Biktrix Juggernaut Ultra FS Pro 3 - 350 mile update

I now have over 350 miles on this bike, most of that off-road.  This bike has been great for my riding style.  I have the optional range extender battery which allows me to ride about 75 miles off-road on a charge.  My riding includes many long hills and loamy conditions that burn through power too.   

I have had some creaking noises which sound like they are coming from the handlebar area and possible the motor area.  I checked and rechecked everything and all is tight.  

When I bought this bike they offered several upgrades.  One of which was a $300 Wren hub upgrade.  I passed on it thinking why would I need that?  Well, I found out why.  I was up at Little Red Rock on a loamy hill.  I hit the throttle and heard a snap and then the cassette just spun, no longer driving the wheel.

Luckily I was up hill so I was able to coast down to a main road and get picked up.  I got home and took the hub apart and sure enough the ratchet teeth had sheared the ends off.  

Now I decided to get the upgraded hub.  

If you have an electric mountain bike with a high torque motor like this Bafang Ultra M620, best to also get a hub that can support it.  

This bike is heavy but I used to ride dirt bikes back in the day so I don't mind the weight.  The bike alone (no batteries) is 72lbs according to Biktrix.  The main battery weighs 10.3lbs and the range extender weighs 7.6lbs.  Total weight is about 90lbs.  

Here is a video that shows the use of the throttle for some steeper or loamier bits in the beginning of the video.  Watch for my left thumb applying motor power (throttle).  Starting around the 5 minute mark, I begin the downhill portion that shows the suspension soaking up the terrain at around 20mph.

This next video shows a steep but short hill when I use the throttle to climb at about 25s in.
