Out of sight gears. For out of this world fun.

The woom ORIGINAL 3 AUTOMAGIC is a superlight 16" children's bike with an automatic 2-speed gear hub and numerous safety features. The gears are housed and sealed inside the hub on the rear wheel, which means they are protected from rain, snow, dirt and other external forces. Thanks to the upper-only, one-winged design of the chainguard, there's easy access to service the chain.

The woom bike with AUTOMAGIC gearing is suitable for children aged between 4 and 6 years old, or who fall into the height range of 105 to 120 cm. It is particularly well suited for children who are competent bike riders and ready to adventure further on two wheels or join the family on bigger bike rides. 

This model is also aimed at children who regularly cycle in hilly or windy areas. Having two gears as opposed to riding a single-speed bike tends to be a big advantage on light to moderate climbs or when riding into a headwind.

Compared to the standard woom ORIGINAL 3 (without automatic shifting), the first gear of the woom ORIGINAL 3 AUTOMAGIC is 17% lower while the second gear is 14% higher than the single-speed gearing.

The woom ORIGINAL 3 AUTOMAGIC has two gears. The internally geared hub automatically shifts between the two gears when the rider reaches 11 km/h. It will either shift up or down, depending on whether your child is speeding up or slowing down.

The woom ORIGINAL 3 AUTOMAGIC features a special rear hub designed by industry specialists Sturmey-Archer. The gearing is housed and sealed inside the hub and shifts automatically from the first to the second gear when the bike reaches 11 km/h. The automatic shifting, which is not visible from the outside, is caused by centrifugal forces.

Once the pace drops below 11 km/h, the automatic hub shifts back down to the first gear automatically. All the shifting takes place internally – there is no trigger shifter or gear cables. 

For kids who are already competent cyclists and often out and about on their bikes, having automatic 2-speed shifting will increase the scope for fun adventures. 

As it shifts automatically, young riders are free to concentrate on the ride rather than the complexities of changing gear manually, which can be a challenge too far at that age. 

A further benefit of this sort of gearing is that the action takes place inside the rear hub, resulting in a system that’s extremely reliable and low-maintenance. Compared to a conventional chain transmission, these gears are much better protected against impacts, weather conditions and dirt. This is especially beneficial for young riders, who may not always show their bike the necessary level of care.
