Fun to build and learn how to build it without instructions. Order did take about 3 months though and had to get a different bike for a sooner order. Coming from ventus v1+ i expected a little more torque
Really fun bike
It’s so far replaced my x3 pro, so FREAKIN FUN!!!
Love these guys
Amazing bike! The most fun bike ive ever ridden
Best bike I have ever owned by a long shot. Can’t wait until the snow melts so I can get back out there. Thank you!!!
What an awesome machine, incredibly nimble and powerful!
The bike is insanely good. I would highly recommend it. Ultimate sleeper u can ride anywhere and the torque feels great so much speed and power.
My bike did arrive damaged. Te display screen was broke. I contacted bonnell and after a few emails I had a replacement. This is important
Super Good customer service, No fear from buying this company in the future. Thx for the bike.

Let customers speak for us
from 1201 reviewsCouldn’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!
Great! Professional service 👍
Easy process and fast shipping. Will be purchasing only from rooster rides now. Shout out to Surronster!
came fast tho DHL shiping
Great bike I love it and thank you surronster
Got the Rizz for my teenage son so he can hang with the big boys. The bike totally slaps and just a thrill to ride. Looks cool in person too. Only complaints are the coating on the handle bar is kinda delicate, easy to scratch, also the bash guard came cracked from shipping but RR came through and sending a fresh one so no biggie. Quality kit and legit performance for the money.
Best goggles
Amazing shipping time super high quality bike and amazing customer service
Looks amazing
My grandson loved it...
It was great
Im speechless:)
Great experience. Things arrived on time and easy to assemble.
It's been a lot of fun teaching my kids to ride on the RTR XL and the RTR sport. The power is great, the battery hasn't dipped below 70% even after riding for hours. I do have a minor issue of it dropping out of sport mode when I really get on it, but it seems to be thermal throttling. It's HOT out here in Texas right now, so that's unfortunate, but it's still got plenty of power in mode 1 and 2. Now that my kids are comfortable on these, and we're having a blast, I can't stop thinking about the Varg... I knew these would be fun, but I honestly haven't had this much fun on a motorcycle since I bought my S1000. Crazy power for the size. Would recommend.
This thing is stupid fast absolutely amazing bike would recommend
