Jawaban jujur untuk pertanyaan “seberapa besar kemungkinan seorang pesepeda dewasa AS mengalami cedera dalam kecelakaan akibat gangguan ponsel sepanjang hidupnya” adalah tidak ada yang tahu, dan kesenjangan ini bersifat struktural, bukan sementara. Sistem Pelaporan Analisis Kematian NHTSA mencatat pengemudi yang teralihkan perhatiannya yang menabrak pesepeda tetapi tidak mencatat penggunaan ponsel oleh pesepeda itu sendiri pada saat kecelakaan. Sistem Pengawasan Cedera Elektronik Nasional CDC mencatat sekitar 596.972 kunjungan unit gawat darurat untuk cedera otak traumatis terkait sepeda antara 2009 dan 2018, tetapi laporan MMWR 2021 secara langsung menyatakan bahwa “deskripsi naratif NEISS-AIP tidak memberikan informasi terperinci atau konsisten tentang… keadaan cedera”. Estimasi risiko kecelakaan yang ditinjau sejawat terkuat berasal dari Belanda — Goldenbeld dkk. 2012 menemukan bahwa peluang kecelakaan yang dilaporkan sendiri sekitar 1,6–1,8 kali lebih tinggi pada pesepeda remaja dan dewasa muda Belanda yang menggunakan perangkat elektronik portabel setiap perjalanan dibandingkan dengan yang tidak pernah menggunakannya, tanpa efek signifikan yang terdeteksi pada pesepeda yang lebih tua. Tinjauan sistematis Stavrinos dkk. 2017 tentang teknologi seluler dan risiko kecelakaan mengidentifikasi secara global hanya satu studi bersepeda yang memenuhi kriteria inklusi dan mengeluarkannya dari meta-analisis. Tidak ada ukuran efek agregat untuk dijadikan rujukan.
Apa yang ditetapkan literatur secara kualitatif adalah konsisten. Studi de Waard dkk. 2010 di Groningen menunjukkan bahwa berbicara di telepon saat bersepeda mempersempit penglihatan perifer, menurunkan kecepatan, dan meningkatkan beban dan risiko yang dirasakan, sementara mengirim pesan teks menghasilkan penurunan kinerja terbesar dari semua kondisi gangguan yang diuji — pergeseran posisi lateral, waktu reaksi yang lebih lama, dan frekuensi pandangan yang berkurang ke lalu lintas sekitarnya. Studi observasional Wolfe dkk. 2016 di Boston menemukan bahwa 31,2% pesepeda di empat persimpangan dengan lalu lintas tinggi teralihkan perhatiannya pada saat pengamatan, kira-kira terbagi antara gangguan pendengaran (17,7%, headphone dan earbud) dan gangguan visual atau taktil (13,5%, ponsel atau benda lain di tangan). Perilaku ini meluas, dan dampaknya terhadap input yang digunakan pesepeda untuk tetap tegak dan menghindari tabrakan adalah nyata.
Apa yang tidak ditetapkan literatur, dan mungkin tidak dapat dari data AS yang tersedia saat ini, adalah satu probabilitas seumur hidup. Bahkan setelah Belanda melarang penggunaan ponsel genggam saat bersepeda pada Juli 2019, evaluasi akademis dari larangan tersebut menyimpulkan bahwa tidak ada angka pasti untuk berapa banyak kecelakaan yang disebabkan oleh penggunaan ponsel saat bersepeda. Bukti Belanda adalah yang terdekat dengan jawaban kuantitatif yang dimiliki dunia, dan ia hidup di tingkat rasio peluang yang dilaporkan sendiri dalam subkelompok, bukan insidensi per pesepeda-tahun — dan pesepeda Belanda mengayuh di infrastruktur yang terlindungi dengan pangsa perjalanan populasi dua puluh hingga tiga puluh kali lebih tinggi daripada pesepeda AS, yang membuat transfer langsung apa pun mencurigakan. Kesimpulan jujur untuk pembaca bersifat kualitatif. Gangguan memperburuk kinerja bersepeda, mengirim pesan teks lebih buruk daripada menelepon, efeknya terkonsentrasi pada pesepeda yang lebih muda, dan konsekuensinya berkombinasi dengan lingkungan jalan — jalan arteri yang sama di mana sekitar dua pertiga kematian pesepeda AS sudah terjadi. Situs ini memperlakukan “kami sudah melihat dan bukti tidak mendukung sebuah angka” sebagai keadaan yang sah daripada kesenjangan untuk ditutup-tutupi, dan ini adalah salah satu entri tersebut.
Fakta terkait
Tidak ada probabilitas kecelakaan per pesepeda yang sahih saat terganggu ponsel. Arahnya jelas dari bukti — penggunaan ponsel menaikkan risiko kecelakaan — tetapi tidak ada penyebut AS yang andal untuk mengubahnya menjadi angka seumur hidup.

