Subject: Mineta Transportation Institute Update on
2025 Electric Bicycle Safety Study
District: All
Recommended Action
Receive an update from the Mineta Transportation Institute regarding its December 2025
study, Exploring Electric Bicycle Safety Performance Data and Policy Options for California,
conducted as directed by California Senate Bill 381 (2023), and provide feedback.
Discussion
The Mineta Transportation Institute (MTI) is a university transportation center located within
the Lucas College and Graduate School of Business at San José State University. MTI’s mission
is to increase mobility for all by improving the safety, efficiency, accessibility, and convenience
of our nation's transportation system through research, education, workforce development
and technology transfer.
As noted on the MTI website (https://transweb.sjsu.edu/):
MTI’s 2025 study, Exploring Electric Bicycle Safety Performance Data and Policy Options
for California, was conducted as directed by Senate Bill 381 (Min, 2023), which called for
research to help policymakers develop effective laws and policy to support the twin
goals of expanding electric bicycle use and protecting the safety of electric bicycle riders
and other road users. The three major strands of findings presented in this report are (1)
a review of how California and other states (and countries) regulate electric bicycle use,
(2) a review of the electric bicycle safety literature, including original analysis of primary
data on crashes, injuries, and deaths, and (3) strategies that the state could adopt to
promote the safe use of electric bicycles. The strategies discussed include revising the
way the California Vehicle Code defines and regulates electric bicycles, opportunities for
improving electric bicycle safety data quality and analysis, building safe infrastructure
for electric bicycling, and public education on electric bicycle rules of the road and safe
riding practices.

Exploring Electric Bicycle Safety Performance Data and
Policy Options for California
Asha Weinstein Agrawal, PhD, and Kevin Fang, PhD
The recent emergence of electric bicycles has
generated both excitement over their potential
as affordable, climate-friendly transportation
and concerns about their safety for riders and
bystanders.This study, conducted as directed
by California Senate Bill 381 (2023), assembled
data and expert insights to help policymakers
develop effective laws and policy that will
support the twin goals of expanding electric
bicycle use and protecting public safety.
What is an “electric bicycle”?
Under California law, as in most states, electric
bicycles must have 2 or 3 wheels, operable
pedals, and an electric motor that produces
no more than 750 watts of power. Further,
California segments legal bicycles into three
classes on the basis of the top motor-assisted
speed (20 or 28 mph) and method of activating
motor assistance (by pedaling and/or via a hand
throttle).
Complicating any discussion of electric bicycle
safety, many devices that people perceive to
be “electric bicycles” are actually not legal
electric bicycles because they have motor
power in excess of 750 watts and/or assist
speeds above the 20 or 28 mph limit. Adding to
the confusion, some devices sold and shipped
as meeting power and speed limits for electric
bicycles are easily modified to higher power
outputs and speeds.
Rules for riding electric bicycles
The California Vehicle Code states that “an
electric bicycle is a bicycle,” thereby granting
electric bicycles most of the rights and
responsibilities of conventional bicycles.
There are just a few extra restrictions on
electric bicycles, such as age minimums and
adult helmet requirements for some types of
electric bicycles.
What we do—and don’t—know about
safety
A major stumbling block to understanding
electric bicycle safety risk is the fact that some
proportion of crashes, injuries, and fatalities
attributed to “electric bicycles” involve higher-
power devices that are not legal electric
bicycles. Counts of electric two-wheelers parked
at a dozen northern California middle and high
schools suggest that, at least for young riders
in those communities, as few as 12% of the
devices may be legal electric bicycles.
Keeping this major data quality limitation in
mind, some patterns about electric bicycles
emerged from our original analysis of crash,
injury, and fatality data, plus a review of over
200 published electric bicycle safety studies:
•The number of incidents attributed to electric
bicycles has risen sharply in recent years.
That finding in and of itself is not surprising,
though, since electric bicycle popularity has
also climbed rapidly.
•Despite a rapid increase in incidents, electric
bicycle crashes, injuries, and fatalities are,
on the whole, far less common than incidents
involving conventional bicycles.

