Thanks, although I am hobbyist bike mechanic, I never heard of Coasting before. Frankly, doesn't sound very attractive - a complicated (proprietary) automatic gear system relying on functioning (proprietary) front hub dynamo... All that to address a practically non-existing problem: no one really has a problem learning how to use bicycle gears.

Agreed, the main reason for low cycling uptake in some countries is because it is utterly terrifying. I'm a seasoned cyclist in the UK; there are some roads I just will not cycle on because it is too dangerous to do so. If _I_ am too afraid to cycle on them, then what chance is there of people who have little experience of cycling picking it up?

Cycling uptake starts with cycling infrastructure, very few people have a problem learning how to ride a bike.

It's definitely easy to learn once explained, and every enthusiast knows - but as a cyclist living near a popular bike route, I see a lot of casual riders who appear to have no idea how to use their gears.

The most common thing I see are riders with the cranked up in a high gear on flat land, and you can see them almost standing or straining to turn the crank. I cringe to think about the pain they are inflicting on their knees.

IME once you spend a few minutes teaching someone about their gears, they're usually shocked at how much easier and more efficiently riding is, and enjoy cycling much more.

Part of the problem is selling front and rear derailleur gearing to cyclists for whom it does not make sense.

Internal gear hubs make a lot more sense for casual cyclists -- they are easier to learn, they can be shifted when the bicycle is not moving, and they are far less likely to drop a chain during shifting than derailleur gearing. They are also better protected from weather and impact.

Almost all of the utility bicycles I've seen in Japan and Europe had internal gear hubs. I didn't see many people commuting on the kind of bicycles that American cycling advocates seem to prefer.

And even if people do know how to use gears, the gears are often in need of some adjustment, so people just stick to the ratios that happen to work.

One of the main reasons I stuck my geared bike on the trainer and bought a single speed for London commuting - gears are FAFF to maintain. Yes, there's video tutorials, etc., but there's still a non-zero amount of witchcraft going on.

Worse is better on shifters. Old school downtube, non ratchetting shifters just work.

[OnlyOneCannolo]

Assuming you know how to work them, and are comfortable enough riding to reach down and fiddle with them.

[ldiracdelta]

And the entire market of 10-speeds figured it out before the new complex shifter systems became mainstream in th 90s. Fixees for the rest, I guess.

[OnlyOneCannolo]

Or automatic shifting for the untapped market of people who wouldn't figure it out but also wouldn't ride a fixie. I can see the concept getting more popular as the price of electric bicycles decreases.

Same. Used to live near Greenwich Park and the number of people struggling up the hills around there in high gear was amazing. Even in low gear, I reckon they're a bugger for average cyclists.

Wait, is this not what you are supposed to do? How do you go fast then?

[auxym]

Well, yes, but you need to accelerate first. Just like you don't accelerate a car from a stop light in fifth gear.

I hang out on some cycling subreddits and they commonly get questions from new cyclists that are totally clueless about how gears work. Some of them have it it completely backwards, ie start in a high (slow) gear and progressively shift down to a low (fast) gear as you get up to speed.

I always thought it was intuitive, but I guess I also got my first 5 speed bike around 7 years old or so, I can't really remember. I do remember having an RC car with 2 speeds Ang getting the principles pretty quick: gear one would accelerate faster but top out quick, while gear 2 had slower pick up but higher top speed.

Is doing this more damaging to knees than a standard weighted squat?

[dashundchen]

On it's own, I can't imagine so.

However I would think straining hundreds or thousands of time on a ride vs a few dozen squats for a set has a much bigger potential for injury.

I'd also add it's not uncommon to see riders with their bikes unadjusted for their size, e.g. they might be in an already weird position with their seatpost too low.
