Three wheels, a folding frame and electric assistance make the Mooncool TK1 Folding Electric Trike an interesting alternative to a conventional e-bike. It is designed around stability, comfort and practical everyday riding, with enough carrying capacity to make it useful for shopping, commuting and short trips.
But an electric trike is a very different proposition from a two-wheel e-bike. So, is the Mooncool TK1 a sensible choice for UK riders?
We take a closer look at its design, motor, battery, comfort, practicality and overall value.

What Is the Mooncool TK1?
The Mooncool TK1 Folding Electric Trike is built for riders who want the extra stability of three wheels without giving up the convenience of electric assistance.
Its design combines a step-through-style frame, wide 20-inch tyres, a suspension fork and a large padded saddle. Mooncool also positions the TK1 as a practical mobility option, particularly for older riders who may prefer a more stable platform than a traditional bicycle.
The folding frame is another useful feature. It makes storage easier, although the TK1 is still a substantial machine rather than something you can casually carry under one arm.
Motor and Battery Performance
The UK version currently listed by Mooncool uses a 250W helical motor, with peak power of 500W and up to 45Nm of torque. It is paired with a removable 36V 20Ah battery and has a claimed range of up to 45 miles.
For everyday riding, this should provide enough assistance for flat roads, moderate inclines and local journeys.
Real-world range will naturally depend on factors such as rider weight, terrain, temperature, tyre pressure, assistance level and riding style. Independent testing of TK1 variants has also shown that actual range can differ from manufacturer claims.
One benefit of the removable battery is that you don’t necessarily have to take the whole trike near a charging point.
Stability and Ride Comfort
This is arguably where the TK1 makes the most sense.
Three wheels provide a naturally different riding experience from a bicycle. The wide 20 × 3.0-inch tyres, suspension fork and substantial saddle are intended to make the ride more comfortable and confidence-inspiring.
The rear differential mechanism is also an important feature. It allows the rear wheels to behave appropriately while turning, helping the trike feel more controlled through corners.
New trike riders should still take some time to get used to the handling. A three-wheeled vehicle doesn’t lean into corners like a normal bicycle, so slower, controlled turns are a sensible way to start.
Practical Storage
The TK1 is clearly designed with utility in mind.
You get both front and rear baskets, along with a rear rack, giving you considerably more carrying space than a typical e-bike.
That makes the trike particularly appealing for:
- Grocery shopping
- Local errands
- Commuting
- Carrying everyday belongings
- Short recreational rides
The folding mechanism is another advantage for storage at home or transportation, although the trike weighs around 40.8kg net, so lifting it still requires considerable effort.
Brakes and Safety Features
The TK1 uses hydraulic disc brakes and includes an electrical cut-off function. It also comes with a parking brake, which is particularly useful on a three-wheeled vehicle when stopping on an incline.
Mooncool also includes turn signals and a horn, adding practical road-use features that aren’t always found on basic electric trikes.
The combination of wider tyres, three-wheel stability, lighting and braking equipment makes the TK1 feel more focused on everyday utility than outright speed.
What Could Be Better?
The biggest drawback is weight.
At roughly 40.8kg before additional cargo, the TK1 is considerably heavier than most conventional bicycles. That matters if you need to lift it into a vehicle or move it up steps.
The single-speed drivetrain is another compromise. Independent testing has found that pedalling at higher speeds can feel less natural because of the limited gearing.
It’s also important not to confuse the TK1 with a lightweight folding bicycle. The folding feature improves storage, but it doesn’t transform the trike into a genuinely portable machine.
Is the Mooncool TK1 Good Value?
The current UK Mooncool listing shows the TK1 at £1,499.99, reduced from a listed regular price of £2,099.99 at the time of checking. The UK listing also states free shipping, 30-day returns and a one-year warranty.
At that price, the TK1 isn’t an impulse purchase. Its value comes from the combination of electric assistance, three-wheel stability, folding functionality and substantial cargo capacity.
If you simply want the fastest or lightest e-bike, there are better options.
If your priority is stable, comfortable and practical local transportation, the proposition becomes much more interesting.
Final Verdict
The Mooncool TK1 Folding Electric Trike is best understood as a practical electric utility vehicle rather than a performance bicycle.
Its strengths are clear: a stable three-wheel design, comfortable seating, front suspension, hydraulic brakes, removable battery and plenty of storage. The folding frame adds another layer of convenience, particularly for people with limited storage space.
The compromises are mainly its weight, size and relatively simple drivetrain.
For UK riders looking for a stable electric trike for shopping, errands, commuting or relaxed recreational riding, the TK1 is a compelling option to consider. However, anyone prioritising portability, sporty handling or easy lifting should look at lighter alternatives before buying.
Overall verdict: A practical and comfortable folding electric trike for utility-focused riders, with stability and storage being its biggest advantages.
