Design and workmanship
The MOONCOOL TK1 makes no secret of its purpose in its design. It's functional, featuring a low step-through, a wide rear, and plenty of luggage space.
The TK1 can be folded at the handlebars and via a folding mechanism on the frame, which allows for somewhat space-saving storage. However, don't expect miracles; even when folded, it remains large and, more importantly, weighs over 40 kg.
While this provides stability, it becomes quite noticeable when maneuvering without the engine. The high weight should be taken into account, especially when moving the vehicle in tight spaces or during loading.
The frame itself combines aluminum with steel elements and appears robust overall, which is appropriate for the high payload capacity of up to 205 kg. The workmanship is acceptable, but details clearly reflect the price range. Attachments seem simpler, some fasteners are functional rather than elegant, and the seat adjustment doesn't always hold perfectly.
There's nothing else to criticize about the basic equipment. Front and rear baskets, lights with brake light and turn signals, and details like a parking brake are all included. It also features well-cushioned 20 x 3 inch tires, which further emphasize its suitability as an e-trike.
engine and driving behavior
The TK1 is available in two versions: a road-legal (StVZO-compliant) version with a 250-watt rear motor that can deliver up to 500 watts peak power for short periods; and a more powerful 500-watt motor with a 1000-watt peak power in other regions. Pedaling power is measured using a standard cadence sensor, not a torque sensor.
This means that the motor delivers power as soon as the crank is turned. While the typical delay between pedaling and power delivery is noticeable, it is relatively small here. Similarly, the assistance is not jerky and remains pleasantly consistent.
The torque is approximately 45 Newton meters, and the speed is limited to 25 km/h as specified. There are five support levels, which are sensibly graduated and allow for good control over speed and power output.
The riding experience is different from that of a normal e-bike. You have to be more deliberate when cornering, because instead of leaning into the turn, the TK1 remains rather rigid.
The differential on the rear axle also plays an important role here. It ensures that the two rear wheels can rotate at different speeds, which makes the handling significantly more stable and controlled than with simple trikes without this technology.
Minor bumps, curbs, or potholes are absorbed by the wide 20 x 3 inch tires and the front suspension fork. However, there is no true rear suspension, which is why it is primarily suitable for city riding, bike paths, or paved gravel roads.
Gentle inclines are no problem for the TK1. However, it lacks the power for steeper or longer climbs, especially if the rider is heavier or carrying a heavier load. There's no conventional gear system to compensate for this. In such cases, the only option is to dismount and push.
Braking is achieved via disc brakes, which provide predictable stopping power even under load. The design with two rear wheels distributes braking force more evenly than a conventional e-bike, resulting in better stability.
Transport capabilities
The front basket is ideal for anything you need to quickly put away. A backpack, handbag, or a few groceries from the bakery will all fit. The large rear basket, on the other hand, is designed for bulkier items, easily accommodating two full shopping bags, crates of drinks, or even large items like cardboard boxes.
Driving to the supermarket, throwing the shopping in the back, maybe putting the backpack in the front and rolling home relaxed would be a typical scenario for the TK1, for example.
However, there are clear limitations in everyday use. The TK1 is significantly wider than a normal bicycle, which means that narrow bike paths, bollards, or narrow passageways can quickly become obstacles. It also requires more space when parking, and carrying it down to the basement is practically impossible at over 40 kg.
Battery and range in everyday use
The TK1's battery has a capacity of 36 V and 20 Ah, which corresponds to approximately 720 Wh. It is located behind the seat tube, below the rider, and is removable, which is a huge advantage given the bike's considerable weight.
MOONCOOL states a range of up to 70 km. Realistically, you should expect more like 40 to 60 km, as riding style and payload play a significant role, meaning the range can vary more than with a conventional e-bike. Charging time is around 6 to 7 hours, which is typical for this class.
