I’m a big believer in the future of self-driving cars. There is clearly a lot of risk turning a complex and unpredictable task over to a computer and all the attendant sensors, but we already accept a huge amount of risk letting easily-distracted and self-centered humans continue to do the damage they do.
So, I have to believe that we will all be safer when computers take over. The occupants of cars are much safer in a crash than they were when I was young, but the safety advances haven’t benefited pedestrians and cyclists. We are just as likely to get hurt when a car hits us as we were 50 years ago. I’m hopeful that autonomous vehicles could be a significant safety advance for those outside the car.
Thus, I look forward to the safety benefits that automated cars should bring. However, I worry about adoption of the new technology. Will a robot car be allowed to speed? Will it be allowed to make unnecessary lane changes to move one car ahead of the ‘dipshit’ ahead of it? What about yellow lights? Can you set it so that it will ignore them? How will the industry get aggressive, type-A drivers to adopt technology that forces their car to drive as if they cared about the safety of those around them more than beating the car next to them to the next traffic light?
The solution is to have at least two control settings; One (of course) would be the ‘law-abiding’ setting and the other would be the ‘Jackass’ setting. Using this setting would allow the computer to take every advantage, no matter how small, that the Type-A driver would take so that the owner felt he was beating the guy next to him. Over many weeks or months, the algorithm could adjust to a safer driving mode until the car was following all the laws and even common sense. This is somewhat analogous to the sales technique supposedly used by successful Chevette salespeople many years ago; the buyers knew the Chevette got good gas mileage – that’s why they were at the dealer. You sold it by accelerating hard and whipping around corners – this answered the buyers unspoken concerns about the performance of the small car.
Don’t sell the robot car based on safety and convenience – sell it based on the advantage it gives the buyer over the schmucks who can’t afford a computer car – this will lead to much quicker adoption.

The typical discussion on the question of e-bike access to non-motorized trails typically goes something like this:
Proponent: “Why are you against e-bikes? They are quiet and don’t damage the trails”
Anti: “Because they will hurt our access to trails”
Proponent: “They shouldn’t – they are just like regular mountain bikes but with some help for the rider – they don’t hurt the trails”
Anti: “They are motorized – don’t you get it? They will get faster and faster as technology improves”
Proponent: “But they don’t have a throttle”
This typically goes on and on and there is never a resolution just like most discussions on social media. Multiple government agencies have come out with rulings that e-bikes should not be allowed on trails that exclude motorized vehicles. The whole motor vs non-motor seems obvious to me but some agencies haven’t ruled on the issue and some do allow e-bikes on trails. Some specifically allow them for people with a disability. I assume that the rules on e-bikes will be clarified over the next 2-3 years as the industry ramps up their offerings. E-bikes won’t sell unless people have a place to ride them so there is a fair bit of money lining up to change the laws to allow e-bikes on more trails.
I’ve been involved in MTB advocacy in some form or another since 1993 and I do see e-bikes as a threat. The sky is not falling – YET – but manufacturers and some vocal e-bike users want to change the laws so that e-bikes are allowed on trails that don’t currently allow them. It’s very hard to believe that this effort won’t affect those of us who choose not to ride with motor power. In general, the proponents argue that because e-bikes don’t have a throttle and are battery powered that they should be treated as a different class from internal combustion motorcycles. Industry types and some agencies may buy this distinction but I think it will be lost on the general public who, sensibly, will see a bike with a motor and ask, “Why can’t I ride my motorcycle on those trails?”.
My imaginary conversation between a member of the public and an elected official or administrator goes like this:
Public: “I was out on the Crest yesterday and I noticed that there were several people on electric mountain bikes. That’s really cool that you allow motor bikes up there now – thanks!”
Administrator: “Well, actually those are e-bikes – they are pedal-assisted bicycles, not motorized bikes”.
Public: “I don’t understand – they have motors, right?”
Administrator: “Well, they have 500 Watt electric motors but they don’t have a throttle”
Public: “So how do they work if they don’t have a throttle?”
Administrator: “Well you have to pedal and the motor helps out – sort of like the old mopeds”
Public: “So how do you know that the motor is only 500 Watts?”
Administrator: “Well we don’t know unless we inspect them”
Public: “How often do you inspect them?”
Administrator: “Never – we don’t have the budget for that”
Public: “So, riders could modify the drive system to make it faster?”
Administrator: “In theory, yes, but we haven’t seen that happen.”
Public: “So I’ve got a CRF125 and it would be great to ride it on these trails with my daughter on her CRF50 – so it’s OK if I ride up on the Crest?”
Administrator: “No – sorry – it has a gas motor and a throttle so you can’t ride it on non-motorized trails”
Public: “Wait – you just said that bikes with electric motors are OK – I don’t get it”
Administrator: “Yes, but those don’t have a throttle”
Public: “That seems totally arbitrary – they have a motor but you allow them on non-motorized trails??!! I need to talk to someone at the Forest Service – this is ridiculous. If they can ride electric motorbikes up there I should be able to ride my dirt bike there, too.”
