Urtopia rates this bike for up to Up to 95 miles of range. Real-world range can vary based on pedal-assist level, rider weight, bike weight, terrain, speed, temperature, tire pressure, cargo, and throttle use.

Riders using mostly throttle or the highest assist setting will often see closer to about half of the advertised maximum range. Lower assist levels and more rider pedaling can significantly extend range.

This bike uses a 750W Hub-Drive, 90 Nm, with up to 1250W of peak output.

The motor's nominal power describes the power it is designed to provide continuously. Peak power is the higher amount it can deliver for short periods, such as accelerating from a stop or climbing a hill.

For eBike classification and legal compliance, nominal motor power is generally accepted as the relevant power figure rather than the short-duration peak power number. Regulations can vary by state and local jurisdiction, so riders should always follow the rules where they ride.

Higher motor power can provide stronger acceleration and better performance on hills or with heavier riders and cargo, but wattage alone doesn't tell the whole story. Torque, bike weight, gearing, wheel size, and the motor controller also affect how powerful an eBike actually feels.

This bike uses a 835Wh, LG M58 Li-ion, Removable battery. Battery capacity on eBikes is commonly measured in watt-hours (Wh). The higher the watt-hour number, the more energy the battery can store.

As a general rule, a larger battery can provide more riding range, but battery size alone doesn't determine how far an eBike will go. Bike weight, motor efficiency, assist level, throttle use, rider weight, terrain, speed, tire pressure, temperature, and cargo can all affect battery consumption.

Watt-hours also make it easier to compare battery capacity between different eBikes. For example, a 700Wh battery stores roughly 40% more energy than a 500Wh battery, even if the bikes use different battery voltages.

Keep in mind that a larger battery usually adds some weight and can take longer to charge, so the biggest battery isn't necessarily the best choice for every rider.

This Urtopia Carbon Atom has an assisted top speed of 20 mph by default, 28 mph upon unlock and can be configured for Class 2 operation.

Under the commonly used three-class eBike system:

Some eBikes can be configured for more than one class, allowing the rider to adjust the bike for different riding locations or regulations. eBike laws and trail-access rules vary by state and local jurisdiction, so riders should check the rules where they plan to ride.

eBikes typically use either a torque sensor or a cadence sensor to determine how the motor responds while you pedal.

Torque sensors measure how hard you're pedaling and provide motor assistance in proportion to your effort. This generally creates a smoother, more natural, and more responsive riding experience. The harder you pedal, the more assistance the motor provides.

Cadence sensors primarily detect whether the pedals are turning. Once you begin pedaling, the motor provides assistance based largely on the selected assist level rather than how much force you're putting into the pedals.

Torque sensors are generally considered the more refined system and have become increasingly common on modern eBikes. Cadence sensors can still be useful for riders who prefer the motor to provide more assistance with less pedaling effort.
