Defective Freehub

I had a freehub failure after a few hundred kilometers of use. Unfortunately the bicycle was out of warranty and I had to purchase a replacement hub. The failure was that internal ratchet ring had lost it's bond with the hub and was slipping. Peddling barely moved the bicycle forward. Bitrix support was fabulous. Not only did they help diagnose and offer replacement parts but they overcame a big shipping problem delivering to a Greek island. My bike would be sitting DOA without their help and support.

Amazing bike and the Biktrix team are excellent at communication !

Embarrassing to say that during the minor basic assembly after recieving the bike. I popped the inner tube by not tucking it in properly before inflating :) So it took me a while to get a new tube. Finally rode my bike yesterday...Wow !!!

William Corwin

This is a bit off the subject. But I’ve made a request several days ago and haven’t got any response. My ultra FS is in the shop repierce that the axle might be broken the gears turn but the wheel doesn’t. Do you want to shop said perhaps it has something to do with the software? If you actually broken, it seems like it could be a warranty issue? Please advise feel

Good but

After about 6 rides in a 150 miles on the bike. Bike came with front flat tire and basically no air in the shocks. Easy fix but still. The Forks are not up to the specs of the rest of bike. I thought I was getting the 140 travel forks. So I will be getting a new fork. Sad after all the research I did for this bike. 😪 Also the seat has clips in the back for support one is laying in the trail somewhere. It would be nice if there was a bash guard or chain ring for the bike. I can't
find a after market one for the bike. The rest of the bike I love. Great battery and motor combo. I changed the bike when I ordered from 4 inch tires to 3 maybe thats why it same with 100ml forks. Read the find print twice before ordering.

Still a Fat tire wheelset, not a true MTB wheel as width is 60mm

Still, 26x4.00 are not for me or my riding style. These wheels, although still "fat", can accomodate 2.8 DH tires with good knobs for cornering, tracking, and more surgical handling. I have Maxxis DHR and DHF and they rock on these wheels. The 26 will be saved for a snowy day, the 27.5 are my go to wheels.

27.5x3 Wheelset

Bought 2nd wheelset because I was curious on how it would change my ride. 27.5 rear install went well, will be able to switch back to 26x4 no problem. Also trying 27.5 on front 26 on rear setup.

Good product, didn’t deliver on color

Product is good, wait was long and didn’t get color I ordered, also waiting on bell and water bottle holder still.

Tire review

Asked for the 27.5x3 tire that was on the Monte and ended up with a different tire brand.
