I recently purchased a Biktrix Juggernaut Ultra FS Pro 3 17" medium frame, brushed aluminum finish with 3" x 27.5" tires, offroad use, no speed limit, during their Easter sale for $3299 Canadian. I added the range extender battery for $649 because I know I'll likely use the highest assist level most of the time, and I don't want to worry about my range.
I live in the Southern interior of British Columbia, Canada where we have lots of hills, so the 160Nm of torque will be useful.
I apologize in advance for my long winded post, this is an introduction as well as a review of my purchase.
Overall, I'm happy with my purchase; however, there were some hiccups, and the available assembly videos from Biktrix were generic and somewhat vague.
Installing the range extender battery bracket was a hassle, I had to file the mounting slots, use misc. washers instead of the included spacers, and rotate the rear shock so the lockout lever didn't contact the battery when the suspension compressed.
The plastic bracket doesn't seem very sturdy, if I plan on hitting any jumps, I'll either remove the extra battery, or add a bungee cord or something, just in case.
Initially, the headset had a bit of play at the lower bearing after tightening the top cap bolt.
I contacted Biktrix, suggesting that I might need a 5mm spacer.
They gave me a $50 credit to take the bike to a local shop for adjustment.
Before I went to a shop, I disassembled the headset, and noticed the star nut was right at the top of the head tube.
After some online searching, I used a brass punch to seat the star nut 1/2' into the head tube, then everything tightened up properly.
There was no indication that the integrated headlight wire with the white stripe was positive, thankfully there's Google.
There was no mention of properly bedding in the brakes, which I learnt after 13km of riding and glazing them.
Googled how to resurface and properly bed them in afterwards.
The 180mm rotors and 2 piston calipers were sufficient for the rear, but the front brake was weak, so I ordered 203mm rotors.
Biktrix sent me the required QM42 post mount spacers, but they didn't include the required 20mm and 25mm hex head bolts for installation.
I've only installed the rotor on the front, I don't want my rear tire locking up too easily, I may install the 203mm rotor on the rear in the future.
Ideally, the assembly instructions should have mentioned using blue Loktite on certain fasteners, ie: front axle through bolt and pedals.
After 200km, my left pedal came loose, and by the time I stopped, the aluminum crank arm threads were destroyed.
Potentially loosened from pedal strikes with the 170mm crank arms.
I've adjusted my high speed cornering stance to avoid pedal strikes, but sometimes, if I'm turning and going uphill, I need to pedal to keep moving, maybe I'll just use the throttle in these situations until I can find some compatible 160mm crank arms, all I can find are 150mm so far.
Biktrix sent me 2 crank arms, 2 pedals and the crank arm removal tool, I only paid shipping.
I set up my suspension sag, fork compression and rebound and rear shock rebound for on road riding for now.
After measuring my true wheel circumference, I changed the Bafang DPC-18 wheel diameter from 26" to 29".
The speedometer is quite accurate compared to my GPS.
On a side note, the bike is quoted as having Biktrix 100mm travel inverted forks, my forks measure 140mm travel, bonus.
In the future, I'll likely upgrade the rear axle to a star ratchet style.
I look forward to learning more from this community, and sharing what I learn.
