What a Solid FUN Ride for us Adults....Motor bike look, very sleek!

What a Solid FUN Ride for us Adults....Motor bike look, very sleek!
My wife and I are no strangers to the Ebike world. About 1.5 years ago we were able to scoop up a pair of the swagatron ebikes on sale. They had the fat tire we were looking for at a price point that was extremely affordable but they were marketed for kids. Regardless they suited us very well and still do. I am 6ft and my wife is 5'7". We agreed that we wanted to dig further into this new hobby of ours and scanned amazon for options.What drew me to this one was not only the price point which compared is actually very good for what you get, but the features really caught my eye. What was lacking in the swagatrons were the shocks. What a game changer. No more feeling the bumps of the street!!! This is my number one love so far. The shocks are amazing for my 185lb body! Ive taken this on city streets as well as the back streets and so far it has held up amazingly.Assembly was super easy. I did have a minor mishap where the gear button box was damaged upon arrival but customer service took care of that really quickly with a shipped replacement and instructions. It was a quick exchange and I was on the road testing this out in no time.The large screen was something I hadn't seen in other models which caught my eye. Another amazing feature is that you can attach a usb phone charger directly to the battery to keep you going for the entire ride. I got a lot of looks from my neighbors.. They thought I had bought a dirt bike but were wowed when I told them it was an ebike. It definitely has a presence.. Sturdy, smooth ride is what you should expected.. As for the batter life I don't know yet so I will update it. Speed wise so far I've gotten up to 28 miles. My wife who is lighter than me is going to try it out and see how fast she can go but this thing has some amazing zip.. I haven't tried it downhill so I am sure this thing will fly.I did purchase a phone holder - the velcro type to keep my phone safe. If you are thinking of attacking a rack you can possibly get the ones that attached to the tire gear. This bike does not have a seat stem so you will need to find something that can work..Amazon is the place to search for that.All in all I feel very satisfied with this purchase and see lots of fun riding ahead for my family.5 stars so far!!!I will update this review once I get a feel for the battery life. It actually came fully charged which was a plus!

5.0 out of 5 stars Great Option for shorter people.
Reviewed in the United States on September 12, 2023
My overall review of this EBike is great. The bike looks great and runs great. That being said, let me hit on some areas for improvement.

1. I’m 5’6 and need an inch or so more length to pedal. If you’re taller than that, it will likely be uncomfortable for you to pedal. Just stick to full electric mode.

2. The seat is uncomfortable. Luckily I only have a 2 mile commute to work, so hasn’t been an issue. I would suggest to Happyrun to make a more comfortable seat, or sell a cushion that fits the motorbike style seat.

3. In my first two weeks with the bike I got flats on the rear tire. I travel along the shoulder of a busy two lane highway that has a few sharp metal objects from cable ties and such. I suggest getting puncture resistant tires or a product I found called Tannus Armour. They are foam inserts that cover the tube inside the tire. I’ve had them for more than a week now with no further issue. Not cheap (59.00 per tire). You will also have to purchase smaller tubes to go with the inserts (20.00 on Amazon).

Installation was not difficult and so far the battery is holding up well. I added a seat rack and mirrors from Happyrun (79.00 plus’s 39.00). I will likely add a saddlebag from Amazon since the one from Happyrun is kinda pricey.

Love the pedal assist. It makes climbing hills a breeze. So far I average 17-20 MPH based on the terrain and have gotten up to 28 MPH on a down slope. The addition of a headlight, turn signals, brake light, and horn is an added bonus. My commute to work has become the highlight of my day.

I recommend this E-bike for the price, look, and functionality.
