Poor quality - V-BRAKE CALLIPERS bent

This could have been very dangerous for my son, the V-BRAKE CALLIPERS bent leaving him with no front breaks. We bought the bike for my sons birthday last year and he has barely used it. Plus the stand which we bought with it and got fitted by Decathlon basically feel apart pretty much straight away. Dangerous and rubbish

Best customer service

This is a gift for my son so he hasn’t used it yet. The lady who helped me in the shop, I can honestly say, was the best customer service we have received ever! She pulled out every bike, gave us advice, nothing was too much trouble and I did not feel rushed. I even emailed before I purchased to make sure I was ordering the right one and she sent me images of the bikes. Would only ever buy from here now. Thanks so much

ST 100 Rockrider

Have only been out 4 times so far. This bike is very nice in styling. However, the supplied seat is the worst seat for comfort I've ever had. Very uncomfortable after only 20-30 minutes. I've stuck with it to see if I could adapt, but no. Easily changed though. The brakes seem to be very responsive and reliable. Gear changing is very slippery. Sometimes resulting in a loss of footing. Also now and then, a strange knocking appears, seems to be in the pedal rotation, I'll mention this at service. Hoping these issues can be sorted at the free 3 month service. Overall so far, very happy.
