TENWAYS EH20 Smart Helmet

TENWAYS EH20 Smart Helmet is a connected bike helmet built for everyday city riding — automatic LED lights front and rear, integrated turn signals, built-in speaker and voice control, all in a 420 g shell that passes both European (EN 1078) and US (CPSC 1203) safety standards.

Why it earns the upgrade

Most of the year in Iceland you're either riding in fading light or full dark. The EH20 turns its front and rear lights on automatically the moment the ambient light drops, and lets you signal left or right with a thumb-click on the remote — without ever taking a hand off the bar. The built-in speakers handle navigation, calls, and music without sealing you off from traffic.

Key features

• Auto-on LED lights — front and rear lights switch on automatically in low light
• Integrated turn signals — controlled from the handlebar remote, helmet button, or app
• Built-in speakers — calls, music, and navigation prompts without earbuds blocking road sound
• Voice assistant ready — hands-free control of phone and bike apps
• Bluetooth 5.1 — stable connection to phone and the TENWAYS app
• 950 mAh battery — full charge in about 2.5 hours, USB-C
• IPX4 water resistance — built for everyday rain; not for prolonged downpours
• EN 1078 + CPSC 1203 certified — passes both the European and US safety standards
• Weighs 420 g — comparable to a regular high-end helmet, despite the electronics
• Two colours — Slate Grey, Floral Silver

How you control it

Three options, all working in parallel:

• Handlebar remote — clip onto the bar, thumb-click left/right for indicators, single button for music or call answer
