The Trek Charge WaveCel is NTA-8776 certified in accordance with the Dutch standard. This standard applies to e-bikes with speeds of up to 45 km/h. The certification therefore makes the helmet a potential choice for commuters and everyday cyclists who ride fast e-bikes. The Virginia Tech Helmet Lab awarded the Charge WaveCel four stars. The independent testing programme assesses helmets based on their protective potential in the event of a fall. According to the organisation, higher ratings indicate a lower risk of concussion. Virginia Tech recommends helmets rated four stars or higher.

Conclusion

​With the Charge WaveCel, Trek is specifically targeting riders of fast e-bikes and commuters who value a high level of safety and suitability for everyday use. The NTA-8776 certification, the good rating in the Virginia Tech test and the standard rear light all point to a well-thought-out safety concept.

Trek Flare Light with magnetic attachment

Every Charge WaveCel comes with the Trek Flare Helmet Light. The rear light attaches magnetically to the helmet and can be removed for charging. The charging time is 90 minutes. The light is designed to make cyclists visible from a distance of up to 400 metres and offers four different flashing patterns for daytime use. The magnetic attachment allows for quick removal and attachment without the need for tools. The light is charged via USB-C.

Weight reduction and ventilation

The current version weighs 50 g less than the previous model. This represents a weight reduction of 13 per cent. Ventilation has been improved by 150 per cent, which should provide better cooling during hot rides. WaveCel technology forms the core of the protective structure. Trek combines this technology with the BOA Fit System, which allows for stepless size adjustment.

Everyday essentials

The Fidlock fastening is easy to open and close. The straps can be adjusted without any complicated mechanisms. An opening at the back serves as a helmet lock pass-through. This allows riders to secure the helmet using their bike lock. The BOA system sits at the back of the head and tightens an internal mesh that adapts to the shape of the head. Turning the dial increases or decreases the tension. The Trek Charge WaveCel is available from selected Trek dealers and online.
