If it's a Chinese e-bike, it's probably lying about being IPX67.

OTOH, Riese & Müller $15k USD e-bikes aren't IPX anything because the Bosch components aren't. If you get it wet, just kiss that money goodbye. Absolutely bonkers.




Huh, that’s not my experience. My wife rides to work on her R&M e-bike, every working day, all year round, in sun, rain or snow. Daily distance is about 40km (25 miles), two hours back and forth. Not a single major problem caused by water in more than 5 years.


They don't mention any specific IPX rating, however they claim it's "rain resistant".

https://www.r-m.de/en-us/service/faq/

Yes. You can use the system in the rain without any concerns. It is protected against rain and splashes, but not against riding through rivers when the motor is submerged in water.

Equivalent of about IPX54. To me, this means it's not really waterproof (IPX?7) should it fall a puddle when it rains. Never spray it with a garden hose or pressure washer while washing. And, it's really a gamble to take it in the rain. Plus, like cell phones, they tend to lose IPX protection when repaired because of customary sloppy repair jobs that fail to restore gaskets.


I think it really pays to go with an e-bike from an actual bicycle company. The Trek TQ system for example is submersible (IP67) and has a 2-year warranty, same as Bosch.


Is IP67 safe to wash like a car? Soapy sponge and reasonable hose pressure (not pressure washer) spray?


IP67 means "completely dust proof and submersible up to 1 meter". You can safely hose it down to clean it, pressure washers are probably a bit much.


There's actually bespoke pressure washer codes for the IP system, suffixing with a K

https://www.polycase.com/techtalk/waterproof-electronic-encl...

That said even ip66 is supposed to be resistant to 'jets' of water, like ~hose pressure.

Also, fwiw, I've never seen these used on prebuilt ebike components.


Is it safe to generalize like that? IP67 is a certification criteria that says that it must withstand conditions for certain amount of time during the test. But it doesn't say anything about doing it twice or how long you must wait between tries. For electronics it sometimes achieved by gel that can hold liquid for 30 min before water penetrates. It may eventually get dry again, but that is not covered by certification. Another point is that testing is done in distilled water, any impurities like oils can increase its penetrating ability and reduce the time. To me it looks like it's all down to actual manufacturer and item. IP rating is better than "splashproof" but still very vague.


$15K ???

I’m just checking their website. If you buy a “Culture Touring” e-bike from Riese & Müller you pay about €4K.

That is still a lot of money. But not nearly as much as $15K.

That's your costs where you are. That's not what they cost where I am. https://electricavenuebike.com/store/riese-muller-load-75-ro...


Yes. I was trying to make a point an out absurt price differentiation based on ___location.


Buy lots there and arbitrage them here. ;) (Might not work because of the warranty arrangements.)

Also, it appears a subset of Americans have way, way too much money and are begging to be relieved of this burden.


I’m glad you wrote this. I have one of these, and I love it, but haven’t ridden it in the rain. Now I won’t. I thought it might be okay because, as you pointed out, it definitely wasn’t cheap.


Here in Switzerland they rent them out (carvelo2go) and they seem to be doing just fine in (rainy) Switzerland.


Serious question, why would a person spend that kind of money on an ebike? An entry-level motorcycle is less than half that. What benefit does the bike get you that a motorcycle doesn't?

One example among many:

https://powersports.honda.com/motorcycle/cruiser/rebel-500


Convenience and sense of freedom. No license required, can lend it to friends or kids. Can be parked anywhere. Can be loaded on a car, ferry and some places even the metro. Can ride them on bike lanes, the forest and the sidewalk. More approachable diy maintenance. Don't need full leather protection, just a helmet and t-shirt and you are good to go. If you are only traveling max 30km within the town, you don't need anything faster.

Bigger isn't always better.


> Can be parked anywhere

Jesus I wouldn't park a $15k bike anywhere...


This is hard to believe but if true it's insane. The claim is, 2 million bikes are stolen in the USA every year.

https://cyclingindustry.news/bicycle-theft-surpasses-2-milli...


Some bicyclists in Palo Alto do, probably because they can't take their Ferrari's with them. A former business partner had a ~$8k bicycle stolen from Castro St. downtown in a very public area. All it takes to steal is 30 seconds and a battery-powered angle grinder. If someone doesn't have Tile, AirTag, and a GPS tracker on such a bike, then they're an idiot.


You took the Most expensive example to make your Point.

Who even owns a 15k bike? 0.0001 % of the population?


Did you actually read this thread? We're specifically talking about a $15k ebike.


Anywhere, including indoors :)


If you're afraid of it getting stolen you can buy insurance.


"Hi, I'd like to insure my $15k ebike. How many times has it been stolen you ask? Oh only a few. Half a dozen at most. Hello? Is anyone there?"


Hahaha. I hope a precondition to any bicycle theft includes requires 1 or more tracking devices and not transiting anywhere near a major metropolitan area or any city area with a drug problem.


Serious answer: they are lighter, quieter, go slower, handle differently, and have access to different infrastructure.

The lighter and slower bit may sound glib, but it makes a huge difference to what it feels like to ride them and to have them ridden around you.


a Riese and Muller is not a light bike


It's a heavy bike, but a very light motorcycle, which is the point


I'm curious too when bikes became that expensive. I just recently started looking for a new bike. Every major bike brand (Specialized, Trek, Cannondale, Orbea, Canyon, Santa Cruz, etc...) all sell bikes between $4000 an $18000! That's regardless of whether they are e-bikes or non-e-bikes.

