    Heres some real world ebike motor data.

    The fact is that a 6% downhill grade will result in a coasting speed of 30mph on a mtn bike and a bit faster on a road bike with ZERO rider pedaling. That is a fairly common hill grade in most cities so bikers do coast down those hills and hit a top speed around 30mph unless you are suggesting...

    Heres some real world ebike motor data.

    You seem to imply that 20mph is "fast enough" going down a hill on a bike. Do you understand that if that hill is over a 3 percent downhill grade that most riders would have to be braking the entire time down that hill to not go faster than 20mph. A 6 percent downhill grade results in speed...

    Heres some real world ebike motor data.

    That study result is real - there was a cumulative distribution of the top speed hit by riders on non-bikes on typical rides. On downhills the top speed of the majority (like over 95%) was around 28mph. It was not an average speed, just the top speed. If you just simulate what a long 6 percent...

    Heres some real world ebike motor data.

    Yes. I agree. The funny thing is how many commenting in this forum seem to think that 750W is just too much power to be a bicycle. That power is best utilized to increase the average speed up hills and not about increasing the top speed riders to. There is one fact that many people ignore - a...

    Heres some real world ebike motor data.

    NO NO. In 2002 congress passed HR727 one vote short of full consensus that a LSEB with 750W rated motor (power limited above 20mph) was same as a bike. We can sit here on EBR and debate when motor power goes from being OK to be a bike to when it's high enough to be considered a moped /...

    Heres some real world ebike motor data.

    While 250W EU spec motors is "good enough" for recreational / mtn ebikers it simply is not adequate for an effective urban mobility solution. If an ebike is to have enough merit to get people out of a car for some trips / commutes from home they need to be able to average faster speeds like...

    Confusion on trail rules?

    Why is it that so many think they should decide if someone with a disability should be allowed to ride an ebike? Some may just have knee issue so they can't put a lot of power into the cranks and need a throttle. So why is it a problem that a 750W 20MPH throttle-assist ebike can ride where a...

    Better thumb throttle?

    I know PIM / Polaris ebikes had a really nice thumb throttle but they are no longer producing ebikes. It was sensitive and had just enough resistance to make if very responsive at the same time. It's the best I've tried. I like grip throttles too but they make the grips a larger diameter which...

    Confusion on trail rules?

    Not really sure how an ebike not being powered is different than a bike. I have always questioned the logic of class 1 and 2 being considered different for trail use considering how the drive system tech can really gray the distinction of what a PAS and throttle-assist ebike is. Regardless...

    Will Ebikes become a fad in the US?

    Were they riding compliant ebikes?

    Confusion on trail rules?

    How does someone know if the ebike is turned on?

    Confusion on trail rules?

    There in lies the problem - there is no reason whatsoever for a compliant HR727 LSEB to be treated as anything but a bike nationally (it passed just one vote short of congressional consensus). I know some argue that each trail is different ... then set speed limits on all bikes using those...

    Confusion on trail rules?

    Instead of pushing the nonsensical 3-class system People for Bikes should have just ensured that all states cleaned up their "use regulations" to allow a compliant LSEB to be used as a bike which is what was intended by HR727. Sadly the one time bike advocacy group became an industry lobby...

    Confusion on trail rules?

    The federal definition in HR727 defines a compliant "low speed electric bicycle" as a subcategory of bicycle...specifically saying they are not to be considered motor vehicles. I would have rode that day on my compliant LSEB as someone needs to push this. HR727 passed congressional voting one...

    Are Class 3 ebikes that are programmable to Class 2 legal in NY state? ie Ride1up or others?

    I have posted a lot of regulatory posts on EBR so I'm well known on this forum for supporting the federal HR727 definition of a "low speed electric bicycle" as a bike. It's seems like a strange specification / definition but the constraints set a power limit above 20mph that allowed a universal...

    Are Class 3 ebikes that are programmable to Class 2 legal in NY state? ie Ride1up or others?

    The class system does not make it clear if a bike can have multiple program class modes so I would assume that a Class 3 ebike with programming to enable a class 1 or 2 mode as compliant to ride in NY. Eventually the multi-mode issue will end up in court so until then some brands are going to...

    Mid Drive Bike Suggestions

    Buy a Sondors model with the Bafang M620 / Ultra. Regardless that the 250W EU mid-drives are good for mtn bikes if you plan to use the bike for transportation you will learn to desire the higher power the US regulations allow.

    New motor: Made in Canada, 2022 Mid-drive system

    This came up as a result of the new dual drive system only having a throttle to begin with and the future option to add PAS. Here's what a professional says about cadence (not from me). When pedals are turned slowly with lots of force, muscles tire quickly – not getting enough oxygen and blood...

    New motor: Made in Canada, 2022 Mid-drive system

    But the programming has to make assumptions about how much assist is desired based on a sensor parameter that is not tied to rider effort in reality. I understand it can be done to provide a good assist sensation but I fail to see that this is even remotely as good as just giving the rider...

    New motor: Made in Canada, 2022 Mid-drive system

    I do just fail to understand how a cadence only PAS system is a viable solution. Cadence speed as I see it has little correlation to what assist a rider might want. I know I quickly found out that I didn't like my ebike that just used cadence as an on/off switch for the 5 different levels of...
