I bought a B'TWIN TILT 100 folding bike 2 months ago... My advice: don't buy it! Worst purchase ever! And poor customer service: when I bought the bike, the team hadn't checked the tyres' pressure so I had to take care of it and inflate the tyres once at home ; the saddle was not properly fitted so even though I could use the bike, the saddle got damaged because of this... I use the bike every day in London and the chain comes off at least 3 or 4 times a day! I took it back to the store but they told me they could not do anything about the saddle nor about the chain... in short, the bike is not reliable (and even dangerous, so I got rid of it... just 2 months after I bought it), it's very disappointing and the Decathlon team wasn't helpful before/after the purchase!
