TOOJUN 48V 1000W 28-inch E-Bike Conversion Kit

Electric bikes have revolutionized urban commuting and off-road adventures, but investing in a brand-new e-bike can feel like an unnecessary expense—especially if you already love your trusty mountain bike. For cyclists seeking to blend familiarity with electric convenience, the TOOJUN 48V 1000W Rear Hub Motor Conversion Kit (28-inch variant) is a standout solution. Designed for mountain bikes and regular bicycles alike, this kit transforms your existing frame into a capable e-bike, ideal for daily commutes, weekend trail rides, or simply easing the strain of steep hills. It’s a smart, cost-effective way to retain the bike you know while adding the power you need.

Core Performance: Power Without Compromise

At the heart of this kit lies a 48V 1000W brushless, gearless rear hub motor—a choice that prioritizes efficiency, silence, and low maintenance. Brushless motors are superior to their brushed counterparts: they operate without friction (no carbon brushes to wear out), deliver smoother power, and run almost silently. The gearless design eliminates the whirring noise common in geared motors, making for a more immersive ride—whether you’re gliding through city streets or navigating quiet woodland trails.

For riders who face hills regularly, the 1000W output is a game-changer. Steep inclines that once left you breathless become manageable; the motor’s torque kicks in seamlessly, letting you climb without straining. “I live in a hilly area, and this motor turns my morning commute from a slog into a breeze,” says one user from Bristol. “I can maintain 15mph up hills that used to slow me to a walk.” The gearless design also means fewer moving parts to maintain—no gears to lubricate or replace, just reliable performance ride after ride.

It’s worth noting that the battery is sold separately (we recommend pairing it with a high-quality 48V lithium-ion battery for optimal range), but the motor’s efficiency ensures you get the most out of every charge.

Thoughtful Components: Safety, Convenience, and Control

TOOJUN hasn’t cut corners on the accessories—each component is designed with rider experience in mind:

LCD7 Display

The clear, backlit LCD screen is a highlight. It shows battery percentage, current speed, total distance traveled, and single-trip distance—all at a glance. Unlike clunky displays that require squinting or frequent adjustments, this one is intuitive. “I love that I can see exactly how much battery I have left,” says Sarah, a commuter from Manchester. “No more guessing if I’ll make it to the next charge point.” The display mounts easily to your handlebars and stays secure even on bumpy trails.

Thumb Throttle

The ergonomic thumb throttle attaches to your existing grip—no need to replace or reposition anything. A gentle push delivers instant power, making it easy to accelerate from a stop or boost up hills. “I was worried the throttle would feel awkward, but it’s so natural,” says Mark, a trail rider from Leeds. “I can switch between throttle-only and pedal assist without breaking my flow.”

Power-Cut-Off Brake Levers

Safety is non-negotiable, and these brake levers deliver. As soon as you squeeze the lever, the controller cuts power to the motor instantly. This prevents accidental acceleration while braking—a crucial feature for urban riders navigating traffic or trail users handling tight turns. “The brake response is so quick,” says Tom, a hybrid bike owner from Birmingham. “When I hit a red light, the power cuts immediately, which makes me feel safer in busy streets.”

Durability: Built to Last

A conversion kit is only as good as its ability to withstand repeated use—and this one excels:

Double-Wall Aluminum Alloy Rim: The rim is lightweight yet incredibly strong. It resists dents and scratches from curbs, rocks, or potholes, making it ideal for off-road trails and daily commutes.
High-Carbon Steel Spokes: Thicker and more rigid than standard spokes, they provide stability even when carrying heavy loads (the kit supports up to 220 lbs). “I carry a backpack full of work gear every day, and the wheel never wobbles,” says Sarah.
Compatible Frame Integration: The motor wheel slots seamlessly into most mountain bike frames—no modification required. The high-carbon steel construction of the wheel (compatible with your existing bike’s frame) is built to handle repeated use, from city potholes to trail rocks.

“I’ve had this kit for six months, and it’s still like new,” says Mark, who rides weekly in the Peak District. “The rim hasn’t buckled, the spokes are still tight, and the motor runs just as smoothly as day one.”

Installation: Easy for DIYers of All Skill Levels

One of the biggest fears about e-bike conversions is complicated installation—but this kit is designed for accessibility. The package includes:

A detailed manual with step-by-step instructions (and diagrams)
All basic hardware (cable ties, mounting brackets, screws)
The motor wheel, controller, thumb throttle, brake levers, and pedal assist sensor

Most riders complete the conversion in 1–2 hours. “I’m not handy at all, but I had my bike up and running in 90 minutes,” says Tom. “The instructions were clear, and everything fit perfectly. The pedal assist sensor was just a few zip ties to my crank—super easy.”

Another user adds: “The motor wheel slotted right into my frame. I didn’t need any special tools—just a wrench and a screwdriver.” For cyclists who want to avoid professional installation fees, this kit is a winner.

Real-World User Feedback

The best way to judge a product is through real riders—and this kit has earned rave reviews:

Commuters: “I use it to get to work every day, and it’s cut my commute time by 20 minutes,” says Sarah. “The LCD display lets me track my speed and battery, and the brake levers are so responsive. I feel safer in traffic now.”
Trail Riders: “I’ve taken this on muddy trails, rocky sections, and steep climbs—all without issues,” says Mark. “The motor’s power is great for off-road, and the silent operation means I can still hear the birds while I ride.”
Casual Riders: “I converted my old hybrid bike, and it’s perfect for weekend rides,” says Emma from Cardiff. “The thumb throttle is comfortable, the pedal assist makes hills easy, and the display keeps me informed. I wish I’d done this sooner!”

Who Is This Kit For?

This kit is ideal for:

Commuters who want to speed up their daily ride without buying a new e-bike.
Trail riders who want to add power to their mountain bike for steep climbs.
Casual cyclists who want to ease the strain of long rides or hills.
Anyone who loves their existing bike but wants electric assistance.

It’s compatible with most mountain bikes and regular bicycles (28-inch wheels)—just check your frame’s dropout spacing (standard 135mm for rear hubs) to ensure a fit.
