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

With updated styling for 2021 and that aforementioned motor upgrade, the Tern Vektron is an excellent choice for cyclists looking for a powerful folding electric bike. Indeed, e-folders powered by a Bosch motor are few and far between and the Vektron makes the most of its 400Wh battery and Purion display to deliver a ride range of between 34 and 68 miles. Tern have carefully tilted the bike's battery a tad too, lowering the centre gravity for a better ride.

What hasn't changed in this updated version of the Vektron S10 is its capacity to fit riders from 4' 10" right up to 6' 5" through its telescopic seatpost and adjustable handlebar. Resized in seconds its a bike that can be shared by the whole family. Speaking of which, the integrated pannier rack is compatible with Thule Yepp Maxxi child seats with no further adapters needed - although there is a max gross vehicle weight of 125kg. The rack also doubles as a solid base for you to store the bike once folded.

Other features of note include the 10 speed Shimano gearing for riding on all sorts of gradients, the wide Schwalbe Big Apple tyres for comfort and puncture protection and the Magura hydraulic discs for excellent, stop-on-a-dime braking. Folding the bike can take as little as ten seconds and once collapse the bike measures 41cm x 86cm x 68cm.
