The news chainguard for the kids bikes

made in Bielefeld from Hebie

for kids bikes

The patented and completely closed chainguard for children’s bikes not only enhances the appearance of the bike, but also has a superior function, sturdy construction and a streamlined design, making conventional chainguards look ordinary in comparison. Around 80 individual clips are drawn onto the chain. The chain is riveted and assembled as usual. Then the interior parts are threaded and connected without the need for tools. The clips for protection are moving with the chain.The CHAINLOOPER not only satisfies all statutory regulations relating to protecting children’s hands from the chain, but also offers excellent protection against dirt. The standard chain guard comes in red and black, however other colours can be requested on the order.


In the first model we developed, the inner parts are designed for chainwheels with 32 teeth at the front; a varying amount of clips are attached to the chain - developed for KMC S1 (former KMC Z410) - depending on the number of links of the chain. In addition we developed two other inner part configurations for 25 teeth and 28 teeth chainrings. These clips will be automatically mounted in our branch in Taiwan, allowing us to deliver prefabricated chains to our customers. When the customer is assembling his bikes in the factory, only the inner parts need to be threaded through without tools ("How to" video on youtube) – this saves time compared to the assembly of a conventional chain guard.

Please check the tension of the bike chain regularly. It is also very important to take care of the chain periodically and to clean it from dirt and dust.

After adjusting the tension of the chain according to the specification of the bike manufacturer, the horizontal movement of the CHAINLOOPER (the inner parts) has to be adjusted again. Please use the CHAINLOOPER instruction as guideline ("How to" video on Youtube). Disassembling the inner parts completely is not necassary for the adjusting. A relubrication of the chain can be done in assembled and adjusted state. Preferrably in the lower chain strand let the lubricant run into the gap between the inner part and the clips from above. After some turns of the chain wipe away the excessive lubricant with an absorbant cloth. Dirt and dust can be removed with a garden hose before the lubrication, if necessary also with a brush and/or compressed air.

A complete disassembling of the inner parts is only necessary when the dirt is really heavy. As long as the cleaning interval is not set too long the normal dirt can be removed without disassembling the inner parts. Afterwards please lubrify the chain again as described above.


Notice for end users:
We are very happy about the great interest in our Chainlooper. But we have to inform you that the Chainlooper is NOT available as after-market equipment because the Chainlooper requires specific technical conditions. The Chainlooper is ONLY available as original equipment on the products where it is directly assembled by the manufacturer. Thank you for your understanding!
