Excellent service from DJ when I bought my wife a Kalkoff electric bike for her birthday at their stand at the Shepton Mallet Motorhome Show. Nothing was too much trouble and he lent us a demo bike to take on holiday abroad for a month whilst her new one needed key replacements which had to be obtained from Germany. For both the demo bike and the new one DJ fitted the bike to her in terms of saddle and handle bar adjustments and explained the use of the controls, display, lock and battery charging. Both the demo and new bikes had to be delivered to us involving 2 round trips of about 200 miles. I cannot speak highly enough of DJ and of Bike UK - Bristol.