[1] Ergonomics (Taylor & Francis), via PubMed — Mobile phone use while cycling: incidence and effects on behaviour and safety Terverifikasi
Mobile phone use while cycling: incidence and effects on behaviour and safety- Statistik
In Groningen, NL, 2.2% of observed cyclists were talking on a phone and 0.6% were texting or dialling; only 0.5% of accident-involved cyclists reported phone use at the time of the crash- Kutipan
“"In Groningen 2.2% of cyclists were observed talking on their phone and 0.6% were text messaging or entering a phone number. In study 2, accident-involved cyclists responded to a questionnaire. Only 0.5% stated that they were using their phone at the time of the accident… Telephoning coincided with reduced speed, reduced peripheral vision performance and increased risk and mental effort ratings. Text messaging had the largest negative impact on cycling performance. Higher mental workload and lower speed may account for the relatively low number of people calling involved in accidents." ”

- de Waard et al. 2010 is the foundational observational study on cyclist mobile phone prevalence in the Netherlands. It is cited here for two reasons: (1) it establishes that the behavioural effect of phone use on cycling performance is real and measurable (peripheral vision narrows, speed drops, perceived risk rises), and (2) the 0.5% self-report among crash-involved cyclists is not a crash-risk rate — it is a snapshot of what crashed cyclists recall doing, on a non-representative sample, in the Netherlands. Even if taken at face value, it cannot be converted to a US per-crash or per-cyclist-year probability because the denominator (total cycling-phone-use exposure-hours) is not measured. No conversion to native or normalized US-adult lifetime probability is performed.

The use and risk of portable electronic devices while cycling among different age groups- Statistik
Self-reported crash odds were ~1.6× higher for Dutch teen cyclists and ~1.8× higher for young adult cyclists who used portable electronic devices on every trip vs cyclists who never used them; no significant effect detected for middle-aged or older cyclists- Kutipan
“"The odds of being involved in a bicycle crash are higher for teen cyclists (factor 1.6) and young adult cyclists (factor 1.8) who use electronic devices on every trip compared to cyclists who never use these devices. For middle-aged and older adult cyclists, the use of portable electronic devices was not a significant predictor of bicycle crashes, but frequency of cycling in demanding traffic situations was." ”

- Goldenbeld et al. 2012 is the strongest peer-reviewed estimate of crash-risk elevation from cyclist device use. The reported odds ratios (1.6 and 1.8) are self-reported, age-stratified, and Dutch — they describe relative risk between "every trip" and "never" device users in the same age cohort, not absolute probability per trip or per year. The effect disappears in older cohorts, suggesting either behavioural compensation or selection. Multiplying any baseline US cyclist crash probability by ~1.7 would be inappropriate because (a) the underlying US baseline for distraction-attributable crashes does not exist, (b) Dutch cyclists ride on protected infrastructure that US cyclists do not, and (c) "every trip" device use is a behavioural extreme, not the modal phone-using cyclist. The OR is cited as qualitative direction evidence (distraction increases crashes for younger cyclists) without a quantitative US transfer.

Distracted biking: an observational study- Statistik
Of 1,974 cyclists observed at 4 Boston intersections in summer 2016, 31.2% were distracted; 17.7% by auditory devices (headphones/earbuds) and 13.5% by visual/tactile devices (phone or object in hand)- Kutipan
“"Of the 1,974 bicyclists observed, 615 (31.2%) were distracted. Auditory distractions, predominantly headphones or earbuds, accounted for 17.7%, and visual/tactile distractions, predominantly a phone or other object in the hand, accounted for 13.5%. Reduced attention can place bicyclists and other road users at greater risk of sustaining an injury." ”

- Wolfe et al. 2016 (observations summer 2015, published 2016) is the best-available US observational prevalence study for cyclist distraction. It establishes that distraction is common (≈1 in 3 observed cyclists at Boston intersections) but does not link observed distraction to crash outcomes — there is no denominator-matched crash count for the same population. The study is cited as the US exposure-prevalence anchor that demonstrates the behaviour is widespread, while explicitly not supplying a crash-risk number. No native or normalized probability is derived.

An estimated 596,972 ED visits for bicycle-related TBIs occurred in the US during 2009–2018; the surveillance system does not record cyclist phone use, helmet use, or injury circumstances consistently- Kutipan
“"An estimated 596,972 ED visits for bicycle-related TBIs occurred in the United States during this study period (2009–2018)… NEISS-AIP narrative descriptions do not provide detailed or consistent information about helmet use, injury circumstances (e.g., whether the injury occurred on a road or bicycle path), or about a person's level of exposure." ”

- Sarmiento et al. 2021 (CDC MMWR) is the primary US bicycle-injury surveillance source. It documents that ED visits for bicycle-related TBI are common (≈60,000/year averaged over 2009–2018) but explicitly states that the surveillance instrument does not capture the circumstances that would let an analyst identify which crashes involved cyclist phone use. This source is cited as documentation of the data gap that prevents a US cyclist-phone-distraction injury rate from being estimated — the numerator data does not exist, regardless of what denominator one might assume.

- Stavrinos et al. 2017 is the closest available systematic review on mobile technology and crash risk that includes cycling as a category. The reviewers identified only one eligible cycling study (Kircher et al. 2015, an experimental study of behavioural compensation, not crash incidence), which they then excluded from quantitative synthesis. This is the strongest available evidence that no defensible pooled odds ratio exists for phone-while-cycling crash risk in the published literature. The source is cited as direct documentation of the evidence-base gap that justifies no_reliable_estimate=true.
