While that sounds reasonable, the specifics include bikes that few cyclists would define as “oversized.”<\/p>\n
Also from Caltrain bike rules<\/a>: [emphasis added]<\/p>\n What Makes a Bike Oversized?<\/p>\n Some bikes take up more space than the racks are designed for, including:\u00a0<\/p>\n \u2022 Wide or extra\u2011fat tires\u00a0(more than 3 inches wide)\u00a0 As one cyclist who uses Caltrain put it on Facebook<\/a>: “wtf? and no panniers?? It’s a commuter train.”<\/p>\n It also means that many families with small children will be unable to use Caltrain if their trips require a bike.<\/p>\n “As with the ever-bloating size of \u201ccars\u201d (SUVs & trucks) on our streets,\u00a0due to a similar trend of increasingly oversized\/overweight e-motos, e-bikes, and maybe a few larger\/wider ‘acoustic’ bikes and their attachments being brought aboard, there were increasing complaints\/issues raised by crews and\/or other bike car users about their disproportionate use of rack space & longer boarding times,” wrote Adrian Brandt, a Peninsula rail advocate and a San Mateo County representative on the Caltrain Citizens Advisory Committee (CAC), in an email to Streetsblog. “So staff advised the Bicycle and Active Transportation Advisory Committee and the CAC that they were working on a revised or tightened bike carriage policy to address the issue.” They didn’t provide the details, however, said Brandt.<\/p>\n “While crowded bike trains have been an issue as Caltrain has increased its ridership, the core problem is that they haven’t allotted enough space on their updated fleet of trains to accommodate an appropriate volume of people riding bikes,” wrote the San Francisco Bicycle Coalition’s Christopher White. “Many cargo bikes are under six feet in length, so inconsistently banning cargo bikes even if they\u2019d fit within the limits is confusing and will cause riders to unnecessarily avoid Caltrain.”<\/p>\n “An outright ban on family bikes is too extreme.\u00a0While commute period trains can get crowded, mid-day and weekend trains are not,” wrote Shirley Johnson, who helped found the advocacy group BIKES ONBoard. “Instead of a ban, it would be better to ask people with larger bicycles to use their discretion and travel off-peak whenever possible.\u00a0Caltrain needs to remember that every passenger with a bicycle is a paying customer.”<\/p>\n Johnson, along with White and others, stressed that Caltrain itself is responsible for the overcrowding these new rules are trying to address. Back in pre-COVID 2019, bicycle advocates begged Caltrain to have three bike cars per electric train (instead of two)<\/a>.<\/p>\n “As was long-known\/established, with the new electric trains’ bike space dropped 10 percent from 40 per bike car on the old\/retired gallery cars to 36 per bike car (or from 80 down to 72 per train),” said Brandt.<\/p>\n “Today, we see riders with bikes turned away because the cars are at capacity. Now, they are trying to address that with more restrictive rules on what types of bikes are allowed on board,” wrote the Silicon Valley Bicycle Coalition’s Amy Thomson. “Banning large bikes is likely to\u00a0shift bike\u00a0+ transit trips to a car, which we absolutely cannot sustain or afford as a region.\u00a0More than 20 percent<\/a>\u00a0of Caltrain riders arrive or leave the station by bike.”<\/p>\n Streetsblog reached out to Caltrain and will update this post.<\/p>\n","protected":false},"excerpt":{"rendered":"Advocates were outraged to learn this week that Caltrain will start banning cargo bikes and any bike that…\n","protected":false},"author":2,"featured_media":204729,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[30],"tags":[101,103,102,104,106,105],"class_list":{"0":"post-204728","1":"post","2":"type-post","3":"status-publish","4":"format-standard","5":"has-post-thumbnail","7":"category-san-francisco","8":"tag-san-francisco","9":"tag-san-francisco-headlines","10":"tag-san-francisco-news","11":"tag-sf","12":"tag-sf-headlines","13":"tag-sf-news"},"_links":{"self":[{"href":"https:\/\/www.newsbeep.com\/us-ca\/wp-json\/wp\/v2\/posts\/204728","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.newsbeep.com\/us-ca\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.newsbeep.com\/us-ca\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/us-ca\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/us-ca\/wp-json\/wp\/v2\/comments?post=204728"}],"version-history":[{"count":0,"href":"https:\/\/www.newsbeep.com\/us-ca\/wp-json\/wp\/v2\/posts\/204728\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/us-ca\/wp-json\/wp\/v2\/media\/204729"}],"wp:attachment":[{"href":"https:\/\/www.newsbeep.com\/us-ca\/wp-json\/wp\/v2\/media?parent=204728"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.newsbeep.com\/us-ca\/wp-json\/wp\/v2\/categories?post=204728"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.newsbeep.com\/us-ca\/wp-json\/wp\/v2\/tags?post=204728"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}![\"\"](\"https:\/\/www.newsbeep.com\/us-ca\/wp-content\/uploads\/2026\/03\/Screenshot-from-2026-03-03-12-00-42.png\")

When Caltrain transitioned from diesel to electric, it reduced the number of bike cars. Now they’re paying the price. Photo: Caltrain<\/p>\n
