Hand signals work fine at 12 mph on a pedal bike. At 28 mph on a Class 3 e-bike, taking a hand off the bars in traffic is a worse idea — and drivers increasingly don’t know what hand signals mean anyway. Smart helmets with integrated turn signals solve this: tap a handlebar remote, and amber LEDs on the back of your helmet tell traffic where you’re going.
But here’s the thing most roundups won’t tell you: at e-bike speeds, the turn signals are the second most important spec. The first is the impact certification. Standard CPSC/EN1078 tests simulate roughly 12 mph impacts; NTA-8776 tests at the higher energies of speed-pedelec use. Only one helmet in this roundup publishes NTA-8776 — and that’s our top pick: the Lumos Ultra E-Bike at around $200.
How we picked
- Certifications first: NTA-8776 (e-bike crash rating), CPSC, and CE EN1078 verified against manufacturer and retailer listings — not marketing copy.
- Signal activation method compared: handlebar remote vs. gesture vs. automatic, and whether the remote is included or a separate purchase.
- Weight and battery specs side by side: smart helmets run heavy; we show the numbers so you know the tradeoff.
- No fake hands-on testing: we didn’t crash-test anything. We compared published specs and certifications, and we flag every claim we couldn’t verify. Our full methodology.
Our top pick: Lumos Ultra E-Bike
This is the only helmet here with verified NTA-8776 certification — the one rating actually designed for how fast e-bikes go — and it covers everything else too: turn signals via a wireless handlebar remote that’s included in the box (no separate purchase), automatic brake lights, CPSC plus CE EN1078 plus AS2063 plus ASTM F1447, IPX6 waterproofing, USB-C charging, and the largest battery in the roundup (1300 mAh). The standard Lumos Ultra is lighter and cheaper but lacks the e-bike impact rating; the Livalls are lighter still but can’t touch the certification story. For a site about e-bikes specifically, NTA-8776 is the decisive, verifiable differentiator.
- Certifications: NTA-8776, CPSC, CE EN1078, AS2063, ASTM F1447, IPX6
- Signals: wireless handlebar remote (included); auto brake lights; Apple Watch gesture control (beta)
- Battery: 1300 mAh Li-Po, 2–10 hours, 3 h charge, USB-C
- Weight: 490 g (530 g with MIPS)
- Price band: $200 ($230 with MIPS)
The tradeoff is weight: 490–530 g is the heaviest helmet here, the price of the e-bike rating. Riders sensitive to neck fatigue should know that going in.

Lumos Ultra (standard) — lighter and cheaper, same ecosystem
Same signal platform as the E-Bike variant — 30 front LEDs, 64 rear, app customization, team sync — in a lighter, cheaper package ($140, or $170 with MIPS). The catches: no NTA-8776 rating, so it’s best for urban e-bike riding under 20 mph rather than Class 3 speeds, and the turn-signal remote is sold separately, so confirm what’s in the box before you buy. If you ride a Class 1/2 bike and want the Lumos ecosystem without the weight penalty, this is the rational pick.
- Certifications: CPSC, CE EN1078 (NTA-8776 not claimed)
- Signals: rear turn signals via Lumos Remote (sold separately — verify)
- Battery: 1100 mAh, 4–10 hours, USB-C
- Weight: 370 g (409 g MIPS, M-L)
- Sizes: S (51–55 cm), M-L (54–61 cm), XL (61–65 cm)
- Price band: $140 ($170 MIPS)
Livall BH60SE Neo — signals plus audio in one helmet
The value play with a twist: turn signals via handlebar remote, plus built-in Bluetooth speakers and mic for music, calls, and navigation audio, plus fall detection with SOS alerts through the Livall app. At $120–140 it’s the cheapest way to get signals and genuinely useful extras. Certifications (CPSC 1203, EN1078) are verified via retailer spec sheets — but NTA-8776 is not claimed, so keep it to sub-20-mph riding. One real-world note: the speakers sit over your ears, so check your local laws on headphones while cycling before you buy for the audio.
