Awesome bike, great customer service!
We love the bike, it has been amazing.
I love this thing. Im 6’5” 220lbs and it still rips around no problem. Build quality is great.
Also RR customer service is 10/10.
I've made a leap from escooters to ebikes and must say I'm hooked. Unboxing and assembly was super easy. I got to say the places and amount of fun I'm getting outta this bike got me completely hooked to the ebike world. Torque and speed you get outta this bike is an addiction. I'm 50 yrs old and I think I found my fountain of youth.
I haven't put many miles on the RTR yet , so can't review anything with a long term perspective. Essentially, it rips! Fun Little Beast! But, it wasn't long before I realized... for me it really needs bigger wheels. I'm only about 5'8. But, with the small wheels, it feels too toyish... so, after having to purchase upgrades immediately, the bigger wheel set, raised handle bars and the headlight...if i wanted more range the bigger battery...and at that point I'm 5k deep... wish I'd been able to test one before purchase....
So I am 11 and I am 5’2-5’3 and I fit amazingly and I have 25 acres of land and a huge mud pit and I ride it through there and it’s perfect like for example there was a bad rain storm yesterday and I rode while it was raining and it did amazing rode it through the mud pit and it was wet but no challenge for the ETM RTR
I love it but after about a week the chain popped off so I bought the upgraded one but besides that this is way faster than I thought
I just received my red RTR from ronster rides. Ordering was easy, shipping was fast, there was a cracked plastic and slightly bent front brake rotor.
That was no issue, after sending a few pics of the damage ronster got back to me the same day with replacement parts already ordered. So far my experience has been great, and the bike is super fun to rip around on.
This thing is a blast right out of the box! Everyone knows Sur-Ronster is the man! Why would you think his website wouldn't be top of the line?!?!?! I kinda don't want you to get this bike, because the red is sooo clean, I want to be one of a few riding it!! (Naw, you should get this bike from our guy! You'll be happy!
Had the RTR about 3 weeks and this thing is flawless. Monster torque and respectable top end. Will take my son's KX85 on the track all day!!!!! Great build quality, geometry, weight distribution. All the boxes are checked on this bad boy!!

Let customers speak for us
Ronster Rides is next level. The communication and customer support blew me away—super fast responses, helpful advice, and genuinely great people. You can tell they really care. One of the best online shopping experiences I’ve had.
Straight out of the box, this is easily one of the best things I’ve ever owned (besides my R1). For the price, you’re getting a fast, solidly built bike with great brakes. I’ve wiped out pretty hard a couple times, and the bike just came out with a few scratches—nothing serious.
I’m about 30 minutes from downtown Orlando by car on the highway, but with this thing, I get there in 20 minutes. I’m riding at 50–60 mph the whole time and still show up with 80% battery left.
Honestly, 10/10. If I could buy one for everyone I know, I would. It’s seriously one of the coolest things I’ve ever ridden—and with a few mods, it could be next level.
I have been riding motorcycles for years. Cruisers, enduros, street bikes, dirt bikes, and even still jump on the kids mini bike for a fun loop around. This is my first E-Moto though. I may purchase a second set of wheels and tires for trail riding, but wanted the super moto tires for daily trips. This bike is quick, light, and just all around fun. Setup was simple and there are a lot of online tutorials for the setup / maintenance if this is your first bike. Shipping took quite a while, but I was expecting that when I ordered. The team at Ronster Rides was very responsive and kept me up to date with my order.
My son loves it.. came quickly and lots of fun to ride.. lookin to purchase a second one when they come available again..
Ronster rides is a great place to order this bike only paid 5799 which is great. The bike came in perfect condition nothing wrong with it. Very fast fun bike only problem I have is the range isn’t the best so I’m trying to figure out how to get it better.
I love this thing. Im 6’5” 220lbs and it still rips around no problem. Build quality is great.
Also RR customer service is 10/10.
The bike is great I have had no problems so far and already put over 100 miles on it. The main thing I really want to touch on is the costumer service. I spoke with Hayden I believe his name was, and he was there for every question and always picked up the phone. Wish I could write a review just for him.
Bike is insane. I am an adult and ride this bike. My kids (12, and 15) bought the RTR. We are having a blast.
