For many UK commuters and casual cyclists, the appeal of electric bikes (e-bikes) lies in their ability to make daily travel faster, less strenuous, and more enjoyable—without the cost of buying a brand-new model. Converting an existing bicycle to electric is a smart solution: it preserves the familiarity of your trusted ride, saves money, and reduces waste. The TOOJUN Electric Bicycle Conversion Kit (1000W-700c) stands out as a practical, reliable option for anyone looking to make this upgrade, combining durability, performance, and user-friendliness in a single package.
Durability: Built to Last for Daily Use
A conversion kit’s longevity depends on the quality of its components—and this one delivers. The rear hub wheel features a double-wall aluminum alloy frame, a material prized for its strength-to-weight ratio. Unlike single-wall rims, which are prone to warping under stress, the double-wall design adds rigidity, making it ideal for potholed city streets, gravel paths, or regular commuting. Complementing this is the high-carbon steel spoke set, which provides exceptional stability and resists bending even under heavy loads.
The kit’s maximum weight capacity of 220 lbs (100 kg) means it’s suitable for riders of varying sizes, from casual users to those who carry bags or gear on their commute. One Amazon customer, who uses the kit for an 8-mile daily round trip, noted: “I’ve had this wheel for three months now, and it’s held up perfectly. No loose spokes, no rattles—just solid performance every day. The build quality is way better than I expected for the price.”
This durability isn’t just about strength—it’s about peace of mind. You won’t have to worry about frequent repairs or replacements, even with regular use.
Powerful, Silent Motor: Effortless Assistance for Commutes and Short Journeys
At the core of the kit is a 48V brushless, toothless rotary fly hub motor—a choice that balances power, efficiency, and quiet operation. Brushless motors are known for their longevity (no friction from brushes means less wear) and low maintenance, while the “toothless” design eliminates the whirring noise associated with some e-bike motors. The result? A smooth, near-silent ride that won’t disturb neighbors or fellow cyclists.
Available in 1000W (with a 1500W option for extra torque), the motor provides enough power to tackle hills, headwinds, or long stretches of flat road without breaking a sweat. It’s compatible with both regular bicycles and mountain bikes, meaning you can convert the bike you already love—whether it’s a commuter hybrid or a rugged trail bike.
A 5-star reviewer who converted their old mountain bike said: “The motor is a game-changer for hills. I used to dread the 1-in-10 incline on my way to work, but now I zip up it without even shifting gears. And it’s so quiet—I forget it’s there until I need an extra push.”
This motor isn’t just for speed, either. It’s designed for efficiency, so it won’t drain your battery unnecessarily—ideal for riders who want to maximize range.
Easy Installation: No Expertise Required
One of the biggest fears about e-bike conversion is complex, time-consuming installation. The TOOJUN kit addresses this head-on with a design that’s beginner-friendly—most users complete the process in 1 to 2 hours with no specialized tools.
Included in the package are:
- A detailed, step-by-step manual (with clear diagrams for wiring and assembly).
- All basic accessories (controller, throttle, brake levers, pedal assist sensor, and cable ties).
The kit’s simplicity is a hit with first-time converters. “I’m not mechanically inclined at all—my idea of ‘fixing’ a bike is inflating a tire,” said one user. “But I followed the manual, and it took me just 90 minutes to install. When I got stuck on the controller wiring, the customer support team emailed me a video tutorial within an hour. No stress, no hassle.”
Even if you’re new to e-bike conversions, you won’t feel overwhelmed. The kit is designed to be accessible—because upgrading your bike should be fun, not frustrating.
Multifunctional Accessories: Convenience and Safety in One
The kit’s accessories aren’t just add-ons—they’re designed to enhance your riding experience and keep you safe. Here’s what stands out:
1. LCD8H Meter: Real-Time Data at a Glance
The LCD8H digital display is a critical tool for e-bike riders. It shows:
- Battery percentage: Avoid “range anxiety” by knowing exactly how much power you have left.
- Current speed: Stay within speed limits or track your progress.
