Mooncool TK1 Folding Electric Trike Review | Cool & Colorful

Our Range Test and the TK1 Folding Electric Trike’s results are explained and listed above, along with a graphical comparison of its range with similar models we’ve tested.

Other electric trikes we’ve tested, including the best electric tricycles on the market, averaged 26 and 45.5 miles using batteries that averaged roughly 608 watt hours. With a larger 696-Wh battery, we were not surprised that the TK1 kept moving longer.

This trike’s low-power Range Test result was closer to average than its PAS 5 result, which means that riders choosing to use its highest power mode will likely travel much further on this model than on most of the others we’ve tested.

Looking a bit deeper into the data, we were impressed by the efficiency of the TK1’s 500W motor and 696-Wh battery. Based on its specs, we estimated that its high-power range test would last for about an hour and 25 minutes, yielding roughly 19 miles. Our test rider spent an extra hour and 14 minutes on the path and covered about an extra 17 miles!

Most trike owners we’ve interacted with tend to take relatively short trips, so we expect the majority of users to get quite a few rides out of the battery before needing to recharge, especially when sticking to moderate speeds.

With such great test results, however, TK1 owners also have the option to stay moving for extended rides. When the battery finally needs recharged, Mooncool’s 2-amp charger will power up the trike in a little over seven hours.

We tested the TK1’s ability to climb hills in a couple of different ways. First, using our formal Hill Test methods and location, as described above. Second, at a location nearer to our office, I tested the trike using similar methods both with and without 60 lbs of cargo in the rear basket.

At Hell Hole Trail, other trikes we’ve tested averaged 1:45 in the throttle test and 1:35 when pedaling, so in each case, the TK1 differed by only a few seconds. The Mooncool’s results fall within our margin of error for this test, so it’s fair to say that the TK1 Folding trike has average climbing performance based on the numbers.

Two major factors influencing this test are weight and peak motor output (both watts and Newton meters of torque). At 95 lbs, the TK1 is on the heavier side when compared with our current trike average of 87 lbs.

The TK1’s motor peaks around the norm, or maybe slightly above, at 1000W. It produces 55 Newton meters (Nm) of torque, which is a little on the lower side (66 Nm is average), so all three factors seemed to balance out.

At our secondary location, called Pilot Hill, my respective throttle and pedal times without cargo were 1:32 and 1:29. I noted that the trike climbed quickly and confidently over this hill, which is less extreme than Hell Hole, but still challenging for many e-bikes and trikes.

When I added 60 lbs of weight to the rear cargo rack, my results slowed to 1:45 when using the throttle and 1:33 in PAS 5. Pedaling felt similarly easy to riding without cargo, so I was not surprised to see that there were only a few seconds of difference in my times.

Based on our testing, we can confidently say that the TK1 has the ability to handle steep hills, even when carrying a substantial load of groceries or a couple of bags of pet food. The throttle should be able to do all the heavy lifting on most hills, but riders looking to speed things along can do so by adding a little extra leg power.

Most importantly, they likely won’t have to pedal very hard to get the job done.

The TK1 Folding Electric Trike has a Star Union hydraulic disc brake system with 2-piston calipers, a single 180mm rotor on the rear axle, and a second 180mm rotor on the front wheel. We measured this system’s stopping power using the process above, with the trike’s final score being a respectable 13’7”.

Comparison with other trikes is fairly difficult because every other model we’ve tested has been a little different.

For example, some trikes have topped out at 14 miles per hour, while others have had a 16-mph maximum. Some trikes were equipped with mechanical disc brakes, some employed hydraulic systems, and still others used coaster brakes. Many had two brake rotors, a few have had three, etc.

The TK1’s setup is similar to a couple of other models we’ve tested, but it weighed about 10 pounds more, which makes it a bit tougher to slow down.

Mooncool seems to have accounted for the TK1’s added weight, however, by equipping it with rotors that are 2.3 millimeters thick (versus the more common 1.8 mm thickness). Thicker rotors are better able to disperse heat buildup, resulting in faster and more effective braking.

Compared to those models that were most similar, the TK1’s average stopping distance was a few inches beyond the others. Based on my experience, I believe the difference was more due to the TK1’s knobby tires than its brake system, as knobby tires have less grip on paved surfaces than smoother street tires.

