We bought 2 hunter bikes a few weeks ago, they are brilliant. Thank you everyone at access bikes for your wonderful service and patience.
The bike is brilliant for me. I am a below-knee amputee and am able to return to cycling at last! Hills are no longer a problem.
I have purchased 2 electric bicycles from Axcess Cycles in the past 6 years. I currently have a Raleigh Motus which I am delighted with. The purchase and after sales service experience has always been outstanding. Peter is very helpful and I have no hesitation in recommending Axcess Electric Bikes.
