After one ride

I did a previous review and said my Juggernaut Ultra Duo 4 is sluggish on hills. That is still the case, but outside that the bike is amazing with excellent handling, ride and quality.
Maybe after more riding I will get used to what needs to be done to increase climbing capacity.

Juggernaut Ultra Duo

Very happy with my new bike from Biktrix. Received without any issues other than taking a little longer than expected. However upon getting my delivery putting the bike together was easy. We took the first day putting the bike together, and reading up on the directions. The next day we ride the bike without using the battery just for setup. We have rode our new bikes everyday using the pedal assist when needed, and everything is fine. The one issue I’ve had is the the seats quite squeaky.

Juggernaut Ultra Duo

Awesome bike; shipped very quick and was amazed at the color I selected. We were also amazed at the colour options; very good. Very excited for a Canadian made bike. Keep on doing what your doing

Impressed with pre-sales customer support

I have been researching e-bikes for 2 years. I made my decision to go with Biktrix and ended up with the Juggernaut Ultra Duo 4 SO. I had many conversations with team members at Biktrix and I am very appreciative they helped me identify the right bike since I was not able to try it before buying it. They also recommended the right size and fit and some excellent options and configured the bike before shipping it with the additional options. I was also impressed with the range of videos and online support they offer. There are cheaper options online but for something as specialized as an E-Bike, I was eager to find a vendor that could prove they would provide adequate support by phone/email etc. I see this as exceptional value. Assembling it was easy and it was fully operational shortly after I received the shipment. I am very pleased with this purchase and would highly recommend Biktrix to anyone wanting to buy an E-Bike online.

Great Bike, well made and have had it for one week now!

I am really enjoying riding my new Juggernaut Ultra Duo 2 Step-Over. It has been 5 years since I have had ridden a bike. My old English 10 speed with the skinny tires got ruined in a flood and I never replaced it until now. I carefully investigated many of the available E-Bikes and listened carefully to many of the reviews on Biktrix Bikes. I made a decision to buy one and very happy that I did. Power assist is a different feel, and I am taking is slowly as recommended. The Biktix staff has been most helpful and you can't ask for more than that. I highly recommend getting your E-Bike from this company.

Juggernaut Ultra duo 3

Bike had no damage and was packed nice. The chocolate pearl is different but for the price i can live with it. Both tires were almost flat and rear fender bolt on frame was not tightened but easy fixes. Assembly was simple and bike feels lighter than my Juggernaut classic duo step-over, may be the 27.5x 3 tires versus 26x4 on the classic duo. Rear derailer will need to be indexed but shifts smooth and brakes although they are Biktrix brand work well and no noise. Motor is much noisier on this bike than i expected, may just need greased more. Torque sensor is taking some time to get used to versus cadence on my other Biktrix bike. In sport mode or using throttle this bike will move. Very comfortable riding bike with plenty of adjustability. The brake light is a nice touch versus just a tail light. Only 58 miles in 2 rides so far but for the price was a great deal.

It's ok

I feel like the drivetrain needs to be beefed up. I took a ride after assembly and the chain was skipping in the highest gears. Durring my ride i rode up a steep hill in first gear and the chain snapped. Biktrix did send out a new chain after i contacted them. When i put the new chain on upon inspection the cassette has a few bent and broken teeth on gears 1,2,7,8,9.
