Another e-mtb. :rolleyes: I wanna see more road bikes, damnit!

Good looking bike. Google teases with images of some other Panasonic e-bikes as well, but trying to find any info is an exercise in frustration.

Yeah I thought about that, but in my personal opinion, ebikes kind of make road bikes obsolete.
On my Juiced, I pass road bikes all the time.. the only reason I would be interested in the road bikes would be the speed. But ebikes can give you just that.
Unless you like the riding position or style of road bikes though.. but not for me.

Also this is not just another eMTB though, it's powered by Panasonic multi speed drive.
So in terms of power source, it is kind of unique.

The Panasonic multispeed drive is actually one of the best drives out there IMO. It totally solves the N380 hill climbing issue, and allows you to have speed and hillclimbing ability even with an IGH. You can set the drive to autoshift and it will downshift at a red light. The question is: will Panasonic be able to convince manufacturers to jump on board. One critique about the MS drive is that it’s noisy. It’s easy to learn about this drive: it equips the Flyer Upstreet 5 in the high end S-Pedelec configurations. People on the German Pedelec forum have given some feedback. It’s a popular system in Switzerland because Flyer gives an extended warranty on the drive (5 years on city bikes), and also because the drive accelerates fast and can get started on hills easily. The battery is also the same as Flyer from what I can see: SIB-630. Only Flyer’s Nyon-like 3.5” color display seems to be unique to Flyer. Haven’t seen it on the other Pana systems so far...

So JayVee is there a gear reduction within the motor? I wonder what the total weight of the motor system is?

My biggest complaint is that they use a square taper bb spindle rather than an ISIS type.

I don't know about the motor but the XM-D2 weighs 57.76 lbs which is not too bad for a full suspension eMTB.

Yup, the gear reduction is inside the drive. The speed drive has 2 gears with 35T and 48T. The gearing for the all terrain version is different. The drive weighs 4.8 kilos, which means it’s not really well suited for a pure mountain bike drive. It does have muscle though, and the 350W is a little deceiving.

Univega & Van Dessel will be using the Panasonic system, it doesn't look the same as XM-D2 though.
(I don't know if Univega & Van Dessel are the same company or two different companies)

A two speed internal transmission with added complexity versus a two front chain ring on say, a Yamaha PW set up. Thinking.....:rolleyes:

Aside from that, here comes another long historied company with a great reputation here in the US added into the mix of ebikes. And to think, an actual factory in the US that builds ebikes!

We are witness to a great technological war going on in the bicycle industry right now. And I love it!

Kent International controls both brands. The are based in New Jersey and their manufacturing facility is in South Carolina. They are primarily known for producing Big Box store type bicycles but have entered into a partnership with Panasonic for the Van Dessel, actually a well respected brand in the bicycle world, and Univega, one of the early names of MTB, brands they control.

I found a good explanation of the 2spd system here: https://eu.industrial.panasonic.com...es/downloads/files/catalogue_2016_english.pdf

It says the internal transmission will contribute to the energy efficiency.

Also, I am not sure how it works, but if it could work like an automatic transmission with torque sensor, I guess the same 350W motor can go on high torque setting when you're at lower speed, then when you're at higher speed, the internal gear can change to assist more top speed.

I know 2 speed doesn't sound like many (only high and low gear) but when you look at some of the RC cars, having high and low gear really makes the difference.

Compare it with a single speed unit like Bosch, Shimano, Brose and Yamaha.
I bet the 2 speed Panasonic has an advantage because it can go on both torque biased or high speed biased setting.

Here are the promotion vidos:
I have purchased this from Bic Camera last weekend, but I am not sure when it will arrive. It says "Early March". Panasonic's site says "Goes on sale March 1st", so my guess is it will arrive in the nest two weeks. I'll let Ya'll know how it is, but one negative point I can guess is that it doesn't look like it has a kick-stand option. Given that the tires are too wide to fit in most bike racks in Japan, I would have to park it in the motorcycle spaces, which means it has to be able to stand up.

I am not sure why, Panasonic's site has all the info. Even if you don't read Japanese, Google does, and most of the info you want is probably specs, written in numbers anyway. What information are you looking for?

FYI The specs list it as 250W, which makes sense, because that is what the XM-2 uses, and Panasonic said this is the same drive unit as the
XM-2. (Also I believe there is a statutory restriction, though reading the law only indicates power ratio, rather than absolute limit).

I have the XM-1 now, which is single speed, and I have never felt it needed more speeds. I suppose it depends if you will be climbing 60 degree inclines. I will let everyone know my impression after the XM-D2 arrives.

Well they were going on about how the paint is sort special and looks different from different angles, etc., but I figured that's just marketing.

Here are some photos in the daylight, before I scratch it up.

It won't be until next weekend that I have time to try it out on a trail, but today I will ride it to Shibuya. Problem number one : with fat tires I can't park it at bicycle parking. With no kickstand I can't park it at motorcycle parking, so... I can't actually ride it anywhere around town at the moment. I would like to get a motorcycle style center stand, but there is just really no clearance.

I'll probably opt for something that's easily removable for when I am actually going to ride on trails.
