2025 Seaside3.0 Lightweight Commuter E-Bike

Commuter e-bikes have become a key solution for urban mobility in 2025, offering an alternative to traffic congestion. Fifield, a brand based in Boston, designs e-bikes that emphasize practicality, comfort, and reliable performance across their range.

Seaside3.0: Designed for First-Time E-Bike Users

The Seaside3.0 model caters to newcomers with its accessible design. A step-through frame allows easy mounting, suitable for riders with mobility concerns or those wearing casual attire. Weighing approximately 45 pounds, it is lightweight enough for carrying upstairs or onto public transport.

Power comes from a 350W Bafang rear-hub motor providing 45Nm of torque, assisting with gentle inclines without strain. The battery offers a range of 30 to 40 miles per charge, covering typical daily commutes. A Suntour NEX fork absorbs road imperfections, and hydraulic disc brakes ensure consistent stopping power in various conditions.

Seaside4.0: Enhanced Performance for Regular Commuters

For daily commuters seeking advanced features, the Seaside4.0 includes a 500W Ananda M100 mid-drive motor with 130Nm of torque. This mid-drive configuration improves traction on hills and delivers a more natural riding feel through torque sensing, which adjusts assistance based on pedaling effort.

The range extends to 40–60 miles, allowing for longer trips or detours. Additional safety elements include integrated turn signals, making it suitable for busy urban environments.

Bonfire500: Built for Long-Distance and Speed

The Bonfire500 is a Class3 e-bike capable of speeds up to 28 mph, ideal for longer commutes or riders who need to match traffic flow. It uses a 500W Dapu rear-hub motor with 90Nm torque, paired with a 27-speed drivetrain for versatile handling on diverse terrains.

With a range of around 50 miles, it reduces range anxiety for extended journeys. Logan HD-E500 hydraulic brakes provide reliable high-speed stopping power.
