The feelings for this bicycle are mixed. I will try to include the main pros and cons for anyone interested in buying it.
Pros:
1. Speed. Routes that previously took me 20 minutes on foot, I can now do in 4 minutes with the bicycle. Incredible time savings, especially if you use it to go to work. The description says that this bicycle can reach 25 kilometers per hour, but it easily reaches 30 kilometers per hour on a straight road, and even 40-42 kilometers per hour or more downhill (but don't try it).
2. Convenience. The pedal assistance is magical. With just two and a half pedal rotations, you feel a push, as if you're flying. It goes on its own! Your legs don't get tired like on a regular bicycle. You don't sweat, you don't get physically exhausted. The bicycle moves, and you only need to pedal occasionally to maintain the assistance.
3. Uphill. The bicycle has 5 levels of assistance. You can easily climb a steep uphill using just level 1 - you should try the other 4 as well. Just for uphill rides, it's worth every euro. People told me this, and I didn't believe it. It's a technological wonder that leaves you in awe every time you climb a long and difficult uphill in seconds. You wish you were in front of an uphill!
4. Portability. It folds so easily. It doesn't take up more space on the bus than a regular suitcase with wheels. You can take it everywhere. It's lightweight, around 13 kilograms. It charges in a standard socket in just a few hours. You can take it on vacation and have your own taxi...
Cons:
1. Safety. Unfortunately, the risk of accidents is VERY high. The wheels are tiny and delicate, so if you encounter a pothole, a stone, or debris on the road, you can easily fall. The brakes are completely inadequate, especially downhill. I would describe them as practically non-existent. I don't recommend going faster than 15 kilometers per hour downhill. If you brake downhill at a speed over 20 kilometers per hour, whether you do it very gently or slightly abruptly, your life is in danger. It's a VERY serious disadvantage: this bicycle is made for straight roads or uphill rides on roads with moderate traffic. I don't recommend it even as a joke on a highway. Going downhill, it's in your hands. If it had normal-sized wheels and decent brakes (disc brakes), I would give it 5 stars. Especially for safety alone, I give it half a star.
2. Battery life. I consider the advertised maximum distance of 70 kilometers completely utopian. With a full charge, the bike can go 40 kilometers, maybe 50 at most, if you ride exclusively on smooth roads. And I mean with intermittent use of assistance and always on the 1st level of the 5-level scale. If you use the assistance permanently and on the 5th level, I highly doubt it will last for 20 kilometers on a single charge... Let's be honest. 70 kilometers, simply NOT.
3. Weather and terrain conditions. In rainy conditions, it's out of the question to ride on a wet road with these short and thin wheels. Also, dirt roads and generally non-paved roads are not suitable.
Overall, this little bicycle is a solution for short trips. It saves you time, money, and energy in the city. It's not intended for anything else. Neither for long distances, nor for difficult areas, nor for villages with uneven roads, nor for highways, nor for sports, nor for speed races. If you have low expectations, it will cover you. If you are looking for something more, definitely look for a bicycle with larger wheels and a more serious braking system.
UPDATE. After 4 months and with the odometer already showing 500km, I have to add:
-The terrible brakes still limit you from reaching speeds above 30km/h, and many times you need to ride with a slight brake applied even on straight roads, in order to anticipate soft braking in case of an approaching vehicle. You learn to ride with the brake constantly applied.
-With simple assistance usage at 1/5, the battery lasts a maximum of 20km distance, tested. And I say this as a woman weighing 42kg. For a man weighing over 70kg, speed 1 is not enough. You have to switch to 4th or 5th gear to get a push, and at that point, the battery lasts less than 10km per charge. If you are tempted by the advertisement claiming 70km endurance, believe me, for an average-weight person, 15km is the average.
-It charges exactly in 3.5 hours, full. You don't go anywhere without the charger with you.
-The tires need to be pumped every two weeks, as a standard.
-Although it is made for asphalt and flat surfaces, it has taken me unscathed through dirt roads in Crete, uneven terrain, uphill and downhill slopes, here at the foothills of Psiloritis - and whoever understands, understands.
-The risk of accidents decreases over time. If you are used to a conventional bicycle, it takes you a month to adjust, but then you love it. It's all a matter of adaptation.
