All Terrain Cycles are now offering a Home Delivery service.
Our Cytech qualified mechanics will first make sure that your bike is fully checked and ready to ride.
Then we will deliver it completely assembled direct to your home or place of work where we will set up your bike for your personal needs and answer any questions you may have. All for just £50.00.
Our delivery map indicates a general area, however, if you do not see your location on the map please call us on 01274 588488 to discuss a special delivery.
After the first few weeks of use, the whole bike will settle down. As a result, the gears may need tweaking, some nuts and bolts may need tightening and you may well need to check the adjustment of the saddle and handlebars.
One of our Cytech qualified mechanics will hand build your bike leaving only a few minor adjustments for you to do once your new bike arrives. Our mechanic will also complete a rigorous Pre-Delivery Inspection (PDI) before carefully re-packing for shipping to you; but in order to fit the bike back into its box for delivery, some disassembly has to be done. Re-assembly of these parts should be straightforward and should not take very long.
