    concerns with ebikes laws and ways to improve them

    The fact that non-compliant ebikes are sold isn't really an argument of anything other than "people ignore rules when they feel they can get away with it" (whatever your preferred definition of ebike is). Don't delude yourself into thinking that the government couldn't do something about that...

    Do I need an eMTB?

    FWIW, a good non-electric MTB that will hold up to trail use starts pretty close to 1k these days, and thats likely a hardtail (suspension fork but rigid rear). You can get into a low end full suspension in the low 1k range. Adding ebike stuff obviously adds cost. A lot really depends on what...

    California DMV getting tough on e-motos?

    I've been told the e-motos like the Sur Ron and Talaria have become a real issue on the local MTB trails. Mostly younger riders brapping it up. There have been some police interactions with mixed responses (the usual young white dude "you can't tell me what to do!" along with some people...

    Wireless Earbuds for cycling

    I occasionally wear just the right earbud from my my airpod pros while riding solo. Keeping the left ear open lets me hear cars and such. I would never recommend headphones that cover both ears, no matter how open they are. Even with just the one earbud, I only do that on routes I'm very...

    Brose releases 48V system motor and a concept motor with an integrated stepless gear system

    I suspect gates belts will be fine with the torque from a motor. Their main issue I've seen is they handle foreign object damage really poorly; I had several singlespeed MTB friends switch to gates setups back in the mid-late 2000s and within a year they had all switched back to chains...

    Canada to restrict class 3 ebikes to 20mph

    Urban fixie races/alleycats are basically for people who want to deliberately ride like idiots. The whole thing grew out of bike messenger culture, where time is money and they would take every shortcut possible to complete deliveries as quickly as they could. The mythos is they liked track...

    CLASS 1 EBIKES: A VANISHING BREED?

    In the distant past I've gotten my carbon road bike up into the mid 50s a handful of times descending mountain roads (backside of 33 over the border from harrisonburg in VA and 211 dropping into Luray off skyline drive). I just remembering getting hyper aware of the fact that I'm riding a sub...

    Canada to restrict class 3 ebikes to 20mph

    I'm genuinely curious how you arrive at the conclusion that a 20mph cutoff makes an ebike inadequate as a transportation solution. Because I have several friends who are mostly or entirely car free, and of the ones that even have ebikes (probably less than half) they have utilitarian class 1/2...

    Canada to restrict class 3 ebikes to 20mph

    Uh, what? I'm not arguing for a specific assist limit, just noting that energy does increase much faster than speed does in response to someone who was asking about studies for "safe" speeds. That is something that has been studied in the automotive realm. If you're talking potential to...

    Canada to restrict class 3 ebikes to 20mph

    I think the various speed cutoffs/power definitions/etc for ebikes are not really about ebikes in traffic with cars, they are setting limits for ebikes sharing space with non-powered user groups (pedestrians, cyclists and similar). Unlimited power 2 wheeled vehicles for purely road use...

    Canada to restrict class 3 ebikes to 20mph

    Something that hasn't been studied for bikes specifically but certainly has for cars is that kinetic energy increases with the square of velocity (the formula is K=1/2(mass*v^2). Going from 20mph to 30mph with the same mass more than doubles kinetic energy (for 100kg of moving mass, 20mph is...

    What's your opinion on the "Idaho Stop" law?

    I'd say the idaho stop codifies how most cyclists learn to ride anyway. I've always tried to be a law-abiding cyclist but there are definitely situations where its best to run a red light (either because it simply won't detect a bike or the way cycles line up work for cars but not necessarily...

    Yamaha Civante part out value????

    You'll probably get the best value (and expend the least effort) selling the entire bike instead of parting it out. Parting bikes out really only makes sense if a) you're trying to keep some parts for a future build, b) have a particularly valuable part that you don't really want or c) the bike...

    Yamaha warranty. Something to consider. "Frame made wrong"

    Correct, most forks use a bottom race that is press fit onto the fork, which allows you to use different headsets. If the bearing-matching taper is actually built into the fork you may be SOL and need to wait on that warranty fork. Sorry. :/ I do think thats a dumb design if so. Its...

    Yamaha warranty. Something to consider. "Frame made wrong"

    Most manufacturers (even outside the big 3) are fine to work with and will ship out warranty parts, but they are totally reliant on the shop doing the work to figure out whats actually wrong and to document whats in need of replacing. Most companies aren't just going to randomly send out parts...

    Yamaha warranty. Something to consider. "Frame made wrong"

    Is there another Yamaha dealer anywhere nearby? Even if its a bit of a drive, I think its worth having someone else take a look at your bike. I think your dealer is either being shady or is just way out of their depth. Nothing you're describing makes any sense. If theres a reputable bike...

    Yamaha warranty. Something to consider. "Frame made wrong"

    I don't have a Civante, but just the noise can be a lot of things. Not sure what the beer can is supposed to show, but I've had bikes make similar noises to your bike when bottom bracket threads are dirty, pedal threads dirty, seatpost clamp lose/dirty, seatpost creaking in frame, saddle rails...

    Yamaha warranty. Something to consider. "Frame made wrong"

    I hear you, bike creaks are super annoying. They can also be incredibly difficult to nail down. Most bike frames are butted, meaning the metal is thicker at joints (because those are higher stressed parts of the frame) and thin in the middle to save weight. The center sections of bike frame...

    Yamaha warranty. Something to consider. "Frame made wrong"

    This thread is really weird. I'm assuming OP is new to riding and maybe something is getting lost in translation, but (to me) nothing so far says this is a Yamaha problem instead of a local shop problem. Is the frame broken? It doesn't look like it in the video, but its hard to say for sure...