- Total distance: Log your miles for fitness or commuting goals.
- Single trip distance: Perfect for tracking short errands or weekend rides.
The display is bright and easy to read in direct sunlight, so you won’t have to squint or stop to check your stats. “The LCD meter is a lifesaver,” said a commuter. “I know exactly when to charge my battery—no more panicking if I take a detour.”
2. Thumb Throttle: No Need to Replace Grips
Unlike some conversion kits that require you to swap out your handlebar grips for a throttle, this one uses a thumb-operated throttle that attaches directly to your existing grip. It’s ergonomic, intuitive, and preserves the comfort of your bike’s original setup. “I hate changing grips—they never feel the same,” said a user. “This throttle fits right on, and I barely notice it until I need it. Perfect.”
3. Power Cut-Off Brake Levers: Safety First
Safety is non-negotiable, and the power cut-off brake levers deliver peace of mind. When you squeeze the brake, the levers send a signal to the controller, instantly cutting power to the motor. This prevents accidental acceleration (a common hazard with some e-bikes) and ensures you have full control in emergencies.
A parent who converted their child’s bike (note: the kit is listed for “child” use, but always follow safety guidelines) said: “The brake levers are a game-changer for kids. If my son hits the brakes suddenly, the motor stops right away—no surprises. I don’t have to worry about him losing control.”
What’s in the Box?
The kit includes everything you need to convert your bike—except the battery (a standard omission, as riders often prefer to choose a battery that matches their range needs). Here’s the full packing list:
- 1000W Motor Rear Hub Wheel (700c size, compatible with 26-29-inch bikes).
- Intelligent controller (manages power flow to the motor).
- Twist/thumb throttle (no grip replacement required).
- Power cut-off brake levers (for front and rear brakes).
- Pedal assist sensor (activates the motor when you pedal, for a more natural ride).
- Cable ties (to keep wiring tidy and prevent tangles).
One user summed it up: “All the parts were there—no missing screws, no broken pieces. I just picked up a 48V 15Ah battery from a local shop, and I was ready to go. It couldn’t be easier.”
Customer Feedback: 5-Star Ratings Speak for Themselves
Amazon reviewers have given the TOOJUN kit a perfect 5.0 out of 5 stars—and their comments highlight why it’s a top choice:
- “My commute time dropped from 45 minutes to 20. The motor is powerful enough to keep up with traffic, and the battery lasts all week. Best investment I’ve made this year.” (Commuter, 1000W model)
- “I converted my mountain bike for trail rides. The motor handles loose gravel and steep climbs like a champ. And it’s so quiet—I can hear birds while I ride!” (Recreational rider)
- “I was worried about durability, but after two months of daily use, it’s still as solid as day one. No issues with the motor, no loose spokes. Worth every penny.” (Casual user)
- “Installation was a breeze. The manual was clear, and customer support was responsive. I’m not a tech guy, but I felt confident the whole time.” (First-time converter)
These reviews aren’t just positive—they’re specific. Users praise the kit for solving real problems: cutting commute time, handling tough terrain, and being easy to install.
Who Is This Kit For?
The TOOJUN conversion kit is ideal for:
- Commuters: Save time and energy on daily trips to work or school.
- Recreational riders: Add power to mountain bikes or hybrid bikes for trail rides or weekend adventures.
- Budget-conscious users: Avoid the £1000+ cost of a new e-bike by upgrading your existing one.
- Eco-friendly riders: Reduce your carbon footprint by using an e-bike instead of a car for short trips.
Final Thoughts: A Reliable Upgrade for Your Bike
The TOOJUN Electric Bicycle Conversion Kit (1000W-700c) checks all the boxes for a great e-bike upgrade:
- Durable construction that withstands daily use.
- Powerful, silent motor for effortless riding.
- Easy installation for beginners and experts alike.

Just remember: you’ll need to purchase a 48V battery separately (most users recommend 10-20Ah for daily commuting). Once you have that, you’re ready to hit the road with a faster, easier, more enjoyable ride.
