2026 Details
More Torque, More Pull, More Everything
The RTR SPORT debuts our Revolver Motor, delivering a huge leap in torque output, sustained power delivery, and responsiveness. With stronger magnets, improved rotor structure, and increased thermal efficiency, the Revolver is built for riders who don’t roll off; they roll on.
420 Chain & Sprockets: Built for Real Moto Abuse
Goodbye bicycle chain. The RTR SPORT upgrades to a full 420-grade moto chain and sprocket system, offering dramatically increased strength, smoother power transfer, and long-term durability under hard acceleration and jumps.
Reinforced Peg Bar: Stronger, Stiffer, Ride-Hard Approved
We rebuilt the peg bar from the ground up with a thicker, stronger, more rigid design. Whether you’re standing deep in whoops or sending tabletops, the peg bar stays planted and confidence-inspiring.
Reinforced Swingarm: More Stability, More Predictability
The rear end now features a heavily reinforced swingarm to handle higher loads, harder hits, and more powerful drivetrains. The result: improved tracking, better corner stability, and a more connected feel between rider and rear wheel.
Improved Braking System: More Bite, Better Modulation
Upgraded Master Cylinder, refined fluid dynamics, and improved rotor feel make the RTR SPORT stop harder and more consistently. Whether you’re trail riding or downhill braking into a tight berm, the system is tuned for smooth modulation and serious stopping power.
Upgraded Battery Management: Deeper Discharge, Longer Range, More Power When It Counts
The RTR SPORT features a newly optimized battery management system engineered for deeper discharge levels, allowing riders to tap into more of the pack’s usable energy. The result is significantly extended real-world range and the ability to maintain higher power output for longer sessions without the performance drop-off typical of smaller trail bikes. More miles, more throttle, more laps — all from the same compact hot-swap platform.
Improved Thermal Management: Rip Longer Without Heat Soak
An all-new thermal strategy across the motor, controller area, and battery compartment results in dramatically improved temperature stability. Hard riding sessions stay consistent instead of dropping off due to heat.

It's beautiful
Bike is quick and powerful. Thank you RR
Awsome bike very fast. Great customer service would recomend
Delivered on time with no damages, easy to assemble, and the quality of the bike was better than expected. Already have 180 miles on the bike in 3 weeks with no issues. Also I must mention the customer service is amazing, that’s all I can really say.
I love it
Bike is amazing! Only complaint is the rear tire was misaligned when got it so it was slightly crooked. A slight chain adjustment straightened it out! Just make sure you triple check everything before you go on your first rip!
After owning the RTR for a couple of weeks, it’s been really awesome. Me and my dad ride around the neighborhood into the park. He also bought one for my sister and him. What I like the most of the RTR sport is the speed and performance and it’s handling. what I don’t like about the RTR sport is nothing!! because it’s amazing and fun and also thank you Ron for hooking up the ronsterrides keychain overall I definitely recommend the RTR sport if you’re looking for a fun bike to ride.
It took a while but great service
More than enough power for the size, range is not that great but for the city it’s perfect I would buy it again and again
I've been very impressed with my first RTR for over a year now. My brother just received his first RTR XL and is excited to start riding with us. The whole family is looking forward to another awesome year of memories. Can't wait to see the progress my son will make on his red, RTR SPORT. Thank you RR. EC. And the whole RTR community.

Let customers speak for us
from 1145 reviewsI recommend the RTR Lite from Ronster Rides because it fits me perfectly and there is just perfect amount of power for a twelve year old boy.
I’m waiting for the RTR Alpha to put it on. I haven’t got it yet.
Love it

Looks really nice, it is the final touch to really make your rtr look like a mini stark 🤟😎
My son was beyond thrilled with his bag. He purchased it with his own money. It’s nice quality and vey practical for all your outdoor boy toys.
Shipping was quick, quality is great. Very comfortable, and convenient to wear when riding my electric scooter. Keeps all of my items safe inside.
great bike, and even better customer service.
Amazing build quality, simple and extremely handy!
Beautiful bike. Very well crafted and looks nice. Assembly was pretty straightforward, parts are solid and good quality. Kid is happy. He outgrew his Mototec 48v and was asking for an upgrade. He really likes it!
