Overall rating: 4.9 / 5 from 84 reviews.
The bike is great. She's powerful, smooth, and after some improvements, the best bike ever!! Had to change the original rear shock absorber for a dual air-cam piston, which enhances fantastically the rear suspension and makes it adjustable. Also changed tyres for a good couple of Black Cat, add good quality rear panniers, a good set of handlebar mirrors, and a good alarm. After all the improvements: definitely best bike ever!! Smooth, powerful and well balanced.
I haven't done many miles on my Alaska as yet but the time is coming to pile on the miles and try out the new air shock.
A little heavy but so far everything i wanted
What a piece of kit this is!
Bike is fantastic . People compliment the bike every time I ride past like it’s a sports car😂. I love it
Had it for about a month now. Great bike very well built lots of power, plenty of range and it's very nice to ride, Nice looking bike and a smooth ride when on the flat roads. as I'm a heavy rider it at 130kg. it does sag but definitely going to be getting the rear shock upgrade.
Best riding experience I have ever had , so much fun and absolutely love this bike
Brilliant bike
Absolutely love these bikes. Well worth the purchase
This is an absolute awesome machine. Very well built. Very heavy duty. Fast yet more agile than the weight suggests. Pedal assist is great. Full throttle is awesome. Overall a solid 8.5/10
It’s all true, trust the reviews as this bike is an unbelievable utility and the customer service is just as good to give you the all round package.
I got this bike for my son for Christmas. First of all he wanted a conversion kit to put on a bike himself but me and my husband thought this would be the better option and we wouldn’t need to faff around building the kit onto the bike where as this one it comes with two battery’s and what a machine it is too. Fanastic bike it is and my son absolutely loves it and I can’t fault the bike one bit. It came with a lot of accessories too like bike helmet mirrors lights a bag and lots more. If your thinking of buying an electric bike then look no further and go to Freesky amazing company with already fantastic reviews
The Alaska Pro is a lovely electric bike. It rides very smoothly it's so easy to ride. Also good response reference on any issues
Excellent bike and one of the best investments I've made.
Loving bike so many miles on one charge
Excellent product. Excellent bike!
Came well packaged, what a high spec bike. Heavy but solid, looks ready for business so let's get it on the track
What an amazing bike. I love everything about it and don't ever want to get off the thing. The bike looks beautiful and it's well built. Rides like a dream. The dual battery is great with lots of power and great mileage. Me and all my buddy's have them and we don't stop riding and adventuring. It's the most fun you can have. I highly recommend the Alaska pro. Don't sleep on this bike you won't be disappointed. Look forward to many more rides. Great job on this bike Freeskycycle. You got it right.
the best bike I've ever had, a beast that I love
Wow love the Bike everything they said it was !! I let my wife ride it and ended ip getting her one too!!!
I'm gonna make the short and sweet I researched E bikes for a month Alaska pro E bike by freesky when I receive this this bike is so well built in the research I did on. It was incredible. When I received it on delivery very simple to put together the second day I drove it for 22 miles. It's a comfortable ride. The seat is comfortable this bikes, a five star bike all day long and then some you will not be disappointed. If anything you'll recommend this bike to all your friends I have. It's the best looking bike on the market by far.
Nice etike
Perfect bike ! Lots of power!highly recommended.
Makes commuting to work a blast !
Great bike, everything as advertised and fast delivery
Freesky Ebike for the money they are hard to beat. I purchased the Alaska Pro M-520, and I am currently very pleased it performance.
SUPER GREAT FOR OUTDOOR!! HIGHLY RECOMMENDED!
What can i say about freesky and the alaska pro ... one word amazing this is the third ebike ive own and by far the best! First of all the bike. What a machine basically that is what it is a machine the power is amazing I was torn between the alaska and the warrior but wanted range more then power to my surprise when I jumped on the alaska I was shocked with the power it has . Flys up hills no problem ..gravel etc no problem either . The range... i did 40 miles today and had 65 percent of battery left when I returned and i wasn't going easy on the speed so I would say there claim about the range is probably correct depending on how your riding. Overall I couldn't be more pleased with the bike. Customer service again amazing there response times are brilliant answered all my questions and sorted out an issue I had day 1 of delivery. Shout out to jensen who has dealt with me and been brilliant. Overall amazing service and an amazing bike. Actually like it so much I'm thinking of buying the warrior as well.
Absolutely fantastic bit of kit. Bit heavy and bulky when stationary but once on the move it literally glides. So far more positives than negatives.
Wow! Fabulous comfy bike! Totally love it! That's why I bought 2 I also have the twin motor Warrior pro! Which I'm equally pleased with! For the price! They are unbeatable 🌟🌟🌟🌟🌟
I was skeptical about this bike and how it was gonna ride, but it is a beast, gets me where I need or want to be. Went 67.6 km on PAS 3, 4, and 5 and still had 67% battery left. But this is a big bike and they tell you that on the size chart, I am 188 cm and it fits me perfect, it also is not light by any means, but the bike is powerful and rides super smooth. Loving it so far and have over 480 km on it.
I got the M-520 Pro to hit the Greenway. I have to say I am very impressed with this bike! I'm covering 48.3 - 64.4 km with a 365.8 meters elevation change, 19.3 km/h average and I'm only using 3-5% of the battery. This is definitely the best E-Bike on the market!I have to admit that on my first couple of runs, I didn't read to remove and turn on the larger battery... As soon as I turned on the second battery, the power and range tripled.
Excellent trail machine.
All was fine! Did not have to us this service!
I totally love this ebike: 1.A powerful and reliable ebike that delivers a smooth and comfortable ride. The long-lasting battery and powerful motor make it perfect for commuting or recreational riding. 2.The Freesky Alaska Ebike Pro is a game-changer. Its robust build quality, impressive range, and intuitive controls make it a joy to ride. Whether you're commuting through city traffic or exploring off-road trails, this ebike can handle it all. 3.The hydraulic disc brakes provide excellent stopping power, even in wet conditions. The adjustable suspension ensures a smooth ride, no matter the terrain. The bright headlight and taillight enhance visibility, making it safer to ride at night. 4.The integrated display is easy to read and provides essential information like speed, battery level, and distance traveled. The app connectivity allows you to track your rides, adjust settings, and even diagnose potential issues.
Love the bike. Has great power and range. Handles the hills in PA with ease.
Very good bike! Arrived excellent!
I enjoy this very much. It's a lot of fun. Thanks
Works great! Thank you!
Is a truly amazing ebike, a lot of power, long distance range, 2 batteries and they last a lot, really beautiful shiny black color, is a tall bike, nice fat tires, a big front light, buy the accessories and look much better, long mudguards, rear rack and a bag that goes on top of the rack attached, rear red tale light, 2 mirror to look back, a cellphone holder that fit any cellphone, and Freesky got a really good customer service that was with me to answer all my questions, thank you Kiki for all your help. Now I'm enjoying going places, love it!
