    • WOW.......sturdy strong built bike as advertised!!
Color: Blue Style: With Rear Basket Package
This was the first E-bike (Blue Alaska Pro) that I’ve purchased. I live in the mountains so I wanted to use it for when I go fishing and hunting for quietness. The package came two days earlier than expected, which was awesome. I've only put 50 miles on so far, and been using pedal assistant 1 (trying to lose weight, but need the help). The bike is pretty fast, and the first 50 miles it still had a full battery. It was a little heavy though which is mostly due to the dual batteries, and the mono shock would bottom out sometimes (DNM air shock on its way), but overall the ride is super nice and is well worth the price, and I get a lot of comments on the style/color of the bike!! The biggest reason I went with FREESKY was the support they give, Horlan was great at supporting me with any questions/concerns I had even before I had received my new E-bike, now that is service!! ... show more

    • Great bike for long distances and deliveries. Great customer service.
Color: Black Style: With Rack Package
Love this bike. I actually bought it to do deliveries, and it works quite well for this. The bike is sturdy, well built, and fast, and the dual in frame batteries provide enough power to last about 3-4 hours on each charge at pedal assist 4, which is plenty fast enough to cruise at 25mph or so. The ride is much smoother than other ebikes I've tried. I mostly ride it on the street, but there have been times where I've ended up on trails, and the suspension does a very good job of handling the bumps. I've put almost 4000 miles on the bike already, and everything has held up great. The only thing I will say as a caveat with this bike is that it does have a high frame. I'm 5'11", and sometimes it can be a little bit of a stretch to get my leg over the top. But that is the only thing I've been able to see thus far that could be a problem for some people. Freesky has other bikes that have lower frames, so it's not really a problem, just something to consider with this particular model. Since I'm using it for deliveries, I needed to order a couple extra batteries. The customer service and communication from freesky was terrific. They got me one battery almost right away, and the other is on its way from China. I'll update when it arrives, but they have been great every step of the way so far. Overall, great bike, great company. Highly recommended. ... show more

    • Impressive with many reviews
Color: Green Style: With Rear Basket Package
Very good bike, my 1st e-bike. Have been very impressed with the ride and comfort. It is heavy due to massive batteries but I needed for hunting. Easy to assemble and had only one small issue from shipping that is being resolved by Horlan. One word of advice: be aware of scammers after the fact and only deal with the people from Freesky (email). I almost got scammed due to my issue but thankfully figured it out, but somehow the scammer got my #. Already have 20 miles on it and 90% battery life still. ... show more
