Hey thanks for chiming in guys!!
So I guess Safe is the only real failure story told, SO FAR
That's good. I wasn't aware of any load tests put on these, so thanks for that Mike, you should work for Consumer Reports.
But isn't Gary's system direct drive, so the torque load compared to say somebody using the Recumpence drive much less? And this guy down in San Diego, I havent seen or heard any other rport than Gary mentioning it in passing. I mean for all we know he could still have his sanity (think liability) and only be running 2kw through the Etek. I would definately be for thowing some money at somebody to destroy one of these (hint hint, nudge, nudge). So why don't we get a pot going to Mike or Thud to stomp these babys. I got $10 on it. Video would be requirement though.
So my argument has stood up thus far and the fact remains that we still lack an ebike gearbox, and only one shifting device has been constructed. I am waiting for an SA to show up as a jackshaft, but I think a major problem with that is the fact that the overall gear change would vary much more minutely (say that 3 times). Is that right? Like if it was 2:1 from motor to SA hub, then the end ratios would have only half the effect on speed.
Maybe this is the wrong section to bring this up, but wouldn't the most complete motor driven bicycle include both the motor, and a gearbox inside of it? If you could jam all this inside of the hub, and then make it strong enough to withstand a 10 foot drop with 200 #'s on it, you would have a world -beater. It would be the end all solution, the hub guys could finally say: "I knew they would come around eventually."
I think everybody is seeing it, but nobody is saying it. Make the damn thing huge out of billet aluminum, so what if it weighs 25 lbs, use the Axial Flux style motor sandwhiched between to different gear ratios, in however many layers as you wdeem necessary, the case will be expandable. You could even put two motors in there, they only weigh like 3 lbs each, the whole case is the sun gear, the annulus' (?) can be extron because they dont have to be tiny, have that motor screaming away at 8000 rpm, delta/wye switch for 4 speeds, which will be more than plenty for bursts to 100 mph. If you build this gentleman, I know a line of investors will form here to get on board. How much will people pay? Thats not the question, how many will be put in the crusher
for street racing rice rockets? hahaha, yeah!!
People wonder what I see on here, and are like Electric Bike haha, cute. But what I see is a community, sharing, giving, expanding, and evolving. Evolving the form of tranportation that most people can't even imagine. Being here in this age, is like glimpsing for a second into the future. Truly I am blessed to be in the company of such a crowd. That was me giving Thanks, now lets eat some turkey!!!
