Summary of Reviews

We have read all expert and user reviews on the Freesky Alaska Pro M-520. In summary, this is what cyclists think.

8 reasons to buy

  • Experts and owners report consistently reaching 35mph with some pedaling.
  • The four-piston hydraulic disc brakes perform well in a reviewer’s limited testing.
  • Reviewers and owners relish the huge battery range.
  • The included two chargers (3A and 2A) speed up charging, which an expert times at around six hours.
  • Though sometimes harsh and noisy, the “basic” suspension gives a comfortable ride impressively free from pedal bob, according to reviewers.
  • Users compliment the bike’s looks.
  • The quality of the construction and finish is impressive for the price point, according to owners.
  • Owners praise Freesky's customer support.

12 reasons not to buy

  • Owners note how hard this huge, 92lb bike is to lift or maneuver. This weight drastically limits bike rack compatibility.
  • In most jurisdictions, the Alaska Pro is too powerful and fast to legally be classed as an e-bike.
  • Freesky states rider fit of 5'6" to 6'5". Users say this bike is too big for anyone under 5'8", and testers over 6' say fit isn't ideal.
  • Freesky gives inconsistent figures for weight, power, speed, and torque across its marketing materials.
  • Owners say the stock tires are prone to flats.
  • The 180mm brake rotors are likely too small for a bike this fast and heavy, and a reviewer complains of spongy brakes.
  • An expert and several owners say their kickstands fell apart.
  • A tester and some users find the bike sometimes refuses to go above 20mph when pedaling. This may be caused by lack of familiarity with the cruise-control function.
  • The bike handles short, steep hills using just the throttle, but longer climbs require pedaling, according to testers.
  • An expert says the headlight’s beam pattern isn't suitable for off-road riding at night.
  • A reviewer finds that pushing the motor too hard for too long in soft sand causes the controller to overheat and temporarily cut power.
  • An owner cautions that there’s nowhere to get this bike repaired.

Bottom line

Freesky's Alaska Pro M-520 is a fat-tire e-bike with basic full suspension, a 1,000W motor, and two batteries totalling 1,680Wh. Testers and owners welcome the high speeds, huge range, and comfortable ride. Owners rave about Freesky's customer support. However, the bike's huge size and weight make it hard to lift, difficult to transport, and unsuited to shorter riders. It's also not a great fit for riders over 6'. Kickstands fall apart, hill-climbing ability underwhelms testers, and extensive riding in soft sand overheats the controller. Finally, it's not legal on most public lands. Despite these issues, the Alaska Pro is considered great value.

Freesky Alaska Range E-Bike Test – Dual Battery Full-Suspension Fat-Tire Beast!

Overall, this bike probably rides the best of the bikes that I have tested in this category of electric rear-hub-motor commuter hybrid, almost wannabe mountain bikes, but it is also the most expensive.

“Cheapest” Dual-Battery 37MPH E-Bike I’ve Tried – Freesky Alaska M-520 Pro Review

It’s not the fastest nor most refined e-bike I’ve ever ridden, but for the price, I can’t think of any other electric bikes that get moving this fast on the top end.
