Hello! How can we help you?

What wheel size is best for an outdoor walker?

For an outdoor walker, wheels of 12–14″ (31–36 cm) give the best balance of comfort, manoeuvrability and stability — they roll over uneven pavements, gravel, grass and small obstacles far more easily than small, hard castors. Trionic offers three wheel sizes so you can match the walker to your terrain.

Trionic wheel sizes:

  • Walker 9er — 9″ / 23 cm SuperSoft solid tyres: most compact and puncture-free, ideal for pavements and easy transport
  • Walker 12er — 12″ / 31 cm pneumatic tyres: the everyday all-rounder for mixed terrain
  • Walker 14er — 14″ / 36 cm pneumatic tyres: maximum roll-over for rough trails and forest paths
  • Trionic Veloped — three wheels with large pneumatic tyres and a patented Climbing Wheel for true off-road terrain

  • Great walker! Trionic is the brand I recommend!!…

    I’ve been using my walker since June 2025 and it has helped immensely. It is a workhorse! I can take it across lawns, curbs and gravel without hesitation that stopped my two former walkers cold. There is no better feeling than to SIT safely and comf…

  • The Veloped Has Changed My Life - Yippee!…

    My bicycle accident, four years ago, left me with such poor balance, that I struggled to walk with a stick. In fact, I found myself very reluctant to walk even short distances. There is the standard red rollator, something many elderly people have, b…

  • Les Connett…

    I wanted an all-terrain rollator and researched the market, eventually selecting the Trionic 12er. The design and construction are impressive, and I have been very pleased with the functionality of the product. Expensive, but very good for my purpose…

  • Oh my, the places I can go!…

    I love the Veloped, it changed my life! I am not afraid of walking on grass in my backyard or grandchildren’s athletic games, unpaved trails, let alone any kind of slightly uneven surface, think raised sidewalks, downed tree & plant debris scattere…

  • Walker 14er - Very useful product…

    I have used the Walker several times.
    It can be easily assembled and disassembled without help and can be stored in the trunk.
    It is light, thanks to the synchronization of the front wheels and the large air tires, and it is much easier to walk eve…

    I am absolutely thrilled with my Walker 12er. A fantastic finish, a modern design. It has attracted a lot of attention both in public places and on the Underground, attracting praise and appreciation for both its appearance and workmanship, thus conf…

  • The Veloped is a great invention...…

    The Veloped is a great invention and fills the gap that other conventional rollators cannot. The large smooth-running wheels and the twin wheel in the front make the ride wonderfully easy and provide support and, most importantly, allow you to walk m…

  • Fantastic product!…

    The Veloped Tour is the Rolls Royce of rollators (infact it isn't correct to call it a rollator-its so much more) I thought long and hard about making this purchase as it isn't cheap but am so glad that I decided to buy it. For someone like me who ha…