Going by feel, I found the TK1’s brakes to be safe, powerful, and effective. I appreciated the extra stopping power granted by its thick rotors, as its brakes did a great job of keeping my speed controlled when riding downhill at relatively high speeds when carrying 60 pounds of added cargo in the rear basket

The trike always felt safe and well under control, so its brake system earned our approval.

Ride quality is a complex subject. It’s comprised of many individual elements that summarize how a bike feels to ride. As we explore this section, I’ll explain these elements in detail.

Starting with sizing and fit, the TK1 Folding trike has a single frame size intended for riders from 5’0” to 6’3”. I am 5’11” with a 31” inseam and found its proportions comfortable and its range of adjustment accommodating. I was able to set the saddle and handlebar height for proper leg extension and comfort, and I appreciated the trike’s relaxed reach.

The trike’s extended seatpost offers 13” of saddle height adjustment, which is more than adequate for its recommended height range. It also offers a modest but helpful 2.5” of adjustment in handlebar height with a telescoping and collapsible stem.

As I mentioned previously, delta-style trikes (one front wheel and two rear wheels) have some unique handling characteristics. We recommend slowing down significantly when cornering and leaning into turns to avoid tipping up on two wheels, which is a concern with all trikes of this style. These characteristics may take some getting used to for riders who are new to trikes or more used to riding bicycles/e-bikes.

The Mooncool trike’s rear wheel spacing is relatively narrow in comparison to many others we’ve tested (roughly 25.5 inches, while most others were above 26”). As such, I found that it tipped up on two wheels fairly easily, but it didn’t feel unsafe. The TK1 also felt much more planted when I was carrying some extra weight.

With a step-thru frame, I noticed that there was some frame flex that resulted in a noticeable sway while riding. This flex and sway has been present on most trikes I’ve tested, so it wasn’t abnormal or alarming, but it was noticeable (and worth mentioning).

Overall, I found the trike comfortable—the thick and shock-absorbing saddle, in particular, was a highlight—but I have a couple of points of critique about the seatpost and seat tube to address.

At least on our test trike, the frame’s seat tube was larger than the seatpost’s diameter, so it came with an aluminum shim inside to help make up the difference in sizing. Even with the seatpost clamp tightened down to where it was difficult to close, the saddle kept sliding down during our testing; we encourage Mooncool to find a more secure solution.

Additionally, we found that if the saddle dropped, the long seatpost protruded below the bottom of the frame and separated the wiring connector between the battery and the display. When this happened, the trike would not turn on until the plugs were reconnected. Once we discovered the source of the problem, it wasn’t a huge concern, but riders on the shorter end of the spectrum who need the saddle low may want to consider swapping to a shorter seatpost. Alternatively, cutting some length off the standard seatpost should prevent the wiring from becoming disconnected.

Returning to the list of features I appreciated, I was pleased to note that the TK1’s tires added both a layer of cushion to the ride and an extra level of versatility. We expect most riders will stick to paved roads and paths, but the knobby tires add grip and traction for unpaved surfaces such as smooth dirt roads or gravel multi-use trails.

I also appreciated the trike’s overall simplicity. The single-speed drivetrain requires no shifting, so once the rider’s assist level is set, there’s more time to appreciate one’s surroundings instead of constantly changing gears.

Additionally, I found the turn signals and horn easy to reach and operate from the ergonomic rubber grips. I also really liked the display; it shows important data in an organized manner without being too complicated. I appreciate a good user interface!

Considering that this was our first experience with a product from Mooncool, I wasn’t certain what to expect from its feel and performance. I had high hopes based on the TK1 Folding trike’s features, but I took a cautious approach considering its price, as we’ve had mixed results from budget-tier products.

In retrospect, our experience with the TK1 was good overall. We noticed a few tradeoffs in terms of ride quality, which is not unusual with affordable, entry-level e-bikes and trikes. It could be a little squeaky and creaky at times, and we identified a couple of areas with room for improvement, but its ride and performance showed that it has a solid foundation.

Looking back over our test results, the trike had a well-balanced pedal assist system with controlled speeds and good brakes. Its range was noticeably better than average, and it demonstrated solid climbing power. The TK1 was capable of hauling an average-sized payload with ease, and it also had a comfortable ride and an approachable user interface.

Based on our overall experience and the data from our standardized performance tests, we feel comfortable recommending the TK1 for leisure and utility purposes. Those seeking a budget-friendly electric trike with personality should consider it, especially if range is an important factor!
