Overview
A retro styled 20x4 inch fat tire electric bike from Sisigad, built around a motor rated to 1500W peak and a 48V 15Ah removable battery. Positioned for city commuting, off roading, and mountain trail use with 7-speed gearing.
A dual battery configuration is mentioned by at least one buyer as an available option for extended range.
- 48V 15Ah removable battery rated up to 60 miles range
- 20x4 inch fat tires on a steel frame
- 7-speed gearing, UL 2849 certified battery
- Spoke-free wheel design cited by one reviewer as more durable
Who it's for
Riders comfortable doing their own bike assembly and willing to work through a menu system to reach full speed, in exchange for a rugged steel frame and swappable battery. Not the choice for someone who wants full advertised speed the moment it's unboxed.
Pros and cons
- Dual battery option supports extended backup range
- Spoke-free wheels avoid bent-spoke failures
- Heavy steel frame makes solo assembly harder
- Some hardware bolts strip or round off
- Full speed requires an undocumented menu unlock
