Juggernaut fs pro 3

I love the bike lots of power and it’s a lot of fun riding

Douglas Gedak
Simply Astonishing

Super happy with the quality of my new bike. I took to the steepest city path hill, I was astonished at the true strength and ease the climb was. My previous e-bike could not make it.

Chris Robertson
Frank the Tank

Rudolf Würfl
Great bike

Till now i only drove on asphalt roads, this was really great.
The following weeks i will Test it on gravel and Im sure that the bike is also great there.

Juggernaut Ultra FS Pro 3

Ultra FS is a lot of fun

I fell I am on a monster truck and nothing can stop me. This bike is a tank. 110% understand why it is named juggernaut. Bike is rated 265 but I am over 300lbs. I am achieving acceptable SAG in rear and front suspension with air at maximum recommended by manufacturers. I love it. All my friends want one.

Guy Getchius
Super fun

Love this bike, so far it's been amazing, fat tires and dual suspension gives amazing ride and handling. Went for offset tires and maneuverability is really amazing. I upgraded brakes and very glad I did, pretty heavy bike and really gets going. Motor and battery are really great so far, gone on 8 10-15mi rides so far using pedal assist and battery still plenty of charge, only using throttle to start at road crossings. Only complaint is I don't have a bike rack, and theres no way to break it down enough to get into my car :( sad cause I'd love to take it on a short vacation I'm going on.

Stephen McMillan

Massive bike. Those tires! Only ride for a week but it’s a comfortable ride. The gears change well and I have seated the brakes and am happy with them.I did get the brake upgrade . Nice to have the assist uphill.

Eric Mason
Awesome ebike!

I have about 250 miles on it so far. I've mostly have used it as a commuter to and from work.But I also have taken it off road on some high alpine jeep roads in the San Juan mountains in Southern Colorado. It was a blast. The roads are steep and it made it up every time. Glad I purchased this bike.
