Overview
The Philiam FX1 is a dual motor electric dirt bike with peak output up to 5000W combined, a 52V battery available in 32Ah or 23Ah capacity, and 26 inch fat tires with full suspension. It targets riders who want off road power alongside a claimed top speed of 35 mph.
Owners describe genuine power and a comfortable ride across a range of heights and weights, and the 4.6 rating reflects a largely satisfied buyer base. One reviewer's measured test of the combined motor output came up short of the advertised figure, worth noting for anyone buying on that number specifically.
- Dual motor, up to 5000W peak combined
- 52V battery in 32Ah or 23Ah options
- 26 inch fat tires with full suspension
- Claimed top speed of 35 mph
Who it's for
Suits riders who want strong off road torque and dual motor flexibility, switching to single motor for range and dual for climbs or dirt. Less suited to anyone who needs the advertised power figure to hold up under a precise test.
Pros and cons
- Dual motor mode adds torque for climbs and dirt
- Comfortable fit across a range of rider sizes
- Responsive customer service noted by several buyers
- Combined motor output measured short of advertised figure
- No turn signals
- Horn placement sits close to the headlight
Performance notes
Fit comments span a wide range of rider heights and weights without complaints of cramped ergonomics. One owner who tested the combined output found it fell short of the advertised figure, and another flagged the horn's placement too close to the headlight along with the absence of turn signals.

Frequently asked questions
Does the FX1 actually hit its advertised 5000W combined output?
One reviewer who tested it found the real combined output did not reach the advertised figure, so treat that number as a peak spec rather than a fixed guarantee.