When did bikes get that expensive? I bought a "brand name bike" just like 6 years ago for $900 and thought I was going way out of a normal budget.


Even 20 years ago, $900 was on the lower side for a serious bike but the big thing to remember is that e-bikes are transformative: they make daily commuting practical for many people who are not avid cyclists and especially so for parents.

That means you should compare them to cars: I bought a cargo e-bike for just under $3k when I needed to take my son and all of his stuff to daycare near my office ~6 miles away. I certainly used to bike that distance before but the weather, workday timing, etc. meant I never did it more than 3 days a week before, but the speed & cargo capacity of the e-bike made it my preferred option every day.

The other people who didn’t live within walking distance all drove, so their trips took longer door to door (congestion around the school alone was 20 minutes) and my expensive e-bike was the equivalent of a couple months of what they spent on SUV payments, parking, gas, and insurance. Plus my son _loved_ going on the bike every day (it helped that we went by the train yard) while most of his classmates protested going in the car because they’re so isolated with nothing to see.


E-bikes imported to the US from Europe for sale to Americans who have essentially unlimited funds and little concern for what things actually cost.

For mechanical bikes, they've always been (relatively) expensive. Here's one for $16k: https://www.cannondale.com/en-us/bikes/road/race/supersix-ev...


Yes they all very sell expensive bikes. They also sell less expensive bikes.

At a quick glance for road bikes: * Canyon starts at $1899 * Specialized starts at $1200 * Trek starts at $999

If you want a more upright hybrid, they can be found at lower prices.

> I bought a "brand name bike" just like 6 years ago for $900 and thought I was going way out of a normal budget.

I'm curious what you got for $900. I doubt the current iteration of that $900 bike is now being sold for many thousands.


> What benefit does the bike get you that a motorcycle doesn't?

Exercise and silence.


Most bikes are not silent. Worse, it's getting popular to make them loud. I was looking for an e-mtb recently. Tried a Trek ($4.5k down from $7.5k), ridiculously loud hub. Sales person claimed (falsely) that the more pro the hub the louder.

Talked to another dealer who gave me the same story.


MTB hubs are noisy as hell anyway, and yes, the more expensive the MTB the noisier the hub. For pedal bikes it's about being able to pedal without doing a full rotation and not losing power or wasting energy


> Sales person claimed (falsely) that the more pro the hub the louder.

What's false about it? Pros tend to ride wheels with loud hubs. It's kind of a known thing.


Even loud hubs are more silent than most motorbikes.


It's kind of true. If you want the hub to engage right away when you pedal, you'll need the rachet mechanism to have more points of potential contact and those points will all make clicking sounds when you're coasting.


What about EV motorcycles? That at least solves noise.


You can attach trailer to bicycle and use it to transport your kids to nursery/school during winter. There I live both things would be illegal with motorcycle.


Sounds very dangerous to me


Why would attaching a trailer to your bike be very dangerous?


Total bike and trailer builder and believer of yore here.

One can fail to appreciate the additional breaking forces and shifts in balance a loaded trailer introduces to the bicycle.

Where the trailer attaches should be as close to the center of gravity of the bike & rider as possible so the trailer's resultant forces have the least leverage.

The trailer hitch should be rotationaly neutral which is a gentler way of saying if the trailer flips over it should not take the bike down with it.

If the trailer has its own breaks they should slightly and lightly lead the bikes rear break.

Being careful helps, I never wrecked, but do see how the addition of electrical assist does up the concern as it could result in more mass moving fast.


I've been rear-ended by other drivers a couple of times, once in the centre of town. If a child in a trailer been between the two vehicles they would have been killed. The reason for one of the rear-endings was that the brake rubber came of the pedal. I don't trust other drivers to not be on their phone or to properly maintain attention at all times. The OP also said that he did this in winter time. Here in the UK there can be black ice on the road at that time of the year.


or a escooter or one of those things you just stand on and it moves? The main reason to ride a bike nowadays is for pleasure or exercise and a ebike defeats both.


An ebike can be for both pleasure and exercise. Most ebikes are pedelecs - you're still cycling, you're just getting a boost. They aren't loud, you just either get somewhere faster or with less effort. I find an ebike to be more pleasurable than a regular bike 90% of the time.

Just because you're doing less work, doesn't mean you're doing no work. An ebike can provide mobility for people who aren't in perfect shape. Ebikes can also allow you to use your bike for more errands, like getting groceries that people would otherwise not do on a regular bike.


That's fair. I can see how an ebike might encourage people to ride them more compared to owning a regular bike and never using it!


With an ebike you can ride in bike lanes, sidewalks and many other places motorcycles are not allowed. They can also park loads of places motorcycles aren't allowed plus you get exercise.


Yep. Ebikes can do a lot of things motorcycles aren't allowed to do. For example, it's customary (while illegal) for ebikes to not stop at stop signs in the US because there's little-to-no enforcement of it compared to the enforcement of traffic laws against motorcyclists.


¯\_(ツ)_/¯

It's a stupid amount of money for what it is.

KTM makes an 18 kW e-motorcycle for $12k USD.
