Questions and answers
- Which is better for commuting?
- The Trek FX+ 2. It is about 40 lb, comes with lights, fenders, and a rack, and charges in about 2 hours. The Aipas is 90 lb and needs accessories added for daily commuting.
- Which handles hills and rough terrain better?
- The Aipas. Its 1800W motor and 110 Nm of torque, full suspension, and 26x4.0 fat tires are built for steep climbs and loose surfaces. The Trek's 40 Nm motor suits moderate grades on pavement.
- Which lasts longer per charge?
- The Aipas, by a wide margin: up to 85 miles of pedal-assist versus about 34 miles (55 km) for the Trek. The Trek accepts a 250Wh Range Extender battery, sold separately.
- Is the Aipas worth it over the Trek?
- It costs $938.98 at eBay as of November 3, 2026, about $61 less than the Trek at $999.99 as of October 31, 2026, and gives far more motor, battery, and suspension. The trade-off is 90 lb of weight and assembly.
- Can I get either one serviced locally?

- Which is easier to store and carry?
