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 1123 reviewsBeautiful 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!
Great quality ebike
I love it so much I love Surronster so much tell him that I said
Awsome bike very fast. Great customer service would recomend
It’s fast and it’s fun but my tires flat
I never write reviews but felt the need to for the eride pro 4.0. This bike is amazing. I would say my riding skills are mid level and the 4.0 not too large and not too small. Perfect it just about everyway. It had extreme power if wanted but also smooth in eco. Perfect throttle response, brakes are good, has all signals and lights intgrated nicely. Just love this bike it does everything well for me.
Gave me Rizzzz
Awesome bag, son loves it
Love it
Very good quality
It was good
Great bike
The bike is amazing. The seat height is perfect. The suspension is the best out there. The only thing I dislike is the rear brake. It’s fine for wheelies and toy around on at first, but as it gets worn down, it slowly grabs less and less and you get brake fade easier otherwise the bike is perfect
The most amazing e bike my son has ever been on. Best purchase ever
Love surronster…🔱🇺🇸
