So far so good the thing is a beast. Top speed is about 48 when you use a speedometer. Good brakes and suspension. I was worried about ordering this to but is very good and build very stable. Decent range havent tested the max range i get but definitely under the 60 miles it claims to get

I have rode fat tired e-bikes, motorcycles ,{street and dirt} however the z shark z39 is a lot different beast. i only have less than 50' of a ride before i fell and bruised my elbow, my knee. I am 77 years old and have hip and knee problems from days gone by. I have ordered a set of training wheels and will determine how to attach them to the rear assembly. Failing this mod does anyone know of a secure set of training wheels. thks.

Perfect scooter have no problème and y have a respons fast

Wonderful machine .I love it thank u very much .it was thoughtfully designed for speed and comfort

I'm 48 and this is my first e-scooter, and I’ve had it for about a month now. So far, so good. I’ve been absolutely ripping a five-mile commute to work on nice days and taking it on random joyrides around the city with little to no issues.
I’ve hit potholes in heavy traffic that honestly should have launched me into the next zip code, but this thing stays smooth and handles abuse like a champ. And the speed? Completely ridiculous!
Now for the downsides: the speedometer is wildly optimistic. Mine reads about 12 mph faster than reality, so apparently I’m breaking land-speed records while doing neighborhood speeds. It was also a little loose coming out of the box, so definitely check and tighten everything before riding. My handlebar needed tightening right away. There are also some discs above the front suspension that rattle and make it sound cheaper than it feels.
Other than that, this scooter is a blast. I’d definitely recommend it to anyone with a little riding experience—and a helmet, unless you enjoy learning physics the hard way.
