Update.
Had my Cube reaction hybrid pro 500 5 weeks.
No problems at all once I had ironed out the pre delivery woes from the apathetic store I got it from.
260 miles and I love the thing.
Mostly doing cycle routes,old railways etc but some roads so have front and rear lights,bright ones so I'm seen a little bit better.
Wish I'd got a full suspension bike as at speed some trails bounce me about but as a £2000 bike as it is I'm in no way disappointed.
I am doing 25/30 mile trips and still having three bars left though I'm not using turbo or emtb much mostly tour and using the smooth shifting gears a lot so figure on a range of 40+ or 25 ish in the woods climbing more.
The bike is very heavy but this is not noticed on the move but steps and styles etc are awkward.
Brakes strong the whole thing works wonderfully as you might expect for the price but it puts me in places I thought my poorly knees wouldn't take me and like my old Alfa I like looking at the cube...it looks cool,goes great and at 0% finance well they are giving it away for free.
