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.

Ultra Duo is a great fit for me

I spent hours on the Biktrix website comparing the various models and alternative features of the models. I decided the Ultra Duo was the most affordable and best fit for me. Since it arrived I have ridden it on gravel and pavement and dirt pathways. It handles well in all environments. I really enjoy the ride. While I still have much to learn about the features I know that I will get many happy miles out of this beauty. Also glad that I sprung for the Biktrix A-bar and the comfort grips.

Test ride only still at the bike shop.

The bike engineer says there's a defect and the Front fort and it has to be replaced making a loud noise. Waiting Your service department to reply to my bike mechanic. Not happy

Wonderfully capable EBike

II am 66 years old. have had my UD3 for about 4 months now. In that short timeframe I have logged over 2500 miles on it. Riding It is so much fun that hasn't been hard to do. It is in charge and it gets noticed. I ride it on roads, trails and in the woods. This bike cannot be stopped, I and have yet to see another bike that can outperform it at any price. It will climb just about anything, as long as you can stay in the saddle! It is a big powerful bike that might take a little getting used to at first due to the sheer size and weight of it. But it is precisely the size, weight and power of this bike that make it such so exceptional and comfortable. You will ride with complete confidence in your newfound "partner" and it will not let you down. Get the extra battery (you will not want to get off this bike) and the Magura brake upgrade and it is even better! It has opened up a whole new world, conquering terrain a lesser bike could not dream of tackling It is worth every cent I paid for it. It is superb. As for the people who work for Biktrix, they are second to none.
