Smart4u SH50 Smart Urban Helmet combines everyday head protection with an integrated seven-LED rear warning light for cycling and scooter commutes.
Automatic brake warning: the rear LEDs brighten for approximately 1–2 seconds when the helmet detects a clear deceleration. Three lighting modes and automatic light sensing support visibility in changing conditions.
Comfort and construction: the reviewed product images show a PC outer shell, honeycomb EPS cushioning, 12 ventilation openings and an approximate weight of 370 g. The light uses magnetic USB charging and the helmet is rated IPX4 for splash resistance.
Before riding: choose White, Black or Pink, adjust the retention system for a secure fit, fasten the chin strap and replace the helmet after a significant impact or visible damage.
