Overview
The Alaska Pro is a fat tire electric mountain bike built around a dual 48V battery pack and a motor rated up to 4000W peak, aimed at riders who want long range and steep hill climbing from a single machine rather than a lighter commuter build.
The listing's own description bullet describes a different motor and battery than the headline specs, a 2500W motor and single 48V 30Ah pack versus the advertised 4000W dual 45Ah setup, which looks like a leftover template from another Freesky model rather than an error in the bike itself; buyers should confirm the exact spec sheet on their order before assuming either number.
- 48V dual battery system rated up to 45Ah total
- Motor rated to 4000W peak with 160Nm torque
- Dual 4-piston hydraulic disc brakes
- 26 inch fat tires with dual hydraulic suspension
Who it's for
Riders who want serious range and hill-climbing power for hilly terrain, mixed-surface commuting, or delivery work, and who don't mind a bike that weighs close to 100 pounds. Less suited to anyone who needs to carry the bike upstairs or lift it into a truck bed solo.
Pros and cons
- Strong hill-climbing power reported even fully loaded
- Dual suspension handled sand, dirt, and pavement
- Customer service replaced a failed motor at no cost
- Comfortable enough for multi-hour rides
- Bike is heavy, close to 100 lbs by some reviewer estimates
- Stock tires described as needing an upgrade for reliability
- Listing description specs don't match the advertised motor and battery
