Contrary to what is indicated in the description, the pinion is not made up of 16 teeth, but of 18 teeth. This may seem like a detail, but this difference greatly modifies the transmission ratio. With the 18 teeth, the feeling of grinding is very unpleasant on the flat. To see therefore with a real pinion of 16 teeth, or even 14 teeth. In the meantime, the driving pleasure is not there, and the versatility is not there either (unless you like to pedal in space...).

Surprisingly good for the price

It's really fun to drive. Like a gocart, but as a bike. Added lighting, handlebar bag, folding pedals and transport cover. We'll probably swap the saddle too. Then it is the perfect complement to traveling by train. Folding or unfolding is also very easy. And when folded you can even roll it on a wheel.

When trying the bike on the first day I discovered that the transmission had friction at the bottom bracket bearing or the rear sprocket (shock?)! The mechanic could at least check the bike before delivering it. You can ride but that promises rapid wear. Otherwise this bike seems well designed for a few km a day in town. Its weight allows it to be taken up stairs and its maneuverability is good.

When closing, the brake cables can get tangled. Then the brakes do not work. Since it is currently under warranty, I can tighten it and have the brakes repaired. I don't know how often I can bring it in after the warranty expires.

Foldable bike

Comfortable and practical, very easy to carry, excellent to take on the train.

So that the bike...

For the bike to be perfect, I would have liked wheels that were a little more "all-terrain". The tires are so thin and smooth that I feel worried with every hole or bump 😅.

I have been using the product for about 2 months, it is ideal for flat roads. But even if you are going to use it in a slightly hilly area, I recommend you to take a look at the models with gears. Apart from that, the folding mechanism and other moving parts seemed solid to me. Its weight is among its competitors, and its normal folding size is large enough to fit in the trunk (except for vehicles with LPG)

Handy and compact!!!

for quick and easy use

it is a simple wheel. Recommended for quick use. You can make good progress on flat surfaces (slight inclines ok). Nothing for long distances. Now and then a cable gets caught near the folding mechanism. It is practical nonetheless

Good travel bike...

Good travel bike even if it is still a bit bulky during transport. Good quality

I had a MTB bought at decathlon, excellent. But I decided to change it since the last time I did not give it the necessary use and it was too big for me to save. Find out the "Second Life" plan at Decathlon and I don't regret it at all. The bike is very simple and light, much better for the city than the one I had and the change process was quick and easy. It is comfortable and even though it is for the flat, nothing difficult is done in a city like Barcelona. So far, very happy with the change. The excellent attention, they resolved doubts and I was able to try it before buying it.

Very satisfied with my purchase I find the pleasure of walking around town or type of firm ground very practical and simple to store and disassemble

is it worth it?

A bike for PLN 1,199. I immediately bought folding pedals, because they are not originally like that. The lamps that were attached to it I immediately unhooked, and for the front I gave (I use interchangeably) a gravel lamp (a decent lamp), and for the rear I bought a stronger one. I bought a dedicated trunk for it (quite expensive), a handlebar pad, a plastic (universal) fender for the front (at the back, the trunk and the cheapest pannier / trunk bag placed on it), as well as puncture patches. The whole accessories cost PLN 400, so generally speaking, the bike amounted to PLN 1,600. The drive is single speed. With (my) usual cadence, this translates to an average speed of 15 km/h (flat). When I want to go faster, it requires an increase in cadence. This is my conscious choice. I didn't want derailleurs (and "flying" around them). It accelerates quickly (even up to 25 km/h), although maintaining this speed requires tightening later. It goes under viaducts with no problem. It was intended to be a very simple bike for all everyday situations, when I don't want to worry about the results, performance, or someone is going to steal it from under the block, store, other place. It's small and compact (compared to a traditional road or gravel bike). I'm having a renovation in the stairwell and this bike is perfect for squeezing between buckets, on tiles, between ladders and walls. I've done it since the purchase already 200 km :) The pleasure of driving for me is huge. Reminds me of my very young years when I was riding the Pelican. The features that prevail are handyness, practicality and simplicity. It makes you want to do all those everyday things that previously required walking (or using public transport). I folded it twice. At home, it stands without folding (when I bought it, I wanted it to be small and handy, not that it has to fold). It's not an all-rounder in the sense of "can't do everything". I wouldn't dare attempt 200 km on it at once. I wouldn't drive it through the woods. What did I miss in it? In total, only one thing: that the set includes a wrench to unscrew the wheels, or at least it was available in the store. The saddle is very comfortable for me, and if I additionally wear shorts with a diaper, it's almost luxurious. If I had only one bike, this wouldn't be it. But as a city bike, the second (or third) works best. It works even better when you already have a bike and accessories for it, then you only translate the accessories and the cost decreases (close to the cost of the purchase itself). What is worth knowing? If you mount a rack, you should rather not attach panniers to it, because your shoes will catch on them while pedaling. There are also no mounting holes for a bottle cage. Would I buy it again? Yes. For the sheer driving pleasure it brings. And (following) for the features listed above.
