Subject:
Bike Lanes, Street Use, and Micro-Mobility Challenges Facing Cambridge
1. Introduction
Cambridge is proudly one of the most walkable and bikeable cities in the U.S., but with
the emergence of new technologies and personal transportation devices, sometimes referred to as
“micro-mobility,” there is a lot of ambiguity around who can legally ride what where. Human
powered and motorized (generally electric) bicycles, tricycles, scooters, one-wheels, and
skateboards are in use in Cambridge, but where do they belong? How will the future of last mile
delivery be integrated? What should the future of ‘electric rideables’ be in Cambridge? One
report expects over 150 micro mobility models by 2020, and forecasts the micro-EV/personal
transportation device market to reach more than $33 billion by 2026.1
This memo reviews current City and State regulations, the types of devices in use and
suggests the City focus on creating an appropriate regulatory framework to allow the safe and
legal use of micro-mobility devices. Other dense cities such as Singapore have already started to
discuss this issue and it is possible we could learn from them.2
This memo is not intended to be a comprehensive review of applicable laws and
regulations (in fact, some of the analysis may not be 100% accurate) but it is, rather, meant to
highlight the need to clarify what types of transportation modes should have access to what parts
of the City’s Right of Way, and under what conditions, before the City goes much further in its
street safety design efforts. Regulations governing these micro-mobility devices can be confusing
2
even as they are increasing in both
capabilities and use. Something as
mundane as parking
presents challenges as Cambridge
regulations forbid motorized vehicles from
using bicycle parking facilities, although
the definition of “motorized vehicles” is
not readily clear in the regulations.4 Some
research indicates that, for older riders
especially, the addition of electric power to
a traditional bicycle can be deadly.3
Given the current confusion around
the use of these vehicles and the likelihood
of their vastly increased use in the near
future, it is important for municipalities
like Cambridge to get ahead of these regulatory challenges without waiting for other
communities to lead the way.
2. Definitions
In Article 1 of the Cambridge Traffic, Parking, and Transportation Department (TPTD)
Regulations, the City provides a list of definitions, of which relevant terms are copied below.4
BICYCLE
Every device propelled by human power upon which any person may ride,
having no more than two tandem wheels either of which is 8” or more in
diameter.
BIKE LANE
A lane on a street restricted to bicycles and so designated by means of
pavement coloring, lines or other appropriate markings.
ELECTRONIC PERSONAL ASSISTIVE MOBILITY DEVICE
A motorized self-balancing device that transports an individual standing
on a platform between two wheels and including an upright handle.
INLINE SKATES
Any shoe with an attachment of four or more wheels aligned in a linear
fashion.
MOTORIZED BICYCLE5
A pedal bicycle which has a helper motor, or a non-pedal bicycle which
has a motor, with a cylinder capacity not exceeding fifty cubic
Figure 1
3
centimeters, an automatic transmission, and which is capable of a
maximum speed of no more than thirty miles per hour.
MOTORIZED SCOOTER
A vehicle consisting of any two wheeled device that has handlebars or
other steering device, designed to be stood or sat upon by the operator,
which is powered by a motor and not defined as a “motor vehicle” or
“motorized bicycle” under Chapter 90, except that an electronic personal
assistive mobility device or other mobility device for a person with
disabilities shall not be considered a motorized scooter under this section.
MOTOR VEHICLE
All motorized conveyances or vehicles that are subject to G.L. c.90 except
as may otherwise herein be defined.
G.L. c.90: “All vehicles constructed and designed for propulsion by power other
than muscular power…except wheelchairs…[and] motorized bicycles”.5
PEDESTRIAN
Any person afoot or riding on a conveyance moved by human power,
except bicycles, inline skates, scooters and skateboards.
SCOOTER
A vehicle consisting of a long foot board between two small end wheels,
aligned in a linear fashion, controlled by an upright steering handle
attached to the front wheel, which is powered by a human.
SKATEBOARD
A non-motorized vehicle consisting of a long foot board between two sets
of wheels, with steering controlled by weight distribution.
TAXICAB STAND
An area in the roadway in which certain taxicabs are required to park
while waiting to be engaged.
VEHICLE
Every device in, upon or by which any person or property is or may be
transported or drawn upon a highway, including bicycles and any
attachments thereto when the provisions of these rules are applicable to
them, except other devices moved by human power or used exclusively
upon stationary rails or tracks.
3. Current Bike Lane Regulation
Cambridge Bicycle Lanes, as discussed above, seem clearly restricted to bicycles,
although state law states that “Motorized bicycles may be operated on bicycle lanes adjacent to
the various ways, but shall be excluded from off-street recreational bicycle paths”6 and that “A
person operating a motorized scooter upon a way shall have the right to use all public ways in the
4
commonwealth….”7 However, the Cambridge Community
Development Department states bike
lanes are “exclusively for use by bicyclists…motorists are
not allowed to travel in bike lanes and are subject to a $100
fine if they do so.”8 The term “motorist” is not defined in the
TPTD Traffic Regulations nor the MA. G.L. c.90. Nor is it
immediately clear what “adjacent” means when it comes to
non-grade separated bike lanes.
Under Cambridge’s current regulations then, it seems
that anything that is not a bicycle or a motorized bicycle
(often referred to as a “moped”) is not allowed in a bicycle
lane. This means that skateboards, motorized bicycles of
more than 50 CM, electric skateboards, one-wheels and
various other micro-mobility devices are apparently not
currently legally allowed in designated bicycle lanes.
Skateboard regulation is very confusing as the
Traffic, Parking, and Transportation Regulations (Dec
2017) states that scooters, inline skates, skateboards, and
electronic personal assistive mobility devices are to be
ridden on sidewalks, except in business districts, and
should yield to pedestrians,4 but City Ordinance (Aug
2004) states that traditional skateboards are currently not
to be used on City property, such as sidewalks and regular
parks.9
From an enforcement standpoint, the number of
cubic centimeters associated with a motorized bicycle can
be difficult to determine simply by looking at the vehicle.
Given that even a 50 cm scooter can go roughly 30 MPH,
the difference in motor size, as applied to bike lanes, may
be irrelevant. 10
Rules of the Road for Bicyclists and Bike Lanes11
• When riding on-street, bicyclists are generally considered vehicles. While City
documents say cyclists must follow all traffic rules that drivers follow, this assertion
is simply not true as cyclists do not have to, for example, signal turns if they deem
doing that is dangerous.12
• Bicyclists are permitted to ride on sidewalks, except for in business districts, and
must travel near walking speed and always yield to pedestrians and give an audible
warning when passing.
• A white front light (visible at 500 feet), rear red reflector or light (visible at 600 feet),
and pedal reflectors must be affixed to the bicycle from 30 minutes after sunset to 30
minutes before sunrise.
• Bicyclists may not carry packages, bundles, or articles unless secured in a basket,
rack, or trailer.
• It is illegal to open the door of a parked vehicle unless it is reasonably safe to do so,
checking for vehicle, bicycle, and pedestrian traffic.13

