Despite newly introduced regulations, specifically, speed limits and sidewalk driving prohibitions, the number of accidents increases due to the challenges in enforcement. Therefore, a reliable method to detect safety-threatening illegal behaviors of e-scooters is essential to mitigate this growing problem. In this article, we propose SecureRide, a system that accurately detects illegal e-scooter behaviors, i.e., speeding violation and sidewalk riding, at runtime using only battery information, without the need for additional sensors. To this end, we first design a neural network-based illegal behavior predictor that takes sequences of three battery factors, i.e., voltage, current, and capacity, as inputs. The model architecture is optimized based on time constraints, target accuracy, and resource constraints of the target devices. Next, we devise a runtime detection strategy to achieve both high accuracy and low detection time. SecureRide operates in two modes with different predictors\u2013\n            <jats:italic toggle=\"yes\">lightweight-quick<\/jats:italic>\n            and\n            <jats:italic toggle=\"yes\">complex-accurate<\/jats:italic>\n            models\u2013depending on the driving situation, ensuring both high accuracy and low detection time. We extensively validate SecureRide based on actual driving experiments. Our results show that SecureRide detects illegal behaviors with an accuracy of up to 99.77% within 1.01 seconds.\n          <\/jats:p>","DOI":"10.1145\/3758095","type":"journal-article","created":{"date-parts":[[2025,8,2]],"date-time":"2025-08-02T11:18:12Z","timestamp":1754133492000},"page":"1-24","update-policy":"https:\/\/doi.org\/10.1145\/crossmark-policy","source":"Crossref","is-referenced-by-count":0,"title":["SecureRide: Detecting Safety-Threatening Behavior of E-Scooters Using Battery Information"],"prefix":"10.1145","volume":"24","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-5182-2667","authenticated-orcid":false,"given":"Jiwon","family":"Kim","sequence":"first","affiliation":[{"name":"Electrical Engineering, Uppsala University","place":["Uppsala, Sweden"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0009-0003-1398-8724","authenticated-orcid":false,"given":"Geon","family":"Kim","sequence":"additional","affiliation":[{"name":"Computer Science, Yonsei University","place":["Seoul, Korea (the Republic of)"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9035-2602","authenticated-orcid":false,"given":"Jeho","family":"Lee","sequence":"additional","affiliation":[{"name":"Yonsei University","place":["Seoul, Korea (the Republic of)"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2586-8573","authenticated-orcid":false,"given":"Thiemo","family":"Voigt","sequence":"additional","affiliation":[{"name":"Electrical Engineering, Uppsala University","place":["Uppsala, Sweden"]},{"name":"RISE Research Institutes of Sweden AB","place":["Uppsala, Sweden"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9060-5091","authenticated-orcid":false,"given":"Hojung","family":"Cha","sequence":"additional","affiliation":[{"name":"Yonsei University","place":["Seoul, Korea (the Republic of)"]}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"320","published-online":{"date-parts":[[2025,9,26]]},"reference":[{"key":"e_1_3_1_2_2","doi-asserted-by":"publisher","DOI":"10.1038\/s41598-024-69462-9"},{"key":"e_1_3_1_3_2","unstructured":"Arduino. 2025.
