A Class 2 electric bike, or ebike, is a specific category within the broader classification of electric bicycles. Here are the key characteristics of a Class 2 ebike:

Motor Assistance: A Class 2 ebike is equipped with a motor that can be used to assist the rider's pedal power or to propel the bike without pedaling. This is a distinctive feature of Class 2 ebikes, as they have a throttle-assisted mode.
Speed Limitation: The motor assistance on a Class 2 ebike is limited to a maximum speed of 20 miles per hour (mph) or 32 kilometers per hour (km/h). Once this speed is reached, the motor assistance will automatically cut off, and any further acceleration must be done by the rider's own pedaling effort.
Pedal Assist and Throttle: Besides the throttle mode, Class 2 ebikes often include a pedal-assist feature, where the motor provides assistance only when the rider is pedaling. However, the distinguishing factor of Class 2 is the throttle capability, which can propel the bike without the need for pedaling.
Legal Considerations: The classification of ebikes, including Class 2, varies by location. Different regions and countries may have specific regulations regarding the use, licensing, and access of ebikes on roads, bike paths, and trails. In many jurisdictions, Class 2 ebikes are treated similarly to traditional bicycles, with no need for a driver's license, registration, or insurance.
Uses: Class 2 ebikes are popular for a variety of purposes, including commuting, recreational riding, and even light off-road use. The throttle feature makes them particularly appealing for riders who may need or want the option to ride without pedaling, such as when carrying heavy loads or during long commutes.
Battery and Range: Like other electric bikes, Class 2 models are powered by rechargeable batteries. The range or distance the ebike can travel on a single charge, varies depending on the battery capacity, rider weight, terrain, and level of motor assistance used.


In summary, a Class 2 electric bike is defined by its motor's capability to assist up to 20 mph, both through pedal assistance and throttle control. This type of ebike offers a blend of traditional cycling and motor-assisted travel, appealing to a wide range of users.

A Class 3 electric bike, also known as a "speed pedelec," is a high-performance category of electric bicycle designed for faster commuting and urban travel. Below are its defining characteristics:

Motor Assistance & Speed Limitation
Class 3 ebikes provide motor assistance only when the rider is pedaling (pedal-assist mode) and do not include a throttle. The motor assistance cuts off once the bike reaches a maximum speed of 28 mph (45 km/h).

Key Features

• Pedal-Assist Exclusive: No throttle propulsion; motor engagement requires active pedaling.
• Enhanced Speed: Optimized for efficient commuting, with assist capping at 28 mph.
• Safety Components: Often equipped with reinforced brakes (e.g., hydraulic discs), lights, and speedometers for safe operation at higher speeds.

Legal Considerations
Regulations for Class 3 ebikes vary by region. In the United States, they are typically allowed on roads and bike lanes but may be restricted from multi-use paths. Some states require riders to be at least 16 years old, wear helmets, and/or have a speedometer installed. Licensing and insurance are generally not required.

Common Uses
Ideal for urban commuters seeking to reduce travel time, navigate hills effortlessly, and maintain pace with city traffic. The higher speed capability makes them less suitable for shared recreational paths.

Battery and Range
Like other ebikes, range depends on battery capacity, terrain, and riding style. The increased speed and power demand may reduce range compared to Class 1 or 2 models under similar conditions.

In summary, a Class 3 ebike prioritizes speed and efficiency through pedal-assist technology, catering to riders who need faster, motor-augmented travel while adhering to specific legal and safety requirements.

A commuter ebike is a type of bicycle designed specifically for commuting, but with the added feature of electric assistance. Here are some key characteristics and features of commuter ebikes:

• Electric Motor and Battery: These bikes are equipped with an electric motor and a rechargeable battery. The motor assists the rider's pedaling effort, making it easier to travel longer distances, climb hills, and accelerate from a stop without getting as tired as on a traditional bike.
• Design for Commuting: They are typically designed for comfortable and efficient travel over distances typical in daily commutes. This might include features like a comfortable seat, an upright riding position, and sometimes even a built-in rack or cargo space for carrying personal items or work essentials.
• Range and Speed: The range of a commuter ebike (how far it can go on a single charge) varies depending on the battery capacity, motor efficiency, rider's weight, terrain, and level of pedal assistance used. The speed can also vary but is often capped at a certain limit to comply with local regulations (usually no more than 28 mph).
• Pedal Assist and Throttle Modes: Many commuter ebikes come with a pedal-assist system (PAS) where the motor provides assistance only when the rider is pedaling. Some also have a throttle mode, allowing the bike to be powered by the motor alone without pedaling.
• Durability and Maintenance: These bikes are generally built to be durable and require regular maintenance, similar to traditional bicycles, with the addition of caring for the electric components like the motor and battery.
• Urban-Friendly Features: They often include features that are particularly useful in urban settings, such as lights for visibility, fenders to guard against street spray, and locks for security.

Commuter ebikes are a popular choice for those looking to reduce their carbon footprint, avoid traffic congestion, and make commuting more enjoyable and less physically demanding compared to traditional bicycles or cars.

A fat tire ebike is a type of electric bicycle that features notably wide tires, often 4 inches or more in width. These wide tires offer several advantages:

Improved Traction and Stability: The larger surface area of fat tires provides better traction on various surfaces, making them suitable for off-road conditions, snow, sand, and muddy trails.
Comfort: Fat tires can absorb shocks more effectively, offering a smoother ride over bumpy or uneven terrain.
Electric Assist: Like other ebikes, fat tire ebikes are equipped with an electric motor that assists the rider. This motor can be activated by pedaling or, in some models, by a throttle. It helps riders travel longer distances, climb hills more easily, and reduce the effort required for pedaling.
Versatility: They are versatile in handling different kinds of terrain, which makes them popular for outdoor enthusiasts who enjoy trail riding, as well as for urban commuters who face a variety of road conditions.
Design and Build: Apart from the wide tires, these bikes often have a sturdy frame and are designed to handle extra weight and stress, making them durable.

Pedal assist bicycles are electric motor assisted bikes. The function of the pedal assist is to augment the rider's own physical power to save energy, so they can ride farther and longer with as little effort as possible. Spacevelo ebikes have five levels of pedal assist. That means more assisted power as you increase the levels while you ride. In addition, when it comes to pedal assist there are two types of sensors that are industry standards when it comes to the mechanism behind this function: cadence and torque.

The cadence sensor, when in use, produces a prescribed amount of power as soon as it recognizes the rider’s activity on the pedals. The power increases with each PAS level, and is sustained throughout the entire ride until they stop pedaling. Below are key benefits that the cadence sensor can offer each rider and how that translates to their experience.

The torque sensor is all about rhythm. There is a natural relationship between the bike and the rider that can feel like they're riding a standard bicycle. A torque sensor picks up on the riders pedaling pressure and augments it. The more pressure applied by the rider, the more power they’ll receive from their ebike.

At Spacevelo, our customers are the center of our world. Everything we do is to ensure that you, the customer, continue to ride happily. That’s why Spacevelo’s support team is available to answer any ebike questions, including troubleshooting that will get you back in the saddle to enjoy your ride.
