Once you have purchased your new bike from us, it will be put into the build queue for one of our workshops. Your bike will be built and will undergo a Pre Delivery Inspection (PDI) by one of our expert mechanics. A PDI is a checklist that the mechanic follows to confirm that all parts of your new bike are up to our high standards.

Next, your bike will be prepared for shipping. Padding is used on all the necessary areas and your bike is loaded into a sturdy cardboard bike box. All the necessary paperwork and accessories will be packed inside too. Most of our cardboard and packaging are recycled from incoming deliveries. Bikes are usually delivered by DPD within the UK.

In order to package your bike safely, you will need to do a small amount of assembly when it arrives. It can vary from bike to bike, but usually you’ll need to: fit the front wheel, install the handlebars and fit the pedals. Please note that not all bikes come with pedals - please check the specification on each bike, we’ll include it on there.

Product Description

Resplendent in silver or 'shake polish' the HSD S+ is packed full of the best riding features to make urban riding and living easier. A Bosch Performance Line motor and 500Wh battery offer up to 74 miles of riding before a charge is needed, more than enough for at least a couple of days riding we'd say!

The bike's gears are from Enviolo, with shifting happening in an enclosed hub and automatically when you ride - one less thing to worry about if it's raining, you want to get home and are faced with an upcoming brute of a hill. There's no standard bike chain either - a Gates Carbon CDX belt drive requires less maintenance and cleaning plus you won't have to worry about an oily stain on your best chinos either. 

Other features of note include a suspension fork and suspension seatpost for extra comfort on rough city roads - don't miss the Magura hydraulic disc brakes either, powerful stoppers if a red light or pelican crossing approaches.
