E-bikes on bike paths: no cars doesn’t mean it’s safe

After being struck by an e-bike, a bicyclist was killed on a bike path near a high school, not far from us here in Contra Costa County after a collision.

No freeway. No traffic. No intersection.

A bike path.

That’s the part that gets people.

Most people think of bike paths as the safe alternative to the road.

But what we’re seeing more and more—especially with e-bikes—is that “no cars” doesn’t mean no risk.

Walk any shared path today—whether it’s a neighborhood greenbelt or a well-known path like the Iron Horse Trail*—and you’ll see it right away:

Fast-moving e-bikes. Close passes. People stepping out of the way at the last second.

And a whole lot of near-misses.

This isn’t just frustrating. It’s a problem.

*In case you’re not familiar with it, Iron Horse Trail runs north-south through Contra Costa and Alameda counties, connecting cities from Concord to Pleasanton, including Walnut Creek, Alamo, Danville, and San Ramon, typically serving as a major recreation and commuting route.

This is not the same as riding in the street

From a legal and safety standpoint, bike paths are a completely different environment than roadways.

On the road:

• There are clear rules
• There is consistent enforcement
• Drivers are trained and licensed

On a shared path?

Not so much.

• No one’s checking what class of e-bike you’re riding
• No one’s pulling people over for speed
• No one’s making sure riders know what they’re doing

On trails like the Iron Horse, you’re not dealing with local police in the same way. These areas are primarily managed by park systems, and enforcement is limited.

That matters.

Everyone is sharing the same narrow space

You’ve got:

• people walking dogs
• kids on scooters
• joggers with headphones
• cyclists moving at normal bike speeds
• and now… e-bikes moving a lot faster than any of them expect

All on the same path.

No lanes. No separation. No real buffer.

That’s where things start to break down.

The part no one wants to say out loud

A lot of the close calls we’re seeing involve younger riders.

Not all of them. But enough that it’s noticeable.

They’re riding faster than pedestrians expect. Passing tighter than they should. Moving in ways that would be clearly unsafe—or illegal—if they were in the street.

And most of the time?

Nothing happens.

No ticket. No warning. No consequence.

Until something finally does happen.

When it goes wrong, it goes wrong fast

These aren’t low-speed collisions.

An e-bike moving 20+ mph hitting a pedestrian—or even another cyclist—is enough to cause serious injury.

• broken bones
• head injuries
• people getting knocked down hard on pavement

And when that happens, the question becomes:

Who’s responsible?

This is where it gets real

If a rider causes an accident on a shared path:

• they can be held responsible
• and if it’s a minor, their parents may be pulled into it too

And now you’re not talking about a “bike accident.”

You’re dealing with medical bills, insurance, and potential legal claims.

All from something that started as a ride on a “safe” path.

What people need to understand

Bike paths haven’t caught up to e-bikes.

The speed is different. The risk is different. But the environment hasn’t changed to match it.

So you end up with:

• higher speeds
• mixed experience levels
• limited oversight

That combination is where accidents come from.

So what are the actual rules on bike paths?

This is where things start to fall apart for most people.

California does have rules. They’re just not as simple as people think.

E-bikes are divided into three classes:

• Class 1: Pedal assist, up to 20 mph
• Class 2: Throttle, up to 20 mph
• Class 3: Pedal assist, up to 28 mph

Here’s the part that matters:

• Class 1 and 2 are usually allowed on bike paths
• Class 3 is often not allowed on shared-use trails

But it doesn’t stop there.

Local cities and park systems can make their own rules—and they do.

So you can be riding legally in one area…

…and then cross into another trail or city where the rules are different—and now you’re not.

Most people don’t know that.

And on shared paths, there’s usually no one there checking or explaining it.

So people just ride.

Until something happens.

If you’re a parent, don’t assume your kid knows this

Most don’t.

They don’t think about speed the same way drivers do.

They don’t think about how unpredictable pedestrians are.

And they definitely don’t think about what happens after an accident.

That’s a conversation worth having before something forces it.

Because “no cars” doesn’t mean no risk

It just means the risks are different.

And right now, a lot of people are learning that the hard way.