- Certifications: CPSC 1203, EN1078 (NTA-8776 not claimed)
- Signals: wireless handlebar remote; auto on/off when worn
- Battery: 600 mAh, ~10 h lighting (3–6 h with music), magnetic USB
- Weight: 320–340 g
- Extras: Bluetooth 5.0 speakers, fall detection + SOS, voice command
- Price band: $120–140
Livall EVO21 — the lightweight value pick, with a certification caveat
The lightest-feeling smart helmet here (around 330–350 g), with 360° LED coverage, remote-activated turn signals, automatic brake warning light, and fall detection — all for $110–150 on Amazon. Here’s the honest downgrade: Livall’s marketing mentions CPSC/CE, but we could not verify those certifications in the retailer spec sheets we checked. Until that’s confirmed, treat the safety rating as unproven and buy it for the signals and value, not for certified protection. Also note: no speakers or intercom on this model, which Livall states explicitly.
- Certifications: CPSC/CE claimed in marketing — unverified in retailer spec sheets
- Signals: wireless handlebar remote; automatic brake warning light
- Battery: exact capacity unverified; magnetic USB charging included
- Weight: ~330–350 g
- Price band: $110–150
Sena R2X — not a turn-signal helmet (the honest alternative)
We’re including this precisely so you don’t buy it by mistake. The Sena R2/R2X shows up in “smart helmet” searches, but per Sena’s own published specs it has an integrated LED taillight — not turn signals. Listing it in a turn-signal roundup without saying so would mislead you. What it does offer is the best helmet-to-helmet communication here: Mesh Intercom for virtually unlimited riders up to 900 m, Alexa built-in, Bluetooth 5.1, and 8–12 hours of talk time. If you ride in groups and care more about talking to your riding partners than signaling to cars, buy it for the intercom — with the caveat stated plainly.
- Certifications: CE EN 1078, CPSC 1203 (NTA-8776 not claimed)
- Signals: none — taillight only (on/off/blink)
- Comms: Mesh Intercom, Alexa, Bluetooth 5.1
- Weight: 420 g (M)
- Price band: $150–230

What to watch out for
- NTA-8776 is the spec that matters at 28 mph. If you ride a Class 3 e-bike, a standard CPSC-only helmet is certified for impacts well below your cruising speed. The Lumos Ultra E-Bike is the only lid here with the e-bike rating.
- Nobody publishes turn-signal viewing angles. Unlike tail lights (Garmin publishes 220° for the Varia), no smart-helmet maker publishes the viewing angle of its signal LEDs. Treat “visible from behind and the side” as marketing until someone tests it properly.
- Remotes are Bluetooth — check what’s in the box. The Lumos E-Bike includes the remote; the standard Ultra’s remote is a separate purchase. Livall includes remotes. Confirm before you buy, or your “turn signal helmet” has no way to signal.
- Weight is real. Smart helmets run 320–530 g versus ~250–300 g for a plain road helmet. The NTA-8776 rating costs grams; that’s physics, not a flaw — but neck-fatigue-sensitive riders should factor it in.
- Speaker laws vary. The Livall BH60SE Neo’s ear-covering speakers may run afoul of local cycling headphone laws. Check yours.
FAQ
Do I need an NTA-8776 helmet for my e-bike?
If your e-bike assists to 28 mph (Class 3), yes — that’s exactly what the rating is for. Standard CPSC/EN1078 tests simulate lower-speed impacts. For Class 1/2 bikes capped at 20 mph, a well-fitting CPSC helmet is the normal, reasonable choice.
How do helmet turn signals actually work?
A small wireless remote mounts on your handlebar. Tap left or right and amber LEDs on the helmet’s rear flash on that side; most of these helmets also flash all rear LEDs under braking automatically. No wiring, no installation beyond pairing the remote.
Are smart helmets with turn signals legal everywhere?
The helmets themselves are legal wherever bike helmets are legal, provided they carry the required local certification (CPSC in the US). The turn signals are a supplement to — not a replacement for — knowing your local signaling expectations. And as noted above, built-in speakers may be restricted in some places.
How long does the battery last on a smart helmet?
It varies a lot by settings: 2–10 hours on the Lumos Ultra E-Bike depending on brightness and patterns, ~10 hours of lighting on the Livall BH60SE Neo (dropping to 3–6 with music playing). All of these charge over USB in about 3 hours. If you commute daily, get in the habit of charging with your lights.
Will drivers actually understand helmet turn signals?
Amber flashing lights on one side of a helmet read as a turn signal to most drivers — it’s the same visual language as a car’s indicators. They’re clearest from directly behind; side-angle visibility is the open question no manufacturer publishes data on.
Bottom line: at e-bike speeds, buy the certification first and the signals second — which is why the NTA-8776-rated Lumos Ultra E-Bike is our pick.
