The sporty...The CRUSADER® 20-6 Alu

The PUKY® CRUSADER® 20-6 ALU is the ideal bike for sporty boys from 6 years of age.
PUKY® gives the lightweight aluminium frame of the CRUSADER® 20-6 ALU a sporty Shimano 1x6 derailleur. The finer gradation and lower loss of power compared to a 3-speed hub gear are ideal for young racers who still want to be safe on the road. With this circuit, the LED lighting system with parking light function and Shimano hub dynamo, the sturdy luggage carrier and the durable plastic mudguards, the PUKY® CRUSADER® 20-6 ALU is also well equipped for longer tours. PUKY®-typical are the many special safety features such as the edge protection on the mudguards, the safety handlebar grips and the safety bell, which cannot be opened and thus cannot release sharp edges. The PUKY® CRUSADER® 20-6 ALU is available in blue.

PUKY® road bikes have a well-thought-out frame geometry with a modern look. Although this is based on the trends that adults appreciate, it guarantees that children's requirements are taken into account in an optimum fashion. They have a very large adjustment range of saddle and handlebars, which guarantees a long service life without compromising the optimum controllability of the vehicle. All PUKY® bicycles are equipped in accordance with the German Road Traffic Licensing Regulations (StVZO) and may therefore be used on public roads.


Suitable for children from 6 years.

True size Size calculator

Step height

Basically we offer you three possibilities to determine the size of PUKY vehicles. We always recommend the inner leg length as the most reliable indication. How to determine this can be found here (How to find the right vehicle size). Alternatively, you can also use the height or age of the child as a guide.

Die Kinder finden im Nichts das Gesamte, die Erwachsenen im Gesamten das Nichts.

Giacomo Graf Leopardi (1798 - 1837)

Lightweight aluminium frame

Aluminium has long been used as a frame material for bicycles. Lightweight, rugged and rustproof - three major advantages that distinguish aluminium over steel. All of our ZL children's bike models have a noble aluminium frame.

Shimano 6-speed derailleur system

Chain shifts run very easily, as they absorb almost no drive energy compared to hub gears. The range between the gears and the transmission bandwidth is also better with 6 gears. It is easier for the driver to find the right gear, especially when the track has a few meters of altitude difference to offer. The built-in 1x6 drive dispenses with a front derailleur in order to simplify operation. Thus it represents the ideal entry into the world of derailleur gears. The system weight of a derailleur is also significantly lower than that of hub gears. So it pushes the weight under the magic 12 kilo limit.

Hollow chamber alloy rims

In order to allow higher rider weights with larger wheel diameters, we equip our bicycles with hollow-chamber rims. This design achieves an optimal STW (Stiffness to Weight) value. For example, the higher rider weights in larger children and adolescents are no problem.

Swallow tyres with reflective stripes

The high-quality dovetail tyres ensure low wear, good puncture resistance and perfect grip. The reflective strip replaces rickety spoke reflectors. The reflector is extremely bright, complies with the traffic regulations and cannot fall off. Safety first!

High-quality, child-friendly lighting system

The high-quality Shimano hub dynamo feeds an LED headlamp with on/off automatic. This prevents children from forgetting to turn on the lights in time. The new LED 1.5 volt technology reduces the weight of the hub dynamo considerably, increases the service life and makes it much easier to run under load without losing light output.

Exchangeable derailleur hanger

Especially with children's bikes you have to expect rough handling. In the case of derailleur gears, there is a risk that the rear derailleur's suspension will bend or even break off when a branch of the derailleur reaches the rear wheel. To avoid total damage, we equip our sprocket wheels with exchangeable derailleur eyes. If this should bend or break off, it is simply unscrewed as the intended breaking point between the rear derailleur and the frame and exchanged for a new one.
