The Power Core
Built Around Bafang Mid-Drive Power
Every bike in this lineup runs a Bafang mid-drive motor with integrated torque sensing — power that responds intuitively to your pedal input instead of a jerky on/off throttle. Specter-S 3.0 steps up to Fifield's flagship G510 tune with the strongest braking in the lineup. Paired with full suspension across the board, this is a fleet built to take on rougher trails without punishing your ride.
The Suspension System
Soft Tail Linkage Suspension
Every bike in this lineup shares a soft tail linkage design, letting the rear triangle pivot and absorb trail impact instead of transferring it straight to the frame. Paired with the fork up front, it's full suspension built to take the edge off rough terrain ride after ride.
Questions? Answered.
What's the real difference between these three bikes?
They share the same 1000W power class and full suspension, but differ in battery size, motor tuning, and braking hardware. Rogue Wave Pro carries the largest battery for the longest range. Specter-S 3.0 runs Fifield's flagship motor with an expandable second battery and the strongest brakes, built for backcountry and hunting use. Fat-HS delivers the same core power at the most accessible price.
Which one should I get if I'm new to eMTBs?
Fat-HS is the easiest entry point — full suspension and real power without the premium price tag. If you know you'll be riding longer distances regularly, Rogue Wave Pro's larger battery is worth the step up.
Can I extend the range on any of these?
Specter-S 3.0 supports an optional second battery for extended range on longer trips. Rogue Wave Pro and Fat-HS ship with a single battery as standard.
What does the warranty cover?
Every Fifield e-bike includes a 2-year warranty on the frame, battery, and motor, excluding normal wear-and-tear items like tires, brake pads, and chains.
How long does shipping take?

Can I test ride before buying?
