New Juggernaut Ultra FS Pro 3

This is my 2nd Biktrix bike. My first was the Juggernaut Classic Duo. It was fantastic as well but I had decided I wanted full suspension as I mainly ride off road. We are lucky enough to have miles of off road trails to ride here. I typically try to ride 20 to 30 kms a day if I can. The new new Juggernaut Ultra FS Pro 3 has been nothing short of amazing. I have done a number of things to customize it specifically for me but it is awesome!

Brakes are the weak point. The 4 piston brakes should be standard on a bike this expensive. Also, the single battery really limits the range.

Too soon to review- initial notes

A lot to like! A few things to not like. Loved the whole buying experience! The customer support team helped me customize and get exactly what I wanted. Delivery was positive. Fedex came 2 days before schedule. Box and bike in great shape! The bike: just beautiful! Assembled nicely, since all I had to do was the handlebars, front wheel rack and pedals. And seat I guess. First ride. Motor was louder than expected. Kind of a clinky loud. Was surprised that if you try to downshift while pedaling, it stops the motor for a significant amount of time, causing you to lose critical momentum. But the power from the torque sensor, helps make up for any of that. Only a couple rides in. One at night to test the Armageddon light. Super nice so far. I’m sure I will keep testing it. That’s what I got it for.. trails!

Transformative. My face hurts.

My face hurts. From smiling too much.
What a blast it was to ride 16 miles and only using 15% battery suggesting I could get well over 50 miles with the 17AH battery - time will tell. When a hill approached, I kicked it up from Eco PAS 2 to 4 and breezed up the hill. A very steep dirt patch popped up and Sport mode PAS 3 made that lift easy. I did have some electrical issues, but they were resolved over the phone (a loose connector). So far, so good. This beast is strong. High quality. Glad I went with 3" tires - they breach any terrain and are just right for my needs. Now my two ebike buddies want to upgrade their hub bikes (Sondors and RAD) to Biktrix. Very happy with this bike.