Like I say this is my imagination working – the conversation won’t go exactly like this but will likely be similar. Next step is that the people who ride dirt bikes get their lobbyists and industry groups involved and Honda, Kawasaki, Yamaha, Husqvarna, etc. see an opportunity to sell MX bikes and ATV’s in greater numbers. The government gets pressured and are left with a simple choice – allow e-bikes and other motorized vehicles or do a blanket ban on all motorized vehicles. A few people decide to use e-bikes on multi-use trails even where they are not allowed. Hikers and equestrians complain to the administrators. Since the administrators can’t easily tell the difference between (for example) a Specialized Turbo Levo Fattie and a non-motorized MTB, they are left with no choice but banning all MTB’s from those trails.
That’s one way you may lose access. Do you have other scenarios? Let me know.
Interesting to see this sign at a trailhead in Moab the other day. The BLM had to post both ‘No e-bikes’ and ‘No pedal assist’ since the bike industry has pushed ‘pedal assist’ as the preferred deceptive marketing term. I hadn’t made the connection until I saw this, but ‘pedal assist’ doesn’t sound like you have a motor – it just sounds like magic that helps you pedal.
With the lack of technical fluency of most of the population, I can’t blame the rider for not understanding that their pedal assist bike has a motor. Glad to see the BLM is holding the line on keeping motors off these trails. There are plenty of trails around Moab where motors are allowed – so I hope the BLM and other agencies continue to hold the line on this.
Interesting first visit to The Startup Building co-working space in Provo today to attend a Million Cups event. I met the building owner, Tom, and his family who seem to have made the space quite successful in the 4 years that they have owned it. Surprisingly, ‘Startup’ is the name of the family that started a chocolate company in the building 100+ years ago, and are still producing today.
I got a quick tour after the Million Cups event and was impressed by the number of entrepreneurs and students who have made this building in Provo their home.
One of the great things is the location. Right across the street from the Frontrunner train stop. Sure made getting to and from the event easy!
Along the Wasatch Range you almost always have a view:

I’ve ridden a number of dropper posts since about 2008. From the early days, I’ve sampled the Gravity Dropper, Crank Brothers Joplin, Fox DOSS and ended up buying the Kind Shock LEV in early 2014. For those of you who still haven’t bought a dropper post I’ll say that it’s one of the best upgrades you can make on your bike no matter what kind of bike you are riding – even a hardtail. If you like going fast downhill (or even if you don’t) it will give you more control and confidence. You’ll lower your center of gravity which gives more control in cornering and particularly on steep downhills the dropper will make you feel that you won’t go over the bars. If you’re riding flat to rolling non-technical terrain keep that fixed seatpost but if you are riding anything else and want to have more fun, get a dropper post!
One of my primary considerations whenever I buy bike parts is to get something reliable. Weight and other performance issues are important but always secondary to reliability. If I have to spend too much time fixing something it takes away from my ride time. If you have ever walked a few miles to get back to the trailhead due to a broken part, I guarantee that you won’t be thinking, ‘I’m so glad I saved 50 grams on that part – it failed but it sure is light!’. My experience with Crank Brothers several years ago was with a failed seatpost that wouldn’t return to the top. That pretty much ruined the rest of my ride trying to pedal uphill with a seat 5 inches below the correct climbing height. I knew a few MTB tour guides who were leading multi-day rides and carried a backup seatpost in their packs since they couldn’t fully trust the dropper posts they were running. That wasn’t for me.
So, in 2014 when I was shopping, the consensus was that the Rock Shox Reverb and the KS LEV were the most reliable posts. I tried them both in a shop and settled on the KS. It seemed particularly solid and the shop owner said he had fewer returns for repairs than with the RS post. The Fox DOSS was also out at that time but didn’t have as much of a track record so I wrote that one off.
Installation and Setup:
My bike (Yeti ASR 5C) didn’t allow for internal cable routing but the setup wasn’t really an issue. The external cable routing was clean and has never been a problem. Some early generation dropper posts had cables attached to the moving portion of the post (usually right at the seat mounting) which meant that the cable moved on the bike as you went up and down with the post. This was particularly annoying on the Crank Brothers Joplin as the cable housing would sometimes hit my leg or hang up on the frame somewhere. The LEV had a clean attachment to the top of the fixed portion of the post. The only weak point the shop warned me was the cover over the cable attachment that often fell off during use. The solution was to put a tie-wrap around the cover. Easy solution – but sort of disappointing to get a brand-new post and have to throw a band-aid on it right from the start. But hey – it works.
The post has an air cartridge to move the post. The Schrader valve is on the top of the post and requires you to remove the saddle to adjust the pressure. Sort of a hassle, but I’ve only set the pressure once and haven’t lost any air so I haven’t had to add air all this time.
The seatpost head uses the preferred 2-bolt attachment so adjusting the seat angle is easy and very secure. I’m not a big fan of button head screws as are used on the LEV since the hex size is usually a size smaller than a socket head cap screw. With the socket head cap screw you are less likely to strip out the hex if you are a ham-fisted mechanic. I understand the use of a button head since it is less likely to injure the rider in a crash than a socket head cap screw. So I’m just careful to fully engage the hex key and watch my torque.
