Vitus Nucleus 275 V HT Bike - Shimano Tourney

The Nucleus range is the entry-level mountain bike range that punches well above its price-point. Designed for progression, the Nucleus will help you learn the basics or hone and master your trail skills. Winning MBR’s “£500 Hardtail of the Year” award only encouraged Vitus to make the Nucleus better than ever.

Updated Aluminium Frame

Because there’s always room for improvement, Vitus returned to the drawing board and came back with a brand-new alloy frame which follows the DNA and core characteristics of the Vitus Sentier. Refined with their trail-oriented geometry, the Nucleus is now longer, lower and slacker than before. With revised geometry, improved stand-over clearance and internal dropper post cable routing, this entry-level aluminium MTB is like no other: it’s a bike that owes a lot to its big sibling, but more than capable of finding its own path.

Easy Assembly

When you order a bike, one of our trained mechanics will carefully prepare and pack your bike for shipping. Upon delivery, the assembly is simple and all necessary tools are conveniently included in the box.

Depending on the delivery service and destination, bikes will either be delivered in a large or a small box. Below is a guide as to how your bike will arrive:

  • All bikes for delivery within the UK and Republic of Ireland will be delivered in a large box, except for kids’ bikes and BMX bikes, which are always delivered in manufacturer's boxes.
  • All bikes for delivery within the EU on a standard service will be delivered in a large box. If an express delivery option is chosen, your bike will be packed into a small box. Again, the exception is kids’ bikes and BMX bikes, which are always delivered in manufacturer's boxes.
  • All bikes for worldwide delivery outside the EU will be delivered in small boxes.
