The Hase Trix is ideal for larger kids with special needs – it’s the big brother to the Trets, a bit smaller than a Kettwiesel, but will fit anyone from 4’1″ to 6’3″ so it will still be usable into adulthood.
The Trix comes with disc brakes and 8-speed hub gearing, mudguards and lighting. Loads of options are also available to modify it if needed.
For all the options, have a look at the Configurator on Hase’s site.
