Toronto Streetcar Tracks Cause One in Three Bike Crashes Downtown. Here's the Ebike Setup That Actually Helps.

Toronto Streetcar Tracks Cause One in Three Bike Crashes Downtown. Here's the Ebike Setup That Actually Helps. - Buzzify

Every cyclist who has ridden King Street in the rain knows the feeling. Your front wheel ticks into a rail flangeway, the bar yanks sideways, and you go down. The road is dry six inches to the left and dry six inches to the right. The 50 mm strip in the middle owned you.

This is not a small problem. A UBC and Toronto Metropolitan University study of 276 hospitalized cyclists in downtown Toronto found 87 of those crashes — almost exactly one in three — directly involved streetcar tracks. The flangeways did it. Cyclists swerved to avoid a door, a pedestrian, or a turning Uber, and the front tire dropped into the gap. Two thirds of those crashes happened away from intersections, on a clean stretch of road, in normal traffic. No collision required.

If you ride a Class 1 or Class 2 ebike anywhere south of Bloor and west of the Don, this is your single biggest crash risk. More than cars. More than dooring. More than potholes. And it has nothing to do with how good a cyclist you are.

Here is what the research actually says, and how the bike you ride changes the math.

Toronto's track network is bigger than you think

The TTC streetcar system runs roughly 290 km of in-street track across ten routes. The 501 Queen alone is the longest streetcar line in North America, running 25 km from Long Branch to Neville Park. Add the 504 King, 505 Dundas, 506 College, 509 Harbourfront, 510 Spadina, 511 Bathurst, 512 St. Clair, 503 Kingston Road, and 514 Cherry, and there's track stitched across nearly every east-west arterial below St. Clair and several north-south corridors. Roncesvalles, Broadview, Bathurst, Spadina, Cherry. The Eglinton Crosstown Line 5 opened February 8, 2026 and added its own at-grade running where it surfaces in the east end.

Then add the construction work the TTC has scheduled through 2026 to rebuild aging trackage on King, Queen, and College. Every torn-up corner is a temporary patch with a different rail height, a different gap profile, and sometimes a temporary asphalt fill that settles unevenly within weeks. The hazard is moving.

The flangeway itself is the killer. That's the slot beside the rail where the streetcar's wheel flange sits. Toronto's flangeways are about 50 mm wide. Drop a narrow tire into one at any angle other than perpendicular and your front wheel stops, your fork rotates, and you keep going forward without the bike.

What the research actually found

The Teschke et al. paper (BMC Public Health, 2016) is the study to know. It pulled 276 cyclists who'd ended up in a Toronto ED with a bike injury between 2008 and 2009. Of those, 139 crashed in areas with streetcar track. Eighty-seven crashes directly involved the track itself.

Three findings matter for anyone buying an ebike for Toronto:

Crossing angle is everything. When you cross a rail at 90°, the contact patch rolls across the gap cleanly. At 45° you're borderline. Below 45° you're playing the lottery. Sixty-seven percent of track crashes happened away from intersections — meaning a sudden swerve on a straight road, usually to avoid something else, dropped the cyclist below the safe angle window.

Tire width changes the odds. The 2016 paper noted that 54% of bikes commonly sold in Toronto came with tires narrower than the flangeway gap. Narrower than the slot, the tire drops in. Wider, it bridges. Tires under 30 mm (road, single-speed) are the worst. 33–37 mm (touring, urban hybrid) helps a little. 50 mm and above bridges most flangeways most of the time.

Painted bike lanes cut the odds 85%. Not because paint stops a tire from dropping. Because the lane removes the swerve. You're not weaving around a parked car or a delivery van; you're holding a straight line at a stable distance from the rail.

Women had double the odds of a track injury. The authors flagged this without a definitive explanation, but the leading theory is that a smaller average rider on a smaller frame with narrower factory tires is exposed to all three risk factors at once.

There is also a more recent number that puts the older study in perspective. An ICES analysis published in 2024 found more than 30,000 emergency department visits for cyclist injuries in Toronto between 2016 and 2021. Police data captured 2,362 — about 8% of the actual ED count. Eighty percent of hospital admissions for cycling injuries did not involve a motor vehicle. The streetcar track problem is much larger than the Vision Zero stats suggest.

Why ebikes are partly better, partly worse

The good news first. An ebike with a torque-sensor mid-drive holds a straighter line than a comparable acoustic bike. The motor smooths out your pedal stroke and reduces the small front-wheel wobble that gets a tire caught on a wet rail. The bike is heavier, so it tracks more stably through a partial flangeway hit at low speed. Most commuter ebikes ship with 50 mm or wider tires from the factory — Trek Allant+, Gazelle Ultimate C8+ HMB, Specialized Turbo Vado SL 2, Velotric Discover 3, Aventon Level 3 — because manufacturers know what real cities look like.

The bad news. An ebike at 25 km/h hits a flangeway with about 40% more kinetic energy than an acoustic bike at 21 km/h. A cargo ebike with a kid on the back is carrying a load that doesn't want to recover from a fork twist. And torque-sensor assist will hold its output through your panic input — if you swerve at the wrong angle, the motor will helpfully accelerate you into the rail.

The take: ebike geometry and weight make tracks more forgiving at slow speeds, less forgiving at speed, and roughly the same at panic-swerve moments.

The tire spec that actually matters

If you're shopping for a Toronto ebike specifically and streetcar tracks scare you (they should), filter on tire width first.

Under 40 mm: avoid for downtown. Pure road ebikes, the lightest fitness-class builds, some folding bikes with 20-inch wheels and 1.5-inch tires. Fine on the Martin Goodman Trail. Risky on King.

