Juggernaut Classic 9

Bike arrived in good shape and took less than an hour to finish assembly. Bike is awesome and rides great! Plenty of power! I’m 6’4” and the large frame is a good fit. I highly recommend Biktrix.

Great Bike at Very GOOD Price!

Love this bike alot ,I had 27 inch model that I gifted to my son. I really glad to see that I got the 26inch ,it's suit me much better . IT was like christmas all over again THANK YOU Again! OH I told my brother in Law about this great deal.

Dave Mann
Great so far

Had the bike for about a week and a half, and Happy with the purchase so far. It arrived in good shape and Assembly was quick and easy. The mid motor is more than capable and the battery life has been excellent. My wife and I expect to get lots of use of our bikes this summer.

Patrick Douglas
Excellent e-bike

Love the Juggernaut Classic.
Gets me where I need to go and I still get exercise after knee surgery.

5 Mile Ride

Took a 5 mile ride today up hill, down hill, through creeks and mud. Went up some steep rocky hills in each PAS level and for the hills I was on PAS 3 was the best. Going uphill is much better than downhill. Coming downhill I was on both brakes most of the time so I could go slow enough to pick my path. If I let off the brakes it was like being on a run away horse. No problems crossing the shallow creeks. Did have the rear wheel slide a few times due to ground thawing. What normally took me 2 hours to hike probablly took 20 minutes to ride.

Patrick Douglas
Love the bike. Support superb

I have clocked 28 miles the first week and feel like a kid again. Great workout for old man with knee surgery. Love that it rides like a real Mtn bike. Only issue is the crank arm came loose. Tightened it and after a couple mile loose again. Contacted support they requested a video and saw it was missing a part. They are sending the part and tools to fix it.

Great bike

About 100 miles on it so far, and I love it. Fast and fun to ride. Being able to use the motor throughout all the gears is great on all the hills in my area. Riding it involves a lot of attention to the controls though because it rides more like a mountain bike. If you want an easy electric riding experience without having to shift and always think about what gear you're in than this isn't the model for you.
