevated stress loads that a 1500W rear electric motor for bike generates far better than conventional single-wall alternatives. Under high torque, standard rims flex, lose true, and eventually fail. MTX rims don’t. The double-wall structure maintains lateral stiffness, keeps spoke tension consistent over time, and handles repeated hard acceleration without deformation. This is the kind of component-level engineering detail that separates a properly specified kit from a cheap assembly.

UKC1+ Display and Surron-Style Throttle

The UKC1+ display is a clean, functional rider interface that puts critical data in front of you in real time — current speed, battery level, assist mode selection, trip distance, and odometer. The screen is clear and legible, the interface is intuitive, and the unit integrates seamlessly with the controller included in this 1500W rear hub motor kit. No configuration headaches, no compatibility issues — plug in, power up, ride.

The Surron-style twist throttle is a full-grip unit that delivers precise, progressive throttle control from rest to full power. Grip feel is solid, the mechanism is smooth, and the progressive response curve pairs well with the 35A controller’s power delivery characteristics. This is not a cheap plastic thumb throttle bolted on as an afterthought — it’s a proper full-grip unit that gives you genuine control over 1500W of output.

Torque Arms and Brake Cut-Off Integration

Two sets of torque arms are included as standard — and this is not a detail to overlook. At 1500W, the rotational force generated by the hub motor during hard acceleration creates significant stress on your dropout. Without properly installed torque arms, that stress causes axle rotation within the dropout, which damages the frame and can lead to catastrophic failure under load. Two sets means you have the hardware for both front and rear installations, and the quality of the included units is appropriate for the power levels this 52V 1500W motor operates at.

Brake cut-off levers are also included and integrate directly with the controller. The moment you apply brake pressure, motor power cuts instantly — a critical safety feature that also protects the motor from the stress of braking against active drive torque. Clean integration, immediate response, properly engineered.

Why the 52V 1500W Motor Stands Apart

At this power level, the 52V 1500W motor occupies a genuinely unique position in the conversion kit market. It’s powerful enough to handle virtually any terrain a bicycle can physically traverse — steep climbs, loaded cargo builds, high-speed trail riding — while remaining compact enough to install on a standard bicycle frame without structural modification. Mid-drive systems at this power level demand frame-specific mounting and significantly more complex installation. The hub motor format keeps things simple: lace the wheel, bolt the axle, wire the controller, and ride.

The 52V 1500W motor also runs significantly cooler than lower-voltage equivalents producing the same output. Higher voltage, lower current — the physics are straightforward, and the thermal benefits are real. A cooler motor is a more reliable motor, and reliability is what separates a daily rider from a garage project that spends more time being fixed than ridden.
