2018 Ridgeback Dimension 20


Ridgeback Dimension 20"
Suitable for boys or girls, the Dimension is based on a very lightweight aluminium frame. It also comes fitted with quality lightweight aluminium parts - such as the seatpost, handlebars, handlebar stem and cranks. It has 20 x 1.5" tyres - which also helps keep the weight down. They're narrower than on a mountain bike - for speed on road; but but wide enough for a bit of comfort off road. It's sensibly specified with 7 speed gears - as much as they'll ever need. It comes in a range of three colours. Suitable for children from 5-7 years old.
