Actually, this form does spell it out: https://www.massrmv.com/rmv/forms/21897.pdf If the bicycle has two or three wheels, an automatic transmission, a cylinder capacity of not more than 50 cubic centimeters, and a maximum speed of 30 MPH or less, it must be registered as a Motorized Bicycle...

There seems to have been an explosion of new ebikes and advancement over the last year or two, which might be why you don't see a lot of long term reviews on all these recent new products. That been said, the previous gen of Bosch motors for instance had some sort of issue (I don't recall the...

Couldn't open the link for some reason, but seems like an odd reason. Bosch motors seem to be pretty well integrated from many bike manufacturers, and with the new powertube batteries coming - it doesn't get much more integrated than that.. That been said, I do like the look of the new BMW...

Wow, you drew up all that from a simple little electric ebike motor with automatic gearing...? You honestly can't appreciate why someone might be interested in a commuter bicycle like this, where in addition to not shifting, maintenance and cleaning is much simpler? Cockpit clutter is reduced...

That's the line of thought I had when I looked up the specs, yes. When I read your original post, I was thinking along the lines of popular mid drive motors such as Bosch, Yamaha, Brose. You could always reach out to the manufacturer though, and get the word straight from the horses mouth.

Very interesting bike, but I feel it would be a requirement to grow a mustache in order to ride the thing :|D I like the looks of the thing. That top chain cover is interesting. And is that some sort of immobilizing / anti-theft device on the back tire?

If your only hauling the one kid, check out the elBoda Boda and accessories. There is a monkey bar set for it, and many other accessories. You can haul up to 220lbs on it plus the rider. http://yubabikes.com/cargobikestore/elboda-boda

My wife and I have a Yuba Mundo V4, which I upgrade to a pedal assist e-bike. We can haul a couple kids plus our toddler in a child seat pretty easily. If your daughter doesn't have any issue siting up (inside the optional monkey bars), I can wholeheartedly recommend it...

You might want to consider looking at a different bike then. Like I mentioned, that is a pretty low power hub motor. If you want 32km/h, take a look at something setup for it, there are plenty of options out there.

People will always scrutinize something based on their own wants /needs. The bikes intended market does clear things up a bit though. That been said, I do really like the geometry, and I can definitely see some Stromer in there. That new Shimano motor sounds pretty sweet. If this thing were...

If that's your use case scenario, then even the 25km/h limitation should be fine. Do you need to go any faster than 25k going up hill? That's the great thing about all the new ebikes coming out these days. There really is something for everyone :)

Nice looking bike, hub based motor rather than mid drive. The motor is from ebikemotion out of Spain. Looks like a 36v 250w motor with 40nm of torque (a little weak), and the battery is just 250w. That little hub motor might not be able to handle speeds greater than 25km/h, and with that...

Ya, I agree. Looks more suited as a class 3 45km/h style of commuter in my opinion. That I would be interested in (if we had the option here in Canada).

Curious, which bike are you looking at?

You are correct that it is limited in the software. In Canada, 32km/h bikes are the only ones that are permitted. Those are typically powered by the same motors as the 25km/h ones in Europe (250w nominal). I seriously have my doubts a dealer would be able to update the software for you, and...

No, it's the Tongsheng kit from Biktrix. Installed on a Yuba Mundo. It's a big / heavy cargo bike, so that's why I thought I would have to decrease the front chain ring. I didn't, the thing climbs hills like a boss with the 46t front ring and she doesn't even have to drop down to the lowest...

I'll admit, that confuses me. My Bosch powered bike came with a 15t ring, which I upped to a 17t one. Delimited I can hit up to 60km/h before running out of gear with a basic 10 speed Deore drive train that has a 11t smallest in the back. On my wifes bike I did a conversion on, the motor came...

LOL, fair enough.. I still kinda have my doubts though. I mean that large cog is bigger than the brake disc, which you would need if you didn't have motor assist..

Also, anyone else think that rear cassette is a little odd for a commuter style of e-bike? Why would one a large climbing ring that large on a city commuter with a powerful pedelec motor? I barely ever use the largest one on mine, and it's much smaller than that. In fact, I had to increase...
