Looks like a couple of hastily cobbled together bikes to display the drive unit..... :)
 
They have a number of patents...

I like the concept, but with styling only an engineer can appreciate it just can't become very popular in the west. I'm sure someone is going to wise up and hire some design people. Between stuff like this and the gaudy crosses between scooters and ebikes that can only be popular in China, there's a huge opportunity just sitting there waiting for someone to seize it.

Nice timing though Miles. I was just pondering how to install a compact ventilated hub motor with a housing to filter the air intake right near a bottom bracket.

Not sure what you mean.... It's a German company.....

The unit uses a motor running at 3000 rpm, with 3 chain stages to reduce it to crank rpm.
 
The frame on that mountain bike is VERY Ducati motorcycle like isn't it

The cruiser looks pretty scwheet too IMO..

The silver bike's drive unit enclosure looks like someone's home project.

The first thing I thought of when I saw that red bike was "PC tower/case!"...Are they strapping Alienware PC towers to the downtubes of bikes these days? The drive unit is awesome, but putting them on bicycles seems like a major afterthought. The frame looks kinda cool, but too much extra tubing (over-engineering?). It would look better without the drive unit...and the drive unit would actually look better without the bike :) With that being said, I want to see them put one on a Yuba Mundo style frame.

I mean they're ugly, obviously no artistic input. Ebikes aren't going to really take off until someone steps in with slick styling and better utility than just a bike you don't have to pedal. It wasn't just a conspiracy that sank the EV1, someone high up in GM didn't like the style too, not slick enough.

ever seen a toyota corolla ? i first car i had . 73 puke yellow corolla , ugly as sin but ill tell ya it NEVER broke down , worked every time i put the key in it and got great mileage.

corolla's have done rather well

style dont mean shit . if it works and works hard it will sell.

all the tubing and structure, where the batteries and sensitive stuff is looks like the best place to put it . If i wasnt into making my own id ave bought one of these . My only question is how hard is it to bolt high output motors (ie: beyond legal limit) to it ?

first impression is much better than the wirless bike some canadian outfit is making.

Mmm...I like that one. I REALLY like that one.


Doesn't look that dissimilar to my bike.


And no Kim, I'm not married to Hub motors, it's just with my frame, and reliability requirements, it's the best match for me right now.


I'd like a serial setup with a belt drive to a 7-8 speed rear hub. But I can't package it easily with my dually with the current solutions. Maybe motor in front, but that's vulnerable.

But the batteries/fuel cell + petrol are too far forward, they will get crushed going over a log, or up a gutter.
 
Well....... it's not about those bikes, it's about the drive unit....

Anyway, their own examples prove that there is a problem with integrating the unit, in its present form.......
 
As far as appearances, it shouldn't be difficult for the factory (or aftermarket suppliers) to cobble together some attractive pop-on "skins" of fiberglass or injection-molded plastic that would look better than the stock bare vehicles...

The drive unit seems sensible, but i am going only by the post trike. The rear hub seems to be a NuVinci, and the fuel cell probably an EFOY Pro (specs here). It's an interesting solution for a transport bike doing a lot of stop/start work where charging isn't available, because the cell can charge all the time. It uses just under a litre of fuel per Kw/hr, but at nearly 20lb weight for 90 watts continuous output, possibly not a good match for a sport bike being ridden hard continuously. If, say, you are using 360 watts it will only increase your range by a third, and if you would have to wait three hours to recharge for every hour you rode.
 
Better, at least for those who like the cruiser look, but what's with the engineering mistakes?...The controller way up at the handlebars, and the battery unnecessarily higher than needed. Make it all one compact unit with only low current wiring going out away from the primary unit, though I guess having the battery a separable unit to make placement easier in a variety of bike frames makes sense, just not up high on that cruiser.
 
..If I understand correctly the pg-bikes.com uses the Clean Mobile motor, the Clean Mobile BB drive unit, the name Miles used for the thread. It's not like the Clean Energy prototypes in any other way. There is no fuel cell, no NuVinci .... This is just somebody's ebike that uses the CM BB Drive motor. There are BB drives from across the other ocean (for us Yanks) like the Sunstar that seemed to capture efficiency in a BB motor better than a Clean Mobile with a NuVinci as an ADD ON does . They haven't made it.

..Maybe it is glitz that allows a product to grow and mature. If so, MORE POWER to the glitzers. To this old house, this looks like the same old same old. Now maybe the Clean Mobile accomplishes the same thing as the Sunstar. I didn't read all of the patents Miles listed. I could be wrong, but a lazy old fart like me could glance and see the value of Sunstar. When I glance at Clean Mobile, I see glitz.

For those like me wondering, it seems the 3rd-Element eSpire retails for around 7,000Euro or ~8,400USD under current exchange rates/excluding shipping. (Don't forget this includes 820Wh of lipo and a Rohloff hub with some sort of auto-electronic shifting - like the Nuvinci Electronic Shift Controller/actuator option seen Here)

http://3-element.com/blog/?cat=8&lang=de Typical, European distributors only so far...... :roll:

.....So price wise it seems to slot in between the other two boutiques, the Stealth-bike and the Optibike.

They claim 60kph top speed for 'tuned model', Motor is spec'd at 1.2Kw on a distributors webpage (but not company page), 48V, and somewhere - after god knows which stage in the gearing- it can supposidely produce up to 150Nm of torque. I'm guessing @ the rear wheel/1st gear?

If only clean mobile would sell the drive unit separately to non OEM's.....

To me, the frame itself is sexy, but the battery enclosure ruins the overall look.
I reckon it could be easily improved - both aesthetically and practically - by relocating the lower half of the present battery pack/enclosure into the space-frame higher up. No more ploughing of rocks with the battery enclosure under full suspension travel, It would look less bulky and the weight distribution would still be pretty darn good. (Centralised rather than the lowest possible centre of gravity is arguably better for lean-in...when seated at least)

If you're going to the trouble of a completely integrated drive system, the approach taken by j3tch1u and Hal makes more sense than the CleanMobil /Optibike one - to me, anyway....
 
Hey, totally agree. Im just looking for something of high quality and performance i can buy off the shelf......now. Optibike is overpriced for what it is, but If the stealth creator would ditch the frock and run an integrated lightweight/compact RC drive through the V-boxx (assuming it could take the added load) id buy one yesterday.
 
hmm, i wasn't aware the drive units were freely available off the shelf. I just assumed the company would only sell replacements to those who had already purchased the whole bike.
