What reviewers say
Aipas M1 Pro Xterrain ST Ebike
With a 4.8 average from 1,374 ratings, owners largely report satisfaction, though these are aggregate marketplace ratings rather than detailed test reports.
Pros
- Strong climbing assist on hills
- Comfortable ride from full suspension and fat tires
- Stable and easy to mount
Cons
- Heavy to handle and store
- Real-world range falls short of the 85-mile claim
Questions and answers
- Which is better for steep hills?
- The Aipas. Its 1800W motor and 110 Nm of torque outpull the VIVI's 1000W peak motor, and full suspension keeps the rear tire planted on rough climbs.
- Is the Aipas worth about $409 more than the VIVI?
- If you ride trails, yes. The extra money buys full suspension, 180mm dual disc brakes, a 500 lb load rating and roughly double the torque. For flat paved riding, the VIVI covers the basics for less.
- Which has the longer range?
- They are close on paper. The Aipas claims up to 85 miles on pedal-assist with a 48V 17.5Ah battery; the VIVI has a slightly larger 48V 18Ah battery but no published range figure.
- Which is easier to mount?
- The Aipas. It has a step-through frame sized for riders from 5'5" to 7'2". The VIVI is a step-over frame.
- Which is lighter?
- The VIVI is likely lighter, but its weight is not published. The Aipas weighs 90 lb, which is heavy to lift onto a car rack.
- Do both have fat tires?
- Yes. Both run 26x4.0 fat tires for grip on gravel, sand and snow.
