I purchased this in a hurry because my other bike got stolen :(. I don't know why, because it was rusty, the saddle was damaged and the brakes were non-existant.
Anyway, I needed a new bike straight away, found this on Amazon, did not expect too much of it but was pleasantly surprised! Not only did it arrive in no time (bought Sunday night, arrived Tuesday morning, delivered by a charming postman), but it was easy to assemble and it really does the job.
Now, for this price don`t expect a top quality bike, but it really gets you from A to B (office to train station in my case), fast (18 gears), safe (strong brakes) and that`s all what I need. It is not light but not too heavy either - for a mountain bike just the right weight.
The saddle is very comfortable and it comes with some reflection lights.
Very happy, can highly recommend it!
