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

  • A joy to use…

    I bought a walker last year (Not Trionic) in the hope that I could restore some of the strength in my legs. It could not cope with Birmingham pavements! Four small wheels do not cope with tree roots, potholes and significant camber. Then I found Trio…

  • Surprising good…

    This holder was ordered at the same time I ordered the Veloped and came already attached to the frame. I haven't actually used it for its intended purpose of housing a walking stick but found it has a double purpose and currently holds my dogs retrac…

  • Simply AMAZING…

    I ordered it last weekend, and the Veloped arrived on Wednesday. It's very easy to assemble. And most importantly, it's a joy to ride over rough terrain. My husband and I immediately chose a challenging route: cobblestones, grass, fields, roots. No p…

  • FREEDOM…

    I love my Trionic Rollator Walker. The solid wheels and wide base allow me to walk over rough basements and bumps as if they were smooth as glass. I also appreciate how stable the walker is, because that makes me feel safe. I don't have any problems …
