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
Oh, and must not forget the snowboard bike!
Currently in Turkey on the Suntrip tour
riding a back to back tandem solar powered row/cycle trike
. 550 watt solar roof, dual Grin All Axle hub motors, dual Phaserunner controllers, 12 LiGo batteries, and a whole wack of gear.
Waiting for me in Vancouver is a Big Dummy Frame (yes This One
, thanks ES!) with Grin all-axle front hub, Phaserunner controller, and 52V 19Ah Cellman triangle pack
