Motors that can be purchased that are too on marketed motorbikes?

[oriol]

Hi!

It seems that to make a motorbike street legal, at least in Spain but probably this also applies to the whole EU, the motor and all the components have to be certified. The certification process is very costly, but if you can prove that the parts are used in existing marketed motorbikes, then all the parts are considered to be certified.

I am looking for any hub or mid brushless motor, that I can use on a 17" wheel. From what I can tell, I believe that some manufacturers are using QS hub engines with their own logo, but those I have found are only used in scooters.

Does any one knows, about any motorbike manufacturer, using a motor that we can buy for a DIY project that is mounted on a marketed motorbike, that meets the requirements above?

The only one I can think of is QS. Ideally it will be great, if the battery pack can be bought from the motorcycle manufacturer itself, because that way you do not need to certifiy the battery. Another option theoretical option will be to use a battery from a car manufacturer, since I believe the certification requirements for those are probably the same or more demanding, compared to a motorcycle battery.

So far I have looked into this manufacturers; Ebroh, Soco and Ovoabikes.

I have found that Soco uses a Bosch integrated drive, that greatly simplifies the connexion and wiring process, but sadly this device only provides 3Kw.

Any information will be welcome!

Cheers,

Oriol

You mentioned “scooter”, “motorbike”, and “motorcycle” in your post? What is a “motorbike”?

In english the word bike can refer to either bicycle or a motorbike/motorcycle. That is why I picked the word motorbike or motorcycle, which are perhaps less common than bike; to avoid the confusion with an electric pedal bike, or an unpowered bike.

A scooter tends to be a low power city bike, Vespa style with a step through frame. Since I am aiming to at least 7Kw, I was disregarding that particular type of motorbike configuration.

Cheers,

These guy's have likely all (out) sourced the motors? (from China? Ssssh!)
Then added a zero or 2 to the price.

So the question now becomes: Who (in China?) exactly..?

I dont believe zero sells their motors to end users anymore. There was some period of time roughly about 10 years ago where they used to do this but it doesnt appear to be the case anymore sadly...

Perhaps the motor comes from a donor bike?

They have not reply my email, but who knows perhaps they will?

If Zero motors is not an option, then apart from QS motors, I can try using a Lynch/Agni motor, but sadly those are brushed motors.

Perhaps find images of the motors and do an image search.

I'm wondering about how these compare to hub motors weight wise etc and especially price.

I'm wondering about how these compare to hub motors weight wise et

There are multiple factors:

--are all the motors being compared actually dyno tested for the comparisons you want to make?

If not, they probably can't be directly compared simply because most motors out there don't have *real* data on their capabilities, just what the marketing department thought sounded good. (and that's just for the manufacturer "spec", completely leaving out what sellers advertise)

--are they all running at the same RPM for the same power output?

If not, they can't be directly compared because the faster you spin it, the smaller the motor can be for the same power output.


Any non-hub motor that spins at a high RPM to provide more power at a lower motor weight will *also* require a reduction between it and the wheel to provide the correct wheel RPM. This will have some weight, so that weight must be added in when comparing, as does the weight of the mounting system and the drivetrain (chain, belt, shaft, etc) all the way from motor shaft to wheel hub.
