 Just picture this somebody is riding along on their electric dj bike wearing those 3D printed glasses while their kid is riding on the shotgun seat that got a dropper post upgrade from pnw meanwhile they have the hang time app running on their phone telling them how much air they got before they cased that last speed bump.

 A e-dirt jump bike has to be the most ridiculous thing I’ve seen lately besides new bike prices.
  • 15 1
 About as useful as an e-pogo stick or e-unicycle

 Exactly. Kill it before it reproduces and shoot pull the designer's fingernails out one by one.

 I can’t wait till there’s e-BMX bikes....for fat people with DUIs.

 @bman33: Leave the Fingies alone but definetly put that piece of $#!t in a museum as how not to make a DJ...
I mean come on, who thought that was a good idea? I would rather have an electric BMX for , uh... 'commuting'

"The perfect bike for jumping the sharkfin"? STFU.

 Either buy ugly 3D printed glasses for 400 bucks like a chump, or buy a Prusa Mini and make your own signature REALLY ugly 3D printed CUSTOM glasses for $361! (350 for printer, 11 for the lenses out of soms gas station shades)

 Kudos to Shimano for jumping on the new six bolt standard so fast.

 Is it just me or does it seem PB is doing everything possible to convince consumers that the new sram rotors are a significant leap in tech. Seems that every pit walk or dh bike photo has the rotors name dropped specifically like its a ground breaking innovation?
  • 12 0
 Just because you can put a motor on a DJ doesn't mean you should.
  • 6 1
 Man those Sram rotors are ugly! Also wow Sram you are so innovative with your 2.0 mm that has been used by Magura for years now, also TRP is using 2.3 mm, the future is now old man.

 Shoulda gone with 1.99.

 @SJP: That's would be such a Sram thing to do!

 There’s a few pieces of bike tech that have changed the game; Narrow wide chainrings, dropper posts etc. Get ready to add that Pabst/hand-up shirt to the list!!!

 how many years did it take sram to realize that previous centerline rotors were shit?

 So Thor are bringing out clothing for "E-Bike Rides" ......................... ok, things just got strange

 @boozed: I love that the first thing mentioned about said shoes, is their "superior walkability"...

 I see the fatbike has a 73.5° seat angle, am I the only one who does not like this seating position ? You feel folded in two at the hips. Maybe it's ok for road use head in the bars, but I don't like it for trail/AM use, so why keep it ?
I have a Honzo ESD at 77.5°, going to almost 79.5° at sag, and I wish there was a fat with the same geo (65° head angle), is my anatomy kind of weird ?

 How good are TRP brakes compared to shimano? Those seem like a good price.
  • 2 0
 I was considering the older Slates before I got my SLX brakes, they seemed pretty unremarkable; reviews mentioned they're not as powerful as Shimano and struggle with longer descents. New ones should be better for that in theory, if you don't need DH level performance they're probably fine. The price is rather nice

 Have Slate T4, they are boring, always work, linear, utterly without interesting character features. They need bleeding around same distances as pad changes and after river crossings they simetimes creak for a minute or so. Ah yes and they seem to be absolutely indifferent to what oil you use...

 So who do I have to have compromising pics of to get the new SRAM rotors.

 I need to arrive.
