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

  • Absolutely love my new Trionic 4 wheel……

    It’s so easy to walk with, the 14inch wheels are great for the smaller curbs.
    I like the way that the two front wheels are always together, it makes a huge difference.
    I would certainly recommend this product.

  • Streets paved with old cobblestones…

    My husband had fallen a few times in the last few months, but he still refused to use a rollator. That's why I looked around for a better one than the ones usually offered in German medical shops. I found the Walker and suggested it to my husband. He…

  • Able to walk outdoors again…

    The Trionic Veloped Sport was an excellent purchase. Because of cerebellar ataxia, I am no longer able to walk without a rollator. This device allows me to walk outdoors again, which is huge! It is worth every cent.…

  • Amazing!!…

    Here the Trek 14er comes in. Unlike regular rollators, it's designed to cope with rough/uneven terrain, it's sturdy enough to support me, yet still lightweight enough for me to lift in and out of my car etc. It has a seat for when I have to stop and …

  • I wish I could give Trionic Trek 10 stars!…

    I was very impressed with the speedy delivery. It feels like it was custom-made just for me and the kitty has already claimed the front basket! It came with 2 carrying bags and the extras we bought were certainly worth the overall cost.

  • Richard…

    Thank you for sending the back cushion for my new Veloped. It fits perfectly between the brake levers and provides much-needed comfort when sitting on the lower back.

    At this early stage, I am thrilled with how my Veloped makes walking more access…