Out of the box there was a bit of side-to-side play (rotation) of the post but it was quite small and not noticeable when riding the bike. It’s more pronounced now than when I got the post but it is still just barely noticeable when riding and doesn’t bother me. I know some people who care a lot about these details so if you are one of those people you might not like it.
On the trail:
One of the key issues with any post is the remote lever design. The ergonomics and feel of the lever are critical. You want the lever to be located in a good position so that access is good – the most critical time to drop the post is just before a technical section and that is the last time you want your hand off the bar trying to activate a lever. The lever shouldn’t require too much force or throw (travel). It should also have enough ‘feel’ so you can detect the release point and know when the post will move. The KS lever meets all the critical criteria. I initially thought it might be a bit small but I’ve come to like it. If you’re running ODI lock-on grips the lever even integrates with the grip. Take off the inside collar and the clamp of the KS lever just slides onto the grip. Nice detail.
Some dropper posts have an adjustment for the speed that the post goes to the up position. The return speed on the LEV is governed only by the initial air pressure setting and the speed has always seemed fine to me. Just fast enough and very consistent.
This post has been pretty much bullet proof. I rode it for 2 1/2 years before the first issue popped up. There was a noticeable clunking and a bit of stickiness when moving up to the top position. I assumed that I would have to send it back for service but I opted for the very simple sealhead service as described here http://blog.artscyclery.com/mountain/ask-a-mechanic-service-and-maintain-your-kind-shock-lev-dropper-post/ This was surprisingly easy and put the post back to like-new condition after just 30 minutes of effort.
The LEV is a good post. Reliable and consistent performance and it hasn’t let me down. I’m starting to shop for a new bike and I definitely want a KS post on my next bike.

One of the reasons that golf is so popular in business is that people of different abilities can play together. It’s also a good game for socializing because there is a lot of time to chat during the game. I’m not a golfer so what I’m going to write here may be way off, but the whole idea of the handicap is that you can have people of differing abilities play the same round and then compare scores afterwards. So, for business it’s the great equalizer. Could you imagine people going swimming together? ‘Hey Bill – what do you say we race each other over 400 meters and then talk about the Westco project?’. It’s not going to happen. Or – ‘Steve & Jane – want to play some 2 on 2 hoops?’. Well if the last time Steve and Jane picked up a basketball was at age 13 when they played a game of HORSE, there is no way that 2 on 2 game is going to be any fun for either side if they are playing some ex-college basketball players.
For the brief time that I was in Sales I quickly realized what a disadvantage it was not to be a golfer. If money is the engine of capitalism, golf is clearly the lubricant. A few years ago, the phrase, ‘Cycling is the new golf’ became popular around some corners of Silicon Valley – well not my corner of the stagnant semiconductor capital equipment industry – but certainly among the social media/killer app/Sand Hill crowd. I still never got this because the difference in endurance between someone who rides a bike once a month and someone who rides 2-3 times a week can be quite stark. I just can’t see the casual cyclist (dare I say Fred?) hitting the Portola Loop and climbing Old La Honda with a Cat 3 leg shaver. Fred’s going to get dropped on the first Strava climbing segment that is over 1/10 of a mile.
But the other day it dawned on me – the e-bike is the great equalizer – to use a golfing term – the handicap – that allows people of varying ability to participate in the same event. Now all we need is a good way to express that handicap. Is it the number of watts your e-bike puts out? Maybe you add your bike wattage to your actual wattage? Or take this number and divide by your weight so you could have a power to weight handicap?

Still the e-bike analogy seems pretty weak. Even a noob golfer must swing the club (actually a bunch more times than a good golfer), still must walk the whole course (or ride in the same cart) but the e-bike rider can’t feel the same satisfaction as the ‘traditional’ rider, can he? If you keep up with the group on your e-bike it’s not because you earned it, right? You just paid to keep up just like you had called Uber for a lift. Just like anyone, I hate getting dropped but it builds toughness – I don’t know if there is anything more humbling that I experience on a regular basis than getting back to the coffee shop 10 minutes after my buddies.
As humbling as getting dropped can be, it makes me want to work harder and it reminds me that there is ALWAYS someone better out there. Plus, isn’t toughness one of the attributes we want to get out of our athletic pursuits? If that novice golfer had a battery-powered exoskeleton that allowed her to swing more consistently and strike the ball harder would that be allowed on the golf course? Why do we think a motorized bike is OK but not a motor-assist for the folks lifting at the gym?
I don’t have a problem with folks using e-bikes out on the road. If it gets them out there that’s fine. If it allows them to commute, ditch the car and reduce pollution that’s even better. But if you’re in a competitive group ride (whether it’s a loop with your buddies or on a Century) be honest that you are on an e-bike – don’t try to disguise it. If you’re happy that’s great – just be willing to talk about your handicap just like the golfers.
Now that I’ve said all that – don’t even get me started on mountain bikes with electric motors. I don’t care what you call them or what rationalizations you come up with – they are motorized bikes and please keep them off trails that are designated for human power only.
