Test Pyro Twenty: The children's bike brand from Technibike delivers a convincing 20-inch bike that dignifiedly represents the type of modern, sporty all-rounder. On the positive side: different frame sizes and touch-up pencils.
The Technibike company from Daun in the beautiful Eifel region is best known for e-bikes; under the brand name Pyro, the company also sells children's and youth bikes from 12-inch wheels to 27,5 hardtails with air suspension forks. What all bikes have in common is their sporty orientation - you won't find any school bikes with lights, mudguards and carriers at Pyro. The range of accessories includes short sports mudguards and side stands of various lengths. It's pretty clever that you can find touch-up pencils in the four colors of the collection on the homepage. In this way, scratches and kitsch can be repaired quickly and unobtrusively.
It is also interesting that Pyro offers all models from 16 inches in two frame sizes. The smaller version is designed for a 3 to 5 cm smaller inner leg length. The size chart on the website makes it fairly easy to determine the right size. In the smaller versions, the standover height has also been adjusted; the top tube has a clearly visible kink.
In size L, it is also easy to ride for smaller ones
The fact that the Pyro Twenty L should actually only be ridden from a height of 114 cm doesn't bother our test pilot Alois - with his 107 cm he gets along well with the light bike; he would probably quickly outgrow the smaller version. Oddly enough, the larger frame has a 5mm shorter head tube but is fitted with a longer fork. It might be possible to replace the rigid fork with a short-travel suspension fork without significantly changing the frame geometry. But that doesn't necessarily make sense in this category.

Simple and solidly equipped
Pyro equips the little racer with simple but useful components typical of the genre. Mechanical rim brakes with children's brake levers, an eight-speed shifter with a twist grip - experience has shown that the youngsters get along well with them. With an 11-32 cassette and 32-tooth chainring, the gear ratio is child-friendly and short enough for mountain rides; the screwed chain guard rings are good. Frame and fork allow the installation of fenders; you can also attach a carrier at the back.
The manufacturer specifies 47 mm wide Schwalbe tires that are not too heavily profiled; so the bike should be able to cope well on pretty much any surface. The slightly larger tire volume gives you the option of lowering the pressure off-road, which improves traction and comfort.
Weighing in at just over eight pounds (including pedals), the Pyro 20 is one of the lighter 20-inch models; its price of 569 euros is slightly higher than what other providers charge for comparable models. It should be noted that Pyro states a permissible total weight of 40 kilos - the driver may therefore weigh a maximum of 32 kilos. Children who are that heavy are likely to be too big for a 20-inch bike anyway.