• It is unclear if motorists can stop in bike lanes. “No person shall…stop a vehicle…on
the roadway in a manner that will obstruct fully or partially any Bicycle Lane or
Bicycle Facility,”4 but given the prevalence of bike lanes and relevant regulatory
language of “otherwise than for the purpose of, and while actually engaged in
receiving or discharging passengers” it is not clear how absolute that prohibition is.
4. Types of Personal Transportation Devices
Persons using human powered wheelchairs are considered
pedestrians and belong on sidewalks, but persons using
motorized wheelchairs are not considered pedestrians.
Tricycles are not considered bicycles and do
not have a defined space to ride.
Per Cambridge regulations, a motorized scooter is ‘A
vehicle consisting of any two wheeled device that has
handlebars or other steering device, designed to be
stood or sat upon by the operator, which is powered by
a motor and not defined as a “motor vehicle” or
“motorized bicycle” under Chapter 90, except that an
electronic personal assistive mobility device or other
mobility device for a person with disabilities shall not
be considered a motorized scooter under this section.’4
For something to be a motorized bicycle, it must have
pedals.

Many of the above devices are examples of micro-mobility devices that either do not fit
any City or State definitions or regulations or are categorized in such a fashion as to only allow
legal use in general, and dangerous, street traffic. They vary from one to four wheels, have a
wide range of speeds, and, as noted above, add a variety of challenges to already congested
sidewalks, bike lanes, bike racks, and roadways.
5. Future Considerations
Travelling the last mile in any transportation industry is often the most expensive and
time consuming part of the trip, and the transportation industry has begun overhauling last mile
mobility with car sharing, ride hailing and bike sharing. Last mile package and food delivery is
also becoming disrupted through services like Amazon’s drone initiative and UberEats.

Droids, drones, autonomous ground vehicles, crowdsourcing, and bike couriers are posed
to reinvent last mile delivery in the next decade. McKinsey reports 80% of packages will be
delivered by autonomous vehicles.14 An Estonian company conducted 8,000 miles of droid
delivery testing across 40 cities in 12 countries, encountering 1 million pedestrians without
injury.15, 16 While this memo does not cover these issues, rapid technology and industry changes
are already forcing Cambridge to examine the use of its streets, bike lanes, and sidewalks and
where autonomous droids and similar vehicles fit in. A static view of cars on streets, bikes in
bike lanes, and everything else on sidewalks does not reflect the emerged and emerging micro-
mobility options in use today, much less their expanded future use, and will, arguably,
compromise our most vulnerable modes of transportation.
6. Conclusions
The future of transportation in Cambridge is going to include a larger and larger amount
of micro-mobility devices such as electric powered one-wheels, electric bicycles, mopeds, hover-
boards, electric wheelchairs, and more. These devices, like bicycles, present safety challenges on
our sidewalks and, also like bicycles, are vulnerable users of roadways. Subject to existing state
law for off-road use of motorized bicycles, they should have access to all areas where bicycles
can operate and park but speeds should be limited to roughly 12 miles per hour. They should also
be subject to the same lighting, helmet and braking requirements that bicycles are subject to and
gas powered vehicles should not exceed more than 40 decibels at the muffler under any
conditions. While enforcement of these requirements would be a challenge, they are necessary to
ensure that these vehicles do not pose an undue danger to other users or our ROWs.
The City’s Department of Traffic, Parking and Transportation should immediately create
and implement a regulatory program that meets the above suggestions. If state law does not
provide the Department to issue such regulations, the City Council should either ask for home

rule authority to all such a local regulatory program or should work with state officials to create a
statewide legal framework to govern these new transportation devices.
The ‘regulatory entrepreneurship’ highlighted by these new micro-mobility devices
demonstrates the need for Cambridge to be very aggressive in identifying new trends and
developing both regulatory programs and physical infrastructure to make sure they are
accommodated in a manner that best meets our dense cities urban mobility challenges.
