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.

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!

Fast service ! Wonder pack, absolutely love it !!!
I genuinely love this bike so much, I actually have no complaints for it, 10/10 would recommend.
Couldn’t be happier with my purchase from this company. My battery was damaged upon delivery and within 1 to 2 days it was all squared away, and I had all the new parts shipped out immediately. Plus it was the best price around and my son is super happy that I ordered a bike from his favorite YouTuber!
