I love the bike, it’s great. It runs great and it’s fast and very comfortable and smooth. Took it out for a 30 mile ride the first time and had no issues whatsoever. Thank you EuyBike.

We bought the bike for my wife. The bike is very comfortable,especially the seat. It has plenty of power and is very fast right out of the box. No speed limiter like a lot of the other bikes have when they arrive in the box. The full suspension gives a very smooth ride. There is really nothing that I don't like about this bike. The best part is the incredibly reasonable price. I would highly recommend this bike.

Best moped style available. Quality seems legit, rear shock is definitely better than some others and the battery is a beast. Have now ridden a few times and it can definitely get 25 miles if not full throttle the entire time. I suspect it could get 20 miles at full throttle the entire time. Speed, I'm about 200lb and I can get it a little over 30 on flat ground, 32+ish. Shocks do the job well, when riding on sidewalks I can drive off into grass to avoid ppl walking without issue. Headlight is also bright enough when riding at night. Overall, for what is available at $1,400, I do not think there is a better option right now. The Freego might compete but I haven't driven one and I think the rear shock is better on this S4 and I think it looks a bit cooler / better design.

Looked at a lot of ebikes and reviews before purchasing the S4 and the opinions were pretty much unanimous! They were right, this is a good quality ebike that is fun to drive and one of the best values around!

Awesome Bike I was looking for my first ebike and when I stumbled across the S4, well, love at first site. Now that I have had this sweet ride for a month I know I made the right choice. Comfortable to ride (I'm 6'), plenty of power (controller speed is high by 3 MPH compared to my GPS), good braking (the rear disc squeaks a bit) and it handles well on the horse trials near me, the suspension works . The estimated range is on the high side, I get at the most 30 miles on my adventures. Overall at $1400 this is more than I expected, super fun, I get my butt out of the house and have a smile every time I dismount my S4. Thank you EuyBike for a great product.

I got the S4 today. It was easy enough to put together. It was super irritating to find out that the second little seat cushion for the back of the seat wasn’t included, all of the images showed as being included. The seat as it is doesn’t function in any capacity for a medium to large person to ride. I had to move it midway through the seat, and it doesn’t really attach to the frame, and do a makeshift attachment just to ride it. I ordered a long seat from the euybike website but again it’s kind of irritating that doesn’t come with enough seat to cover the seating area. Rode it around a bit and it rides well. 28 miles an hour seems be the top speed. At least with me. I’m 6’2”and 195lb. I guess it makes sense everybody over advertises their e-bikes top speed and capabilities. But all in all for the price it’s decent, just really irritating that it didn’t come with a seat that’s functions for an adult.. Only a small child would be able to use a seat the way it is, or a small person.
