The Cubley 18 features a lightweight, size specific alloy frame and is driven by a size specific crank set to suit their little legs. It rolls on 20h wheels, has 18" Deli tyres and a cool junior specific saddle. The reach is also reduced with the use of a super light one-piece handlebar and stem. WEIGHT MATTERS The Cubley 18 only weighs 7.56kg making this one of lightest bikes in the world for it’s price point and specification! Less weight helps smaller riders start easier, accelerate faster and handle the bike with more control.
Narrow handlebars with integrated
stem help reduce weight and improve
stiffness and safety by eliminating
any tightening bolts. Our handlebar
width is based on the typical shoulder
width of the rider and the stem length
is shorter, helping to reduce reach.
Crank length and Q-factor
(distance between the 2 cranks)
are 2 measurements which
are very difficult to get right.
With the help of many young
test riders, we find the
perfect balance!
Forme frames are made from
narrow, lightweight aluminium
tubing with a low step over. A
compact frame ensures the rider
can ride with the largest wheel
possible for their size and this
help young riders to ride over
much tougher terrain.
The Cubley saddle is sized for
smaller riders with length and
width optimized, ensuring the
rider position is correct for
both comfort and reach.
We had a “no-shortcuts” policy
when developing our Cubley range.
For example the headset (the part
which joins the fork to the frame) is
fully internal and hidden to provide a
longer-lasting bike to ride in
British conditions.
The weight of all wheel
components are considered to
keep them as light as possible
which helps to improve steering,
and acceleration. Also equipped
with great all weather Deli
18" tyres which ensure
maximum grip and stability
for cornering.