• When injuries do occur, electric bicycle riders
have somewhat more severe outcomes than
conventional bicycles, on average, with more
serious medical diagnoses and/or higher
hospitalization rates.
• Most electric bicycle injuries appear to
result from solo crashes, but vehicle
crashes appear to be involved in a majority
of fatalities.
• Nationwide, people injured and killed on
electric bicycles tend to be older than those
in incidents with conventional bicycles. That
said, emergency rooms in communities
where electric bicycles are popular among
teenagers report numerous young people
injured.
A major stumbling block to
understanding electric bicycle safety
risk is the fact that some proportion
of crashes, injuries, and fatalities
attributed to “electric bicycles” involve
higher-power devices that are not
legal electric bicycles.
Policy options
The State of California can most effectively
support safe electric bicycle riding with a
package of complementary actions that include
educating all road users about electric bicycle
rights and responsibilities, building safe biking
infrastructure, re-considering how the California
Vehicle Code defines and regulates use of
electric bicycles, and improving data collection
and analysis of electric bicycle related incidents
to inform policy changes. Specific actions
recommended in the report include:
• Building high-quality bicycle infrastructure
on state facilities and supporting local
government efforts to do the same
• Adopting strict disclosure requirements on
retailers, so that buyers understand whether
the device is a legal electric bicycle under
statute, which class of device it is, and state

rules on who may ride the device
• Publishing a handbook of Rules of the Road
for riders of electric bicycles, conventional
bicycles, and other micromobility devices
that presents the full set of rules for these
modes as defined in the California Motor
Vehicle Code
• Specifying that the 750 watt maximum
motor power refers to peak power, not
continuous power for legal electric bicycles
• Revising the procedures that medical staff
and police officers use to report incidents
involving two-wheeled electric devices so
that only those incidents involving legal
electric bicycles are classified as such

The analysis presented was developed as part of a larger study about
e-bike safety policy required by CA Senate Bill 381 (Min -2023)
Overview
A. E-bike safety concepts
B. How dangerous are e-bikes?
C. Revise the e-bike definition & class system
A.
E-bike safety concepts
What EB safety concerns have been identified?
1.EB riders are injured or killed as a result of:
•Collisions with motor vehicles
•Solo crashes
2.Other road users are
•Injured or killed by EB riders
•Intimidated by aggressive or careless EB riders
The primary types of safety data available
1.Medical: hospital & EMS records, death certificates
2.Police: collision reports
ALL have major limitations:
•High probability of devices being miscategorized
“EB” data includes electric pedal devices with higher speeds
or more powerful motors than are legal for EBs
•E-bike class rarely reported
•The is no record for many (most?) incidents
What we want to know about EB incidents to set policy
1.How many incidents occur and how severe the outcomes are
2.Incidents per exposure (per trip or per distance traveled)
To calculate, need the # of EB trips taken and/or distances traveled
3.Factors associated with more frequent incidents
Examples: specific street types, EB rider characteristics, EB rider
behaviors, or motorist behaviors
4.How the numbers and types of EB injuries compare to similar
devices (bicycles, e-scooters, etc.)
B.
How dangerous are EBs?
Key findings from CA, US, & global safety data
•# of reported EB crashes/injuries each year is rising, but so are EB #s
•Far fewer people are reported injured on EBs than on most other
travel modes, including conventional bicycles and cars
•Majority of reported EB incidents involve adults
•Very few bystanders injured
•Many (most?) of the reported “e-bike” incidents likely did not involve
legal EBs, especially in California
There is statewide evidence on device types, but 2025 counts of
“bicycle-shaped devices with electric motors” parked at Bay Area
middle and high schools found 88% were not legal e-bikes
So, legal EBs may actually be relatively safe

Opportunities for Carlsbad
Overall approach
1.Educate the whole community, especially kids and parents,
about:
•Identifying legal EBs vs. not-EBs
•Rules for riding EBs
2.Keep rules about using EBs as simple as possible
3.Collect better data on e-bike crashes and injuries to
understand the true nature of local safety issues
Help community members choose legal EBs
Don’t expect consumers to research state EB laws before a purchase!
1.Share information on legal vs. not-legal devices through
schools, targeting both kids and parents
2.Encourage retailers to disclose to shoppers whether or not the
device is a legal EB, the EB class, and California rules on who
may ride the device
Proposed legislation would require retailers to do this
3.Work with local media to help educate the community
Help people learn the rules for riding EBs
We cannot expect people to follow rules they don’t know
1.Run educational campaigns to educate ALL road users on EB rules of
the road
2.Offer bicycle and EB rider education in all schools
•Target both students and parents
3.Prominently sign any EB rules specific to a place (e.g., speed limit on a
shared-use path)
Advocate for standardized riding rules
Advocate for good state-wide rules, including on ages & helmet use,
rather than focusing on local regulations
It is impractical to expect everyone riding an EB in Carlsbad to know city-
specific rules
Study the nature of local EB crashes & injuries
Better data and analysis is needed to understand the safety problems well
enough to craft effective policy solutions
1.Carlsbad can work with police, local hospitals, and local EMS to collect
better data
•Document the device make, model, and key characteristics (e.g.,
throttle)
•Collect good data on crash circumstances (location, what was
happening, light and weather, etc.)
•Document more crashes
2.Analyze the data to understand causes
