The Short, Turbulent Life of URT Suspension
That last photo of the single speed made me think that this could turn into a modern design for gearbox full suspension bikes. Eliminate chain growth, no tensioner, low center of mass, high pivot. Any thoughts? Would locating the mass of the gearbox on the rear triangle eliminate all advantages of reducing the unsprung mass in the swing arm? Or since the mass is close to the pivot point would it not make much difference? Any way to reduce the negative effects of URT design that were mentioned in the article?

Don't Punch the Baby - Opinion
@therage43: wow you’re pretty paranoid. All these people sneaking around with hidden electronics. Most people in my state can’t afford even a $3,000 bike, let alone a stealth mountain ebike. There are going to be a bunch of sneaky dentists and Doctors taking over our trails any minute. Don’t you look on the bright side? My girlfriend has a debilitating chronic illness. There are months out of each year when she could only ride 10-20 minutes with me in the mountains if she tried. I have thought about getting her an Ebike so she can take it easy and maybe keep up for an hour to get some enjoyment. I wish I could afford one at all, let alone a fancy one that would be so “sneaky”. Most people don’t run red lights just to be sneaky, or steal candy from a baby. If you’re worried about people sneaking around stealing your rights to public land maybe you should start looking at the politicians that we elect, or the private companies that exploit the natural resources of our public lands. Are you going to let them do that? What about just getting people into the sport who would never know the enjoyment until getting a ride on an ebike? Rent an ebike once a week and then graduate to a regular Mountain Bike. What about people with disabilities? Out of shape family or friends getting the chance to keep up with their athletic friend. Might be good motivation.

The Mountain Bike Technology Wishlist - Opinion
@bogey: That is the most brilliant thing I've heard in awhile. Seriously. Very difficult but could be worth it.

Martyn Ashton Rides Whistler - Video
Such a special family you all have created. And such a special bike. I wonder how difficult it would be to add some sort of forward/backward weight control mechanism onto the seat. If somehow he could get his weight off the back it seems like he could have much better control of the bike. I don't know if it would be a sliding mechanism where he shifts his own weight completely, or if it would be motor assist and locked out on demand. They are getting into the robotics of prosthetics already with that custom bike, one step further could make 1,000% difference in performance and stability. Let me know if you want more info on what the design might be like. I am imagining a system similar to fully mechanized legs, where the system senses your weight shifting forward and starts swinging the leg in a natural movement. It might sense him trying to shift weight, or simply a forward/backward leaning sensor. Then the whole seat (and legs?) would slide on a rail with servo motors. The trick would be to get the "dead-band" or sensitivity correct so that it holds in a stable position during rocky riding without sliding back and forth when he doesn't want it to (time delay on the sensor output might be helpful). Any robotics engineers out there? Now I'm even thinking of a more passive system like a suspension seat that allows the bike to move under his weight. Imagine him floating on a cloud while the bike bucks around underneath. An ambitious design either way. Maybe a combination of passive and active?

From the Top: Pinion's Christoph Lerman
@jzPV: I have a Pinion P.12 and I don’t notice any efficiency loss. The C line might be even better. There are other articles that note the loss is the same as a dirty chain on a skewed chain line. I honestly don’t understand why people are so excited about 1x drivetrains, the chain is almost never in the most efficient position. You have the most loss when you are in the lowest gear which is when you need to conserve energy the most. I find myself being able to find the perfect gear more often on the Pinion. Instead of grinding gears with a derailleur it feels like I am more precise and able to use my energy more effectively. Efficiency is probably more in the rider technique than the the actual machine.

Is This Linkage Fork the Future of Suspension? - Crankworx Whistler 2017
I think it looks like a bike I want to try riding, not sure why people think it looks bad. Dumb and Pretty vs. Intelligent and Ugly. Who cares how it looks, everyone will get used to it after 10 years and think it's normal. I understand people not wanting things more complicated, but it might be worth it. Just wondering the weight comparison. Seems like this could become a thing for downhill racing, until they invent a nice soft cloud to float down the mountain on or some kind of hover-bike. Hover-Board …
