New record heavyweight eBike @ 84 pounds ?

Stefan,

If I'm right, Mike_V has a Frey HT1000. So the motor would be a Bafang MM G510 (1000W/Max Torque 160NM).

tNot a record , Sondors LX is 89.2 pounds and it's not a cargo bike !

The claimed weight of my former Maxfoot cruiser was 82#, unpowered it was hard to pedal.

Stefan,

If I'm right, Mike_V has a Frey HT1000. So the motor would be a Bafang MM G510 (1000W/Max Torque 160NM).

So he cannot compare it to the cargo ebike with the motor of peak power of some 500 W and torque of 80 Nm. Not only because the Pakyak would be heavily loaded but also because of air drag.

Also, Mike was wondering why Giant Trance E+ required a strong rider to get at 35 mph. That's because peak power of Yamaha PW-X2 was 520 W. The air drag requires power increase in cube of the air velocity. Add to it the necessary cadence, I think 120 rpm with the MTB gearing. (My brother can input over 500 W with his legs in burst and I can prove it).

You wouldn't be able to accelerate that cargo e-bike to 28 mph even partly loaded. People often think the 28 mph is the promise. It is not. It is just a theoretical motor assistance speed limit.

What seems to be very strange there is the fact the Yamaha PW-X has never been a Class 3 motor...
P.S. Momentum website never mentions the e-bike Class or speed limit. Check the Momentum Bikes website for the United States. (I wonder how @Court got that information).

Yep, Yamaha PW-X can't do 28mph out of the box without being chipped. Then throw that weight on that motor and try to get that speed. I'm a little skeptical.

What power and what torque of that motor?

I don't see a proper bulky cargo 'trunk', just top heavy baskets, maybe a trailer is optional.
I read the regulations riders face in Europe and cringe.
Mine is Luna 'tuned' cadence PAS BBBS02 & Luna 52V Wolfpack I love riding fast while I pedal slow.
Enjoy
Mike
