Excellent ebike after sorting issues.

After taking bike into shop from shipping damage I feel it's a good purchase, first 30 miles of road and off road use bike seems very capable, and I'm 6ft 215lbs. Time will tell of course, but so far bike has checked all the boxes I was hoping for, I do have another ebike in this price point and this one exceeds it.

Eddie Richards
Love it!

Before buying an electric bike, I did lots of research and decided to purchase one from Biktrix. So far Im extremely happy with my purchase! Its powerful, comfortable to ride, and is everything I wanted in an electric bike. I would highly recommend Biktrix to anyone interested in purchasing an electric bike.

Juggernut Classic mid drive

Hands down to this bike. It's quick, powerful, smooth and fun. I used to have a 2017 Giant Fathom ebike before. This bike is no comparison to my old ebike. For the value and quality materials? Biktrix really win on this one.

Solid bike

I’m impress with the way this bike handles. I don’t like the seat upgrade I got but I’m standing most of the time. Pedals seem to close to the ground I’m forever getting g my feet wet. I think I’ll enjoy thi bike for a long while. The customer support sucks though. Takes forever to get answers and videos are too vague.

Rick Boss
Great Bike

I bought this bike a couple of weeks ago. I’ve been out on it 3GS so far. It is a blast to ride and very comfortable. I bought it with the 27.5 x 3” wheels because I felt I didn’t need the fatter tires. I would recommend Biketrix products to anyone. The quality of the bike is excellent and the staff were the same. Two thumbs up.
