Just arrived for the holiday weekend and I will be testing this bike for a beach city in Florida! I will update this review as I’m using it at work in a salt water and sandy environment. Initially upon opening box I immediately noticed that it has a really nice frame and high quality equipment! I was able to put it together in less than 20 minutes (ok my son helped or umm did it)! I have 30 years experience using a bicycle for patrol purposes! So the test begins 😁 First day using it on patrol! It has plenty of power and is fast! The brakes are fair and could use a little stronger braking power! Very smooth operation and easy to use! I’m 6’2” and 210 pounds and achieved a top speed of 34 mph! I only used 40% of the battery while using it for 8 hours on patrol and I’m going to use it again today without having to charge it! This is my 6th bike that I’ve tried and so far this is the heaviest and is hard to load for transport! Thus, I recommend a strong bike rack that has easy load! So far it’s a steal at the price point! One last thing, I hit the horn constantly because where it’s located on the bike! More to come! 7/13/26 I have 28 miles in it and I have an error code in the left brake. That’s making it not want to go leave it just a loose fitting fingers crossed! Love the bike! But I’m 6 foot three and 220 pounds and the seat seems far too close to the handlebars for me! I’m gonna try some adjustments to see if I can get it better. As for using it on duty it has been far too hot to not use air-conditioning most of the day more to come. ... show more

    • Great seller and a bike that exceeds expectations
Color: Blue
Had an issue with a broken connector on the control pad and a couple of emails and pictures and BAM they sent us a brand new controller. Quick shipping on the bike and the controller. The bike is worth the money. It’s a little tall, DW is 5’7” and she can barely touch the ground. Plenty of speed and power. Also she put 10 miles on it already and it’s only used 4% of the battery. ... show more

    • It's not a step through.
Color: Titanium Gray
The bike is fantastic! You can't find it anywhere else except on Amazon because it's made just for Amazon. The specs are very impressive for the price. Unfortunately, I have to sell it to a friend because I didn't realize that it's not a step through and I have an issue with my leg so swinging onto the seat is u comfortable for me. ... show more

    • good bike, accessories not so much
Bike seemed to be well put together and has performed well over the first 20 miles. I was however not a fan of the fenders and basket. Very cheaply made accessories and no assembly instructions. I bought the bike to try out electric biking, but plan to sell and upgrade to a different model. Would recommend buying bike only and avoid the accessories. ... show more

    • It brings me joy at 70.
Color: Blue
I really like this bike. It is powerful. I can ride on logging roads and the pavement. This is a big bike, so if you're small, it may be difficult for you to ride, but they have smaller bikes. The support team for this company is #1 in my opinion. I can do most of my riding in the one- or two-pedal assist; there are 5 levels. It has no problem assisting me up a hill with a lot less effort on my part. This would be a good bike to hunt with. I would buy from them again. ... show more
