I don't motorcycle anymore but did for a long time and did both a huge amount of riding and some very serious maintenance jobs. I have kept bicycling thousands of miles a year since. In the past I did a bunch of different types of bicycle racing. Never did motorcycle racing but I did go to quite a few track days.

In general with a few exceptions everything on motorcycles is far more competently engineered.

Bicycle manufacturers brag about engineering a lot but actually seem to employ very few engineers. The bicycle industry is still re-engineering things like brakes over and over when all those lessons were learned on motorcycles decades ago and the bike companies could have copied almost all of it from motorcycles.

There's just a lot of stuff on bicycles where the tools are more expensive than the motorcycle equivalents and the maintenance procedures are more annoying. Motorcycle brakes are a great example. Things are relatively standard and all the tools are affordable and the maintenance procedures are great. Do the same job on hydraulic disc brakes on a bicycle and it's all terrible. Tools cost 3x more and might be vendor specific, procedures are terrible because of the design of the brakes, and the job probably takes longer.

You can go spend more on a Trek or a Specialized than a lot of motorcycles at this point. Other than the amount of carbon fiber there is almost no justification for the price, especially since 99% of the bicycle is outsourced.

I always found the education level among motorcyclists in terms of how a bike actually rides much higher. The % of "expert cyclists" who understand basics like counter steering is shockingly low, and bicyclists are far more likely to have poor understanding of how to ride in traffic safely. Mostly because motorcycling actually has a training & education system. I always felt like motorcycling actually taught me more about bicycling than the reverse.

Absolutely agree with the high end bike vs. motorcycle cost analysis. My new, but prior floor year Ducati was roughly the same price as either of S-works mountain bikes. Sorta crazy to the uninitiated. Or anyone.

I have a pet theory, that the proliferation of top-shelf Class 1/pedal assist Ebikes ($14-15k) has given manufacturers the green light to raise prices on top of all the covid supply chain gremlins. The number of $10k analogue mountain bikes has blown up in the past 3 years.

I do wonder how any cost impact that comes from miniaturization of bicycle components (coupled with smaller production quantities using composites) looks compared to their moto counterparts. Offering the same bike frame with 5+ different component builds must have some cost ramifications with supply chain management in buying /allocating groupsets & components en masse. It does seem like the mountain bike market has matured a bit: fewer radical yearly geometry changes, more streamlining and sensible, incremental changes. Just my thoughts as a voracious consumer of bike stuff. I'm all for a standardizing brake bleed ports and hydraulic maintenance - mineral oil please!

It's funny, I've anecdotally noticed the opposite here in Austin. The number of motorcycle riders who clearly have no concept of handling a moto seems to outnumber the people acting the same way on bicycles. Can't speak to your locale, but Austin certainly has a strong cycling community with lots of proficient riders; I think I'm also in a bit of a filter bubble with my riding crew.

I'm curious if they really could just copy something from the motorcycle world? In particular, I would imagine that the constraints on weight and power that can be applied by the user are very very different.
Yeah, I think a number of these comments are significantly disregarding the engineering challenges faced in bicycle manufacturing. I suspect trying to design a < 7kg bike that can withstand the forces of a 90kg rider putting out 1500+ watts would make many moto engineers pull their hair out.

There’s a reason many innovations in the bike world have come from aerospace.
