Rockrider 500

Great bike for the money

None as yet

used for 1 week or less Originally intended to buy a Carrera Subway but discovered the Rockrider 500 and went for it.
First day out was getting used to cycling again after twenty or so years, then second ride was out for five hours.
A few tweaks here and there and I had everything in my ideal riding position.
This is an amazing bike to ride, smooth gear changes without any grinding or clunking and the powerful disc brakes give you so much stopping power and confidence, though they squeak when its wet, don't know if all disc brakes do this?
I like the plastic toe clips which keep your feet in the correct position on the pedals.
The staff at Decathlon in Wednesbury were really helpful and patient with me and helped me buy the bike I wanted, not sell me another.
I will (and already have) recommend Decathlon and the Rockhopper 500.
Thank you Decathlon and keep up the good work.

used for 1 week or less This is the best bike I've owned in a long time. I'm nearly 50 now and I just needed something to M.O.T. myself (lol), and this bike is good for that. I've also been admired a lot more by the ladies in my area while riding it around so I guess this bike is a bit of a cycling babe magnet too.
My wife will definitely need to buy one too or she's in danger of losing me to a cute lady rider, once I loose my gut of course:-).

used for 1 week or less Absolutely a great bike for the price. This was a replacement bike as my former one was stolen from outside my home. The service was absolutely great was told 20 minutes so had enough time to get the few accessories I needed for this bike. I've ridden it and it rides well, coping with fast gear changes, slow and fast corners and able to cope with slow controlled riding to avoid people. The gear changes are great they feel chunky and you can feel them work. The tyres are very grippy.
My only problem are the gear shifters as the up shifter is really far back on the brake/gear fitting. but overall great bike.
Hopefully its the same as you guys too
