**Please note that information regarding the expected range on a single stock battery charge on one of our e-bikes is an estimate, not a guarantee. There are many factors that contribute to the actual, real-world range for an e-bike battery such as the age of the battery, temperature, level of assist, speed, payload, and terrain. Depending on these various conditions, it is possible to get less than the expected minimum range or greater than the expected maximum range.

+1-866-BIKTRIX

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.

Jaggernaut Ultra Duo 2 Step Over

I went on vacation and got home to my new BikTrix Jaggernaut Ultra Duo 2 Step-Over Camo Bike. Was easy to get together and get started. I charged up the battery and put 20 miles on it my first day. This bike is really fun! I am 40 years old but honestly feel like a kid again riding this bike. The customer service was great! They helped me find what would work for me and answered all my question promptly throughout the process. This Bike is awesome!!

Basically a well built bike, but there are issues...

After about 150 miles on my new UD3 I will say, overall, it is a solid, well-built bike. So far the 52V 17.5Ah internal battery averages about 20 miles total range on relatively flat, smooth terrain without much wind, tires at 25psi, at level 3 ECO mode assist mostly, no cargo and a 225 lb. rider. This is well below the hi-lo range Biktrix advertises. The Electric Blue color I ordered as depicted on the website was nothing like the purplish color that was delivered (see overlay photo); but they did issue a $450 refund so I can re-paint the bike to match. The sprung cruiser style seat squeaks loudly and may have been originally designed as a torture device; after the first couple rides, I had to replace it while my blisters healed. This despite my being use to bike seats. Also, there was a shipping delay clearing customs due to an "insufficient commodity description" that took Biktrix a week to rectify.

Thanks!

I don’t need that battery??? (Aphasia)

Great Bike - Quality and Power More Than Expected

Bike assembly was straight forward. Good customer support on a few newby questions. Exceeded expectations. Would definitely recommend