42–47 mm: acceptable with caution. Most lightweight commuter ebikes land here. Specialized Turbo Vado SL 2 ships with 38 mm but accepts up to 47 mm. Trek FX+ 2 Stagger and similar urban hybrids sit in this band. Workable in painted bike lanes, dicey in mixed traffic on Queen.

50–55 mm: the Toronto sweet spot. Trek Allant+ 7 and 8, Gazelle Ultimate C8+ HMB, Riese & Müller Charger4, Tern Quick Haul, most Velotric and Aventon commuters. Wide enough to bridge a 50 mm flangeway in most positions and orientations. Comfortable on the cobble-and-rail mix on King West.

60 mm and up: cargo and fat-tire territory. Tern GSD S10 Gen 3 (62 mm), Aventon Abound LR, Urban Arrow Family Next Pro, Riese & Müller Load 4. The tire is so much wider than the slot that even a marginal-angle crossing usually just thumps over. The trade is weight and a less responsive front end.

A note on tubeless. Tubeless setups with sealant let you run lower pressure, which gives a wider tire contact patch and even better track bridging. Most factory ebike wheels are tubeless-ready but ship with tubes. Worth the conversion if you ride downtown daily.

Tread doesn't matter much for tracks. A slick urban tire bridges a flangeway as well as a knobby. Casing strength matters more — a stiffer sidewall is harder to deflect into the gap.

The Toronto streetcar track survival guide

These six rules cover 95% of track encounters. None of them require special equipment.

1. Cross at 90°. Always. If you're about to ride down a track-running street, scan ahead. When you must cross from one side to the other, square up your bars, slow if needed, and roll across perpendicular. A two-second deceleration is cheaper than an ambulance.

2. Never ride between the rails on a downhill. Roncesvalles southbound, Bathurst from St. Clair down, Spadina from Bloor down. Gravity wants to pull your tire into the inside rail. Ride to the right of the curb-side rail or in the parking lane gap. If the lane is too narrow, take the full lane.

3. Wet rails are ice. Polished steel, wet, on a bike tire — there's no traction. Don't lean on them. Don't brake on them. Roll across them upright and unloaded. The first 10 minutes of a Toronto thunderstorm in July are the most dangerous riding conditions in the city. Worse than snow.

4. Don't get door-trapped into a swerve. The classic track crash is: car door opens, you flinch left, your tire drops in the rail beside you. The fix is not "be ready to swerve." The fix is to ride far enough from parked cars that you don't have to swerve. One metre minimum. That puts you on or past the curb-side rail, which means you should either be riding the full lane or in a separated lane. Half-measures kill people.

5. Treat construction zones like new hazards every time. TTC trackwork on King and Queen through 2026 means the rail profile changes from week to week. Temporary asphalt fills around new rails settle and pull away from the steel within a month, opening fresh flangeway-sized gaps. Look at the seam every time you ride a section under construction. Don't ride a familiar route on autopilot.

6. Slow down at intersections with curving tracks. Spadina at College. King at Roncesvalles. Queen at Broadway. The rails curve and the inside of the curve has a very acute crossing angle for anyone trying to cross the street. Brake before, not after. Cross perpendicular, even if it adds three seconds.

Where to actually ride

Toronto has spent the last decade building separated cycle tracks on exactly the corridors where streetcar tracks killed people. Use them.

Bloor cycle track (still under the Cycle Toronto v. Ontario injunction as of June 2026 — lanes remain in place pending the Court of Appeal decision). No streetcar trackage west of Yonge. Cleanest east-west option for the central city.

Adelaide and Richmond cycle tracks. No tracks at all. Use these instead of King or Queen whenever the destination allows.

Sherbourne and Wellesley. Track-free north-south spines downtown.

Martin Goodman Trail. Continuous, paved, track-free. The default for anyone going east-west along the waterfront. There is one painful exception: where the trail crosses the streetcar loop at Exhibition Place, the rails are at an awkward angle. Dismount or take a wide, perpendicular line.

West Toronto Railpath. The current 2.1 km section runs from Cariboo Avenue to Dundas West. No tracks, no cars, fast. The Phase 2 extension south to Liberty Village is under construction with completion projected for fall 2026.

The Don Valley network. Lower Don Trail reopened in spring 2026 after the 18-month Pottery Road–Queen Street rebuild. Track-free, fast, the spine of east-end commuting.

The corridors to avoid when wet: Roncesvalles southbound, Queen West between Bathurst and Spadina, King Street between Bathurst and Jarvis, Spadina south of Bloor, Broadview south of Danforth, Lakeshore Boulevard where the Long Branch loop meets the Humber, College west of Bay.

The honest opinion

Toronto's streetcar tracks have not been redesigned. They will not be redesigned. The flangeway dimension is fixed by the geometry of a low-floor streetcar wheel flange — you cannot make it narrower without derailing trains. The only inputs you control are the bike you ride, the route you pick, and the line you hold.

That makes the bike choice load-bearing. A 50 mm-tire torque-sensor commuter ebike is the right answer for almost every Toronto rider who spends time south of Bloor. Skinny-tire road ebikes belong on the Martin Goodman Trail. Fat-tire cargo ebikes belong wherever you need them, and they laugh at flangeways. The category to avoid is the cheap throttle ebike with 1.95-inch tires and no torque sensor — you get the worst of all worlds: width that doesn't bridge, motor input that doesn't smooth your stroke, and a chassis that flinches when you do.

If you're not sure which side of that line your bike sits on, bring it in. We'll measure the tires, check the geometry, and tell you straight up whether to keep it, upgrade the tires, or replace the bike. No upsell — if 47 mm Schwalbe Marathon Plus tubeless on your current wheelset gets you to the bridging threshold for $180 installed, that's the recommendation.
