Inside, the small team manufacture and assemble all their own custom motors, battery packs, and belt drive transmission to run upwards of 750 watts through a shimano alphine hub, with clever sensor system to momentarily disengage the motor drive whenever the shifters are engaged.

Oh man I would love to get a factory tour there, 'tis not that far...

I hope someone is going to make belt gearwheels available that slide onto the splined freewheel where normally you 8/9/10 speed casette goes.
Then people can convert from chain to single speed with belt just by swapping out the chain wheels

(and I can use it to have belt-drive with my motors :mrgreen: )

You can get them already. e.g. : http://www.carbondrivesystems.com/products/overview
 
you can not install a belt drive on just any bike.. you must have compatible chainstays..
have you ever tried to remove the chain from your bike without separating the chain..;)
i don't think drive belts can be separated and then rejoined..

ah ha, now the "furry bike" makes sense..
it a snow bike with fuzzy battery insulation:)

Stunning Cube carbon frame with Bosch system :)

OK, this show is really big. People had warned that you need 3 full days to walk by and check out every booth at the exhibit. Here are a few of the gems and curiosities that stood out to me on my first day. Most ebikes at the show are very refined and running established drives like the Bosch system etc. but there are a few attempting to do things differently.

Here is an implementation of the always asked "why not put the magnets in the rim?" question. There wasn't too much technical detail, like whether it was an ironless coil system, and the wheel was fixed on the stand so I couldn't rotate it to get a sense of the cogging drag

This is taking the "all-in-on" ebike kit wheel up a notch by also including a solar charger in the mix. You can see the polycarbonate outer drum, and contained in that is a 12 watt solar array for trickle charging a battery, which itself is contained under solar cells, and then in the very middle is a geared hub motor. Notice the hollow axle but with no actual wires coming out. In the demo stand they had a wireless smartphone app throttle.

Here was one nicely made friction drive kit system, 2.4kg total weight battery included. It's low power, ~200 watts, and mechanically engages/disengages automatically on motor power.

There were about a half dozen different bafang mid-motor clones that were on display in the zeppelin room where most of the china/taiwan companies were located. But this one was no bafang clone at all. It's a german designed and german made mid-motor that mounts external to the chainring, using a special spindle and crankset but otherwise fits with a standard bottom bracket shell.

Also, I had no idea that Samsung was not just in the business of making ebike cells but also a proprietary drive system like the Bosch and Panasonic

But the day's highlight of course was meeting with italian ES member Panurge and riding around on his CNC machined 4kW Schumaker powered suspension bike. I then had the pleasure of seeing what 4kW will do to a rear wheel when the chain/rear derailleur is accidentally pushed into the spokes while throttling :shock:

Oh, and must not forget the snowboard bike!

Great impressions, great pictures, thanks.

I love that frame from Panurge, would make a perfect basis for a Telelever fork.
Also find the dual chain solution almost as good as the before mentioned Speedped design.

Other Canadiens there eh?


"... booth 407, hall A6 and at our outdoor booth for a testride with our D-Series bikes"

Interestingly, though they had a booth there were _very_ few complete ebikes at the show running with BionX drives. In previous years at Interbike that I've attended there were always a good number of commercial bikes with BionX hubs, but here the overwhelming majority here were Bosch or equivalent bottom bracket drives that have custom made frames. There were still a number of hub motor ebikes, but usually they were either generic import motors (often with some european branding) or familiar hubs like the same TDCM been used on the Stromer and A2B bikes. (http://www.tdcm-motor.com/products/electric-hub-motors/500w--rear-hub-motor/). I'll be Interbike again in a couple weeks, and will be curious to see how much of this trend is the same at that show or if there is much of a europe vs US divergence.

At least for BionX even if they are missing out on most of the recent OEM action, they sill have a healthy conversion kit business through bike shops, and I think that's probably a more stable business than supplying OEM's.
