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

  • Trionic Walker 14er…

    The Walker delivers what the advertising promises.…

  • Great product…

    I have the Walker 14er and love it for walking the dog as it goes anywhere. Bought this one to use when I go out shopping, etc. and am so pleased with it as I feel much safer when I use it. I do find it a little bit heavy but thoroughly recommend it…

  • Trionic Walker, a great device!!!…

    Just a great device, the 'Trionic Walker', which I ordered the end of June 2015 in Uppsala. Two days later, the Walker was already there. Due to a herniated disc which I had suffered in a fall from a bicycle, walking was always more difficult because…

  • Veloped Sport 12"…

    I am extremely satisfied with my Veloped Sport 12er M navy blue / red / white. So far, I have only used it for walks in nature and therefore mostly in a moorland with many transverse, exposed tree roots and boggy, soft passages. My Veloped overcomes …

  • Trionic Veloped is an excellent walking aid…

    Trionic Veloped works well when you are walking along pavements when it is snowy, dry or wet. It's also a very good walking aid to be used in the forest when you are walking along paths or even in more difficult conditions. If you decide to buy Trion…

    Nice greetings,

  • Walker 9er…

    Bought for my Dad
    Very well made, easy to use.

    Add on weights on the rear maybe a good idea, sometimes too easy to move with brakes on.…

  • The best outdoor rollator on the market…

    The admittedly high expectations of the Veloped (see previous reviews) were easily fulfilled. No other rollator I know is as stable, safe and reliable as the Veloped and so qualified for use in the countryside, woods and forests.
    However, the high s…
