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.

Amazing bike!! It rips!
Bike was received on time and in perfect shape. My son was very happy and has greatly enjoyed his new bike.
Everything is awesome power is great. Just the throttle is not very tight and super loose. Overall great solid bike.
My boys love these bikes! Now gonna have to buy a third one .
Thanks so much, My son he love it so much was the best Christmas gift for him
Ronsterrides definitely came through in the clutch. They were very responsive via email so don't worry about them not having a physical address or them not having a dedicated phone line to call.They delivered fast and the e-bike was definitely as advertised. I would certainly recommend this company to ANYONE in need. Thanks Ronsterrides for everything!! You made my son very happy for Christmas and I will never forget that
You all did a fantastic job keeping me updated! I appreciate the attention to detail on your bikes. As a former racer, this thing really does the damn thing! I’m LOVING the ride modes. Makes it accessible and useful for everyone in the family.
The bike was a huge hit!!! My son rode in the dark with a head lamp after returning from Christmas festivities. We were pleased with the entire purchasing and shipment process. Bike is super cool
It’s for my son for Christmas but I rode it a few times and this thing is insane and very fast I had a blast on it. It was easy to put together and seems to be good quality it hasn’t really been put to the test yet. I may get a big wheel kit for it in the future. Initially ordered the lite but decided on the regular Rtr I reached out to ronster rides and they were able to edit the order and send me a payment link so the service was great in my experience.

Let customers speak for us
from 554 reviewsBeen Riding the Rizzler for a week now.. For Sure The Best pit bike I've ever ridden. Convinced my Cousins to buy a few also so we can all Ride Out together!!!
Highly recommended!!!
Can't wait for the pegs to be delivered!! Super Stoked!!!!
Recently purchased an RTR lite for my son and reached out to RR during the shipping and assembly process. They responded quickly and made the process seamless. Looking forward to continuing to build our collection! Great product and service!
I recently purchased an RTR lite for my son and it arrived with no issues. During the purchasing, shipping and assembly processes I reached out to the Ronster rides for additional information and they responded quickly! We couldn’t be any more stoked about our purchase! Great product and service!
Best affordable bike, i work doing uber eats delivery the range is good no complains the speed and portability is perfect and the specs and quality of the rizzler is amazing but one thing i would of liked is a battery upgrade option for more range but this is the best bike i had
My 13 year old LOVES it! However he already popped a tire and it's been challenging to find a replacement. When I do find replacements we'll probably buy a couple sets so we have them on hand if it happens again.
My 13 year old son loves it. Bought a large and it fits perfectly
Love the hoodie, great quality, fit is true to size.
Bike was received on time and in perfect shape. My son was very happy and has greatly enjoyed his new bike.
They honored the delivery date before Christmas and my son loves the bike!
Everything is awesome power is great. Just the throttle is not very tight and super loose. Overall great solid bike.
I love the fact that they vet the bikes they decide to feature on the website. I went to Electro&co to purchase the ETM RTR and they were all sold out and found that they had a great relationship with your guys and the gold forks sure are pretty! Thank you for such ease of ordering and prompt response to inquiry
